Description

Technical Field

[0001] The present application relates to the technical field of MBBR sewage treatment, and in particular to a sewage treatment system and a sewage treatment control method based on MBBR. Background Art

[0002] The MBBR process principle is to use the basic principle of the biofilm method, fully utilizing the advantages of the activated sludge method and overcoming the shortcomings of the traditional activated sludge method and fixed biofilm method.

[0003] This process increases the biomass and biological species in the reactor by adding a certain amount of suspended carriers to the reactor, thereby improving the treatment efficiency of the reactor. Since the density of the filler is close to that of water, it is completely mixed with water during aeration, and the environment for microbial growth is a three-phase gas, liquid, and solid. The collision and shearing effect of the carrier in the water makes the air bubbles smaller, increasing the utilization rate of oxygen. In addition, each carrier has different biological species inside and outside, with some anaerobic or facultative aerobic bacteria growing inside and aerobic bacteria outside. In this way, each carrier is a microreactor, allowing nitrification and denitrification reactions to exist simultaneously, thereby improving the treatment effect.

[0054] The embodiments of the present application provide an embodiment of a sewage treatment control method. It should be noted that, although a logical order is shown in the flow chart, under certain data, the steps shown or described may be completed in an order different from that shown here.

[0055] Before introducing the sewage treatment control method of the embodiment of the present application, the application scenario of the sewage treatment control method is first explained. The sewage treatment control method of the present application can be directly applied to a sewage treatment system based on MBBR, and can also be applied to smart phones, tablets, computers and other smart terminals, and can also be applied to servers. The present application is not specifically limited here, as long as it can carry and implement the sewage treatment control method of the present application.

[0056] The following description will be given by applying the sewage treatment control method to the server side, but it should be understood that the sewage treatment control method is not limited to being applied only to the server side.

[0057] Combine the following Figures 1 to 9 The present invention describes a sewage treatment system and a sewage treatment control method based on MBBR.

[0058] According to the embodiment of the first aspect of the present application, Figure 1 As shown, the sewage treatment control method is used for a sewage treatment system based on MBBR, and the sewage treatment system based on MBBR includes:

[0059] The sewage treatment tank 110 is formed with a sewage treatment chamber 111, a plurality of first pipes 112 are evenly arranged at the bottom of the sewage treatment chamber 111, each of the first pipes 112 is provided with at least one first electronic valve 113, a plurality of second pipes 114 are evenly arranged at the sidewalls of the sewage treatment chamber 111, each of the second pipes 114 is provided with at least one second electronic valve 115;

[0060] The water pumping sampling assembly 120 includes a water pumping pipe 121 and a water pump. The first pipe 112 and the second pipe 114 are both connected to the water pumping pipe 121. The water pump is connected to the water pumping pipe 121. The water pumping sampling assembly 120 is used to obtain sewage samples at different positions in the sewage treatment chamber 111.

[0061] The air supply assembly 130 includes an air supply pipe 131 and an air pump. The first pipeline 112 and the second pipeline 114 are both connected to the air supply pipe 131. The air pump is connected to the air supply pipe 131. The air pump is suitable for delivering gas to the first pipeline 112 and the second pipeline 114 through the air supply pipe 131.

[0062] A suspended carrier is located in the sewage treatment chamber 111, and the suspended carrier is used for sewage purification;

[0063] The control element, the first electronic valve 113, the second electronic valve 115, the water pump and the air pump are all electrically connected to the control element;

[0064] The control element is used to control the opening and closing of different first electronic valves 113, the opening and closing of different second electronic valves 115, and the operation of the water pump, so that the water sampling component 120 can sample sewage at different positions in the sewage treatment chamber 111. The control element is also used to control the opening and closing of different first electronic valves 113, the opening and closing of different second electronic valves 115, and the operation of the air pump, so that the gas delivery component 130 can deliver gas to different positions of the sewage treatment chamber 111. The control method includes:

[0065] Step 101, obtaining detection results of sewage samples at different positions of the sewage treatment chamber 111;

[0066] Step 102: Determine the sewage treatment effect at different positions of the sewage treatment chamber 111 based on the detection result;

[0067] Step 103: determining a target location based on the sewage treatment effect, wherein the sewage treatment effect of the target location is lower than a threshold;

[0068] Step 104: Deliver gas to the target location.

[0069] According to the sewage treatment control method of the embodiment of the present application, sewage samples at different positions of the sewage treatment chamber 111 are tested to obtain test results, and the sewage treatment effects at different positions of the sewage treatment chamber 111 can be determined according to the test results. The position where the sewage treatment effect is lower than the threshold is determined as the target position. Gas is transported to the target position, and the gas is used to drive the liquid flow at the target position to improve the sewage treatment effect.

[0070] It is understandable that the sewage treatment effect is generally reflected in specific parameter values. If the corresponding parameter is lower than the threshold, it means that the sewage treatment effect is lower than the threshold.

[0071] In one embodiment of the present application, after the step of determining the target location based on the sewage treatment effect, the method further includes:

[0072] Based on the target location, determine the target area;

[0073] Controlling and increasing the density of the suspended carrier in the target area.

[0074] It is understandable that the purpose of improving the sewage treatment effect can also be achieved by increasing the density of the suspended carrier.

[0075] According to the embodiment of the second aspect of the present application, the sewage treatment control device and the sewage treatment control method correspond to each other. Figure 2 As shown, the sewage treatment control device is used in a sewage treatment system based on MBBR, and the sewage treatment control device includes:

[0076] An acquisition module 201 is used to acquire detection results of sewage samples at different positions of the sewage treatment chamber 111;

[0077] A first determination module 202 is used to determine the sewage treatment effect at different positions of the sewage treatment chamber 111 based on the detection result;

[0078] A second determination module 203 is used to determine a target location based on a sewage treatment effect, wherein the sewage treatment effect of the target location is lower than a threshold;

[0079] The control module 204 is used to deliver gas to a target location.

[0080] According to an embodiment of the third aspect of the present application, Figure 3 and Figure 4 As shown, the MBBR-based sewage treatment system includes:

[0081] The sewage treatment tank 110 is formed with a sewage treatment chamber 111, a plurality of first pipes 112 are evenly arranged at the bottom of the sewage treatment chamber 111, each of the first pipes 112 is provided with at least one first electronic valve 113, a plurality of second pipes 114 are evenly arranged at the sidewalls of the sewage treatment chamber 111, each of the second pipes 114 is provided with at least one second electronic valve 115;

[0082] The water pumping sampling assembly 120 includes a water pumping pipe 121 and a water pump. The first pipe 112 and the second pipe 114 are both connected to the water pumping pipe 121. The water pump is connected to the water pumping pipe 121. The water pumping sampling assembly 120 is used to obtain sewage samples at different positions in the sewage treatment chamber 111.

[0083] The air supply assembly 130 includes an air supply pipe 131 and an air pump. The first pipeline 112 and the second pipeline 114 are both connected to the air supply pipe 131. The air pump is connected to the air supply pipe 131. The air pump is suitable for delivering gas to the first pipeline 112 and the second pipeline 114 through the air supply pipe 131.

[0084] A suspended carrier is located in the sewage treatment chamber 111, and the suspended carrier is used for sewage purification;

[0085] The control element, the first electronic valve 113, the second electronic valve 115, the water pump and the air pump are all electrically connected to the control element;

[0086] Among them, the control component is used to control the opening and closing of different first electronic valves 113, the opening and closing of different second electronic valves 115, and the operation of the water pump, so that the water pumping sampling component 120 can sample sewage at different positions in the sewage treatment chamber 111. The control component is also used to control the opening and closing of different first electronic valves 113, the opening and closing of different second electronic valves 115, and the operation of the air pump, so that the gas delivery component 130 can deliver gas to different positions in the sewage treatment chamber 111.

[0087] According to the MBBR-based sewage treatment system of the embodiment of the present application, the sewage treatment chamber 111 is evenly divided into multiple areas through the first pipe 112 and the second pipe 114, and each area corresponds to at least one electronic valve. In actual use, the control unit controls the water pump to start working, and at the same time controls one of the electronic valves to open, so that the water pump can extract sewage from one of the areas of the sewage treatment chamber 111 corresponding to the electronic valve, and achieves the sampling of sewage in one of the areas of the sewage treatment chamber 111, and then controls the electronic valve to close, and controls another electronic valve to open, so that the water pump extracts sewage from another area of ​​the sewage treatment chamber 111 corresponding to another electronic valve. After a certain period of extraction, sampling is performed again to avoid the influence of sewage in one area. By analogy, targeted sampling can be performed on different areas of the sewage treatment chamber 111, which is conducive to accurate detection of the sewage treatment chamber 111, and it can be known which areas have poor sewage treatment effects.

[0088] After testing the extracted water samples, it can be determined that the sewage treatment effect in some areas is poor. The electronic valve corresponding to the partial area is opened by the control component, and the air supply component 130 is controlled to start working. The gas can be delivered to the partial area through the first pipe 112 and / or the second pipe 114 to improve the liquid fluidity in the partial area to improve the sewage treatment effect. Oxygen can also be delivered to the partial area in a targeted manner to improve the sewage treatment effect, thereby realizing targeted treatment of the sewage treatment chamber 111. The first pipe 112 and the second pipe 114 are used for water sampling and gas supply, so that the pipes are shared and the structure is simplified.

[0089] It is understandable that when using a suspended carrier to treat sewage, the sewage treatment effect in different areas may be different. For example, the oxygen content in some areas may be insufficient, which in turn affects the treatment effect of the suspended carrier on sewage. At this time, it is necessary to increase the oxygen content in the area. In the related art, only the oxygen content of the entire pool body can be detected, and the oxygen content of the entire pool body can only be increased or decreased. It is difficult to detect the oxygen content of a certain area in a targeted manner, and it is also difficult to increase the oxygen content of a certain area in a targeted manner. In this application, the water samples of different areas can be sampled through the cooperation of the water pumping sampling component 120 and the electronic valves at different pipelines, and targeted detection of different areas can be achieved. At the same time, through the cooperation of the air supply component 130 and the electronic valves at different pipelines, gas can be delivered to a specific area, and then the oxygen content of a specific area can be controlled, and the situation where the oxygen content of some areas is too high due to increasing the oxygen content of the water in the entire pool body can be avoided.

[0090] Exemplarily, the plurality of first pipes 112 are connected to the first main pipe, and the water pumping pipe 121 and the air supply pipe 131 are both connected to the first main pipe. The plurality of second pipes 114 are connected to the second main pipe, and the water pumping pipe 121 and the air supply pipe 131 are both connected to the second main pipe.

[0091] In one embodiment of the present application, each first pipe 112 is provided with a plurality of first electronic valves 113, and the plurality of first electronic valves 113 are evenly arranged along the length direction of the first pipe 112; each second pipe 114 is provided with a plurality of second electronic valves 115, and the plurality of second electronic valves 115 are evenly arranged along the length direction of the second pipe 114.

[0092] It can be understood that by evenly arranging a plurality of electronic valves in each pipeline, the sewage treatment chamber 111 is divided into a plurality of small areas, which is beneficial to the precise treatment of the sewage treatment chamber 111.

[0093] In one embodiment of the present application, an air pressure detection component is provided in the air supply pipe 131, and the air pressure detection component is used to detect the air pressure in the air supply pipe 131. The air pressure detection component is electrically connected to the control component, and the control component is configured to control the opening and closing of the first electronic valve 113 and the second electronic valve 115 based on the detection data of the air pressure detection component.

[0094] It can be understood that, according to the cooperation between the water pumping sampling component 120 and the electronic valve, water in different areas of the sewage treatment chamber 111 is sampled and tested, and according to the test results, some areas with poor sewage treatment effect are determined as target areas, and the first electronic valve 113 and the second electronic valve 115 corresponding to the target area are target valves.

[0095] The control component can control the air pump to start working, and the target valve is in a closed state at this time. When the control component determines that the air pressure is greater than the preset value according to the detection data of the air pressure detection component, it means that the first pipeline 112 and the second pipeline 114 are both full of gas at this time, and the air pressure is the same, then the control component controls the target valve to open, ensuring that the pressure and flow rate of the gas output from different target valves are the same, ensuring the consistency of the treatment effect on different target areas;

[0096] The control component can also determine the total amount of gas required for different target areas based on the detection results of different target areas, and then control the air pump to work so that the air pressure in the first pipeline 112 and the second pipeline 114 reaches the preset value, so as to calculate the amount of gas output through the electronic valve, and then control the first electronic valve 113 and / or the second electronic valve 115 corresponding to the different target areas to open in sequence, that is, first control the electronic valve corresponding to one of the target areas to open, so as to replenish the gas in the target area, and then close the electronic valve, and then control the electronic valve corresponding to the next target area to open, so as to replenish the gas in the next target area, and so on, so as to achieve targeted gas replenishment for different target areas.

[0097] In one embodiment of the present application, the MBBR-based sewage treatment system also includes an injection assembly 140, which is installed on the wall of the sewage treatment chamber 111. The injection assembly 140 is used to inject water or gas into the sewage treatment chamber 111 to drive the suspended carrier in the sewage treatment chamber 111 to move.

[0098] It is understandable that the suspended carrier can be driven to move by the injection assembly 140, that is, part of the suspended carrier can be moved from the current position to another position, thereby controlling the density of the suspended carrier at different positions in the sewage treatment chamber 111. In this embodiment, the density of the suspended carrier in the area with poor sewage treatment effect can be increased by the injection assembly 140 to improve the sewage treatment effect in the area.

[0099] It is understandable that when the injection assembly 140 drives the suspension carrier to move, it also drives the sewage in the sewage treatment chamber 111 to flow, thereby improving the fluidity of the sewage and being beneficial to improving the sewage treatment effect.

[0100] It is understandable that when the oxygen content in the sewage treatment tank 110 is insufficient, the injection assembly 140 can inject oxygen to drive the suspended carrier to move, and at the same time increase the oxygen content in the sewage treatment chamber 111.

[0101] In one embodiment of the present application, the injection assembly 140 includes an injection member, one end of which is used to suck the sewage in the sewage treatment chamber 111, and the other end of the injection member is used to spray out the sucked sewage.

[0102] It can be understood that by driving the suspension carrier to move through the sewage in the sewage treatment chamber 111, the sewage treatment effect can be prevented from being affected while driving the suspension carrier to move.

[0103] In the embodiment of the present application, the injection member is rotatably disposed on the wall surface of the sewage treatment chamber 111 .

[0104] It can be understood that the injection member can be rotatably arranged to increase the effective range of the injection member.

[0105] In one embodiment of the present application, the other end of the injection member is connected to the water pumping pipe 121, and the injection member is electrically connected to the control member, and the control member is configured to: based on the target position of the suspended carrier, control the opening and closing of different first electronic valves 113, the opening and closing of different second electronic valves 115, and the operation of the injection member.

[0106] It is understandable that the injection member can inject water into the water suction pipe 121, and then inject the water into a specific area of ​​the sewage treatment chamber 111 through the first pipe 112 and the second pipe 114, thereby achieving precise control of the suspended carrier in the sewage treatment chamber 111.

[0107] It is understandable that different first electronic valves 113 and different second electronic valves 115 divide the sewage treatment chamber 111 into multiple areas, and by controlling the opening and closing of the first electronic valve 113 and the second electronic valve 115 and the opening and closing sequence, the water sprayed by the spraying member is used to increase the density of the suspended carrier in the target area. For example, part of the suspended carrier in the area with better sewage treatment effect can be driven to the area with poor sewage treatment effect.

[0108] In one embodiment of the present application, the suspension carrier is connected to a plurality of travel motors, and the travel motors are electrically connected to the control component.

[0109] It can be understood that by controlling the operation of multiple travel motors, the suspended carrier can be controlled to move in a specified direction, and the position of the suspended carrier can be accurately controlled. When the travel motor is working, it will drive the sewage in the sewage treatment chamber 111 to flow, which is beneficial to improving the sewage treatment effect.

[0110] It is understandable that different travel motors are connected to different positions of the suspension carrier, so that the suspension carrier can be moved in a specified direction by controlling the different travel motors.

[0111] In one embodiment of the present application, the MBBR-based sewage treatment system further includes a cleaning tank, which is disposed adjacent to the sewage treatment tank 110 and is used to clean the suspended carrier.

[0112] It is understandable that the suspension carrier needs to be cleaned after a certain period of use to ensure the sewage treatment effect. In this embodiment, the cleaning tank is arranged adjacent to the sewage treatment chamber 111, so as to facilitate the movement of the suspension carrier into the sewage treatment tank 110 for cleaning.

[0113] In one embodiment of the present application, the MBBR-based sewage treatment system also includes a mounting frame, a rotating shaft, a rotating drive member and a plurality of automatic winding members. The mounting frame is arranged between the sewage treatment tank 110 and the cleaning tank. The rotating shaft is rotatably connected to the mounting frame. The rotating drive member is installed on the mounting frame and connected to the rotating shaft. The rotating drive member is used to drive the rotating shaft to rotate. The automatic winding member is connected to the rotating shaft. Each automatic winding member is connected to a suspended carrier via a connecting rope. The automatic winding member is used to wind or release the connecting rope.

[0114] It can be understood that the automatic winding member has two states, one is a winding state and a release state. In the winding state, the automatic winding member winds up the connecting rope so that the connecting rope is wound around the automatic winding member, and the suspended carrier is recovered. In the release state, the automatic winding member releases the connecting rope, and the suspended carrier can move freely. When in use, the rotating drive member drives the rotating shaft to rotate, and the automatic winding member rotates with it. When part of the automatic winding member rotates to one side of the cleaning tank, the part of the automatic winding member switches to the release state, and the suspended carrier can fall into the cleaning tank for cleaning. When the suspension carrier is cleaned, the rotating shaft rotates, and at the same time, the part of the automatic winding member switches to the winding state, and the suspended carrier is recovered, so that the suspended carrier can rotate to the sewage treatment tank 110. When it rotates to the sewage treatment tank 110, the automatic winding member is in the release state again, and the suspended carrier falls into the sewage treatment tank 110 to treat the sewage, realizing the automatic movement of the suspended carrier between the sewage treatment tank 110 and the cleaning tank.

[0115] It is understandable that the state of the automatic winding member can be controlled so that the suspended carrier falls into or leaves the sewage treatment tank 110, that is, the amount of the suspended carrier in the sewage treatment tank 110 can be adjusted.

[0116] In one embodiment of the present application, in order to further improve efficiency, the MBBR-based sewage treatment system may also include an online water quality monitoring system, and the first pipeline and the second pipeline are specifically used for gas transmission.

[0117] like Figure 6 , Figure 7 , Figure 8 and Fig. 9 As shown, the water quality online monitoring system includes:

[0118] An online water quality monitoring unit, used to obtain water quality monitoring data of a first type of parameter of a first sample to be tested and a second sample to be tested;

[0119] A first sampling component 7, used for sampling the water body in the first to-be-detected area 31 to form a first to-be-detected sample;

[0120] A second sampling component 8 is used to sample the water in the second to-be-tested area 32 to form a second to-be-tested sample;

[0121] A data processing unit, used for receiving the water quality monitoring data from the water quality online monitoring unit, and for performing a difference comparison between the water quality monitoring data of the first type of parameter of the first sample to be tested and the water quality monitoring data of the second sample to be tested to obtain a first difference value;

[0122] In the case that the first difference is outside the first threshold, the data processing unit performs a second feedback action, and the second feedback action includes: generating a second signal, and the second signal is suitable for providing early warning information.

[0123] It can be understood that this embodiment, as a carrier of the online water quality monitoring method involved in the first embodiment, can achieve the technical effect applied to the first embodiment. The water bodies at the first detection area 31 and the second detection area 32 are sampled respectively by the first sampling component 7 and the second sampling component 8 to form the first test sample and the second test sample respectively. The water quality monitoring data of the first type of parameter of the first test sample and the second test sample are obtained by the online water quality monitoring unit, and the data processing unit performs a difference comparison calculation to obtain the first difference. When the first difference is outside the first threshold, it means that the two detection areas in the same water body are quite different, and the water quality of the entire water body cannot be inferred by local sampling. At this time, whether it is the water quality monitoring data of the first test sample or the second test sample of this type of parameter, it cannot be used as a basis for directly judging whether the parameter of this type of parameter in the water body is up to standard. The data processing unit can perform other verification methods to increase the accuracy of water quality monitoring.

[0124] In one embodiment of the present application, it also includes

[0125] A monitoring data storage unit, the monitoring data storage unit is electrically connected to the data processing unit and is used to receive the water quality monitoring data, the first difference and the second signal sent from the data processing unit;

[0126] The human-computer interaction unit is electrically connected to the monitoring data storage unit, and is used to receive data information stored in the monitoring data storage unit, and to display the data signal on the display interface of the human-computer interaction unit. The data information includes water quality monitoring data, a first difference, and a second signal.

[0127] It can be understood that in this embodiment, the water quality monitoring data, the first difference and the second signal can be stored in the background through the monitoring data storage unit to achieve data traceability, and the display interface of the human-computer interaction unit can intuitively display the data information of the monitoring data storage unit for water quality monitoring personnel to observe or verify.

[0128] It can be understood that when the online water quality monitoring method used in this embodiment includes the second difference, the third difference, the first signal and other data signals related to water quality monitoring, the monitoring data storage unit and the human-computer interaction unit can both receive the first signal.

[0129] In a preferred embodiment, the human-computer interaction unit is also electrically connected to the data processing unit to implement the setting of parameters such as various thresholds involved in the data of the data processing unit.

[0130] In one embodiment of the present application, the data processing unit includes a data preprocessing module and a plurality of data difference modules, the data preprocessing module is used to identify different types of parameters of water quality monitoring data and place them in different first submodules, and at least one group of first submodules is used to receive water quality monitoring data of first type parameters;

[0131] The data difference module is electrically connected to the first submodule in a one-to-one correspondence. The data difference module is used to receive the water quality monitoring data of the connected first submodule, and to perform a difference comparison on the water quality monitoring data from the first sampling component 7 and the second sampling component 8 in the first submodule. At least one group of data difference modules is used to calculate the first difference.

[0132] Different types of parameters are classified through the data preprocessing module and transmitted to the corresponding data difference modules through the first submodule respectively. When the difference processing of water quality monitoring data involving two different types of parameters is carried out, the difference calculation can be carried out in parallel through different multiple data difference modules, thereby improving the data processing speed and avoiding the inefficient processing caused by the serial difference calculation method for only one type of parameter in a time period.

[0133] In one embodiment of the present application, the monitoring data storage unit includes a plurality of second submodules electrically connected to the first submodules in one-to-one correspondence, and the second submodules are used to store data information of the corresponding first submodules;

[0134] The human-computer interaction unit includes a plurality of interactive data channels electrically connected to the second submodules respectively, and the interactive data channels are used to transmit data information of the corresponding second submodules and display them in different display areas of the display interface.

[0135] It can be understood that in the present embodiment, different types of parameters can be stored respectively through the multiple second sub-modules of the monitoring data storage unit. Accordingly, if it is necessary to extract the water quality monitoring data of a specified type of parameter of the monitoring data storage unit through the human-computer interaction unit, the operation can be directly performed in the corresponding display area to send instructions to the corresponding second sub-module through the corresponding interactive data channel, so as to extract the water quality monitoring data in the local area in a targeted manner, and the data extraction of multiple types of parameters can be performed in parallel, thereby improving the processing efficiency.

[0136] In one embodiment of the present application, it also includes:

[0137] The support plate 5, the first sampling assembly 7 and the second sampling assembly 8 are arranged on the support plate 5, the first sampling assembly 7 and the second sampling assembly 8 are both provided with a feed port 2, the feed port 2 is adapted to be conducted when in contact with the water body 3, and closed when out of the water body 3, and the multiple feed ports 2 are respectively connected to the water quality online monitoring unit through different flow channels;

[0138] At least two crank-connecting rod mechanisms 4, including a first crank portion 41, a second crank portion 42 and a Y-shaped connecting rod 43, two ends of the Y-shaped connecting rod 43 are respectively hinged to the first crank portion 41 and one end of the second crank portion 42, and the remaining end of the Y-shaped connecting rod 43 is hinged to the support plate 5, and the length of the first crank portion 41 is different from that of the second crank portion 42;

[0139] The first rotating driving member has a driving end connected to the first crank part 41 or the second crank part 42 .

[0140] It can be understood that, in the present embodiment, the first crank portion 41 or the second crank portion 42 of one group of crank-connecting rod mechanisms 4 can be driven by the first rotating driving member, thereby driving the crank-connecting rod mechanism 4 to move, causing the Y-shaped connecting rod 43 to swing. Under the swinging action of the Y-shaped connecting rod 43 of the plurality of groups of crank two-rod mechanisms, the support plate 5 can move in an elliptical trajectory, and the surface orientation of the first sampling assembly 7 and the second sampling assembly 8 provided in the support plate 5 remains unchanged. With such movement, the first sampling assembly 7 and the second sampling assembly 8 can reciprocate in and out of the water body 3, and can sample the water body 3 when entering the water body 3, thereby avoiding the problem that the first sampling assembly 7 and the second sampling assembly 8 are always in contact with the water body 3, causing the impurities of the first sampling assembly 7 and the second sampling assembly 8 to penetrate into the water body 3 and cause pollution. At the same time, the first sampling assembly 7 and the second sampling assembly 8 can be driven to perform sampling actions simultaneously by only one group of rotating driving members, thereby simplifying the driving mode of the sampling device and ensuring the synchronization of the sampling actions of the first sampling assembly 7 and the second sampling assembly 8.

[0141] Specifically, refer to Figure 8-9, wherein the arrow without a number in the figure indicates the direction of water flow, the first sampling assembly 7 or the second sampling assembly 8 comprises a first sleeve member 71 and a second sleeve member 72 which are sleeved together, the feed inlet 2 is formed in the first sleeve member 71, the second sleeve member 72 is connected to the support plate 5, the second sleeve member 72 is provided with a ball valve 73 whose outer edge matches the inner edge of the feed inlet 2, the first sleeve member 71 is adapted to move toward one side of the second sleeve member 72 under the action of the resistance given by the water body 3 when moving toward the water body 3 and contacting the water body 3, so as to open the feed inlet 2 blocked by the ball valve 73.

[0142] It can be understood that the larger the contact area between the first sleeve member 71 and the water body 3, the greater the resistance effect, and the easier it is for the first sleeve member 71 to move toward the side of the second sleeve member 72. Specifically, a plate-shaped resistance increasing member 74 can be provided on the outer periphery of the first sleeve member 71 on the feed port 2 to increase the contact area between the first sleeve member 71 and the water body 3.

[0143] In one embodiment of the present application, the MBBR-based sewage treatment system further includes a water body accommodating space and a cyclone generating device, and the data processing unit is further used to perform a difference comparison between the water quality monitoring data of the second type parameter of the first sample to be tested and the second sample to be tested to obtain a fourth difference value, and the second type parameter includes a sediment concentration;

[0144] The vortex generating device is disposed in the water accommodating space and is adapted to: when the fourth difference is outside the fourth threshold, stir the water to form a vortex covering the first to-be-detected area 31 and the second to-be-detected area 32 .

[0145] It can be understood that in this embodiment, the sediments in different areas will have an adhesion effect on other types of parameter materials. By stirring the water body to form a vortex covering the first area to be detected 31 and the second area to be detected 32, the sediments in the monitored water body can be homogenized, thereby making the water quality monitoring data of each type of parameter tend to be consistent, thereby ensuring the accuracy of the monitoring results.

[0146] Specifically, the vortex generating device may include a second rotating driving member, and the driving end of the second rotating driving member is connected to a stirring blade, and the vortex is formed by the second rotating driving member driving the stirring blade. It can also be a cyclone device, which drives the water body to flow by outputting gas in the vortex flow direction, thereby forming a vortex.

[0147] When using the above-mentioned online water quality monitoring system, you can refer to the following operations:

[0148] The first sampling assembly 7 is used to sample the water in the first to-be-detected area 31 to form a first to-be-detected sample;

[0149] The second sampling assembly 8 is used to sample the water in the second to-be-detected area 32 to form a second to-be-detected sample.

[0150] The water quality monitoring data of the first type of parameter of the first sample to be tested and the second sample to be tested are obtained, and a difference comparison is performed to obtain a first difference value.

[0151] Step 103, when the first difference is outside the first threshold, performing a second feedback action, the second feedback action includes: generating a second signal, the second signal is suitable for providing early warning information.

[0152] It should be noted that the first to-be-detected area 31 and the second to-be-detected area 32 are configured as two areas in a water body accommodating space that are connected and have different spatial positions.

[0153] The above-mentioned actions of sampling the water body of the first area to be detected 31 by using the first sampling component 7 and sampling the water body of the second area to be detected 32 by using the second sampling component 8 are performed simultaneously. In actual situations, a small time interval that is close to being performed simultaneously should also be regarded as being performed simultaneously. The small time interval can be defined as a time interval in which the water quality monitoring data will not substantially change before and after the time interval under normal circumstances. Referring to the current "Pollutant Discharge Standard for Urban Sewage Treatment Plants" (GB 18918-2002) "3.1.4 Sampling and Monitoring" section stipulates: "4.1.4.2 The sampling frequency is at least once every 2 hours, and a 24-hour mixed sample is taken, calculated as the daily average value". In this embodiment, in order to ensure the monitoring accuracy, the small time interval can be preferably within 2 hours, that is, the two sampling actions should be regarded as being performed simultaneously within 2 hours.

[0154] The online water quality monitoring method of the embodiment of the present application samples water at two locations, a first area to be detected 31 and a second area to be detected 32, respectively, to form a first sample to be tested and a second sample to be tested, respectively, and obtains water quality monitoring data of a first type of parameter of the first sample to be tested and the second sample to be tested by manually using conventional instruments or automated monitoring equipment, and performs a difference comparison calculation to obtain a first difference. When the first difference is outside the first threshold, it means that the two areas to be detected in the same water body are quite different, and the water quality of the entire water body cannot be inferred by local sampling. At this time, whether it is the water quality monitoring data of this type of parameter of the first sample to be tested or the second sample to be tested, it cannot be used as a basis for directly judging whether the parameter of this type of parameter of the water body is up to standard. It is necessary to provide an early warning signal to remind the water quality monitor or send an instruction to the downstream data processing unit for verification in other ways, thereby increasing the accuracy of water quality monitoring.

[0155] Specifically, other verification methods may be to add additional monitoring areas, divide the same horizontal plane of the monitored water body into multiple monitoring areas in an equal-proportion matrix, conduct multi-point monitoring to determine the distribution of this type of parameters at different locations, and then carry out targeted treatment of locations in the water body containing unqualified parameters.

[0156] The first type of parameter may be one of various types of parameters such as water temperature, chromaticity, turbidity, pH value, conductivity, suspended solids, dissolved oxygen, chemical oxygen demand, biochemical oxygen demand, phenol, cyanide, arsenic, lead, chromium, cadmium, mercury and organic pesticides, which are used to determine whether the water quality is qualified. If it is necessary to monitor the pH parameter, the first type of parameter is the pH value. It can be understood that obtaining the above-mentioned parameters from the sample to be tested is a skill that can be mastered by those skilled in the art, so the detailed method of how to obtain the above-mentioned parameters from the sample to be tested will not be repeated.

[0157] The above calculation method for difference comparison is also a skill that can be mastered by those skilled in the art. For example, if the pH value of the first sample to be tested is 7 and the pH value of the second sample to be tested is 5, then the first difference is 2.

[0158] It can be understood that the first threshold value can be defined as a numerical range in which, based on the water quality monitoring data of the first type of parameter of the first sample to be tested, a numerical value outside the first threshold value (the numerical value is regarded as a real number, not an absolute value) is added, which will cause a change in the result of whether the water quality monitoring data meets the requirements. Because the numerical value is regarded as a real number, not an absolute value, when the positive and negative signs of the first threshold value are different, it should also be regarded that the first threshold value can be a combination of multiple numerical ranges at the same time. For example, if the water quality pH value standard range is 6.5 to 8.5, and the pH value of the first sample to be tested is 7, the pH value of the second sample to be tested is 7.5. When the pH value is 5, and 7 is outside the standard range, the first threshold can be considered to include two, namely ≤0.5 (i.e. 7-6.5) and ≥-1.5 (i.e. 7-8.5). The first difference (7-5=2 in this embodiment) is outside the range, and the second sample to be tested is within the standard range of water quality pH value, which leads to inconsistent verification results of the first sample to be tested and the second sample to be tested. In other words, the first difference 2 formed by the difference of the same type of parameters of the first sample to be tested and the second sample to be tested is outside the first threshold (≤0.5 or ≥-1.5), and a second signal needs to be generated.

[0159] Exemplarily, the threshold value may also be understood by those skilled in the art, and although it is not sufficient to cause a change in the result of whether the water quality monitoring data meets the requirements, it is a difference size that will not be produced under normal circumstances.

[0160] It is understandable that when the first difference is within the first threshold, it is a normal situation and usually no additional feedback action is required. Exemplarily, a first feedback action is also performed, and the first feedback action includes: generating a first signal, and the first signal can be any signal used to inform that there is no abnormality in the monitoring situation.

[0161] In one embodiment of the present application, it also includes:

[0162] The first sampling component 7 is used to sample the water in the third to-be-tested area 33 to form a third to-be-tested sample;

[0163] The water body of the fourth to-be-detected area 34 is sampled by the second sampling assembly 8 to form a fourth to-be-detected sample, the first to-be-detected area 31 and the third to-be-detected area 33 are configured as two interconnected areas in a water body accommodating space, located at the same height and at different horizontal positions, the second to-be-detected area 32 and the fourth to-be-detected area 34 are configured as two interconnected areas in a water body accommodating space, located at the same height and at different horizontal positions, and the first to-be-detected area 31 and the second to-be-detected area 32 are located at different heights;

[0164] The first sample to be tested, the second sample to be tested, the third sample to be tested and the fourth sample to be tested are stored.

[0165] It can be understood that the steps of this embodiment may be:

[0166] The first sampling assembly 7 is used to sample the water in the first to-be-detected area 31 to form a first to-be-detected sample, and the water in the third to-be-detected area 33 is sampled to form a third to-be-detected sample;

[0167] The second sampling assembly 8 is used to sample the water in the second area to be detected 32 to form a second sample to be detected, and the water in the fourth area to be detected 34 is sampled to form a fourth sample to be detected.

[0168] The water quality monitoring data of the first type of parameter of the first sample to be tested and the second sample to be tested are obtained, and a difference comparison is performed to obtain a first difference value.

[0169] When the first difference is outside the first threshold, a second feedback action is performed, the second feedback action includes: generating a second signal, and the second signal is suitable for providing early warning information.

[0170] The first sample to be tested, the second sample to be tested, the third sample to be tested and the fourth sample to be tested are stored.

[0171] It should be noted that, in this embodiment, step 104 may also be placed before step 102 .

[0172] In this embodiment, not only is the water sampled at different positions of the same horizontal plane in the area to be detected, but multi-point sampling is also performed at different heights in the same vertical direction, thereby further broadening the scope of the monitoring data and improving the accuracy.

[0173] For example, under normal circumstances, there are more sediments in the low position of the water body. When monitoring the sediment concentration type parameter, if the sediment concentration of the first sample to be tested is lower than the sediment concentration of the third sample to be tested, it means that there are more sediments in the low position of the water body. If the type parameters other than the sediment concentration are obtained at this time, and there is a difference in the water quality monitoring data of this type of parameter between the third sample to be tested and the first sample to be tested, it means that this type of parameter may be dependent on the sediment. Therefore, it can provide a research basis and broaden the analysis dimension of water quality monitoring.

[0174] In one embodiment of the present application, it also includes:

[0175] Obtaining water quality monitoring data of the first type of parameter of the first sample to be tested and the third sample to be tested, and performing difference comparison to obtain a second difference value;

[0176] and / or

[0177] Acquire water quality monitoring data of the first type of parameter of the second sample to be tested and the fourth sample to be tested, and transmit the data to the comparison unit for difference comparison to obtain a third difference value;

[0178] When the second difference is outside the second threshold, performing a third feedback action, the third feedback action comprising: generating a third signal;

[0179] When the third difference is outside the third threshold, a fourth feedback action is performed, and the fourth feedback action includes: generating a fourth signal, and both the third signal and the fourth signal are suitable for providing early warning information.

[0180] It can be understood that, in this embodiment, the steps are:

[0181] The first sampling assembly 7 is used to sample the water in the first to-be-detected area 31 to form a first to-be-detected sample, and the water in the third to-be-detected area 33 is sampled to form a third to-be-detected sample;

[0182] The second sampling assembly 8 is used to sample the water in the second area to be detected 32 to form a second sample to be detected, and the water in the fourth area to be detected 34 is sampled to form a fourth sample to be detected.

[0183] The water quality monitoring data of the first type of parameter of the first sample to be tested and the second sample to be tested are obtained, and a difference comparison is performed to obtain a first difference value.

[0184] When the first difference is outside the first threshold, a second feedback action is performed, the second feedback action includes: generating a second signal, and the second signal is suitable for providing early warning information.

[0185] The first sample to be tested, the second sample to be tested, the third sample to be tested and the fourth sample to be tested are stored.

[0186] Obtaining water quality monitoring data of the first type of parameter of the first sample to be tested and the third sample to be tested, and performing difference comparison to obtain a second difference value;

[0187] and / or

[0188] Acquire water quality monitoring data of the first type of parameter of the second sample to be tested and the fourth sample to be tested, and transmit the data to the comparison unit for difference comparison to obtain a third difference value;

[0189] In the case where the second difference is outside the second threshold, performing a third feedback action, the third feedback action comprising: generating a third signal suitable for providing early warning information;

[0190] When the third difference is outside the third threshold, a fourth feedback action is performed, and the fourth feedback action includes: generating a fourth signal suitable for providing early warning information.

[0191] It can be understood that in this embodiment, not only is sampling performed on the water bodies in the detection area at different positions of the same horizontal plane (such as the first sample to be tested and the second sample to be tested, or the third sample to be tested and the fourth sample to be tested), but multi-point sampling is also performed at different heights in the same vertical direction, thereby further broadening the scope of the monitoring data and improving the accuracy. In addition, the water quality monitoring data of the same type of parameters of two samples to be tested (such as the first sample to be tested and the third sample to be tested, or the second sample to be tested and the fourth sample to be tested) at different heights in the same numerical direction are differentially compared, thereby expanding the basis dimension for verifying the monitoring results and improving the monitoring accuracy. For specific differential comparisons, please refer to the aforementioned embodiments, and the definitions of the second threshold value and the third threshold value may refer to the description of the definition of the first threshold value in the aforementioned embodiments, which will not be repeated here.

[0192] In one embodiment of the present application, the second feedback action further includes:

[0193] After the second signal is generated and after a preset period of time:

[0194] The first sampling assembly 7 is used to sample the water in the first to-be-tested area 31 to form a fifth to-be-tested sample;

[0195] The water in the second to-be-tested area 32 is sampled by using the second sampling assembly 8 to form a sixth to-be-tested sample;

[0196] Obtain water quality monitoring data of the first type of parameter of the fifth sample to be tested and the sixth sample to be tested, and perform a difference comparison to obtain a fifth difference value

[0197] When the fifth difference is within the first threshold, performing a first feedback action;

[0198] When the fifth difference is outside the first threshold, a second feedback action is performed, the second feedback action includes: generating a second signal, and the second signal is suitable for providing early warning information.

[0199] It can be understood that the steps of this embodiment can be

[0200] The first sampling assembly 7 is used to sample the water in the first to-be-detected area 31 to form a first to-be-detected sample;

[0201] The second sampling assembly 8 is used to sample the water in the second to-be-detected area 32 to form a second to-be-detected sample.

[0202] The water quality monitoring data of the first type of parameter of the first sample to be tested and the second sample to be tested are obtained, and a difference comparison is performed to obtain a first difference value.

[0203] When the first difference is outside the first threshold, a second feedback action is performed, the second feedback action includes: generating a second signal, and the second signal is suitable for providing early warning information.

[0204] After the second signal is generated and after a preset period of time:

[0205] The first sampling assembly 7 is used to sample the water in the first to-be-tested area 31 to form a fifth to-be-tested sample;

[0206] The water in the second to-be-tested area 32 is sampled by using the second sampling assembly 8 to form a sixth to-be-tested sample;

[0207] Obtaining water quality monitoring data of the first type of parameter of the fifth sample to be tested and the sixth sample to be tested, and performing difference comparison to obtain a fifth difference value;

[0208] When the fifth difference is outside the first threshold, a second feedback action is performed, the second feedback action includes: generating a second signal, and the second signal is suitable for providing early warning information.

[0209] It can be understood that after the second signal is generated, if after a certain preset time interval, the fifth difference returns to the first threshold, the difference of the first type of parameter water quality monitoring data monitored in different areas to be detected returns to the normal difference range, and the corresponding action of the early warning signal can be canceled. If it still remains outside the first threshold, it means that it is still in an abnormal state, and it is necessary to continue to provide early warning signals to remind water quality monitors or send instructions to the downstream data processing unit for other verification methods, thereby increasing the accuracy of water quality monitoring.

[0210] Specifically, other verification methods may be to add additional monitoring areas in the aforementioned embodiments, divide the same horizontal plane of the monitored water body into multiple monitoring areas in an equal proportion matrix, conduct multi-point monitoring to determine the distribution of this type of parameters at different locations, and then carry out targeted processing of the locations where the water body contains unqualified parameters.

[0211] It can be understood that when the fifth difference is within the first threshold, it is a normal situation and usually no additional feedback action is required. Exemplarily, a first feedback action can also be performed, and the first feedback action includes: generating a first signal, and the first signal can be any signal used to inform that there is no abnormality in the monitoring situation.
