Description

Technical Field

[0001] The present disclosure generally relates to the field of water treatment technology. More specifically, the present disclosure relates to a sewage treatment method, system and related products for a working pool. Background Art

[0002] Water treatment technology is a series of methods and processes for treating water to achieve the required water quality standards. Adding chemicals in the flocculation sedimentation tank is an important part of the water treatment process. The main purpose of adding chemicals is to make the suspended particles in the water form larger flocs through coagulation and flocculation, so as to facilitate precipitation and separation. In raw water, suspended particles usually have the same charge, repel each other, and are in a stable dispersed state. By adding chemicals, the charge properties of the particle surface are changed, so that they can attract each other and combine together to form larger floc particles, thereby accelerating the precipitation speed and improving the water purification effect.

[0003] In the process of adding drugs in the flocculation sedimentation tank, the relevant flocculation sedimentation tank dosing is generally manually adjusted according to the influent water quality, and the flocculation dosing water output is manually judged. However, when the water quality suddenly changes, the dosage cannot be adjusted in time, which will cause the back-end water equipment to be blocked and damaged, affecting the safety of water quality. In addition, abnormal water quality mutations cannot be warned in time, and emergency work is delayed, which will increase the difficulty of water purification. Furthermore, manually adjusting the dosing metering of the flocculation sedimentation tank has higher technical requirements, greater operation difficulty, and longer adjustment time.

[0004] In view of this, there is an urgent need to provide a sewage treatment method, system and related products for a working water tank, so as to ensure the quality of the effluent water from the flocculation sedimentation tank. Summary of the invention

[0028] The specific implementation of the present disclosure is described in detail below with reference to the accompanying drawings.

[0029] Figure 1 FIG. 1 shows an exemplary flow chart of a sewage treatment method 100 for a pool according to some embodiments of the present disclosure. Figure 1As shown, the working water tank includes an inlet end and an output end, and the method includes: S101 obtaining data of the sewage at the inlet end as first data; S102 calculating an initial dosage based on the first data, wherein the initial dosage is determined as a current dosage; S103 adding a first additive to the sewage based on the current dosage to treat the sewage; S104 obtaining data of the treated sewage at the output end as second data; S105 correcting the current dosage based on the second data to add the first additive in the next cycle.

[0030] In some embodiments, the aforementioned working water pool may include a flocculation sedimentation tank, in which a flocculant may be added. In the flocculation sedimentation tank, the sewage may first be mixed with the flocculant to aggregate the suspended matter and colloidal substances in the water into larger particles, which then settle to the bottom of the tank by sedimentation.

[0031] In some embodiments, the inlet end of the flocculation sedimentation tank can be connected to a raw water tank, wherein the raw water tank can be used to collect and store untreated sewage (such as domestic sewage, industrial wastewater, etc.). The raw water tank and the flocculation sedimentation tank can be connected by pipeline connection, channel connection or special connection.

[0032] Specifically, the raw water tank and the flocculation sedimentation tank can be connected by a pipeline. When the raw water tank is located higher than the flocculation sedimentation tank, the water level difference can be used to allow the raw water to flow into the flocculation sedimentation tank through the pipeline by gravity. An outlet pipe can be installed at the outlet end of the raw water tank, and the pipeline is connected to the water inlet of the flocculation sedimentation tank. The flow rate and flow velocity of the raw water can be controlled by adjusting the valve on the pipeline. The sewage is transferred by gravity, which has low energy consumption and stable operation. If the relative position of the raw water tank and the flocculation sedimentation tank is not conducive to gravity flow, or the raw water needs to be pressurized to meet the requirements of the subsequent treatment process, a water pump can be installed at the edge of the raw water tank to pressurize the raw water and transport it to the flocculation sedimentation tank.

[0033] Furthermore, the raw water tank and the flocculation sedimentation tank can be connected through a channel. An open channel can be built between the raw water tank and the flocculation sedimentation tank, and the sewage can flow into the flocculation sedimentation tank through the open channel. The raw water tank and the flocculation sedimentation tank can also be connected through a dark channel, so that the sewage can flow in a closed dark channel, which can avoid external interference and make the water quality more stable.

[0034] Furthermore, the raw water tank and the flocculation sedimentation tank can be connected through a wall hole or through a diversion and water distribution device. When connected through a wall hole, a number of evenly distributed perforations can be set on the partition wall between the raw water tank and the flocculation sedimentation tank, and the raw water flows from the raw water tank into the flocculation sedimentation tank through these perforations. The size, number and distribution of the perforations are designed according to factors such as the raw water flow rate and water quality, so that the raw water can enter the flocculation sedimentation tank evenly, promoting the uniform flocculation reaction. When connected through a diversion and water distribution device, a diversion and water distribution device such as a guide plate and a water distributor can be set between the raw water tank and the flocculation sedimentation tank. The raw water can first enter the diversion and water distribution device, and then enter the flocculation sedimentation tank after being evenly distributed. This connection method can effectively control the direction and flow rate of the water flow, so that the raw water is evenly distributed in the flocculation sedimentation tank, and improve the flocculation sedimentation effect.

[0035] In some embodiments, obtaining the data of the sewage at the entry end may include obtaining the data of the sewage in the raw water tank. In other embodiments, obtaining the data of the sewage at the entry end may also include obtaining the data of the sewage in the pipe or channel between the raw water tank and the flocculation sedimentation tank.

[0036] Preferably, data of the pipeline between the raw water tank and the flocculation sedimentation tank for sewage can be obtained. Specifically, the inlet end of the aforementioned water tank may include a first pipeline, wherein the first pipeline may be a pipeline connecting the raw water tank and the flocculation sedimentation tank. It should be understood that the aforementioned first data may include the turbidity value of the sewage. The turbidity of sewage can be used to measure the number of suspended particles in the water, indicating the degree of turbidity of the water, wherein the suspended particles in the water may include silt, clay, organic matter, microorganisms and other insoluble substances.

[0037] In some embodiments, the turbidity of the water can be determined by comparing the sewage to be tested with a series of standard solutions of known turbidity through human visual observation. Furthermore, the turbidity of the sewage can also be detected by spectrophotometry or gravimetry. Preferably, a turbidity meter can be selected to directly measure the turbidity of the sewage, which is convenient to carry, simple to operate, and can quickly obtain measurement results, so that the turbidity of the sewage can be fed back in time.

[0038] In some embodiments, a first turbidity meter may be provided in the first pipe at the input end, so as to measure the turbidity value of the sewage in the first pipe. It is understandable that the turbidity value measured by the first turbidity meter may be the turbidity value in the first data.

[0039] In some embodiments, the first additive may include a coagulant, such as aluminum sulfate, ferric chloride and / or polyaluminium chloride (PAC). Preferably, PAC can be selected, which can undergo a hydrolysis reaction in water to generate aluminum hydroxide colloid. These colloids carry a positive charge and can neutralize the negative charge on the surface of suspended particles in water, reducing the electrostatic repulsion between particles. At the same time, aluminum hydroxide colloid can also further aggregate the condensed particles to form larger flocs through adsorption bridging, which is convenient for precipitation and removal. When the turbidity of sewage changes, by putting PAC into sewage, PAC can cause the sediment particles to condense into larger flocs in a short time, accelerate the sedimentation rate, and facilitate timely adjustment. Further, in addition to removing suspended particles in water and reducing turbidity, PAC can also adsorb some organic matter, heavy metal ions and microorganisms in water. Furthermore, PAC can maintain a good coagulation effect in a wide pH range and has a wider range of uses.

[0040] In some embodiments, when the first additive is added to the sewage, the initial addition amount can be calculated according to the turbidity value in the first data, wherein the initial addition amount can include the initial dosage of the first additive, the initial frequency of the first additive and the initial flow rate of the first additive. Specifically, the initial dosage of the first additive can be obtained according to the following formula:

[0041] y 1 =k 1 x 1 +b 1

[0042] Among them, y 1 It can be the initial dose of the first additive, k 1 can be the first turbidity coefficient, x 1 can be the turbidity value in the first data, b 1 In some embodiments, the first turbidity coefficient k 1 can be 0.113, the second turbidity coefficient b 1 It can be 10.

[0043] In some embodiments, after obtaining the initial dosage of the first additive, the initial flow rate of the first additive can be obtained by combining the flow rate of the influent water and the concentration of the first additive. Specifically, the initial flow rate of the first additive can be obtained according to the following formula:

[0044]

[0045] Among them, y 2 can be the initial flow rate of the first additive, y 1 It can be the initial dose of the first additive, k2 can be the water inlet flow rate, b 2 can be the first flow coefficient, b 3 It can be the ratio concentration of the first additive. In some embodiments, the aforementioned water inlet flow rate k 2 Can be 40m 3 / h, the first flow coefficient b 2 can be 1000, the ratio concentration of the first additive b 3 It can be 0.05.

[0046] In some embodiments, after obtaining the initial flow rate of the first additive, the frequency of dosing can be obtained in combination with the flow rate of the PAC dosing pump. Specifically, the frequency of the first additive can be obtained according to the following formula:

[0047]

[0048] Among them, f 1 can be the initial frequency of the first additive, y 2 can be the initial flow rate of the first additive, k 3 Can be the flow rate of PAC dosing pump, b 4 In some embodiments, the flow rate k of the PAC dosing pump is 3 It can be 25L / h, the second flow coefficient b 4 It can be 50.

[0049] After obtaining the initial dosage of the first additive, the initial flow rate of the first additive, and the initial frequency of the first additive, the first additive can be added into the aforementioned first pipeline. Specifically, a PAC dosing device, such as a PAC dosing pump, can be provided at the entrance end of the aforementioned water pool, wherein the aforementioned PAC dosing pump can include a variable frequency dosing pump. The aforementioned variable frequency dosing pump can change the frequency of the power supply, thereby changing the speed of the motor of the dosing pump, and then changing the stroke speed and the discharge frequency of the dosing pump, thereby enabling the adjustment of the PAC flow rate output by the dosing pump. In some embodiments, the aforementioned PAC dosing pump can be connected to the first pipeline, so that PAC can be added to the first pipeline, thereby achieving the delivery of PAC.

[0050] In some embodiments, sewage data can be obtained at the output end as the second data. Specifically, the output end of the treatment water tank can be connected to the intermediate water tank. It should be understood that the intermediate water tank can be used to temporarily store the effluent of the flocculation sedimentation tank to balance the inlet flow and water quality of the subsequent treatment unit. Because the effluent flow of the flocculation sedimentation tank may fluctuate due to factors such as changes in raw water quality and adjustments to the treatment process, the intermediate water tank can stabilize the flow to a certain extent to ensure that the subsequent treatment equipment (such as filtration equipment, deep treatment equipment) can operate under stable inlet conditions. The aforementioned flocculation sedimentation tank and the intermediate water tank can also be connected by a water pipe or by a channel. In some embodiments, a second turbidity meter can be used on the water pipe or channel between the aforementioned flocculation sedimentation tank and the intermediate water tank. It can be understood that the turbidity value measured by the aforementioned second turbidity meter can be the turbidity value at the output end, that is, the turbidity value in the second data.

[0051] In some embodiments, based on the aforementioned second data, the current dosage is corrected to perform dosage of the first additive in the next cycle. It is understandable that the first additive can be dosed in the flocculation sedimentation tank, or it can be dosed at the entry end. Preferably, the first additive can be dosed in the pipeline at the entry end. Specifically, a PAC dosing device can be provided at the entry end of the aforementioned water pool. It is understandable that one or more PAC dosing devices can be provided at the entry end of the aforementioned water pool. When multiple PAC dosing devices are provided at the entry end of the water pool, at least one PAC dosing device can be electrically connected to the first turbidity meter, and at least one PAC dosing device can be electrically connected to the second turbidity meter. When a PAC dosing device is provided at the entry end of the water pool, the aforementioned first turbidity meter and the second turbidity meter can both be electrically connected to the PAC dosing device.

[0052] Correcting the current dosage may include adding the first additive to the sewage based on the turbidity value of the second data. Figure 2 It is explained in detail how to correct the current dosage to obtain the actual dosage, the actual frequency of the first additive and the actual flow rate of the first additive.

[0053] It should be understood that after the actual dosage of the first additive is added to the sewage, the second turbidity meter can continue to detect the sewage in the second pipe. When the turbidity value of the sewage in the second pipe is not within the preset range, the actual dosage y 3 Can continue to correct (for example, with the actual increase coefficient k 4 The actual dosage can be kept unchanged until the turbidity value of the sewage in the second pipeline is within the preset range.

[0054] Through the scheme disclosed herein, the dosage of the added medicine can be adjusted in time according to the change of water quality, so as to maintain the stability of the effluent water quality and ensure the safety of the water quality. Furthermore, the scheme disclosed herein can stop adding medicine to the flocculation sedimentation tank when the water quality meets the standard, which can save the amount of added medicine and thus save costs.

[0055] Figure 2 An exemplary flow chart of a method 200 for modifying the current delivery amount in some embodiments of the present disclosure is shown. Figure 2 As shown, the method includes: comparing whether the second data meets the preset conditions to obtain a comparison result; in response to the second data not meeting the preset conditions, correcting the initial dosage to obtain a corrected initial dosage; using the corrected initial dosage as the current dosage to perform dosage of the first additive in the next cycle.

[0056] In some embodiments, in response to the second data not satisfying a preset condition, correcting the initial dosage includes: calculating a corrected dosage of the initial dosage based on the turbidity value of the second data, correcting the addition frequency and correcting the addition flow rate.

[0057] In some embodiments, the aforementioned preset condition may include whether the turbidity value is less than a preset turbidity value (e.g., 5NTU). When the turbidity value in the second data is not less than the preset turbidity value, the aforementioned initial dosage may be corrected. Specifically, the first additive correction dosage may be obtained according to the following formula:

[0058] y 11 =k 4 y 1

[0059] Among them, y 11 The dosage of the first additive can be corrected, y 1 It can be the initial dose of the first additive, k 4 In some embodiments, the aforementioned correction increase coefficient may be 1.05. 11 After that, the first additive correction flow rate can be obtained by combining the flow rate of the influent water and the concentration of the first additive. Specifically, the first additive correction flow rate can be obtained according to the following formula:

[0060]

[0061] Among them, y 21 The flow rate can be corrected for the first additive, y 11 The dosage of the first additive can be corrected, k 2 can be the water inlet flow rate, b 2 can be the first flow coefficient, b 3It can be the ratio concentration of the first additive. In some embodiments, the aforementioned water inlet flow rate k 2 Can be 40m 3 / h, the first flow coefficient b 2 can be 1000, the ratio concentration of the first additive b 3 It can be 0.05.

[0062] Furthermore, the first additive correction frequency can be obtained by the following formula:

[0063] f 2 =f 1 +5

[0064] Among them, f 2 can be the actual delivery frequency of PAC, f 1 It can be the frequency of the first additive.

[0065] By adjusting the amount of PAC added at the inlet end according to the turbidity value of the sewage at the discharge end, when the water quality at the input end changes, the amount of PAC added at the input end can be adjusted according to the turbidity value of the sewage at the discharge end, thereby maintaining the stability of the effluent quality and ensuring the safety of the water quality. Furthermore, when the turbidity value of the sewage at the discharge end meets the standard, the addition of drugs to the flocculation sedimentation tank can be stopped, which can save the amount of drugs added and thus save costs.

[0066] Figure 3 FIG. 3 is an exemplary flow chart of a sewage treatment method 300 for a pool according to some other embodiments of the present disclosure. Figure 3 As shown, the method further includes: S301 acquiring data of the sewage at the inlet end as third data; S302 adding a second additive to the sewage based on the third data; wherein the third data is different from the first data.

[0067] In some embodiments, the third data may include the pH value of the sewage, which may be obtained by installing a pH detector in the first pipe. It is understandable that the first data may include the turbidity value of the sewage, and the first data is different from the third data.

[0068] In some embodiments, the input end of the aforementioned water pool may be provided with a pH detector, which can be used to detect the acidity and alkalinity of the sewage at the input end. In some embodiments, the input end of the water pool may also be provided with an alkaline dosing device, such as a NaOH dosing device. It is understandable that the aforementioned NaOH dosing device may also include a NaOH variable frequency dosing pump. The aforementioned NaOH variable frequency dosing pump can adjust the stroke speed and discharge frequency of its dosing pump, thereby being able to achieve the adjustment of the NaOH flow rate output by the dosing pump. Furthermore, the aforementioned NaOH variable frequency dosing pump can be connected to the first pipeline, so that NaOH can be added to the first pipeline, thereby achieving the delivery of NaOH.

[0069] When the pH detector detects that the pH value of the sewage at the input end is not within the second preset interval, the NaOH variable frequency dosing pump can add NaOH agent to the first pipe, and the pH detector can detect the first pipe added with NaOH agent again, and the above process can be repeated. It can be understood that when the pH detector detects that the pH value of the sewage at the input end is within the second preset interval, the NaOH variable frequency dosing pump can stop adding NaOH agent to the first pipe.

[0070] It should be understood that the connection point between the NaOH variable frequency dosing pump and the first pipeline can be the first connection point, and the connection point between the pH detector and the first pipeline can be the second connection point. The aforementioned second connection point can be located between the first connection point and the connection point between the pipeline and the flocculation sedimentation tank, that is, along the direction from the raw water tank to the flocculation sedimentation tank along the pipeline, when the aforementioned sewage flows through the first pipeline, it can first be connected to the NaOH variable frequency dosing pump through the first connection point, and then connected to the pH detector through the second connection point.

[0071] In some embodiments, the amount of NaOH added can be determined based on the amount of PAC added and the ratio of NaOH to PAC dosage. Specifically, it can be determined according to the following formula:

[0072] y Na =k Na y 1

[0073] Among them, k Na Can be the ratio of NaOH to PAC dosage, y 1 It may be the dosage of the first additive.

[0074] By setting the positions of the aforementioned NaOH variable frequency dosing pump and the pH detector, the NaOH variable frequency dosing pump can decide whether to add NaOH to the sewage according to the pH detected by the pH detector, thereby adjusting the pH of the sewage.

[0075] In some embodiments, the method further includes: based on the current dosage, adding a third additive to the sewage; wherein a third dosage of the third additive is 1 / 25-1 / 20 of the current dosage.

[0076] In some embodiments, the third additive may include polyacrylamide (PAM), wherein after PAM is dissolved in water, the viscosity of its aqueous solution is relatively high, and it can combine with fine sediment and colloidal impurities in sewage and aggregate them into clumps, thereby reducing the concentration of sewage.

[0077] In some embodiments, the input end of the water pool may also be provided with a PAM dosing device. Specifically, the output end of the aforementioned PAM dosing device may be connected to the second pipeline, and after obtaining the dosage of the first additive, the dosage of the third additive may be obtained according to the dosage of the first additive, wherein the dosage of the aforementioned third additive may be 1 / 25-1 / 20 of the dosage of the first additive.

[0078] By setting the aforementioned third additive, the fine sediment and colloidal impurities in the sewage can be reduced, thereby reducing the turbidity in the sewage.

[0079] Figure 4 An exemplary flow chart of a method for adding a second additive to the sewage based on the third data according to some embodiments of the present disclosure is shown, as shown in FIG. Figure 4 As shown, the method includes: S401, based on the third data, determining whether the pH value of the third data is within a preset range; S402, in response to the pH value being within the preset range, stopping adding the third additive; S403, in response to the pH value being outside the preset range, adding the third additive.

[0080] In some embodiments, in the first pipeline along the direction from the raw water tank to the flocculation sedimentation tank, the sewage in the first pipeline may first pass through the connection point between the NaOH dosing device and the first pipeline, and then pass through the connection point between the pH detector and the first pipeline.

[0081] In some embodiments, the aforementioned third data may include the pH value of the sewage, which can be measured according to the pH detector in the aforementioned first pipe. The aforementioned preset interval may be 7.5-8.5. When the pH value of the aforementioned sewage is not within the aforementioned preset interval (for example, the pH value of the sewage is less than 7.5), the aforementioned NaOH dosing device may start the dosing operation to increase the pH value of the sewage. It is understandable that after the NaOH dosing device performs the dosing operation on the sewage, the pH detector may detect whether the pH value of the sewage after dosing is within the aforementioned preset interval. When it is within the preset interval, the aforementioned NaOH dosing device may stop the dosing operation; when the pH value of the sewage after dosing is not within the aforementioned preset interval, the NaOH dosing device may stop the dosing operation.

[0082] Through the above-mentioned settings, the solution disclosed in the present invention can determine whether it is necessary to add NaOH to the sewage according to the pH detected by the pH detector, thereby adjusting the pH of the sewage.

[0083] In some embodiments, a third addition flow rate and a third addition frequency of the third additive can be calculated based on the third addition amount of the third additive; after obtaining the third addition flow rate and the third addition frequency, the third additive can be added to the sewage.

[0084] Figure 5 An exemplary block diagram of a sewage treatment system for a working pool according to some embodiments of the present disclosure is shown. Figure 5 As shown, the working water tank includes an inlet end and an output end, and the system includes a first detection device, a second detection device, a first delivery device, a calculation device and a correction device; wherein the first detection device is connected to the inlet end, and is used to obtain the data of the sewage at the inlet end as the first data; the calculation device is electrically connected to the first detection device, and is used to calculate the initial delivery amount; the first delivery device is connected to the inlet end, and is used to deliver a first additive to the sewage; the second detection device is connected to the output end, and is used to obtain the data of the treated sewage at the output end as the second data; the correction device is electrically connected to the first delivery device and the second detection device, and is used to correct the current delivery amount.

[0085] In some embodiments, the inlet end of the working water tank may include a first pipe, which may be connected to the raw water tank and the flocculation sedimentation tank.
