In addition, some aspects disclosed by the utility model can be used alone, or in any appropriate combination with other aspects disclosed by the utility model.

[0048] Combination Figure 1-3 As shown in the example, the integrated skid-mounted sewage treatment control system 100 disclosed in the utility model includes a raw water storage tank 110, a raw water pump 120, a pretreatment tank 130, a dosing box 140, a fine filter box 150, a high-pressure pump 160 and an inorganic ceramic separation membrane 170 which are sequentially connected by pipelines.

[0049] The outlet of the inorganic ceramic separation membrane 170 is connected to the water production tank 180 through a pipeline, and the water production tank 180 is used to collect the clean water flowing out after filtration.

[0050] The concentrated liquid outlet of the inorganic ceramic separation membrane 170 is connected to the concentrated water tank 190 via a pipeline, and the concentrated liquid is collected by the concentrated water tank 190 .

[0051] Combination Figure 1 As shown, the raw water storage tank 110 is used to store and buffer the raw sewage entering the sewage treatment.

[0052] The raw water pump 120 is used to pump the sewage in the raw water storage tank 110 to the pretreatment tank 120 .

[0053] The pretreatment tank 120 is provided with at least one grid perpendicular to the flow direction to intercept floating objects in the sewage. Figure 1 As shown, the sewage discharged from production enters the subsequent treatment system after passing through the pre-treatment screen. The screen is used to intercept large floating objects in the sewage to ensure the normal operation of the subsequent treatment process and effectively reduce the operating load, providing guarantee for the long-term normal operation of the system.

[0054] Dosing box 140, combined Figure 2 As shown, it is equipped with a medicine storage container and a metering pump, and the metering pump is used to accurately pump the medicine in the medicine storage container to the output pipeline of the pretreatment tank to perform acid-base balance on the pretreated sewage.

[0055] The fine filter box 150 is provided with an MBR reaction tank inside thereof for preliminary fine filtering of the sewage. The activated sludge method is adopted in the MBR reaction tank to decompose the pollutants in the sewage by microbial oxidation and digestion.

[0056] The high-pressure pump 160 is disposed between the output end of the fine filter box 150 and the inorganic ceramic separation membrane 170 , and is used to pressurize and pump the sewage after preliminary fine filtration to the inorganic ceramic separation membrane 170 .

[0057] The inorganic ceramic separation membrane 170 uses its porous separation structure to perform secondary fine filtration on the pressurized sewage, intercepting the suspended particles, bacteria, and viruses therein to form a concentrated solution, and the filtered clean water flows out through the membrane pores.

[0058] In the embodiment of the present utility model, the inorganic ceramic separation membrane 170 is a solid membrane separation material, and inorganic ceramic materials such as aluminum oxide, zirconium oxide, titanium oxide and silicon oxide of different specifications are preferably used as a support body. The inorganic ceramic membrane formed by surface coating and high-temperature firing has the advantages of good chemical stability, high mechanical strength, controllable pore size, low pollution and long service life. In this embodiment, the multi-channel tubular ceramic separation filter membrane product OD 25*1178mm of Nanjing Hanshen Materials Technology Co., Ltd. is used as an example. Figure 4 However, it should be understood that the implementation of the present invention is not limited to the separation membrane product of this example.

[0059] Combination Figure 3 As shown, the aforementioned raw water pump 120, high pressure pump 160, and dosing box (i.e., dosing box metering pump) are electrically connected to a control system 200, and are controlled and operated by the control system. In the design of the utility model, the control system 200 particularly adopts an embedded PLC control system, and is configured with an input and output interface for user interaction, such as a touch screen, a combination of a screen and a keyboard and mouse device, etc., for the user (i.e., operator) to observe the system operation, including but not limited to sewage treatment flow, sewage treatment efficiency, concentrated water collection, clean water collection, and detection values ​​during sewage treatment, as well as parameters set or configured by the user for the treatment process.

[0060] Combination Figure 1As shown, a pH sensor pH1 is provided in the outlet pipeline of the pretreatment tank 130 to monitor the pH value of the sewage flowing out of the pretreatment tank. The pH value is a function of the concentration and type of salt or organic matter contained in the sewage. As the salt concentration increases, the osmotic pressure also increases. If the pressure remains constant, the higher the salt content, the lower the water flux. The increase in osmotic pressure offsets the driving force of the water inlet, resulting in a decrease in water flux and an increase in salt flux through the membrane. Based on the data measured by the pH sensor, the PLC can automatically calculate the amount of medicine to be added through a built-in program (implanted using an existing design program), and by accurately controlling the pumping of the metering pump, the calculated amount of medicine is added to achieve the effect of acid-base balance.

[0061] Combination Figure 1 As shown, a first flow meter F1 is provided in the pipeline between the output end of the raw water pump 120 and the pretreatment tank 130 for measuring the cumulative flow rate of the inlet water; a second flow meter F2 is provided in the pipeline between the outlet channel of the inorganic ceramic separation membrane 170 and the production water tank 180 for measuring the cumulative flow rate of the clean water after filtration.

[0062] The first flow meter F1 and the second flow meter F2 are both connected to the control system 200 via a sensor interface, and are used to upload the sensor-detected parameters, ie, the accumulated flow data, to the control system 200 .

[0063] Combination Figure 1 As shown, a third flow meter F3 is provided between the concentrated liquid outlet of the inorganic ceramic separation membrane 170 and the concentrated water tank 190 , which is connected to the control system 200 for real-time detection of the accumulated flow of the collected concentrated water and uploading it to the control system 200 .

[0064] Combination Figure 1 A first sludge meter S1 is provided in the pipeline between the output end of the raw water pump 120 and the pretreatment tank 130, for measuring the first SDI index of the inlet sewage. A second sludge meter S2 is provided in the pipeline between the concentrated liquid outlet of the inorganic ceramic separation membrane 170 and the concentrated water tank 190, for measuring the second SDI index in the concentrated liquid.

[0065] The first sludge meter S1 and the second sludge meter S2 are both connected to the control system 200 via a sensor interface, and are used to upload the sensor-detected parameter, namely the SDI index, to the control system 200 .

[0066] It should be understood that the sludge density index (SDI) of sewage is a very important water treatment maintenance parameter. By measuring the SDI value of the raw water sampling points before and after filtration, the operation status of the sewage treatment system can be effectively monitored.

[0067] In an embodiment of the utility model, the control system 200 (PLC control system) can determine the sewage treatment efficiency (the ratio of the two) based on the cumulative flow of clean water and the cumulative flow of incoming water, and send the first SDI index, the second SDI index, the pH value, the dosage of the metering pump and the sewage treatment efficiency parameters to the cloud server through the network transmission module.

[0068] The aforementioned network transmission module can particularly adopt a wireless network transmission module, such as a 4G or 5G module based on a cellular network.

[0069] Combination Figure 1 As shown, a first conductivity sensor C1 is provided in the outlet pipeline of the pretreatment tank 130 to detect the conductivity of the sewage flowing out of the outlet pipeline of the pretreatment tank. A second conductivity sensor C2 is provided in the pipeline between the outlet channel of the inorganic ceramic separation membrane 170 and the water production tank 190 to detect the conductivity of the filtered clean water flowing out of the outlet channel of the inorganic ceramic separation membrane.

[0070] The first conductivity sensor C1 and the second conductivity sensor C2 are both connected to the control system through the sensor interface module, and the detected conductivity is transmitted to the control system for characterizing the ion concentration in the sewage / clean water.

[0071] In the exemplary embodiment, the conductivity sensor adopts a multi-electrode conductivity sensor, such as nPro 7000-VP, InPro7108-VP / PEEK, etc., to achieve high-precision measurement of ion concentration in clean water and meet the application requirement of 10mS / cm.

[0072] As an optional implementation, combining Figure 1 As shown, a hardness meter H1 is provided in the outlet pipeline of the pretreatment tank and connected to the control system 200 through a sensor interface module. The hardness meter H1 is used to monitor the water hardness of the sewage flowing out of the pretreatment tank to characterize the total concentration of calcium and magnesium ions in the sewage.

[0073] Combination Figure 1 As shown, a thermometer T1 is provided in the output end pipeline of the fine filter box 150 for detecting the temperature of the sewage flowing out of the fine filter box after preliminary fine filtration.

[0074] The thermometer is connected to the control system 200 via a sensor interface module for uploading monitored sewage temperature parameters.

[0075] Combination Figure 1 As shown, pressure sensors (P1, P2, P3, P4) are provided in the outlet pipeline of the pretreatment tank, the output pipeline of the fine filter box, the output pipeline of the high-pressure pump and the water outlet channel of the inorganic ceramic separation membrane, which are respectively used to detect the pressure value of the fluid, i.e., sewage, flowing through the pipeline.

[0076] Each pressure sensor is connected to the control system 200 via a sensor interface module, and the detected pressure value parameters are uploaded in real time.

[0077] Combination Figure 1 As shown, a high-pressure backwashing device 175 is provided between the water production tank 180 and the inorganic ceramic separation membrane 170. Clean water in the water production tank 180 is passed through the high-pressure backwashing device 175 to backwash the inorganic ceramic separation membrane 170, and residual filtration intercepts on the inorganic ceramic separation membrane 170 are washed and removed. The purified water is reversely pressurized on the ceramic membrane to achieve backwashing of the membrane, prevent clogging of the membrane, extend the membrane replacement cycle, and improve the filtration efficiency.

[0078] As an optional embodiment, the high-pressure backwashing device 175 is connected to the control system 200. The control system 200 controls the start of the high-pressure backwashing device to backwash the inorganic ceramic separation membrane according to the pressure difference detected by the pressure sensors (the third pressure sensor P3 and the fourth pressure sensor P4) before and after the inorganic ceramic separation membrane. For example, when the difference between the pressure value detected by the fourth pressure sensor P4 and the pressure value detected by the third pressure sensor P3 exceeds a preset threshold value, it is determined that the inorganic ceramic separation membrane is blocked, and the backwashing is started to remove the retained materials such as mud, dirt, etc. by high-pressure washing, thereby increasing the service life of the membrane and its working efficiency, realizing automatic cleaning of the ceramic membrane, thereby realizing unmanned operation of the sewage treatment equipment and reducing maintenance costs.

[0079] As an optional embodiment, the control system 200 is configured to control the start of the high-pressure backwashing device to backwash the inorganic ceramic separation membrane according to a preset time period. For example, it can be configured by the user according to the actual sewage discharge situation, and backwashing is performed regularly according to a certain time period (such as one week, two weeks, one month, etc. depending on the actual situation).

[0080] As an optional embodiment, the control system 200 is configured to control the start of the high-pressure backwashing device to backwash the inorganic ceramic separation membrane based on the monitoring of the cumulative flow rate of water inlet reaching a preset threshold. For example, the user can configure it according to the actual sewage discharge situation and perform regular backwashing according to the accumulated total sewage treatment volume.

[0081] As an optional implementation, the high-pressure pump uses a multi-stage high-pressure centrifugal pump to pressurize the sewage to an optimal pressure state before it enters the ceramic separation membrane to achieve the optimal filtration efficiency.

[0082] In the embodiment of the utility model, the aforementioned raw water storage tank 110, raw water pump 120, pretreatment tank 130, dosing box 140, fine filter box 150, high-pressure pump 160, inorganic ceramic separation membrane 170, water production tank 180, concentrate tank 190, and high-pressure backwashing device 175 are all integrated and skid-mounted into the container to realize integrated skid-mounted assembly, commissioning, and operation, realize miniaturization and streamlined construction, facilitate transportation, and flexible installation, and are suitable for a variety of miniaturized sewage treatment point applications.
