[0002] Phosphorus-containing wastewater refers to wastewater containing high concentrations of phosphorus in industrial production, agricultural activities or domestic discharge. Phosphorus is an important nutrient element, but excessive phosphorus discharged into water bodies can cause water pollution and trigger environmental problems such as algal blooms and the death of aquatic organisms. For example, excessive phosphorus entering the water body will promote algae growth, leading to eutrophication of the water body, triggering algal blooms and destroying the balance of the aquatic ecosystem.

[0028] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0029] Reference Figure 1 and Figure 2 The utility model provides an embodiment: a sewage treatment electrolytic flocculation dephosphorization device, comprising a filter shell 1, a fixed cover 3 is fixedly installed on the left side of the filter shell 1, a servo motor 4 is fixedly connected to the left side of the fixed cover 3, the output end of the servo motor 4 passes through the left side of the fixed cover 3 and is fixedly connected to a rotating column 5, a filter plate 6 is fixedly connected to the outer wall of the rotating column 5, the right side of the filter shell 1 is connected to an electrolytic device 8, the right side of the electrolytic device 8 is connected to a collecting shell 9, a filter box 10 is slidably installed inside the collecting shell 9, a liquid injection valve 7 is connected to the left side of the fixed cover 3, and a dredging mechanism 2 is arranged on the top of the electrolytic device 8;

[0030] Specifically, the servo motor 4 is started so that the rotating column 5 drives the filter plate 6 to rotate, thereby realizing the preliminary filtration of the sewage. The filter plate 6 generates centrifugal force during the rotation process, which can effectively increase the filtration speed of the sewage and save time for the subsequent processing links. After the preliminary filtration is completed, the filtered sewage will enter the interior of the electrolysis device 8 through the continuous operation of the sewage extraction pump. In this link, the electrolysis device 8 removes phosphorus in the sewage by electrolytic flocculation. This method has the advantages of high efficiency and environmental protection, which can not only improve the phosphorus removal efficiency, but also reduce the cost of sewage treatment. During the operation of the electrolysis device 8, a colloidal flocculant will be produced. This flocculant has a good flocculation effect and can further purify the water quality. The sewage treated by the electrolysis device 8 will enter the collection shell 9, where the task is to collect and process the larger particles and impurities still contained in the sewage. Finally, the sewage in the collection shell 9 will be filtered again through the filter box 10. The main function of the filter box 10 is to remove the remaining larger particles and impurities in the sewage to ensure that the quality of the discharged water meets the environmental protection standards. The clean water treated by the filter box 10 can be safely discharged into the river, achieving the purpose of removing phosphorus from sewage.

[0031] Reference Figure 1 and Figure 3 The dredging mechanism 2 includes a protective shell 201, the bottom wall of the protective shell 201 is fixedly connected to the top wall of the electrolysis device 8, a pressure pump 202 is fixedly installed on the inner bottom wall of the protective shell 201, the extraction end of the pressure pump 202 is connected to an extraction pipe 203, the right end of the extraction pipe 203 is connected to the front side of the collecting shell 9, the output end of the pressure pump 202 is connected to a connecting pipe 204, the bottom end of the connecting pipe 204 is connected to a delivery pipe 205, the left end of the delivery pipe 205 is connected to a first nozzle 206, and the right end of the delivery pipe 205 is connected to a second nozzle 207;

[0032] Specifically, the booster pump 202 plays a key role, which is responsible for extracting the water that enters the collection shell 9 after secondary filtration. The collection shell 9 serves as a temporary storage device to receive filtered water from various places. The continuous operation of the booster pump 202 ensures the fluidity of the water and ensures the efficient operation of the entire system. The connecting pipe 204 and the delivery pipe 205 are important components of the water flow channel, which transport water from the collection shell 9 to the first nozzle 206 and the second nozzle 207 respectively. These two nozzles play a vital role. They release the water flow in a jetting manner to form a high-speed water flow to achieve the dredging and flushing of the filter plate 6 and the filter box 10. The filter plate 6 and the filter box 10 are the core parts of the filtering equipment. They are responsible for intercepting larger particles and preventing them from entering the water flow. However, during long-term use, the filter plate 6 and the filter box 10 may be blocked, affecting the water flow delivery effect. In order to solve this problem, our equipment uses a jet of water for dredging and flushing. The jetted water flow has a high impact force and can effectively remove the blockages on the filter plate 6 and the filter box 10. In this way, it is possible to prevent larger particles from clogging the filter plate 6 and the filter box 10, thereby ensuring smooth water flow delivery. In addition, the jet water flow can also regularly clean the filter equipment, extend its service life, and reduce the maintenance cost of the equipment.

[0034] Specifically, the rubber pad 208 can protect the connection between the left side of the delivery pipe 205 and the filter shell 1, thereby reducing the wear of the delivery pipe 205. The control switch 12 is electrically connected to the servo motor 4, the electrolysis equipment 8 and the pressure pump 202 respectively, so that the control switch 12 can open and close the device. The connecting plate 14 and the support column 15 make the device more stable during operation.

[0037] Working principle: When sewage treatment begins, the sewage extraction pump is connected to one end of the injection valve 7 to start the initial filtration of the sewage. The servo motor 4 is started to drive the filter plate 6 to rotate, and the centrifugal force generated by the rotation of the filter plate 6 can increase the initial filtration rate of the sewage. The initially completed sewage enters the interior of the electrolytic device 8 through the continuous operation of the sewage extraction pump, so that the electrolytic device 8 removes phosphorus from the sewage by electrolytic flocculation, thereby improving the phosphorus removal efficiency. At the same time, the colloidal flocculation formed by the working reaction of the electrolytic device 8 can complete the water quality treatment function, so that after filtration, The sewage enters the interior of the collecting shell 9, and then the filter box 10 collects the larger particles and impurities contained in the sewage again, and finally the filtered water is discharged into the river to complete the purpose of sewage phosphorus removal, and the pressure pump 202 is started to extract the water entering the collecting shell 9 after the secondary filtration. Through the continuous operation of the pressure pump 202, the water is respectively transported to the first nozzle 206 and the second nozzle 207 through the connecting pipe 204 and the delivery pipe 205 for spraying, so that the filter plate 6 and the filter box 10 can be cleared and flushed by the sprayed water flow, so as to achieve the purpose of preventing larger particles from clogging the filter plate 6 and the filter box 10 and affecting the water flow delivery.
