By setting up multiple sedimentation tanks, wastewater undergoes sedimentation and filtration at different stages, effectively achieving stratified treatment and removing contaminants of varying particle sizes. Furthermore, combined with an automatic cleaning mechanism, the sedimentation tanks can be regularly maintained to reduce sediment accumulation and improve system operating efficiency.

[0022] The filtering device 208 comprises four fixed blocks 2081 which are arranged in pairs, and the fixed blocks 2081 are fixedly connected with filtering plates 2082. The filtering plates 2082 are uniformly and equidistantly provided with a plurality of filtering inclined holes 2083, and the bottom of the filtering plate 2082 is provided with a supporting beam 2084. The plurality of filtering inclined holes uniformly arranged on the filtering plate can effectively increase the filtering area, the inner surface of the inclined hole can filter and adsorb dust particles, improve the filtering efficiency when the water flow passes, and ensure that more solid impurities and pollutants can be intercepted. The design of the inclined hole helps to realize the uniform distribution of the water flow, slows down the water flow rate, and avoids the water flow from being concentrated in a certain place.

[0023] Working principle: sewage enters the water purification filter tank 2 through the water inlet pipe 4. Here, the sewage will flow to multiple sedimentation tanks for layered sedimentation. The first sedimentation tank 201 is the first stage of sewage treatment. The sewage stays here for a period of time, and the solid particles sink to the bottom under the action of gravity and fall on the first dust accumulation block 202. The bottom side of the sedimentation tank is provided with a cleaning water outlet 203 for regular removal of sediments. The upper end of the sedimentation tank is provided with a plurality of first water inlets 204 on one side. After sedimentation, the sewage flows into the adjacent second sedimentation tank 205. The design of this tank continues to sediment the sewage and further removes suspended solids. The upper end of the second sedimentation tank 205 is provided with a second water inlet 206 on one side to guide the treated water into the third sedimentation tank 207. Inside the third sedimentation tank 207, there is a filtering device 208. The sewage is filtered more carefully here to ensure that most of the particulate matter is removed. The filtering device 208 is composed of four fixed blocks 2081 and a plurality of filtering plates 2082. The filtering inclined holes 2083 uniformly arranged on the filtering plates can effectively increase the filtering area and improve the filtering efficiency of the water flow. When the water flow passes through the inclined holes, the flow rate slows down, which helps to adsorb and intercept solid impurities. The device is provided with a cleaning device 3, which comprises a rotating motor 31 and a cleaning brush 32. The cleaning brush regularly removes sediments at the bottom of the first sedimentation tank 201 to ensure the cleanliness of the environment in the sedimentation tank. After multiple stages of treatment, the sewage is discharged through the water outlet pipe 5 and can meet the discharge standard or be used for subsequent utilization such as irrigation and industrial water.
