[0030] When the second control valve 10 is opened, the raw liquid containing impurities after front-end treatment is introduced into the filter tank 1 through the liquid inlet pipe 3, and then flows into the lower half of the filter tank 1 through the center connecting pipe 4. Under the action of gravity, the precipitates in the raw liquid naturally sink and deposit on the inner bottom surface of the filter tank 1. When the raw liquid flows through the annular water distributor 5, the first baffle 503 and the second baffle 504 intercept the precipitates and suspended solids in the raw liquid, so that they cannot continue to flow upward, thereby improving the filtering effect of the annular water distributor 5. When the raw liquid flows upward through the filler 7, the filler 7 intercepts solid particles, suspended solids or other impurities in the liquid, adsorbs and filters the impurities in the raw liquid, and can effectively remove these impurities. The filter assembly 6 can prevent the filler 7 from being carried out of the filter tank 1 during liquid flow, so as to ensure that the filler 7 always plays a role in the filter tank 1. The water cap 602 can further filter smaller impurities in the raw liquid, thereby improving the quality of the filtered water. When the first control valve 9 is opened, the raw liquid filtered by the filter assembly 6 is discharged outward through the liquid outlet pipe 2. When a certain amount of precipitates, impurities or waste generated during the treatment process accumulates in the filter tank 1, the blowdown valve 11 is opened to timely discharge through the blowdown pipe 8, so as to keep the inside of the filter tank 1 clean. The solid-liquid separation of the raw liquid can be realized, so as to effectively remove all impurities in the raw liquid, and the treated raw liquid can meet the requirements of subsequent treatment or discharge.
