[0031] Furthermore, three water inlet holes 14 are opened on one side of the fixed plate 13, and water pipes 20 are fixedly sleeved on the outer ends of the three water inlet holes 14, and the other end of the water pipe 20 is fixedly connected to the upper end of the water pump 8, and a drain pipe 21 is fixedly installed in the center of the front end of the water pump 8, and the drain pipe 21 extends through the outer end of the box body 1 to the interior of the filter area 10.

[0033] Working principle: Construction sewage enters the mixing zone 9 of the box 1 through the feed port 2. In the mixing zone 9, the mixing assembly consisting of two sets of screws 22, bearings 23 and scrapers 24 starts to work. The rotating motor 6 drives the screw 22 to rotate, driving the scraper 24 to rotate in the mixing zone 9 to mix the sewage. The purpose of mixing is to precipitate large particles of impurities in the sewage. During the mixing process, the sand and other large particles of impurities in the sewage gradually settle to the sand collecting plate 12 under the action of gravity and centrifugal force, and slide into the bottom of the mixing zone 9 through the sand collecting plate 12. The stirred sewage is pumped into the water pump 8 through the water inlet hole 14 on the fixed plate 13 and the water pipe 20. The sewage is pumped into the filtration area 10 through the drainage pipe 21 to form a cycle. The sewage passes through the quartz sand particle 16 layer, and most of the suspended particles are intercepted. Then, the sewage after preliminary filtration enters the activated carbon fiber 17 layer. The activated carbon fiber 17 uses its adsorption performance to remove pigments, odors and organic matter in the water. Finally, the water passes through the ultrafiltration membrane 18 layer to further remove bacteria, viruses and other tiny particles. The filtered clean water is discharged through the outlet pipe 3. The rotary valve is used to control the opening and closing of the outlet pipe 3. The sand settled during the stirring process accumulates at the bottom of the stirring zone 9. The sand and impurities are discharged by regularly opening the rotary valve of the sand discharge pipe 4 to keep the inside of the device clean.
