standing and precipitating sludge: then sewage enters a sludge sedimentation tank (12) for sedimentation, so that sludge in the water is sedimented at the bottom for layering, and a large amount of sludge is accumulated after multiple times of sedimentation and can be pushed, scraped and discharged through a sludge treatment mechanism (2);
And (3) aeration biodegradation: aeration is generated in the aeration filter tank (13) to carry out oxygenation and biodegradation on sewage, remove pollutants and improve water quality;
Removing turbid sand and filtering: filtering the sewage through sand in a sand filter (14) to remove floating matters in the water, so that the water is clearer;
dechlorination, disinfection and water purification: and (5) disinfecting the sewage subjected to multiple times of filtration, and reusing the sewage.
