Introduction to the process of sewage treatment equipment in residential areas:
The transformation of domestic sewage treatment technology in residential areas has gone through a process from single process to combined process. From the perspective of whether it is aerobic, it follows the trajectory of "anaerobic → aerobic → anaerobic+aerobic → anaerobic+anoxic". From the perspective of removal targets, in the past, the sewage in residential areas was only treated for suspended substances through septic tanks, which cannot meet environmental discharge requirements. Therefore, it is necessary to improve the existing sewage treatment methods.

Characteristics of buried sewage treatment equipment in residential communities:
(1) Residential communities are relatively dispersed, with low sewage flow and good biodegradability, and should prioritize the use of biofilm treatment technology. The biofilm method has the advantages of high microbial concentration, long food chain, no sludge swelling, and good sludge settling performance.
(2) Some newly built residential communities have limited land resources, and priority should be given to sewage treatment processes that occupy less land, and certain measures should be taken in the design. Nowadays, it is generally designed as underground or semi underground, forming a pattern of underground sewage treatment stations and ground green spaces or flower beds, which can beautify the environment. However, when designing in this way, attention should be paid to issues such as burial depth, equipment lifting, ventilation requirements, and odor treatment.
(3) Due to the limitations of the number and professional quality of community management personnel, priority should be given to using processes that are more convenient for operation and maintenance management, and efforts should be made to improve the automation level of operation and management.
(4) The construction period of residential communities is tight, and the transformation of sewage treatment facilities from structures to equipment seems to be an inevitable trend. Adopting prefabricated residential communitiesSewage treatment equipmentEasy to install, short construction period, and convenient for maintenance.
