Domestic sewage treatment is a variety of organisms produced by organisms, including toilet flushing, kitchen drainage, water absorption, swimming pool sewage treatment and laundry drainage.

The main feature of domestic sewage treatment is that the main content of phosphorus is high, and the treatment method is mainly biochemical. The sewage and sewage pipeline network is transformed into a septic tank, and the supernatant discharge of the septic tank is discharged after the treatment reaches the corresponding standard. The use of structural carriers enables the processes of aerobic, anaerobic, and facultative to occur in a single system, thereby reducing the organic matter, nitrogen, and phosphorus in the sewage to meet the emission requirements.

The automatic self-cleaning filter ordered by Russian customers is located in the secondary filtration treatment system to secondary filter the suspended solids after primary filtration, so as to achieve the effect of recycling. The backwash filter strainer adopts stainless steel shell and Johnson tube filter element to prolong the service life of the filter. The full-automatic PLC controller can control the filtering and self-cleaning state according to the pressure and time difference. Simple operation and management, easy automation, simple structure, simple installation, less land occupation and easy transportation. Organically combined with auxiliary facilities to realize self inspection, self repair and remote control of the system, with reliability.
