Domestic sewage treatment
Domestic sewage refers to the mixed liquid of various sewage produced by People's Daily life, including flushing drainage, kitchen drainage, laundry drainage, swimming pool sewage and shower drainage。Sewage produced in the course of human life is one of the main pollution sources of water bodies。Mostly feces and washing sewage。Domestic sewage contains a lot of organic matter，Such as cellulose, starch, sugar and fat protein;Also often contains pathogenic bacteria, viruses and parasite eggs;Inorganic salts of chloride, sulfate, phosphate, bicarbonate and sodium, potassium, calcium, magnesium, etc，In general, especially good biodegradability，Nitrogen, phosphorus, sulfur content is high，Under the action of anaerobic bacteria，Malodorous substance。
The buried domestic sewage treatment equipment adopts the world's advanced biological treatment technology, which integrates the removal of BOD5, COD and NH3-N, and is the most efficient sewage treatment equipment at present。The general water quality of domestic sewage is as follows: the water temperature is 10-20℃,COD is about 200-500mg/l,BOD5 is about 100-300mg/l,SS is about 100-250mg/l, and PH is about 6.5-7.5, the treated domestic sewage can meet the national sewage comprehensive discharge standard GB8978-1996 "sewage discharge standard" in the first level discharge standard, water reuse standard, "urban sewage treatment plant pollutant discharge standard" (GB18918-2002) standard。
Product features:
The equipment can be buried below the surface, and the surface can be used as afforestation or square land;
The equipment does not cover surface area, does not need to build houses, and does not need heating and insulation;
The operation cost of the equipment is low, and the equipment can be fully automatic according to the set water level control mode。
Process flow:
Domestic sewage → septic tank → grille → regulating tank → pump → Biochemical treatment system → disinfection → drainage
Process features:
▼ Low operating costs, less investment;▼ Simple processing process, easy operation and management;
Strong impact load resistance, stable biological chain, good treatment effect;
▼ The processing system has no odor and low noise;▼ High sludge consumption rate, small sludge production;
Scope of application:
Residential quarters, enterprise dormitories, highway service area sewage treatment
Coal mine sewage treatment, villa area sewage treatment, school sewage treatment
New rural communities, township sewage treatment, areas without urban pipe networks, etc
