Source of rural domestic sewage:

Sewage produced from human life is one of the main sources of water pollution. It is mainly excrement and washing water. The amount of daily sewage discharged per person in the city is 150 - 400L, which is closely related to the living standard. Domestic sewage contains a large number of organic substances, such as cellulose, starch, sugar and fat protein, and also often contain pathogenic bacteria, viruses and parasite eggs; inorganic salts of chloride, sulfate, phosphate, bicarbonate and sodium, potassium, calcium, magnesium and so on. The main characteristics are nitrogen, sulphur and phosphorus, which are easily generated by anaerobic bacteria.

Characteristics of rural sewage treatment equipment:

1, The removal efficiency of pollution index is high, the removal rate of BOD is 84% ~ 91%, and the indexes of effluent meet the national discharge standard.

2, The packing area is large, the microorganism is easy to implant, can improve the removal of organic matter and make the effluent stable and reliable.

3, The process is mature, less mud production, good impact load performance, simple operation management and the system operation is stable and reliable. According to the actual situation, the state can be adjusted at any time to achieve the best effect of the effluent.

4, sewage treatment equipment is small in size, light in weight, easy to transport and easy to install.

Treatment process of rural sewage:

The quality of domestic sewage is characterized by high organic matter, such as starch, protein, oil,nitrogen, phosphorus, and other inorganic materials, as well as people's hair, in addition, it also contains pathogenic microbes and more suspended substances. Combined with the characteristics of the water quality of the rural domestic sewage and the related cases, we will adopt the Biochemical treatment technology - contact oxidation method as the main treatment.

The index design consists of six parts: (1) Initial sink; (2) Contact oxidation pool; (3) Two sink; (4) Disinfection pool, Disinfection device; (5) Sludge pool; (6) Wind machine room and fan.
