Domestic sewage solutions

solved problem:

Domestic sewage is wastewater discharged by residents in their daily lives. It mainly comes from residential buildings and public buildings, such as residences, offices, schools, hospitals, shops, public places and industrial enterprise toilets. The pollutants contained in domestic sewage are mainly organic matter (such as protein, carbohydrate, fat, urea, ammonia nitrogen, etc.) and a large number of pathogenic microorganisms (such as parasite eggs and intestinal infectious viruses, etc.). The organic matter present in domestic sewage is extremely unstable and easily corrupts to produce odor. Bacteria and pathogens multiply massively using organic matter in domestic sewage as nutrients, which can lead to the spread of infectious diseases. Therefore, domestic sewage must be treated before discharge

Wastewater characteristics:

It mainly comes from urban domestic sewage, hospital sewage, garbage and surface runoff. The characteristics of pathogenic microorganisms are: ① Large number; ② Wide distribution; ③ Long survival time; ④ Fast reproduction rate; ⑤ Easy to develop resistance and difficult to eliminate; ⑥ After traditional secondary biochemical sewage treatment and chlorine disinfection, a certain Some pathogenic microorganisms and viruses can still survive in large numbers; such pollutants actually enter the human body through various ways and survive in the body, causing human diseases.

Common wastewater treatment methods:

Biochemical methods are generally used to treat domestic sewage, because the BOD5/CODcr of domestic sewage ≈ 0.5 and is highly biodegradable. The contact oxidation method has the advantages of high volume load, short residence time, good organic matter removal effect, simple operation and small footprint. For this reason, we chose the contact oxidation method with mature technology and reliable operation.

The third-generation intelligent biochemical integrated machine equipment for domestic sewage independently developed, designed and produced by Baihuipu has the characteristics of efficient treatment, energy saving and environmental protection, can be buried underground, small footprint, simple debugging and stable operation.
