domestic wastewater treatment machine is an indispensable environmental protection equipment in modern society. It removes harmful substances from wastewater through a series of physical, chemical, and biological processes to meet discharge standards.

Domestic sewage treatment equipment is mainly suitable for the treatment and discharge of daily domestic sewage in fields such as restaurants, high-end residential communities, hotels, hospitals, etc. At present, domestic sewage treatment equipment has developed relatively maturely.

Biological contact oxidation method is one of the domestic sewage treatment machine processes and is also a relatively popular domestic sewage treatment equipment process. It has the advantages of simple installation and debugging, convenient post maintenance, and good sewage filtration effect. The process mainly consists of seven parts: grid anoxic tank biological contact oxidation tank secondary sedimentation tank disinfection tank sludge tank automatic control cabinet air room.

Wastewater treatment can be basically divided into four methods: physical methods, chemical methods, physicochemical methods, and biological methods.

Classification of sewage treatment methods:

1. Physical methods: Mainly using precipitation, magnetic separation, air flotation, filtration and other methods.

2. Chemical method: mainly using chemical precipitation method, neutralization method, oxidation-reduction method, coagulation precipitation method, etc

3. Physical and chemical methods: mainly using ion exchange, stripping, adsorption, and extraction

4. Biological method: mainly using biofilm method, activated sludge method, biological nitrogen and phosphorus removal method, and anaerobic method.
