Buried sewage treatment equipment is widely used in living quarters, villas, office buildings, stations, airports, docks and other places. How does the buried sewage treatment equipment treat sewage? What are the treatment methods of buried sewage treatment equipment?

1. Biological contact oxidation method: the biological contact oxidation method is used to treat wastewater, that is, the biological contact oxidation process is used to fill the biological reaction tank with fillers. The oxygenated sewage submerges all the fillers and flows through the fillers at a certain flow rate. The filler is covered with biofilm, and the sewage is widely contacted with the biofilm. With the metabolism of microorganisms on the biofilm, the organic pollutants in the sewage are removed, so that the sewage can be purified.

2. Physical treatment method: wastewater treatment method for separating and recovering insoluble suspended pollutants (including oil film and oil droplet) in wastewater through physical action.

3. Chemical treatment method: It refers to the wastewater treatment method that separates and removes dissolved and colloidal pollutants in wastewater or converts them into harmless substances through mass transfer of chemical reaction.

4. Biological treatment method: It refers to the wastewater treatment method that converts the organic pollutants in solution, colloid and micro suspension into stable and harmless substances through the metabolism of microorganisms. According to different microorganisms, biological treatment methods can be divided into aerobic biological treatment and anaerobic biological treatment.

Buried sewage treatment equipment is a modular high and small sewage treatment equipment, which has the characteristics of strong pollution resistance, low power consumption, stable operation and convenient maintenance. Therefore, the system has broad application prospects and promotion value.
