Introduction
Buried sewage treatment equipment adopts the world's advanced biological processing technology to remove BOD5, COD and NH3-N. At present, it is the most efficient sewage treatment equipment and it is widely used in high-level hotel, villa, residence community and other fields.

working principle
The buried sewage treatment equipment is a kind of modular and efficient sewage biological treatment equipment, which is a biological treatment system of biofilm as the main body of the purification. The biofilter reactor, such as anaerobic biological filter and contact oxidation bed, With the biological density, pollution resistance, low power consumption, operation and stability, easy maintenance features.

Advantages
1. Integrated sewage treatment equipment has light weight, thus is convenient for transportation and installation;
2. Adopting FRP, carbon steel and stainless steel to improve corrosion resistance and ageing resistance;
3. It does not need heating and thermal insulation, thus it realizes the integration of system to a maximum extent;
4. Pollution-free, no noise, no odor, less secondary pollution;
5. Not limited by the amount of sewage, can be used alone or together;
6. The whole equipment treatment system is equipped with PLC automatic electrical control system and equipment fault alarm system.

Application
Hotel, restaurant, nursing home, hospital, residence, village, town, station, airport, habour, wharf, ship, factory, mine, tourist spot, beauty spot, and other fields.
