What is the working principle of underground sewage treatment equipment?

Author: yuedongzs.cn

Underground sewage treatment equipment
Underground sewage treatment equipment technology refers to sewage treatment technology in which the main structures in sewage treatment facilities are buried underground or semi-underground. It mainly has the advantages of small floor area, low noise, no odor, little impact on the climate, convenient handling, and high processing efficiency. Based on the latest research achievements of domestic scholars on underground sewage treatment technology, this paper systematically introduces the characteristics and classification of underground sewage treatment technology. The buried sewage treatment equipment is a modular and efficient sewage biological treatment equipment. It is a sewage biological treatment system with biofilm as the main body of purification. It fully utilizes biofilm reactors such as anaerobic biological filters and touch oxidation beds. It has the characteristics of large biological density, strong pollution resistance, low power consumption, stable operation and operation, and convenient maintenance.

Effect principle of underground sewage treatment equipment and anaerobic biological filter

1. Filtration effect: fillers trap large particles and suspended matter filtered into water

2. Hydrolysis effect: Anaerobic microorganisms can hydrolyze insoluble substances of large molecules into soluble substances of small molecules

3. Absorption effect: Anaerobic microorganisms absorb and absorb organic pollutants in water. Part of it is used for its own growth and reproduction. Part of it is sealed by U-shaped water in the form of biogas.

4. Nitrogen removal effect: The denitrifying bacteria that return the effluent from the touch oxidation bed to the anaerobic microorganism in the anaerobic filter can use the nitrate nitrogen in the reflux water and convert it into nitrogen to remove nitrogen in the sewage. After the rural sewage is treated by the anaerobic filter, the concentration of suspended solids, organic pollutants, and nitrogen is reduced, and the subsequent load of touching the oxidation bed is reduced.
