Buried domestic sewage treatment technology refers to sewage treatment technology in which the main structure in the sewage treatment facility is buried underground or semi-underground. It mainly has the characteristics of small area, low noise, no peculiar smell, little influence by climate, convenient management, and high processing efficiency.
The buried sewage treatment equipment is a modular high-efficiency biological sewage treatment equipment. It is a sewage biological treatment system with biofilm as the main body of purification. It makes full use of biofilm reactors such as anaerobic biofilter and contact oxidation bed. It has the characteristics of high biological density, strong pollution resistance, low power consumption, stable operation and convenient maintenance.
The working principle of buried domestic sewage treatment and anaerobic biological filter
1. Filtration: The filler intercepts large particles and suspended matter filtered into the water
2. Hydrolysis: Anaerobic microorganisms can hydrolyze insoluble substances of large molecules into soluble substances of small molecules
3. Absorption: Anaerobic microorganisms adsorb and absorb organic pollutants in the water, part of which is used for their own growth and reproduction, part of which is sealed by U-shaped water in the form of biogas
4. Denitrification: Denitrifying bacteria that return the effluent from the contact oxidation bed to the anaerobic microorganisms in the anaerobic filter can use the nitrate nitrogen in the return water and convert it into nitrogen to remove the nitrogen in the sewage. After the rural sewage is treated by the anaerobic filter, the concentration of suspended solids, organic pollutants and nitrogen is also reduced, and the subsequent load of contacting the oxidation bed is also reduced.
