Underground domestic sewage treatment equipment is an integrated system that embeds sewage treatment facilities underground, and purifies domestic sewage through technologies such as biodegradation, physical filtration, and chemical treatment. The core principle is to use the metabolic action of microorganisms to decompose organic matter, combined with precipitation, disinfection and other processes, ultimately making the effluent meet national discharge standards or reuse requirements.
1、 Main features and advantages
Space saving
The equipment is buried underground, does not occupy surface space, and can be used for greening or other purposes above, suitable for areas with tight land.
Environmentally friendly
Reduce noise and odors, with minimal impact on the surrounding environment, suitable for sensitive places such as residential areas and scenic spots.
Efficient processing
By using biological treatment technologies such as activated sludge process, A/O process, MBBR process, etc., the organic matter removal rate exceeds 95%, and the effluent quality is stable and meets the standard.
High degree of automation
Fully automated operation, low maintenance costs, and no need for dedicated personnel to be on duty.
2、 Typical application scenarios
Rural areas: Treat dispersed domestic sewage and improve rural environment.
Residential communities/office buildings: Save space and reduce interference with residents’ lives.
Tourist attractions/schools: Concealed design to maintain beautiful scenery.
