Subsurface sewage disposal system

Abstract

The invention discloses a subsurface sewage disposal system. The subsurface sewage disposal system is characterized by comprising a water-inlet filtering system, a multilevel sewage disposal system, afloating island biological disposal system, a standing detection pond and a up-to-standard discharging system; sewage enters the water-inlet filtering system and is disposed to enter the multilevel sewage disposal system, a water body passing through the multilevel sewage disposal system is pumped to enter the floating island biological disposal system, the water body after being disposed throughthe floating island biological disposal system enters the standing detection pond, and the water body enters the up-to-standard discharging system after the detection result is up to standard, and isdischarged through the up-to-standard discharging system. According to the subsurface sewage disposal system, the subsurface water pollution problem is solved with the systematic sense, the overall integration technology is used, and closed cycling of the governing, recovering and recycling scheme is formed. A base layer of a whole water ecosystem and a base layer of the subsurface sewage disposal system are recovered and reinforced, overall repairing and reinforcement of the whole water cycling system are thus achieved, the water quality is improved, and it is achieved that subsurface sewageis recycled.

Description

technical field [0001] The invention relates to the field of underground sewage treatment, in particular to an underground sewage treatment system. Background technique [0002] With the rapid development of my country's economy, the total amount of sewage discharge continues to increase, but the treatment rate of sewage has not increased synchronously. A large amount of waste water directly enters various water bodies without treatment, exceeding the self-purification limit of the water body, which leads to water pollution. The destruction of the ecosystem is becoming more and more serious, and water shortage has become a relatively common water ecological disaster. As the base layer of the water ecosystem, the groundwater system must strictly prevent and treat underground sewage. At present, my country's ordinary sewage treatment has the following defects, which cannot solve the problem of underground sewage: 1. Insufficient understanding of the complexity of underground s...
