Corrugated cavity type soil infiltration system

Abstract

The invention discloses a corrugated cavity type soil infiltration system, and the system comprises a septic tank, a water distribution system, an infiltration system and a soil infiltration system, sewage enters the water distribution system after being pretreated by a septic tank, enters the infiltration system from the water distribution system and infiltrates into the soil infiltration systemfor infiltration, the infiltration system is composed of a plurality of connected infiltration cavities, the sewage enters the infiltration cavities sequentially through water inlets of the infiltration cavities, and the infiltration cavities are communicated with the water distribution system; the percolation cavity enters surrounding soil after percolation, the inner wall of the cavity wall of the percolation cavity is a corrugated inner wall, and a plurality of shutter type percolation holes are formed in the cavity wall of the percolation cavity. According to the invention, the infiltration cavity adopts the corrugated cavity, so the infiltration area and the sewage infiltration flow of the cavity are increased, and the sewage treatment capacity is improved; the shutter type infiltration holes are formed in the side wall, the soil is prevented from entering the cavity, gravel filter materials do not need to fill the periphery of the cavity, and engineering investment is saved.

Description

technical field [0001] The invention relates to the technical field of sewage treatment, in particular to a corrugated chamber soil infiltration system. Background technique [0002] The underground infiltration system usually refers to a sewage treatment system composed of a septic tank and an underground infiltration device. Under the influence of diffusion movement, sewage is purified through physical interception, physical and chemical adsorption, chemical precipitation, microbial degradation, animal and plant action, etc. during this migration process. The underground infiltration system has the advantages of good water quality, low investment, simple management, no damage to the landscape, and no odor when the device is located underground, so it has become an increasingly important sewage treatment method at home and abroad. [0003] Traditional soil infiltration systems are infiltration pit structures. It is mainly composed of a pretreatment pool and a gravel pile....

AI Technical Summary

Problems solved by technology

The underground infiltration pit is also a relatively primitive underground infiltration system. The disadvantage is that it occupies a large area, the sewage treatment capacity is small, and the sand and gravel filter material undertakes a high cost. It is mainly suitable for sewage with a relatively small flow rate.

[0004] In summary, the traditional soil infiltration system has problems such as high cost of sand and gravel filter materials and large floor space.
