A composite ecological high-load soil infiltration system

Abstract

The invention relates to a complex ecological high-load soil infiltration system. The complex ecological high-load soil infiltration system comprises a rapid infiltration layer, a slow infiltration layer, a drainage layer and an overhead tank, wherein the rapid infiltration layer is defined as a top layer, the slow infiltration layer is defined as an intermediate layer, the drainage layer is defined as a bottom layer; the overhead tank is arranged on one side of the top part of the rapid infiltration layer, the bottom of the overhead tank is provided with a water distribution pipe which is communicated with the overhead tank, the water distribution pipe horizontally extends into the top part of the rapid infiltration layer; a plurality of water outlets are formed in the bottom of the water distribution pipe; one side of the bottom of the drainage layer is provided with a drainage pipe which is communicated with the drainage layer; the thickness of the rapid infiltration layer is 40-60cm, and the rapid infiltration layer consists of soil, bamboo powder, wood powder and gravels with the volume ratio of 2:2:2:1; the thickness of the slow infiltration layer is 40-60cm, and the slow infiltration layer consists of soil, bamboo powder and wood powder with the volume ratio of 10:3:3; the thickness of the drainage layer is 5-10cm, and the drainage layer consists of gravels. The complex ecological high-load soil infiltration system is not easy to block, is rapid in infiltration speed, is good in sewage treating effect and is high in durability.

Description

technical field [0001] The invention relates to the technical field of water, waste water, sewage or sludge treatment, in particular to a compound ecological high-load soil infiltration system. Background technique [0002] Soil infiltration treatment system is an artificially enhanced sewage ecological engineering treatment technology. It makes full use of the physical and chemical characteristics of soil animals, soil microorganisms, plant roots and soil that live in the soil below the surface to purify sewage. Small sewage land treatment system. The fillers used in common soil infiltration systems are mostly stones, polymer materials, gravel, sand, etc. The proportion of soil is very small or even non-existent. The growth environment of microorganisms is single and the diversity is insufficient, resulting in an unsustainable sewage treatment effect. [0003] Distributed sewage treatment technologies similar to the technology of the present invention mainly include slow s...

AI Technical Summary

Problems solved by technology

[0007] The invention provides a compound ecological high-load soil infiltration system. The technical problem to be solved is that the slow and sudden infiltration method is easy to block, the infiltration speed is slow, and the sewage treatment effect is reduced and the persistence is low after the infiltration speed is accelerated. question
