Bottom mud repairing structure with purification function

Abstract

The invention belongs to the technical field of water environment treatment, and particularly relates to a bottom mud remediation structure with a purification effect. The structure comprises a bottom mud repairing layer used for covering the upper surface of bottom mud and a stabilizing layer used for resisting water, wherein a purifying layer of a gap structure is arranged between the bottom mud repairing layer and the stabilizing layer; the bottom mud repairing layer is formed by mixing and solidifying clay, plant cellulose, plant lignin and plain soil; the purification layer is a precipitation oxidation layer which is prepared by mixing microorganisms, ferric chloride and zeolite powder and has a honeycomb-shaped cross section. The bottom mud repair layer can well repair the covered bottom mud and has good reduction capacity on pollutants released by the bottom mud; the stabilizing layer can well protect the bottom mud and play a role in stabilizing the bottom mud, so that secondary pollution caused by upturning of the bottom mud due to water flow is avoided; the purification layer is used for adsorbing and purifying suspended particles and pollutants in the water body, so the purification treatment of the water body is realized.

Description

technical field [0001] The invention belongs to the technical field of water environment treatment, and in particular relates to a bottom mud restoration structure with purifying effect. Background technique [0002] With the rapid development of my country's economy, a large amount of industrial wastewater and domestic sewage are directly discharged into rivers, lakes and other water bodies, resulting in serious pollution of rivers, lakes and reservoirs. At present, 85% of the lakes in our country have experienced eutrophication in different degrees, which has seriously affected the production and life of the surrounding residents. [0003] At present, many cities still have the phenomenon of black and odorous water bodies, and the water bodies cannot be effectively treated, or even if the treatment reaches the standard in a short period of time, there will be a phenomenon of "turning black and smelling". A considerable part of these phenomena is due to the bottom of rivers...

AI Technical Summary

Problems solved by technology

[0005] The purpose of the present invention is to solve the problems in the prior art that the removal of pollutants released by the bottom mud is poor, the construction is difficult, the covering is large in size, easy to produce secondary pollution, and the construction is easy to destroy the ecological system balance in the bottom mud. and other shortcomings, and proposed a sediment repair structure with purification effect
