Substrate structural system of horizontal flow manual wet land

Abstract

The invention discloses a substrate structural system of a horizontal flow manual wet land, comprising an anti-seepage structure, an absorbent purifying module, a blockage preventive module and an ecological planting layer, wherein the anti-seepage structure forms a divided space open at the top; a water inlet is formed at one side of the divided space, a water outlet is formed at the other side; the absorbent purifying module and the blockage preventive module are sequentially arranged in the divided space along the direction of flow; and the ecological planting layer is arranged above the absorbent purifying module and the blockage preventive module. The substrate structural system effectively solves the problems of single substrates and susceptibleness to blockage of conventional wet lands, improves the operating efficiency and purifying effect of the wet land, makes the most of urban organic waste and garden waste, avoids waste of resources and realizes the purpose of changing waste into treasure. The substrate structural system has the advantages of wide source of materials, low cost, simplicity of construction and conservation of construction time and cost, and due to remarkable increases in operating efficiency and durability of the substrate, the later curing cost can be greatly reduced.

Description

technical field [0001] The invention relates to the technical field of environmental treatment, in particular to a horizontal flow artificial wetland matrix structure system. The invention relates to a constructed wetland substrate and structure for purifying sewage, in particular to a constructed wetland substrate and structure that can effectively improve the problem of easy clogging of conventional constructed wetland substrates. Background technique [0002] At present, the treatment methods for sewage mainly include biological treatment methods, physical treatment methods and chemical treatment methods. Biological treatment technology can effectively remove organic matter in water, but generally the removal rate of nitrogen is not high; chemical methods can effectively remove nitrogen in sewage, but the cost is high and it is easy to cause secondary pollution. Constructed wetlands, as a low investment, low energy consumption and wastewater ecological treatment technolo...

AI Technical Summary

Problems solved by technology

[0004] However, there are three problems in the actual operation of constructed wetlands: (1) matrix clogging; (2) the limited constructed wetland matrix is ​​easy to saturate the adsorption of pollutants, and the removal effect of pollutants will decrease or even lose its function; ( 3) single matrix

After a period of operation of the constructed wetland, due to the accumulation of organic matter, the matrix is ​​prone to clogging

This will lead to a sharp drop in the permeability coefficient of the wetland substrate, a decrease in the water passing capacity, causing odor, breeding of mosquitoes and flies, deteriorating the operating environment, and reducing the removal effect of pollutants
