An anti-clogging constructed wetland system applied to domestic sewage and low-pollution water

Abstract

The invention discloses an anti-clogging constructed wetland system for domestic sewage and low pollution water. The anti-clogging constructed wetland system comprises a water distribution pond, a treatment device, a rotating device and a water discharge tank. The treatment device clings to the water distribution pond and the water discharge tank and is arranged between the water distribution pond and the water discharge tank. Sewage enters the water distribution pond, is physically precipitated and then enters the treatment device, the contaminants in the treatment unit are subjected to filler adsorption, microbial degradation and plant absorption, and then the purified water enters the water discharge tank and is discharged and used. The treatment device is linked to the rotating device. The rotating device drives the treatment device to rotate around a middle shaft so that blocking prevention and dredging are realized. Sewage orderly passes through the water distribution pond, the treatment device and the water discharge tank. The system is an environmentally friendly integrated wetland processing system, effectively prevents and deals with wetland blockage, has a simple structure, is easy to use and easily realizes production, installation, upgrading and replacement.

Description

technical field [0001] The invention relates to an anti-clogging artificial wetland system applied to domestic sewage and low-pollution water. Background technique [0002] Constructed wetland is a sewage treatment system artificially designed with high environmental value. It is mainly composed of fillers, plants and microorganisms. It has the advantages of ecology, landscape, low cost, and no secondary pollution. Since our country has a large population and produces a large amount of sewage, it is of great significance to reduce the cost of sewage treatment. At the same time, for the effluent of the sewage plant, using the wetland system for advanced treatment will help reduce the pollution load of the river and help the natural restoration of the river. [0003] However, since the artificial wetland mainly relies on the microbial film growing on the filler and the plant rhizomes to continuously reproduce and metabolize to treat sewage, it will inevitably produce some met...

Problems solved by technology

These methods usually require the layout of complex pipe networks and expensive equipment

Blockages contain a part of degradable pollutants, and because blockages generally occur in the upper layer of wetland water, wetlands also have a large residual capacity to hold pollutants, so it is "wasteful" to directly use physical methods to remove blockages
