Abstract

The invention discloses a constructed wetland-based sewage treatment system, which comprises four treatment units, each treatment unit comprises a pool body, a plurality of partition plates, a drain pipe and a back-flushing pipe, the partition plates are arranged in the pool body in parallel from top to bottom, the bottom wall of the pool body is inclined downwards along the water flow direction, the drain pipe is communicated with the pool body, and the back-flushing pipe is communicated with the bottom wall of the pool body. A first valve is arranged on the drain pipe, the backflushing pipe is communicated with the drain pipe between the tank body and the first valve, and a second valve is arranged on the backflushing pipe. Multiple treatment units are adopted, the sewage treatment efficiency and the purification degree are greatly improved, a backflushing structure is arranged, and the problems of drainage blockage and the like can be conveniently solved.

Description

technical field [0001] The invention relates to the field of sewage treatment, in particular to a sewage treatment system based on artificial wetlands. Background technique [0002] Constructed wetland is a controlled distribution of sewage and sludge to the artificially constructed wetland. During the flow of sewage and sludge in a certain direction, the physical, chemical and biological triplets of soil, artificial medium, plants and microorganisms are used to Synergistic effect, a technology for treating sewage and sludge. In the prior art, the sewage treatment efficiency of a separate constructed wetland is low, and the degree of purification after treatment is poor, and its drainage system is prone to blockage, and its maintenance is cumbersome. Contents of the invention [0003] In order to overcome the deficiencies of the prior art, the purpose of the present invention is to provide a sewage treatment system based on constructed wetlands, which adopts multiple trea...
