Abstract

The invention discloses a spiral composite constructed wetland system which comprises a main support body and a spiral stepped support frame arranged on the main support body, and the spiral stepped support frame is provided with a plurality of constructed wetland reactors connected in series from top to bottom in space; each constructed wetland reactor comprises a subsurface flow constructed wetland and a surface flow constructed wetland. According to the invention, on the basis of efficiently purifying sewage, the space utilization rate is increased, the land is saved, meanwhile, an environment beautifying function is achieved, and positive significance is generated for construction of constructed wetlands under the condition of land shortage.

Description

technical field [0001] The invention relates to a spiral composite constructed wetland system, in particular to a novel spiral composite constructed wetland system which makes full use of space, and belongs to the technical field of sewage treatment. Background technique [0002] At present, my country's wastewater treatment mainly relies on sewage treatment plants, which have high operating costs and complex management and operation. Constructed wetland is an engineered wetland system that simulates natural wetlands and uses soil, substrate, plants and microorganisms to purify sewage. It can treat almost all types of wastewater, such as domestic sewage, rainwater runoff, agricultural runoff, industrial discharge and polluted water. river water etc. In addition to the function of wastewater treatment, artificial wetlands also have good landscape functions, ecological protection, water resource reuse, regional climate regulation, and educational and recreational uses.
