Abstract

The invention discloses a stabilization ponds-ecological corridors-constructed wetland based tail water treatment system, and belongs to the technical field of sewage treatment. The system comprises stabilization ponds (an aerated pond, a facultative pond and an aerobic pond), ecological corridors (1#, 2# and 3#) and a surface flow wetland; and tail water for treatment sequentially goes through the aerated pond, the 1# ecological corridor, the facultative pond, the 2# ecological corridor, the surface flow wetland, the 3# ecological corridor and the aerobic pond, and is discharged. The system uses biological treatment as a main means, is based on the theoretic research on the removal of pollutants through the aerated pond, a trench wetland and the constructed wetland, follows the conversion rule of main pollutants in tail water, optimally combines different types of the stabilization ponds with the constructed wetland, and utilizes the ecological corridors modeled on the trench wetland as a water conveying trench to form a tandem type aerobic-anaerobic reactor in order to promote the effective removal of the pollutants in the tail water.

Description

technical field [0001] The invention relates to a tail water treatment system based on a stabilization pond-ecological corridor-artificial wetland, and belongs to the technical field of sewage treatment. Background technique [0002] With the growth of population and the rapid development of social economy, the discharge of industrial wastewater and domestic sewage is increasing day by day. In order to ensure the coordinated development of economic construction and environmental protection, a large number of sewage treatment plants have been built in various places to conduct centralized treatment of sewage and wastewater. Water is generally discharged directly into the body of water. The construction and operation of sewage treatment plants have reduced the pollution load of surface water to a certain extent, and effectively guaranteed the environmental quality and function of surface water. However, based on the fact that most of the sewage treatment plants implement the ...
