Constructed wetland with blocking resistance and enhanced decontamination

Abstract

The invention discloses a constructed wetland with blocking resistance and enhanced decontamination. The constructed wetland with blocking resistance and enhanced decontamination comprises a main bodyarea filled with a wetland substrate, a wetland plant system, constructed wetland walls, a water inlet and a water outlet, wherein the main body area is divided into wetland substrate enhancement areas provided with wetland enhanced substrates, and the wetland enhanced substrates are fixed to the interiors of wetland enhanced substrate shells; the wetland plant system is planted in a surface layer of the wetland substrate; the constructed wetland walls are used for defining the main body area; and the water inlet and the water outlet are formed in opposite two side wall surfaces of the constructed wetland walls respectively. According to the constructed wetland with blocking resistance and enhanced decontamination, by arranging novel modules and novel modified filler in a traditional constructed wetland system, through combined arrangement of the filler, decontamination is enhanced, blocking is relived, and meanwhile, through modular construction and treatment and simplification of operation and management, the constructed wetland with blocking resistance and enhanced decontamination has outstanding practicability and wide popularization values.

Description

technical field [0001] The invention relates to the technical field of constructed wetlands, in particular to a constructed wetland with anti-clogging and enhanced decontamination. Background technique [0002] Constructed wetlands are more and more used in the fields of advanced treatment of tail water of sewage treatment plants, ecological restoration of rivers and lakes, and non-point source pollution control due to their advantages of good effluent quality, low consumption and high efficiency, and landscape effects. In terms of standardization of rural domestic sewage treatment facilities, more and more places tend to adopt artificial wetland technology, which greatly promotes the promotion and application of this technology. [0003] However, constructed wetlands also have problems such as unstable treatment efficiency and easy clogging, which limit their further promotion and development. It is necessary to optimize and improve their structure, filling and filling layo...
