Abstract

The invention relates to the field of constructed wetlands. The invention discloses a backwashing system and a backwashing method of an artificial wetland. The constructed wetland is arranged in the water tank; the constructed wetland comprises a filler layer (10) and a surface layer (20) located above the filler layer; the backwashing system comprises a pressure water supply mechanism (30), a perforated water collecting pipe (40) and a connecting pipe group, wherein the perforated water collecting pipe (40) is arranged in the packing layer (10); the connecting pipe set is used for connectingthe pressure water supply mechanism (30) and the perforated water collecting pipe (40), so that the pressure water supply mechanism (30) can flush the perforated water collecting pipe (40). The backwashing system provided by the invention can effectively solve the problem of clogging of the perforated water collecting pipe.

Description

technical field [0001] The invention relates to the field of artificial wetlands, in particular to a backwashing system and a backwashing method for artificial wetlands. Background technique [0002] Constructed wetland is a kind of artificially constructed and controlled sewage ecological treatment technology developed on the basis of sewage treatment technologies such as land treatment systems, stabilization ponds, and biological filters. Compared with the conventional sewage treatment process, the constructed wetland has the remarkable characteristics of good treatment effect, strong nitrogen and phosphorus removal capacity, convenient operation and maintenance management, low engineering infrastructure and operation costs, but there is also the problem that the constructed wetland packing bed is easy to silt up; The drainage structure of the common constructed wetland system at present, when the constructed wetland system, especially the terminal perforated pipe drainage...
