Abstract

The invention belongs to the technical field of subsurface flow wetlands, and provides an anti-blocking structure used for a subsurface flow wetland and the subsurface flow wetland. The technical solution is that a porous cylinder is horizontally fixed between the walls of a purification tank and passes through a water-permeable filler; a threaded rod and a rotating impeller are installed in the porous cylinder, and the threaded rod is installed between the walls of the purification tank and can drive the rotating impeller to rotate around the central axis of the porous cylinder; the filler inthe cylinder fills the space between the porous cylinder and the rotating impeller, one end of the threaded rod passes through the tank wall to be connected with an electromotor; the tank wall located at the other end of the threaded rod is provided with a material outlet of the porous cylinder; the exterior of the material outlet is provided with a filler recovery basket; and one end of a multifunctional pipe communicates with a cylinder body of the porous cylinder, and the other end passes through the ground of the subsurface flow wetland. The subsurface flow wetland includes the above anti-blocking structure. The structure provided by the invention solves the problem that the filler blocks the purification tank in the wetland, and is simple and easy to operate, and convenient for replacement and washing of the filler.

Description

technical field [0001] The invention relates to the technical field of subsurface flow wetlands, in particular to an anti-clogging structure of subsurface flow wetlands and a subsurface flow wetland with the structure. Background technique [0002] The water body of the subsurface wetland flows inside the wetland bed, and the purification effect is remarkable by using the biofilm, plant root system and microorganisms on the surface of the filler, and the construction in the underground has a good thermal insulation effect, which overcomes the unstable purification of the surface flow wetland in winter and the large footprint , The disadvantage of low purification effect. In the prior art, a subsurface wetland includes a water distribution system, a purification system and a drainage system. The water distribution system includes a water inlet pipe, a valve on the water inlet pipe, a water distribution well, a water distribution flower wall with a water distribution hole, an...
