Modularized percolation dam assembly for river regulation

Abstract

The invention relates to the technical field of river regulation, in particular to a modular percolation dam assembly for river regulation, which comprehensively treats a river water body through continuously arranged anaerobic modules and aerobic modules. A plurality of water baffle plates which are opened alternately up and down are continuously arranged in the anaerobic module to form a baffling path which reciprocates up and down, and fillers are fully distributed in the baffling path, so that the effective retention time of a water body in the anaerobic module and the sufficient reaction time of the water body and the fillers are prolonged, and the hydraulic flow path and the hydraulic time are prolonged; according to the modularized percolation dam assembly disclosed by the invention, the anaerobic module does not need energy consumption, sludge is basically not generated, and meanwhile, a river water body and the biological filler can be fully contacted and reacted, so that pollutants are reduced to the greatest extent. The filler is high in cost performance and low in replacement cost, the manufacturing, production and installation processes of the modular percolation dam body assembly are simple, and the B / C ratio, namely BOD / COD, of water quality does not need to be considered in river regulation and represents biodegradability.

Description

technical field [0001] The invention relates to the technical field of river channel regulation, in particular to a modular seepage dam assembly for river channel regulation. Background technique [0002] At present, there are physical, chemical, biological, and recently popular biological-ecological methods for the treatment of black and odorous water channels at home and abroad. Physical technologies mainly include sewage interception and dredging, water diversion, aeration and oxygenation, etc. Physical methods Because the riverbed of the treated river has been deepened, the removal of heavily polluted silt has played a certain role in reducing the odor of the river. In addition, cutting bends and straightening can enhance the ability of the river to wash away pollution. However, physical methods often have good short-term effects, and it is difficult to maintain long-term water ecological environment effects, and the cost is relatively high, and they are also easily rest...
