Simulating riverway biological respinse unit for repairing light polluted water body

Abstract

The invention discloses a simulating riverway biological respinse unit for repairing light polluted water body. A water inlet area is connected with a main riverway reaction area and a water outlet area in sequence; the upper parts of the outer walls of the two sides of the main riverway reaction area are provided with a bypass drainage area respectively; the lower parts of the outer walls of thetwo sides of the main riverway reaction area are provided with an water outlet respectively; each by-pass drainage area is provided with a plurality of motor-driven rotary brushes; the upper parts ofthe inner walls of the two sides of the main riverway reaction area are provided with a padding bracket respectively; the end part of the water inlet area is provided with a water inlet; a water distribution plate is arranged between the water inlet area and the main riverway reaction area; the connection parts of the by-pass drainage area and the two sides of the main riverway reaction area are respectively provided with a triangle river diversion module; a lower river diversion clapboard is arranged between the main riverway reaction area and the water outlet area; and the end part of the water outlet area is provided with a downflow weir and a water outlet. The invention is favor of developing the simulation study of a light polluted water body repairing process, and the study result has good amplification property and the practical operability, and can provide reliable technical support for the parameter optimization and stable operation of the light polluted water body repairing project.

Description

technical field [0001] The invention relates to a simulated river biological reaction device for repairing slightly polluted water bodies. Background technique [0002] In recent years, with the rapid development of my country's social economy and the continuous expansion of small towns, problems such as urban industrial wastewater, rural domestic sewage, domestic garbage, livestock and poultry breeding waste exceeding the standard discharge or direct discharge, and non-point source pollution of pesticides and fertilizers have become prominent, which has caused my country's Urban surface water and groundwater sources are seriously polluted and tend to intensify. Ensuring the safety of drinking water has become a major social problem to be solved urgently in our country. [0003] The existing ecological restoration research and practice have shown that the biofilm method of microbial restoration of polluted water has the characteristics of low cost, aquatic ecology friendlines...

Problems solved by technology

[0004] At the same time, micro-polluted natural water bodies often have the characteristics of variable water quality and quantity, and few available carbon sources. At present, most biological denitrification reaction devices mainly treat sewage (waste) water, and are used for the raw materials of oligotrophic water bodies. The remediation efficiency of denitrification is not high, and it is difficult to better guide the actual micro-polluted water remediation project
