Closed-loop river water environment treatment system and method

Abstract

The invention discloses a closed-loop river water environment treatment system and method. Water body in an inflow reach is lifted to heights and ejected through a discharging tube under the dynamic effect provided by a power pump, the water body firstly is in thorough contact with air and in aeration, then is ecologically purified through wetlands, ecological floating beds or the combination of the wetlands and the ecological floating beds and then overflows to an outflow reach in the form of weir flow, accordingly the mobility of the closed-loop river is enhanced, and the dissolved oxygen level and water environmental capacity of the river are improved. The flow velocity of the river is controlled by a flow control valve, the electricity of the power pump and a desilting pump is provided by the complementation of a solar cell panel, a wind driven generator and a self-providing supply under the control of a power distribution unit, pollutants of sludge and the like at the bottom of a clarifier-tank are removed regularly through the desilting pump, and accordingly the water quality of the river is improved. The closed-loop river water environment treatment system and method are low in operation cost, simple in structure, economical in investment, convenient to operate and remarkable in economic and social benefit, and have research and popularization value under the background of fast urbanization development and risks of energy and water environment.

Description

technical field [0001] The invention belongs to the field of water environment management, and in particular relates to a closed-loop river water environment management system and method. Background technique [0002] The water environment is an important part of the natural ecological environment, but with the acceleration of industrial and agricultural development and urbanization, the deterioration of the water environment has become an indisputable fact. Governments at all levels and their relevant functional departments have also put water environment improvement and restoration on their agenda, and are constantly exploring ways to improve the water environment, especially to restore the water environment of urban rivers in practice. The river network extends in all directions, and most of them are of different shapes and lengths, so it is very difficult to manage them. How to improve the water quality of these river networks, at present, the method of diverting clear ...
