Tidal waterway gate pump dispatching method and ecological restoration for tidal waterway

Abstract

The invention discloses a tidal waterway gate pump dispatching method and an ecological restoration for a tidal waterway. The tidal waterway gate pump dispatching method comprises the steps that in the waterway dry season, a gate of a river mouth is closed; in the waterway flood period, when the tide is located at the low tide level, the gate of the river mouth is opened, flood is discharged into the sea, and water flows into the sea in one direction; and in the waterway flood period, when the tide is located at the high tide level, the gate of the river mouth is closed, the flood is discharged into the sea through a pump station, and the water flows into the sea in one direction. According to the tidal waterway gate pump dispatching method, the water gate, the pump station and other water conservancy facilities in the river network area are utilized, the water conservancy facilities are combined with regulation and control measures, reciprocating flow is changed into one-way flow, it is guaranteed that the upstream water body of the waterway is not jacked by the tide, and the discharging speed is increased; meanwhile, the dilution and self-cleaning functions of the water body are improved, the virtuous cycle is formed, the problem that the tidal river network is subjected to dual actions of tide and runoff, and pollutants flow in the river network area in a reciprocating manner is solved, and meanwhile the effect of tidal river section ecological restoration is improved.

Description

technical field [0001] The invention relates to the technical field of ecological restoration, in particular to a tidal river sluice pump scheduling method for ecological restoration and an ecological restoration method for tidal rivers. Background technique [0002] Some tidal river networks, such as the Pearl River Delta river network area, are affected by the dual effects of tidal currents and runoff. Pollutants flow back and forth in the river network area and stay for a long time, making the degradation of pollutants unable to keep up with discharge, resulting in the accumulation of pollutants. The dissolved oxygen in the water body is consumed, forming a vicious circle. Contents of the invention [0003] The technical problem to be solved by the present invention is to provide a tidal river sluice pump scheduling method and a tidal river ecological restoration method that can improve the ecological restoration effect of the river and effectively improve the water env...
