Ecological water replenishment system and water replenishment method for rain-sourced rivers

Abstract

The invention provides an ecological water replenishment system and a water replenishment method for a rain-source river, comprising a water intake system in a water plant, a water replenishment pipeline system, a comprehensive utilization system for replenishment water and a rainwater storage system. The water intake system of the water plant includes a parallel overflow well water outlet system and a gate well water outlet system; the comprehensive water replenishment utilization system includes four water utilization methods, including water replenishment ports in the upper reaches of the river, artificial wetlands, small lakes and ponds, and reserved later water replenishment interfaces. The final outlet water from the constructed wetland and small lakes and ponds is connected to the river through pipelines, and the water replenishment pipe network and small lakes and ponds respectively have reserved water replenishment interfaces for the later stage. The outlet pipe network of the water replenishment pipe system adopts the layout method that the main system forms a ring pipe, and the branch system adopts a branch pipe network to flow into each outlet. The rainwater storage system includes a rainwater storage module, and the rainwater flows through the sedimentation and abandonment well to the rainwater storage module. The technical solution of the present invention can not only realize water replenishment in the basin, but also improve the abundance of running water in the basin and the clear water quality up to the standard according to different situations. Effect.

Description

technical field [0001] The invention relates to the field of river water environment management, in particular to an ecological water replenishment system for rain-sourced rivers. Background technique [0002] With the intensified development of the city, the river basin has changed from clear to turbid. Among them, rain source rivers play an indispensable role in urban development. The flow of rain source rivers mainly comes from rainfall, with small environmental capacity, insufficient hydrodynamic force, and self-purification. The ability is poor, and it is easy to cause the black and odor of the watershed, causing the pollution of the watershed. As the country attaches great importance to the ecological environment, river basin governance has become an indispensable part, including solving problems such as lack of base flow and water quality in the basin. In the case of water scarcity, most of the current water sources such as reservoirs are used to supplement water to ...

Problems solved by technology

However, this method can only achieve recycling, and it is difficult to achieve the effect of water quality improvement and sewage treatment, which closes the biological channel and destroys the ecological river.
