Ecological water supplementing system and method for rain-source river

Abstract

The invention provides an ecological water supplementing system and method for a rain-source river. The ecological water supplementing system comprises a water plant water taking system, a water supplementing pipeline system, a water supplementing comprehensive utilization system and a rainwater storage system. The water plant water taking system comprises an overflow well water outlet system and a gate well water outlet system which are arranged in parallel. The water supplementing comprehensive utilization system has four water utilization modes and comprises a riverway upstream water supplementing opening, an artificial wetland, a small lake pond and a reserved later-period water supplementing connector. The artificial wetland and the small lake pond are finally connected to a riverway through pipelines. A water supplementing pipe network and the small lake pond are provided with reserved later-period water supplementing connectors respectively. The water supplementing pipeline system water outlet pipe network is arranged in the mode that an annular pipeline is formed by a main system, and branch systems flow into outlets through branch pipe networks. The rainwater storage system comprises a rainwater storage module. Rainwater flows through a mud settling and flow abandoning well to the rainwater storage module. By means of the technical scheme, water supplementing of a drainage basin can be achieved, and the effects that flowing water of the drainage basin is abundant and water is clear and reaches the standard can be improved according to different situations.

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 watershed has changed from clear to turbid. Among them, the rain source river plays an indispensable role in the urban development. The flow of the rain source river mainly comes from rainfall, the environmental capacity is small, the hydropower is insufficient, and it is self-purifying. The ability is poor, and it is easy to cause black and smelly watersheds, causing watershed pollution problems. As the country attaches great importance to the ecological environment, river basin governance has become an indispensable part, including solving problems such as the lack of base flow and water quality in the river basin. In the case of scarcity of water resources, most water sources such as reservoirs are currently used 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.
