Lake-entering river channel water purifying and water resource recycling system

Abstract

The invention discloses a lake-entering river channel water purifying and water resource recycling system. The lake-entering river channel water purifying and water resource recycling system comprisesa converging zone, an ecological regulating and storing zone and a lakeside zone which are sequentially communicated with one another, wherein the converging zone is used for converging producing anddomestic wastewater, subsiding water in a farmland operation area and a surface source runoff in a farmland and introducing the converged wastewater into the ecological regulating and storing zone; the ecological regulating and storing zone is arranged between the converging zone and the lakeside zone, and according to positions of main river channels and ditches in the zone, a plurality of waterdividing ports are formed in the length direction of the ecological regulating and storing zone at intervals; the ecological regulating and storing zone comprises an intercepting subsystem, a purifying subsystem and a regulating and storing and recycling subsystem; the intercepting subsystem is used for intercepting silt and impurities in the introduced wastewater; the purifying subsystem comprises a submerged wetland; the submerged wetland is communicated with the intercepting subsystem, and is used for deeply purifying pollutants in the wastewater; the regulating and storing and recycling subsystem introduces the purely purified water resource in the purifying subsystem into the lakeside zone for supplementing water and recycles the water resource in a water using area respectively.

Description

technical field [0001] The invention belongs to the technical field of lake water pollution control and water ecological restoration, and specifically relates to a system for water quality purification and water resource reuse of rivers entering a lake. Background technique [0002] Due to the influence of factors such as location relationship, hydrodynamic conditions, urban non-point sources and agricultural non-point sources are difficult to control, lake water pollution control and water ecological restoration have become problems that are universally concerned and strived to be overcome, especially in areas with water shortages. Lakes, while giving full play to their functions of regulation and storage, irrigation, landscape, ecology and climate regulation, also bear the burden of rapid regional economic and social development, resulting in serious pollution of river water, eutrophication of lake water, and further Restrict the sustainable development of regional economi...
