Background
In recent years, due to excessive water consumption in the lake region, urban sewage treatment systems are not mature, a large amount of untreated sewage is directly discharged into the lake, after the pollutant entering the lake exceeds the self-cleaning capability of the water body, the pollutant in the water body is deposited into the bottom mud to form sediment, the sediment becomes a storage place of the pollutant in the water body, the dissolved oxygen of the water body is rapidly reduced, the water quality is deteriorated, a large amount of fish and other organisms die, and the ecological balance of the water body is seriously destroyed. In many bodies of water, particularly shallow lakes. The pollution control difficulty of the shallow lake is higher due to the reasons of weak self-cleaning capability, insufficient hydrodynamic force, easiness in resuspension and the like, and the conventional technology for controlling the endogenous pollution of the shallow lake mainly comprises sediment dredging, ecological restoration, in-situ control technology and the like. The sediment dredging causes serious damage to benthonic ecology due to high input cost, so that in-situ ecological restoration technologies based on environment-friendly physical, chemical, nutritional microbial agents and the like are more current. The initial stage of the storm is a great difficulty in constructing the lake water ecological system, and how to treat rainwater and untreated industrial sewage under the condition that the diversion of the rainwater and the sewage is not completed at the upstream, so that the influence on the lake water ecological system is reduced as much as possible, and the method is a problem to be solved urgently.
Chinese patent document CN 212532444U describes an in-situ ecological purification system suitable for large-scale lake-entering rainwater drainage, which sequentially arranges a sewage blocking net, gravel filler, artificial medium, ecological floating bed and perforated soft enclosure in radial form from the drainage end of the drainage to the water body, and the blocking barrier covers between the artificial medium and the ecological floating bed. The drainage purification system is separated from the lake water body mainly through a perforated soft enclosure to form an independent purification system, and different purification measures are arranged inside the system to realize purification and increase hydraulic retention time. The system removes various pollutants in rainwater entering rivers and lakes layer by layer through multistage purification. But the system has weak self-cleaning capability, insufficient hydrodynamic force and easy resuspension. Meanwhile, the system does not utilize the water source, so that energy is wasted. The system can not remove the sewage from the industrial sewage, can not discharge the water polluted by life and industry into the lake, has defects in use and needs improvement.
