A Method for Ecological Restoration of Molecular Fluids in Deep Pools and Shoals in Watersheds

Abstract

The invention relates to a method for ecological restoration of molecular fluids in deep pools and shoals in watersheds. It mainly consists of three restoration methods: deep pools, slopes and shoals. Before carrying out the ecological restoration of deep pools and shoals, the following conditions should be selected: Condition 1: whether there are deep pools in the watershed; condition 2: whether there are shoals in the watershed; The reduction of the total amount of pollutants in the deep pool restoration is mainly achieved through the reduction of sludge in the watershed through high dissolved oxygen technology, microbial digestion technology, ecological factor regulation technology and sludge reduction technology; The soil and water stabilization in slope restoration is mainly achieved by laying ecological slope protection bricks and planting water-resistant and wet plants; the ecosystem construction in the shoal restoration is mainly through the construction of plant ecosystems and microbial ecosystems And construct the animal ecosystem to realize the construction of the ecosystem. Realize the healthy and orderly development of the microbial ecosystem and effectively degrade water pollutants.

Description

technical field [0001] The invention relates to a technique for restoring deep pools and shallows, in particular to a method for ecological restoration of molecular fluids in deep pools and shallows in watersheds. Background technique [0002] The standard discharge concentration of most of the discharged wastewater such as aquaculture wastewater, domestic sewage, and industrial wastewater in the basin is higher than the surface water environmental quality standard, and some of the standard discharge concentration is more than ten times or even hundreds of times higher than the surface water environmental quality standard. Therefore, As a result, the concentration of nutrients in the watershed has greatly increased. In order to make the watershed meet the environmental quality standards of surface water, the watershed needs to have a high pollution self-purification ability. Using deep pools and shoals in the watershed is a feasible method to improve the self-purification abi...

Problems solved by technology

At present, the use of deep pools and shoals mainly lies in the construction of deep pools and shoals. Since the restoration of deep pools and shoals to the ecosystem is a slow and long process, for water bodies that are seriously polluted and require short-term restoration, only the construction of deep pools and shoals Shoals cannot have a good repair effect, and in the case of poor water quality, the construction of deep pools will cause anaerobic bottom of the deep pools, lower oxidation-reduction potential, sedimentation and sediment release a large amount of pollutants, and the contents of ammonia nitrogen, total phosphorus and other indicators in the water body will increase significantly. increase, it will not only fail to restore the water body, but will also make the water body pollution more serious
