Ecological molecular fluid restoration method for deep pools and shoals in basins

Abstract

The invention relates to an ecological molecular fluid restoration method for deep pools and shoals in basins. The molecular fluid restoration method includes deep pool restoration, slope restorationand shoal restoration. Before implementation of ecological restorations of the deep pools and the shoals, the deep pools and the shoals are selected according to following conditions: 1, whether a deep pool exists in the basin or not; 2, whether a shoal exists in the basin or not. Total amount of pollutant reduced by deep pool restoration is represented by sludge reduction mainly realized by a high dissolved oxygen technology, a microorganism dispelling technology, an ecological factor controlling technology and a sludge reduction technology; water and soil stabilization in slope restoration is mainly realized by paving ecological slope protection bricks and planting waterlogging resistant plants; ecosystem construction in shoal restoration mainly includes plant ecosystem construction, microorganism ecosystem construction and animal ecosystem construction. The molecular fluid restoration method has the advantages that healthy and ordered development of the microorganism ecosystem is realized, and water body pollutants are degraded effectively.

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...

AI Technical Summary

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
