Black and odorous river regulating and recovering method

Abstract

The invention discloses a black and odorous river regulating and recovering method which includes the following steps that firstly, dirt stopping and discharging of a river are performed; secondly, desilting of the river is performed; thirdly, paying-off is measured; fourthly, slope surface finishing is performed; fifthly, a plant pad is paved; sixthly, irrigation is performed; seventhly, the river is managed and maintained by manual work for one year. The black and odorous river regulating and recovering method can effectively regulates the conditions that the river is black and odorous and a water body is deteriorated, the quality of water is purified fundamentally, and a novel water body ecological system is formed. In addition, the water body can have self-growing and self-purifying capacities, and the water body can reach the standards of water of the fourth kind. Meanwhile, stability of slope bodies of the two sides of the river and conservation of water and soil are achieved, the environment is effectively renovated, after manual management and maintenance are removed, the functions of the black and odorous river regulating and recovering method can be continued, the functions of discharging dirt, preventing flood, ensuring navigation, draining flood and the like are not affected, and greening and beautifying of the urban landscape can also be effectively enhanced.

Description

technical field [0001] The invention relates to a black and odorous river course treatment and recovery method, belonging to the technical field of river course treatment. Background technique [0002] For rivers with severe black and odor, due to years of siltation, the indirect (direct) inflow of domestic sewage and a small amount of industrial wastewater caused revetment erosion, collapse and messy growth of plants, which was devastated, not only affecting the landscape along the road , causing serious visual pollution, there are also hidden dangers of germ hygiene, and at the same time it is very inconsistent with the clean surrounding environment. In addition, if the water quality of the river has no plant purification function, the water body will be in a bad state, which will have a negative effect on the local economic development in the area, the improvement of the people's living quality and living standards, and the creation of the ecological environment in the fu...

[0002] For rivers with severe black and odor, due to years of siltation, the indirect (direct) inflow of domestic sewage and a small amount of industrial wastewater caused revetment erosion, collapse and messy growth of plants, which was devastated and not only affected the landscape along the road , causing serious visual pollution, there are also hidden dangers of germ hygiene, and at the same time it is very inconsistent with the clean surrounding environment

In addition, if the water quality of the river has no plant purification function, the water body will be in a bad state, which will have a negative effect on the local economic development in the area, the improvement of the people's living quality and living standards, and the creation of an ecological environment in the future. The protection of the environment, the development, utilization and development of resources have caused negative effects
