Method for ecological restoration and water quality conservation of river water

Abstract

The invention discloses a method for ecological restoration and water quality conservation of river water. according to the method, an aeration oxygenation system consists of a solar cell panel, a support connector, an air pump, an aeration tube and an air distribution plate and is used for maintaining the dissolved oxygen level in the water; an ecological floating bed system consists of a strong buoyancy carrier and an emergent aquatic plant and is used for removing pollutants out of water and gathering and transferring heavy metal; and a filler system is used for providing a lot of adhesion habitats for microbial flora, phytoplankton, protozoon and tiny metazoan so as to co-build and form a biological membrane which efficiently and quickly purifies the pollutants. By adopting the method, the organic matters such as COD, nitrogen, phosphorus and the like, and other pollutants in the water can be efficiently removed, the water is purified, an ecological system of the river way is improved, and the self-cleaning capacity of the water is restored.

Description

technical field [0001] The invention relates to urban river water pollution control, in particular to a method for river water ecological restoration and water quality maintenance. Background technique [0002] As an important carrier of resources and environment, urban rivers are related to the survival of the city, restrict the development of the city, and are the source of life of the city. Urban rivers can improve the ecological environment of the city, adjust the climate, shape the urban landscape, provide residents with a better living space, promote investment, promote the vigorous development of related industries, and drive the overall progress of the city. It can be seen that urban rivers play a very important role in the development, construction and ecological environment of cities. However, with the development of the economy and society, the pollution of urban rivers is gradually increasing, and due to long-term neglect of management, the phenomenon of dirty, ...

AI Technical Summary

Problems solved by technology

However, these methods have certain limitations and deficiencies: they are mainly aimed at black and odorous water bodies containing industrial wastewater, and their application range is narrow; the application of biological filter technology in rivers is not convenient for controlling the influent flow rate, backwashing and other operations, which hinders the operation of rivers. Flood function; simple aeration and oxygenation in the river channel, the effect is not obvious, the effect is slow, and it is not conducive to the beauty of the river channel; the types of microorganisms accumulated on the plant roots are not rich enough, and the number is not large enough, so the treatment effect on the seriously polluted river channel bad

[0004] To sum up, the ecological treatment of urban rivers lacks a comprehensive treatment method with a wide range of applications and easy operation.
