River ecological restoration method

Abstract

The invention relates to the field of river regulation, in particular to a river ecological restoration method. The method comprises the following steps: step 1, performing partition treatment; step 2, dredging and salvaging floating objects by adopting a physical treatment method; step 3, laying aeration and oxygenation equipment; step 4, putting microorganisms; step 5, putting a biological agent; 6, cultivating submerged plants, wherein the submerged plants are cultivated through a seedling throwing method or a cuttage method; and step 7, constructing an artificial ecological floating island. According to the ecological restoration method for the riverway, the riverway to be treated is divided into sections and regions, then a physical treatment method is utilized, aeration and oxygenation equipment is laid, microorganisms and biological agents are put, submerged plants are cultivated, and an artificial ecological floating island is constructed, so that the restoration rate of a eutrophic riverway water body is increased, and the problem of river water quality can be thoroughly solved.

Description

technical field [0001] The invention relates to the field of river management, in particular to a river ecological restoration method. Background technique [0002] River channel pollution is a common form of water pollution, and polluted river channels usually cause black odor due to microbial enrichment and excessive pollutants. The ecosystem in the black and odorous river course has long been destroyed, and natural purification cannot be carried out, thus causing the water body to continue to deteriorate. This not only affects the landscape along the river, causing serious visual pollution, but also has a negative effect on the local economic development and the creation of the ecological environment in the area, which needs to be dealt with urgently. [0003] Traditional river management usually uses methods such as sediment dredging, hardening of the river bed, building stones, and concrete slope protection. However, such methods can only curb the further deterioration...

AI Technical Summary

Problems solved by technology

The ecosystem in the black and smelly river has been destroyed long ago, and natural purification cannot be carried out, thus causing the water body to continue to deteriorate

This not only affects the landscape along the river, causing serious visual pollution, but also has a negative effect on the local economic development and the creation of the ecological environment in the area, which needs to be treated urgently

[0003] Traditional river management usually uses methods such as sediment dredging, hardening of the river bed, building stones, concrete slope protection, etc. However, such methods can only curb the further deterioration of eutrophic river water quality, but cannot completely solve the river water quality problem
