Abstract

Abstract

In order to reduce the risk of ecological environment when the reclaimed water from a sewage plant is reused in the urban landscape water body, this paper took the ecological restoration section of a sewage plant in Ningbo as the research object, used the ecological integration technology to purify and repair the reclaimed water, and studied its conventional water quality index, comprehensive biological toxicity of water body and characteristics of river benthos community impact. The results showed that the ecological restoration measures had obvious effect on the stability of reclaimed water quality; the main water quality indicators remained stable and met the water quality requirements of the functional area; the toxicity of reclaimed water quality was reduced; the species richness and biological density of benthos in the river were also increased significantly, which effectively reduced the ecological risks from the replenishment of reclaimed water, had a significant impact on the flow and ecological safety of urban river water.
