Urban Sewage Treatment and Ecological Environment Protection Strategy
With the continuous acceleration of the urbanization process,the problem of urban environmental pollution has gradually become prominent,and urban sewage treatment has become an important topic of environmental protection and sustainable development.Urban sewage contains a lot of harmful substances such as organic matter,nutrients and heavy metals.If it is discharged directly without treatment,it will cause damage to the water,soil and ecosystem.Ecological environmental protection emphasizes ecosystem protection and restoration,based on natural ecological processes,and realizes sewage purification by building a self-sufficient,self-cleaning and self-healing ecosystem.This paper aims to discuss the sewage treatment strategy of urban environmental engineering based on the concept of ecological environmental protection,and provide useful reference for the governance of urban environmental work.
