Study on Urban Wastewater Treatment and Environmental Protection in Hefei

Abstract

City is the mirror of social civilization, and the rapid development of city not only provides a good material life for people, but also can fundamentally influence the development of people's thoughts. But every coin has two sides: with the rapid economic development, it has also brought a lot of trouble for environmental protection. As we know, environment is the most basic factors we human depend on for living, and the development of the city should fully consider the problem of environmental protection. With the development of society and economy, the environment problem has become the restriction of social development. Especially the urban sewage emissions have seriously hindered the urban construction of environmental protection, which has become the common concern of research and application of water treatment technologies. It requires that sewage treatment should not only meet the water quality improvement, at the same time but also need to consider the problem of resource recycling and energy regeneration of pollutants and sewage. The technology must be used on the premise of low energy consumption and less resource depletion
