Research on the Value of Sludge Resource Utilization in A Sewage Treatment Plant in A Certain City in Southwest China

Abstract

With the acceleration of urbanization and the improvement of living standards, environmental issues are receiving increasing attention. In recent years, the National Development and Reform Commission and other three departments have issued the "Implementation Plan for Harmless Treatment and Resource Utilization of Sludge", proposing to implement harmless treatment of sludge and promote resource utilization, which is an important measure to build a beautiful China. In order to prevent water pollution and improve environmental quality, the sewage treatment capacity in the Southwest region has rapidly increased, and the sludge production has also sharply increased. The sludge contains various organic pollutants and nutrients, and the resource utilization of sludge has attracted people's attention. Analyzing the properties and nutrients of sludge is a prerequisite for scientific and reasonable sludge resource utilization. Therefore, this article takes sewage treatment plant sludge as the research object, conducts in-depth research on sludge properties and nutrients, and conducts in-depth research on the resource utilization value of sludge.
