Status Quo and Resource Utilization Technology of Sludge Treatment and Disposal

With the development of China's economy and the improvement of people's quality of life, the per capita sewage output has increased, resulting in an increase in the treatment load of the sewage plant, which in turn will increase the sludge output of the sewage plant. Sludge contains a large number of recyclable substances, at present, China's sludge treatment and disposal technology, has not been completely completed the stabilization treatment, it is difficult to talk about the resource utilization of sludge. Moreover, there is a serious phenomenon of "heavy water and light mud" in China, with high treatment costs, imperfect treatment technology, and low resource utilization. This paper expounds the treatment effect of China's current treatment and disposal technology, analyzes the development trend of sludge treatment technology, improves the utilization rate of sludge resources and reduces treatment costs.
