| Summary: | 碩士 === 崑山科技大學 === 材料工程研究所 === 100 === Activated sludge process method is currently the world''s most popular urban sewage treatment, this method has many advantages, but in the process, often due to microbial growth and the output of a large number of waste activated sludge (waste activated sludge, WAS) these waste sludge, poor concentration, and the high cost of sludge treatment to conventional sludge treatment and disposal need to spend a lot of manpower and material resources, if not handled properly, it is likely to cause secondary environmental pollution, including toxic substances will a direct impact on human health and safety. Therefore, in this paper, study, screened by the dominant species from the environment and the composition of complex dominant bacteria to develop a safe, non-toxic, harmless and does not damage the ecological characteristics of the sludge of biological agents, and then vote added to the sewage processing system for processing, research water COD, SCOD, SS, VSS, etc., of biological agents for sludge treatment effect reduce the amount of sludge, while the value of changes after treatment, the results confirmed that in the first 5 days sludge reduction rate of 34.3%, can effectively reduce the amount of sludge.
