- Abstract:
- The sewer sludge treatment project in Jinshan District, Shanghai draws lessons from the operational experience of other sewer sludge treatment stations in Shanghai. In view of the characteristics of high content of ultra-fine sand (particle size less than 0.2 mm) and difficulty in separation, the hydraulic rotary screen and sand/gravel separation process is determined to separate the sludge, and good performance is achieved. The sewer sludge is separated into coarse material, mineralized material, organic grate slag and ultra-fine sand, and the resource utilization is realized. The biological deodorization system is adopted in the project, and the deodorization performance meets the first level emission limit at plant boundary specified in Discharge Standard of Pollutants for Municipal Wastewater Treatment Plant (GB 18918-2002) and the Shanghai local Emission Standard of Air Pollutants for Urban Wastewater Treatment Plant (DB 31/982-2016).
