环境友好型通沟污泥处理工程实践
- Title:
- Practice of Environment-friendly Sewer Sludge Treatment Project
- 摘要:
- 上海市金山区通沟污泥处理工程借鉴上海市其他通沟污泥处理站的运行经验,针对超细砂(粒径<0.2 mm)含量高且难分离的特性,确定了水力旋筛+砂石分离工艺,对污泥进行分级分离,取得了良好的效果。将通沟污泥分离为粗大物质、矿化物质、有机栅渣和超细砂,并实现资源化利用。工程采用生物除臭系统,除臭效果满足《城镇污水处理厂污染物排放标准》(GB 18918—2002)废气排放厂界一级排放标准和上海市地方标准《城镇污水处理厂大气污染物排放标准》(DB 31/982—2016)。
- 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).
