- 摘要:
- 结合北京市污水处理情况，调研了北京市污泥处理工艺、规模及处理处置现状。目前北京市建设的污泥处理项目基本满足全市污水厂产生污泥的处理需求，也达到了“十三五”生态环境保护规划的要求；北京市污泥处理方式中心城区以厌氧消化为主，周边区域以好氧发酵为主、其他多种工艺为辅；处置方式以土地利用为主、建材利用为辅。通过对当前北京市污泥处理处置现状分析，结合国内外污泥处理处置情况以及国内主流污泥处理处置工艺路线特点及适用情况分析，对北京市污泥处理路线与国家相关指引技术指南的匹配度、工艺应用普及推广可能性进行分析，并对北京市污泥的处理能力、处理成本及处置出路情况进行了分析总结，以期为我国其他城市污泥处理处置工艺的选择提供一定的参考和借鉴。
- Abstract:
- The situations of sewage sludge treatment in Beijing including the technologies, the scales and state-of-the-art in this field were investigated, combined with the sewage treatment situation. The sludge treatment projects in Beijing basically met the treatment needs of sludge from municipal sewage plants among the whole city, which also fit the requirements of the “13th-five Year Plan” ecological environmental protection plan. Anaerobic digestion was the main sludge treatment in the central urban area of Beijing.Meanwhile, in the surrounding area of Beijing, the sludge was mainly treated by aerobic fermentation, which may be assisted by other processes. The disposal is mainly processed by land utilization, and the use of construction materials could also be a solution. This paper analyzes the current situations of sludge treatment and disposal in Beijing, the situations of sludge treatment and disposal at home and abroad, and the characteristics of domestic mainstream sludge treatment and disposal process. We also analyzed the matching degree between the sludge treatment route in Beijing and the relevant national technical guidelines, and the possibility of popularization and promotion of process application. Furthermore, this work analyzes and summarizes the sludge treatment capacity, treatment cost and disposal outlet in Beijing. This work could provide a certain reference for other cities on the selection of sludge treatment and disposal strategies in China.
