摘要
根据国家海绵城市建设倡导的城市水资源就地收集处理回用的建设思想,越来越多的污水厂可能会坐落于城市中心,地埋式污水厂也将逐渐增多,因此地下污水厂的污泥处理设施面临较高的环境压力及高额的土建费用等问题。以广州市为例,对不同污泥处理及输送方式进行了技术经济分析,并介绍了国外污泥输送案例,认为城市中心地区的地下污水厂污泥宜采用管道输送方式外送并集中处理处置,在一定规模及范围内具有明显的经济技术优势。
According to the sponge city concept of local collection, treatment and reuse of urban water resources advocated by the national government, more and more wastewater treatment plants may be located in the city center, and the number of underground wastewater treatment plants will gradually in- crease. Therefore, the sludge treatment facilities of underground wastewater treatment plant are faced with high environmental pressure and high cost of civil construction, etc. Taking Guangzhou as an example, the technical and economic analysis of different sludge treatment and transportation methods was carried out, and the cases of sludge transport abroad were introduced. It is considered that underground sewage sludge in the urban center area should be transported by pipelines and disposed of in a centralized man- ner. There are obvious economic and technical advantages within a certain scale and scope.
