小型地下污水处理厂设计概要

Summarization on Design of Small-sized Underground Wastewater Treatment Plant

依托国内多个地下污水处理厂建设经验,对小型地下污水处理厂的特点和设计要点进行探讨。小型地下污水厂地面层面积小,地面设施和建筑占用率高,难以作为公共绿地使用,在设计中应摆脱大型地下污水厂将地面层整体利用为绿化公园的思路,发挥其规模小、灵活性高的优势,采用合理加盖形式降低地下结构埋深,提高集约化程度,统筹考虑地面建筑与景观的关系,节约用地,减少造价,提高环境效益。

Based on the construction experience of several underground wastewater treatment plants(WWTP)in China, this paper discusses the characteristics and design gist of small-sized underground WWTP. Due to the fact that small-sized underground WWTP has the small ground area and high ground building density, its ground level can hardly be used as the public green area. Therefore, the design of such plants shall focus on its advantage of small size and high flexibility without the idea of the overall utilization of the surface layer as the green park in large-sized WWTP. The reasonable covering method is used to reduce the embedment depth of underground structure, to improve the integration level, to comprehensively consider the relationship between the ground architecture and landscape, to save the land, to decrease the construction cost and to improve the environmental benefit.
