摘　　要：在新时代“两山”理论的指引下,市政设施在发挥功能同时,更加注重环境影响。近年来地下式污水厂作为一种节地、环境友好式建设形式被广泛应用。膜生物反应器(MBR)工艺作为创新膜技术,可取消传统工艺中二沉池和深度处理设施占地,在地下式污水厂中应用可大幅减少土建投资,并节约工程占地。文章以长沙市某座污水厂为例,介绍了AAOA+MBR工艺在地下式污水处理厂中的应用,总结地下式污水厂设计要点。该污水厂本次设计规模为25万m^(3)/d,其中土建一次完成,设备分两阶段安装,一阶段安装为12.5万m^(3)/d,采用AAOA+MBR+紫外消毒工艺,尾水排放标准优于湖南省地标一级标准。通过环境友好的建设模式,激活周边地块的开发价值,提升综合效益。本工程用地标准仅为0.3 m^(2)/(m^(3)·d^(-1)),远低于国家标准,为类似工程提供参考。Under the guidance of the"two mountains"theory in the new era,municipal facilities pay more attention to environmental impact while playing their functions.In recent years,underground wastewater treatment plants(WWTPs)have been widely used as a land saving and environment-friendly construction form.As an innovative membrane technology,membrane bio-reactor(MBR)process can eliminate traditional process such as secondary sedimentation tank and advanced treatment facilities.The application of MBR process in the WWTPs can greatly reduce the civil engineering investment and save the land occupation of the project.Taking a WWTP in Changsha as an example,this paper introduces the application of MBR process in underground WWTPs,and summarizes the design essentials of underground sewage plant.The design scale of the WWTP is 250000 m^(3)/d,and the main process is AAOA+MBR+UV.The effluent quality is superior to the first level standard of Hunan Province.Through the environment-friendly construction mode,the land value near the plant are activated.The land standard of this project is only 0.3 m2/(m^(3)·d-1)which is far lower than the national standard,this paper provides reference for similar projects.
