摘要
污水地下渗滤系统被广泛用于没有完善污水管网系统的农村地区分散式生活污水的处理,在评估其处理能力时,有限的脱氮能力仍然是制约传统污水地下渗滤系统的瓶颈。围绕污水地下渗滤系统的研究热点、存在问题及改进措施三方面进行综述,为污水地下渗滤系统在分散式生活污水处理中的应用提供借鉴。
Subsurface wastewater infiltration system(SWIS)was widely used to treat decentralized domestic sewage in rural areas without a complete sewage network system.The limited nitrogen removal efficiency was still the main problem of the traditional SWIS when assessing its treatment capacity.The research hotspots,existing problems and improvement measures of SWIS are reviewed,to provided a reference for the application of SWIS in distributed domestic sewage treatment.
