摘　　要：地下土壤渗滤技术(SSIT)是一种分散式污水处理装置,由于其建造费用低、运行维护简单及污水无害化程度高等优点被广泛应用于分散污水治理。系统总结了SSIT研究发展现状和存在的主要问题,梳理了近20年内国内外在SSIT的研究进展、取得的主要成果。重点综述了影响SSIT脱氮效率低的主要因素(进水碳氮比、间歇运行、分流进水及曝气强度)及强化脱氮技术(基质填料添加、纯化菌种或活性污泥接种及耦合工艺研发)。最后总结了SSIT面临的挑战及研究潜力,为我国SSIT在分散污水处理领域的发展提供科学和实践依据。Subsurface soil infiltration technology(SSIT) is a decentralized sewage treatment device, which is widely used in decentralized sewage treatment because of its low construction cost, simple operation and maintenance, and high degree of harmless sewage. This paper systematically summarizes the development status and main problems of SSIT research, and combs the research progress and main achievements of SSIT at home and abroad in the past 20 years. This paper attaches advances on the affecting factors of dentitrification, for example, influent carbon nitrogen ratio, intermittent operation, diversion influent and aeration intensity. In addition, this article also discusses strengthening measures of dentitrification, such as, matrix filler addition, purified bacteria or activated sludge inoculation and coupling process research. Finally, the challenges and research potential of SSIT are presented, which provides a scientific and practical basis for the development of SSIT in the field of decentralized sewage treatment in China.
