Abstract

Soil infiltration system is a low-cost and high-efficiency decentralized wastewater treatment technology based on soil-microorganism-plant complex ecological effects. It can effectively remove pollutants such as organic matter (COD), suspended solids (SS), nitrogen, phosphorus and pathogenic microorganisms in wastewater mainly through synergistic mechanisms such as physical filtration, chemical adsorption and biodegradation. The system includes slow infiltration, rapid infiltration, surface overflow and underground infiltration. It can be flexibly applied to many fields such as rural domestic sewage, farmland irrigation and reuse, and some industrial wastewater treatment. Although there are still some limitations in nitrogen removal efficiency and soil clogging prevention and control, the soil infiltration system shows a good prospect of popularization and application through matrix improvement, process optimization and ecological coupling, especially in resource reuse and ecological management.

Keywords: Wastewater Treatment , Soil Infiltration Technology, Resource utilization.
