Low-energy-consumption sectional type artificial rapid infiltration system capable of strengthening sewage treatment efficiency of villages and towns

The invention discloses a low-energy-consumption sectional type artificial rapid infiltration system for enhancing the village and town sewage treatment efficiency, which is characterized in that the structure of a traditional artificial rapid infiltration system is improved, a two-stage artificial rapid infiltration system is constructed, the two-stage artificial rapid infiltration system comprises a water inlet tank, an artificial rapid infiltration tank I and an artificial rapid infiltration tank II, and the quality and efficiency of the village and town sewage are improved. Agricultural waste is used as a denitrification external carbon source to be added into a slow-release carbon source layer of the second artificial rapid infiltration tank, a commercial-grade liquid carbon source does not need to be added, the treatment cost is saved, resource utilization of the agricultural waste is achieved, and regular replacement of the agricultural waste is facilitated through the design of a partition plate in th
