[Objective] The pollutants distribution during grassland digestion and utilization of rural domestic sewage was explored in order to provide a scientific reference for risk prevention and control in the resource utilization of rural domestic sewage. [Methods] This study investigated the effects of hydraulic load on soil solution and soil pollutant distribution during the grassland digestion and utilization of rural domestic sewage. It also analyzed the variations in soil solution and soil pollutants at different depths and explored the correlation among hydraulic load, soil solution, adn soil pollutants using the Pearson correlation coefficient. [Results] ① As the hydraulic load increased gradually from 0.005 m³/(m²·d) to 0.05 m³/(m²·d), an accumulation of NH⁺₄-N and NO^-₃-N was observed in the grassland. The poor denitrification performance of NO^-₃-N was identified as the limiting step restricting the denitrification rate of the grassland. ② The hydraulic load showed a strong positive correlation with the NH⁺₄-N content in the soil, with a correlation coefficient of 0.94. [Conclusion] During the grassland digestion and utilization of rural domestic sewage, it is necessary to distribute the hydraulic load rationally and control the environmental risks.
