Experimental research on resource utilization of rural domestic sewage using an improved infiltration system to address the environmental pollution caused by rural domestic sewage.The results show that the improved infiltration system using 2 mm quartz sand as filler and supplemented with aeration facilities can withstand greater hydraulic loads.Under the condition of hydraulic load of 0.4 m/d,the average removal rates of COD and SS by the infiltration system are 95.7%and 90.3%,and the average retention rates of TP and TN are 73.2%and 83.4%.The effluent water quality meets the standards for raw vegetables in the GB 5084-2021"Irrigation water quality standards for farmland",while effectively retaining the nitrogen and phosphorus elements,and has a good effect on the resource utilization and treatment of rural domestic sewage.
