In this research, the authors used an improved multilayer infiltration system to treat the slightly polluted reservoir water of the Shangzhuang Reservoir in the Haidian District of Beijing. Multi-transitional layers were adopted to increase the interface contact between the suspended organic matter and oxygen. Biological nitrogen removal through nitrification and denitrification was the main removal mechanism of nitrogen. Phosphorus in waste water was mainly removed by fixation processed in the soil, such as adsorption and chemical precipitation.
