The factors of effluent NH3-N removal rate of wastewater land treatment was analyzed as an example of artificial rapid infiltration system.
以人工快速渗滤系统处理污水为例，分析了污水土地处理中nh3 - N去除率的影响因素。
The reduction speed is increasing along with the concentration of N and P in water, whereas the removal rate of N and P is descending.
氮磷浓度的降低 速率随水体中氮磷浓度的升高而升高，而对氮磷的去除率随水体中氮磷浓度的升高而降低。
The removal rate of COD, NH3-N, HCHO were high, and the average removal rate of them were over 93%, especially, the HCHO's removal rate reached over 99%.
对于COD、氨氮（NH3-N）、甲醛（HCHO）的去除率高，各项指标的平均去除率为93%以上，尤其是HCHO的去除率高达99%以上。
