摘要
研究了沙子、砾石、珍珠岩三种填料对生活污水中氨氮(NH_3-N)的去除效果。结果表明：,沙子对污水中NH_3-N的去除效果最好,珍珠岩次之,砾石的去除效果最差。三种填料对生活污水中NH_3-N的平均去除率分别为59.6%、20.4%和13.3%。
The removal efficiency of NH3-N with three kinds of fillers （sand, gravel, perlite） for domestic wastewater was studied. The results showed that the sand had the best effect on removing the NH3 - N in the domestic wastewater, which was followed by the perlite, while the effect of gravel was the poorest. The average removal rates of the NH3- N in the domestic wastewater were 57%, 20.8%and12.3%, respectively.
