摘　　要：采用活化海泡石做为人工湿地系统的填料,考察该系统对生活污水中的氨氮和总磷去除效果。结果表明,海泡石人工湿地系统对氨氮和总磷均有较好的去除效果,进水为10 L的最佳进水量时,人工湿地对氨氮去除率较高,进水浓度在12 mg/L,pH在5.5时去除率可接近85%;总磷的去除在进水浓度为2 mg/L,pH值为6.5时去除率可达到91.1%。Using the activated sepiolite as constructed wetland fillers, the removal effect of ammonia nitrogen and total phosphorus with this system in domestic sewage were researched. The results showed that sepiolite constructed wetland system had better removal effect of ammonia nitrogen and total phosphorus. When the optimal water volume was 10 L, the removal rate of ammonia nitrogen was higher with constructed wetland. When the initial concentration was 12 mg/L and pH was 5.5, the removal rate of ammonia nitrogen can reach to 85%. When the initial concentration was 2 mg/L and pH was 6. 5, the removal rate of total phosphorus can reach to 91.1%.
