摘　　要：实验结果表明,以活性炭和甲壳素为悬浮载体的生物反应器,进水中NH3-N质量分数为50m g/L,水力停留时间为20h,投加量分别为8.93g/L、2.71g/L时,氨氮去除率接近于100%,为适宜的硝化细菌生长载体。Active carbon and chitin are better media for supporting nitrobacteria. The removing rate of ammonium at the two nitrified reactors using active carbon and chitin as nitrobacteria carriers can almost achieve 100%, while the influent ammonia concentration is 50mg/L, HRT is 20h, and the amount of active carbon and chitin are 8. 93 and 2. 71 mg/L.
