摘　　要：通过在含氨废水中投加脱氮菌,分别对某焦化厂和某氨基酸厂污水处理工艺中二沉池出水进行了小试验,研究了菌种投加后对于不同浓度含氨废水的去除情况。结果表明:未投加脱氮菌时,采用生物接触氧化法,废水氨氮去除率仅达到37%;投加脱氮菌后,较低和高浓度含氨废水的去除率均达到96%以上,氨氮去除效果显著提高。By adding denitrifying bacteria in the anamoniated wastewater, a small test was respectively made on the secondary sedimentation tank effluent in the wastewater treatment process of a coking plant and a amino acid factory. The removal cases for different concentrations of ammonia-containing wastewater after adding denitrifying bacteria were studied. The results show that before adding denitrifying bacteria, the ammonia removal rate of wastewater is only 37% by using biological contact oxidation; after adding denitrifying bacteria, the ammonia removal rates of low and high concentration of wastewater are more than 96%, ammonia removal efficiency is significantly improved.
