摘　　要：针对制革废水中氨氮超标问题进行试验研究,结果表明,冬季在皮革废水曝气池投加低温抗盐分硝化细菌菌种,增加活性污泥中的硝化菌数量,可提高氨氮去除率,在低温条件下使冬季皮革废水的出水氨氮达标排放。The experiment is conducted on exceeding standard problem of ammonia nitrogen in winter leather wastewater,the results show that adding low temperature and salt resistance nitrifying bacteria strains into the aeration tank of leather wastewater,increasing number of denitrifying bacteria in activated sludge,can improve the removal rate of ammonia nitrogen,and make the effluent of the winter leather wastewater meet with ammonia nitrogen emissions standards under the condition of low temperature.
