摘要
对氨氮含量高的工业废水的水样，用国家标准法测定时需对水样进行预处理（絮凝沉淀法或蒸馏法）之后才能测定，用改进法测定时则不需要预处理，直接取水样显色后，用无氨水定量稀释，然后测定。试验证明，改进法省时省水省力，方法可行，结果令人满意。
For high ammonia-nitrogen waste water, it must be pretreatment by flocculation-precipitation or distillation method before determined according to the national standard. The improvement method that is no need to pretreatment is presented. The experiment results show that the improvement method is featured of cost saving, easy to operation with satisfactory results.
