摘要
氮肥生产属重污染行业,生产过程中排出大量含有氨氮和其它污染因子的废水,对水体环境造成很大危害。COD和NH3-N是与污染有关的重要参数。为此,我们对洛阳地区3家氮肥生产企业污水排放情况进行了研究与分析,并提出了排放污水的标准和治理建议。
Nitrogenous Fertilizer Industry is heavily polluting industries, the production process from a large number containing ammonia and other waste water, which containing ammonia and other waste water pollution factor, may cause great harm on the water environment. For this reason, this composition is mainly about sewage emission of 3 Nitrogenous Fertilizer Industries and using the method to carry on systematic research of the production. The pollutants of concern in this region, which are eligible for trading, mainly include both chemical oxygen demand （COD） and ammonia - nitrogen （ NH3 - N）. Finally, the discussion and suggestion on emission standard of sewage was given.
