对合成氨工业废水监测项目的建议

目前合成氨工业废水中氨氮浓度较高，并间接造成ｐＨ较高，构成合成氨企业的主要废水污染物．而国家级环境监测规范，即《环境监测技术规范》（地表水和废水部分）（国家环境保护局，１９８６）却没有规定要开展氮肥工业废水中氨氮等指标的监测和控制。鉴此，有必要根据优先监测原则，增加合成氨工业废水中氨氮、ｐＨ等项目的监测和控制．

PROPOSAL ON MONITORING ITEMS OF WASTE WATER FROM SYNTHETIC AMMONIA INDUSTRY

t prarent,the coarentration of ammonia and nitrogen in waste water from synthetic ammonia industry is high.which leads to higher pH value indirectly and plays a leading position among pollutants in waste waer.But,the monitoring and control of ammonia and mirroger in waste weter from Synthetic ammonia industries has not been stipulated in present national standard concerned.Therefore,tbe monitoring and control of ammonia and nitrogen and pH value of waste weter from synthetic ammonia industry are added according to prior monitoring principle
