摘　　要：氮肥生产是水资源污染重灾户,是重点治理行业。实现氮肥生产污水零排放,既要从生产工艺技术、设备、管理抓节水防污,尽量减少用水和污染水,又要采用三水闭路循环、生物法终端处理等多项防污先进工艺技术和管理进行治污减排。文章介绍了氮肥生产污水来源、治理技术、零排放技术在国内氮肥企业的实施和推广应用情况。The nitrogenous fertilizer production made water resources serious pollution, and was the key profession to governance. Realizing wastewater zero emissions in nitrogenous fertilizer production, the technique of production technology, the equipment, the management stress saving water antifouling, reduction the water use and the water pollution should be considered, and three water closed circuit, biological law terminal processing and other antifouling advanced processing technologies should be used and strengthen the management on the anti-pollution to reduce the emissions. The implementation and application of wastewater originatesl the government technology, zero emissions technology in the domestic nitrogenous fertilizer enterprises were introduced.
