氮肥生产是水资源污染重灾户,是重点治理行业。近年来氮肥行业为推进节能减排工作,在污染排放物处理领域全面推广了多项行之有效的先进工艺技术,正是这些先进节能减排技术的相互匹配和推广应用,使氮肥行业的能耗和环保水平有了明显提高。介绍了近期氮肥生产循环冷却水排污水双膜法处理、高浓度氨氮废水强化解络合-汽提精馏脱氨处理、离子液吸收弛放气中氨离子液吸收等新技术的开发与应用情况,这些新技术为氮肥行业实施节能减排提供了有力的技术支持,引起业界的极大关注。
Nitrogen production is a major source of water pollution, is a key management industry. In recent years, nitrogen fertilizer industry to promote energy-saving emission reduction work in the field of pollution emissions to promote a comprehensive range of effective advanced technology, it is these advanced energy-saving emission reduction technology to match and promote the use of each other so that the nitrogen fertilizer industry can Consumption and environmental protection has been significantly improved. This paper introduces the recent development of double membrane technology for the treatment of recirculation of cooling water in nitrogenous fertilizer production cycle, the enhanced deacidification of high concentration ammonia wastewater, the stripping rectification and de-ammonia treatment, the absorption of ammonia ion liquid in the absorption and desorption of ionic liquids The situation, these new technologies for the nitrogen fertilizer industry to implement energy-saving emission reduction provided a strong technical support, aroused great concern in the industry.
