Urea is the most widely used nitrogen fertilizer in the world, and it is also an important raw material for plastics, medicine, food and other industries. Every year, the world's urea production has exceeded 140 million tons, and such a large amount of urea production is bound to produce a large amount of industrial wastewater. Urea wastewater has a large discharge and is harmful to ecological environment and human beings. Urea contains a large amount of nitrogen required for microbial growth, which easily leads to eutrophication of water body. As circulating water, it will also corrode equipment, which will not only increase the cost, but also cause production accidents if the maintenance is not timely.

项目简介：
尿素是全世界使用量最大的氮肥品种，同时也是塑料、医药、食品等工业的重要原料。每年全世界的尿素产量已超过1.4亿吨，如此大的尿素产量必定会产生大量的工业废水。尿素废水排放量很大，并且对生态环境和人类具有较大危害。尿素中含有大量微生物生长所需的氮元素，极易导致水体富营养化。作为循环水也会腐蚀设备，不仅提高成本，若检修不及时还可能造成生产事故。
项目创新点：
对ANAMMOX菌降解尿素的可行性进行分析，确定其代谢途径及反应的化学反应计量方程，为ANAMMOX菌降解尿素的规律提供可靠的机理支撑；在工程应用上，对尿素废水的处理提出新思路和新技术，探讨ANAMMOX工艺处理尿素废水的最佳工艺条件。
项目成果： 发表研究论文
