尿素废水处理及资源化技术研究进展

Recent Advances in Urea Wastewater Treatment and Resource Utilization Technology

随着人类社会的发展,工业生产、非科学施用氮肥和未妥善处置生活污水而产生的尿素废水大量进入环境,不仅对生态平衡和环境造成了破坏和污染,也对人类健康造成危害。同时,尿素作为能源载体,也已被广泛研究。因此,研究尿素废水的处理与资源化利用意义重大。根据国内、外现有研究资料,分别从物理法、化学法、生物法、和生物电化学法4个方面对近年来的尿素废水处理与资源化技术进行综述,以期为尿素废水高效处理与资源化利用提供参考和借鉴。

With the development of human society,a large number of urea wastewater produced by industrial production,unscientific application of nitxogen fertilizer,and improper disposal of domestic sewage enter the environment,not only cause damage and pollution to the ecological balance and environment,but also do harm to human health.Meanwhile,urea,as an energy carrier,has also been widely studied.Therefore,the study of the treatment and resource utilization technologies of urea wastewater is of great significance.According to the existing research at home and abroad,the treatment and resource utilization technologies of urea wastewater in recent years were carefully reviewed from the aspects of physical method,chemical method,biological method,and bio-electrochemical method.Hope this review will provide reference for the efficient urea wastewater treatment and resource utilization technologies.
