- 摘要:
- 含氮、磷的工业和养殖废水排放不当会引发水体富营养化，同时氮、磷也是人类和其他生物生命活动不可缺少的元素，尤其磷矿属于不可再生、不可替代的有限资源。基于可持续发展需要，从废水中同步回收氮和磷是解决氮磷污染和实现资源高效利用的重要途径，也是水处理和资源回收领域的研究热点。详细总结氮磷资源同步回收方法，并对电化学耦合回收技术以及膜分离耦合回收技术进行科学细致的分类，系统阐述各种回收方法的技术原理和优缺点，并指出目前氮磷资源同步回收研究中存在的问题和未来的发展方向。
- Abstract:
- The improper discharge of industrial and aquaculture wastewater containing nitrogen and phosphorus will lead to the eutrophication of water bodies. Nitrogen and phosphorus are indispensable elements for human and other biological life activities. Especially, phosphate ore is a non-renewable and irreplaceable limited resource. Based on the needs of sustainable development, the simultaneous recovery of nitrogen and phosphorus resources from wastewater is an important way to solve nitrogen and phosphorus pollution and to achieve efficient utilization of resources, which is also a research hotspot in the field of water treatment and resource recovery. In this work, the methods of simultaneous recovery of nitrogen and phosphorus resources are summarized in detail. The co?recovery technologies such as electrochemical coupling technology and MBR coupling technology, are scientifically and carefully classified, and the technical principles and advantages and disadvantages of various recycling methods are systematically expounded. The existing problems in the current synchronous recovery of nitrogen and phosphorus resources are pointed out, and future development directions are proposed.
