- 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.
