介绍了我国目前随污水排放的磷引起水体富营养化的情况,叙述了化学和植物回收污水中磷的方法.利用磷富集植物回收水体中的磷,有利于磷资源的循环再利用,在缓解磷资源的危机的同时,可净化水质、保护环境,实现了双赢.指出应加强磷富集植物的筛选研究,为污染水体的修复和回收磷资源提供新的思路.

There are large quantities of phosphorus in wastewater, which corresponds to 1/3 of the yearly phosphorus output in China. This part of phosphorus can be transformed into resource by phosphorus-hyperaccumulator plants, with the simultaneous result of environment protection. At present, there are several phosphorus recovery techniques such as chemical precipitation, but it was high cost and low recovery rate. We discussed the feasibility of P removal and recovery from wastewater by p-hyperaccumulator plants uptake and harvest, and pointed out the further study should strengthen the screening of p-hvperaccumualtor plants.
