水体溶解性磷去除与回收技术进展探讨

Discussion on Progress in Removal and Recovery Technologies of Dissolved Phosphorus in Water Bodies

摘要:

相比于氮,控磷对防止水体富营养化具有更为直接的作用,同时考虑到自然界中磷循环的超长周期及人工开采磷矿的环境效应,有效回收溶解性磷具有重要的现实意义。文章从固相析出、生物生态、吸附交换等角度综述了当前水中溶解性磷去除与回收的技术进展,并对比分析了不同技术的适用条件和优缺点,指出了未来发展方向。

Abstract:

Compared with nitrogen, phosphorus control plays a more direct role in preventing water eutrophication. Considering the extremely long cycle of natural phosphorus circulation and the environmental impacts of artificial phosphate rock mining, efficient recovery of dissolved phosphorus is of great practical significance. This paper reviews the latest progress of technologies for removing and recovering dissolved phosphorus from water, in terms of solid-phase precipitation, biological and ecological methods, as well as adsorption and exchange. The applicable conditions, advantages and disadvantages of different technologies are compared and analyzed, and the future development directions are proposed.
