湿法磷酸生产污水循环利用研究与应用

Study and Application of Wastewater Cycle Utilization in Wet-scale Phosphoric Acid Plant

介绍湿法磷酸生产中污水回收再利用技术。污水封闭循环利用不外排放 ,彻底根除污水排放造成的污染 ,同时回收了污水中的有效成分 ,又节约大量工业用水。

This article describles the wastewater recovery and cycle utilization technique for wet-scale phosphoric acid plant. Wastewater is cycled in a closed loop. Pollution due to wastewater discharge is eliminated thoroughly. Valuable components are recovered form the wastewater, besides, a large amount of water is saved.
