磷酸铵装置含氟污水收集处理的探析及建议

Analysis and Suggestions for Collection and Treatment of Fluorine-containing Waste Water from Ammonium Phosphate Plant

针对料浆法磷酸铵中氟含量较传统法高以及磷酸生产强调污水封闭循环利用,污水中的氟进入肥料中,对环境产生不利影响,建议加强磷酸铵生产污水集中收集,采用先进的污水处理技术,降低污水处理的成本,将污水处理后再循环利用,继而提高磷酸铵品质。

Given the higher fluorine content in the slurry-process ammonium phosphate than the traditional process,and the closed loop recycle of waste water during phosphoric acid production,the ingress of fluorine from the waste water into the fertilizer may pose adverse impact on the environment,it is suggested that waste water generated during ammonium phosphate production should be collected and treated using advanced waste water treatment technology,so as to reduce waste water treatment cost,recycle the treated waste water,and hence improve the ammonium phosphate quality.
