摘　　要：采用六水合氯化铁溶液对含磷水溶液进行除磷实验,研究了铁添加量、初始pH、温度对除磷的影响,同时考察了氯化铁对同一pH不同浓度含磷水溶液处理效率的问题。结果表明:(1)在溶液pH为弱酸性条件,添加适量铁溶液,反应pH为3.0~6.0,能够使水中残余磷达到污水排放标准0.5 mg/L;(2)含磷浓度越高,同等倍数添加量下,处理效率略呈降低趋势。Using six hydrated ferric chloride solution on phosphorus wastewater phosphorus removal experiment. Study the influence of dephosphorization of the iron content, initial pH and temperature. Investigates the processing efficiency of six hydrated ferric chloride solution with the same pH. The results showed that： （ 1 ） the pH of wastewater was weakly acidic, an iron solution was added, the reaction pH was 3.0-45.0, which could reach the sewage discharge standard of 0.5 mg/L （2） the higher the concentration of phosphorus, the treatment efficiency is slightly reduced with the equal multiple is added.
