| 摘 要： | 为使酸性矿井水总铁浓度达到《地表水环境质量标准》(GB3838-2002)Ⅲ类要求,将中和沉淀与絮凝工艺相结合,分析了CaO、NaOH、PAC等药剂投加量对处理效果的影响。结果表明:在原水总铁浓度为466mg/L、Fe^2+浓度为15.6mg/L、pH=3.04的条件下达到同等除铁效果,采用CaO作为中和剂的投加量少于NaOH;在单独投加1200mg/LCaO的情况下,pH达到7.43,总铁及Fe^2+浓度分别降至5.7mg/L和0.06mg/L,总铁去除率达到98.8%;选用CaO投加量为1000mg/L情况下的中和沉淀上清液(pH=6.26)进行絮凝强化处理,当PAC和PAM投加量分别为30mg/L和0.2mg/L时,总铁浓度由11.8mg/L降至0.28mg/L。
