| 摘 要： | 对贵州大方的凹凸棒土进行热重分析,经过煅烧、碱、酸、盐改性,用改性凹凸棒土处理高浓度含磷废水,试验结果表明：经碱、盐改性凹凸棒土及煅烧凹凸棒土对磷酸根的去除率明显增加;而经酸改性凹凸棒土对磷酸根的去除率增加不明显。用经过500℃煅烧的凹凸棒土对洛阳市某企业排放水（含磷11.2mg/L）处理,去除率可达92.7%,符合国家二级排放标准。

| Abstract: | An analysis of attapulgite from Dafang by TGA.Using alter-attapulgite get by calcined、alkali、acid、salt modify treat high concentration of phosphorus waste water,laboratory results shows： there is a increase in the percentage of dephosphorization by alkali alter-attapulgite;however acidic alter-attapulgite has negligible effect on phosphate removal.The percentage of dephosphorization is increase by calcine attapulgite.The alter-attapulgite which calcined at 500℃ treat waste-water of an corporation in Luoyang city（phosphorus 11.2mg/L）,the removal rate reach 92.7%,conform national secondary emission standard. |
