为了更好地去除富营养化水体中的磷，本研究采用3种改性方法对凹凸棒土、黄黏土、沸石、高岭土和硅藻土进行改性，共改性出6种磷吸附剂。通过比较不同吸附剂处理的富营养化水中磷的浓度，去除率，氯、铝离子残留以及吸附磷的释放等，选出较佳的除磷吸附剂；并通过扫描电镜对除磷效果较好的吸附剂的表面进行分析。结果显示：改性吸附剂经改性后磷去除率均显著增加；不同改性吸附剂的磷去除率间差异显著，其中改性凹凸棒土的去除效果最佳。从吸附剂处理后磷的浓度和去除率等考虑，改性的凹凸棒土可用于富营养化河水磷的去除。

In order to remove phosphorus in heavily polluted river, six phosphorus adsorbents were made through the modification of attapulgite, yellow clay, zeolite, kaolinite and diatomite. The adsorbents showed improved effects on remo-ving phosphorus. By comparing the phosphorus concentration, removal rate and release, and chlorine and aluminum ion residues in heavily polluted water, it was found that the adsorbents, varied in phosphorus removal. The best phosphorus re-moving effect was achieved by using modified attapulgite. Scanning electron microscopy showed that the surface structure of modified attapulgite and its energy spectrum were changed. Modified attapulgite could be used for the phosphorus removal of eutrophic water.
