采用凹凸棒复合滤料部分替代再英砂滤料，利用凹凸棒复合滤料良好的吸附和生物挂膜性能对普通滤池进行生物强化。探讨了温度，水力负荷，初始浓度对生物过滤去除水中Ni^2＋的吸附效果的影响。实验结果表明，温度在17．5～20℃时，吸附率可达87．14％数上，最高可达到93．17％；降低滤速可提高滤料对Ni^2＋去除率，最佳水力负荷为4m／h；Ni^2＋初始浓度在2-4mgm时滤料的吸附效果显著。

The study used attapulgite composite filter with its good absorption and biofilm performance on enhanced biological ftter instead of normal filter partial substitution of quartz sand with attapulgite composite filter. The test discussed temperature, hydraulic loading and initial concentration on Ni2＋ biofiltration removal from raw water. Experimental results showed that when the reaction temperature was from 17.5 ℃ to 20℃, the adsorption rate being over 87.14 % and the highest removal rate being 93.17 %; Reduction of the filtration rate can increase the removal rate of the Ni^2＋ and the best hydraulic loading condition was 4m/h; The adsorption effect was significantly when initial concentration of Ni^2＋ being from 2 mg/L to 4 mg/L.
