摘要：以硅藻土和纤维素为原料，通过溶胶一凝胶法制备出了新型硅藻土/纤维素复合助滤剂，探究了各种制备条件对助滤剂的影响，并在高岭土悬浊液中对硅藻土、纤维素和硅藻土/纤维素的助滤性能进行了比较，同时研究了硅藻土/纤维素助滤剂对实际微污染水过滤的影响。研究结果表明：复合助滤剂的最佳制备条件为纤硅比0.67，氨水浓度5.0X10-*mol/L，蒸馅水/纤维素 40mL/gEtOH/硅藻土20mL/g+60℃恒温水浴；硅藻土/纤维素复合助滤剂的助滤性能要明显优于硅藻土和纤维素助滤剂；在微污染原水直接过滤过程中，投加硅藻土/纤维素助滤剂可提高各微污染物的去除率，结合微滤膜深度处理工艺，最终出水水质满足《生活饮用水卫生标准》(GB5749-2006）的要求。

Abstract: The diatomite/cellulose filter aids were prepared using raw diatomite and cellulose via sol-gel technique.The effect of cellulose/diatomite distilled water/cellulose+ EtOH/diatomite, ammonia concentration and temperature on the properties of diatomite/cellulose filter aids were investigated. The filtration efficiency of diatomite, cellulose and diatomite/cellulose filter aids was compared. The influence of diatomite/cellulose filter aids on slightly polluted water filtration was studied. Results indicated that when 40 mL distilled water dissolved 1. 0 g cellulose, 20 mLEtOH carried 1. 5 g diatomite, the ratio of diatomite to cellulose was O.67, the concentration of ammonia was 5 X1o*mol/L, the temperature was 60
