摘　　要：利用凹凸棒复合滤料良好的吸附性和生物挂膜性能对普通滤池进行生物强化,研究生物过滤对原水中苯酚的去除效果及影响因素。实验结果表明,原水浓度在0.25mg/L时,苯酚的去除率达到93.75%;温度在23℃时,苯酚的去除率达到95.97%;原水溶解氧浓度在7.4mg/L时,苯酚的去除率达到96.46%;反冲洗对生物过滤去除苯酚的影响较小,去除率在冲洗2h后能够恢复到冲洗前的水平。Attapulgite composite filter with its good absorption and biofilm performance on enhanced biological filter,the removal effect and factors of biofiltration to phenol in raw water were studied.The results showed that phenol elimination rate achieved 93.75% when raw water concentration was 0.25mg/L.Phenol elimination rate achieved 95.97% when solution temperature was 23℃.Phenol elimination rate achieved 96.46% when raw water dissolved oxygen concentration was 7.4mg/L.Backwashing had little effect on removal of phenol with biofiltration and the elimination rate resumed the level of preceding backwashing after 2h.
