【摘要】 考察了实际生产规模的臭氧粒状活性炭工艺以及小型超滤、纳滤、反渗透膜法两种典型饮用水深度净化工艺的处理效果。试验结果发现臭氧活性炭工艺具有优良、稳定的去除有机污染物功能,而孔径较小的活性炭纤维除污染效果并不好,臭氧氧化出水、超滤出水再用压缩活性炭进行吸附处理对有机物的去除效率要比直接处理原水高。超滤膜除有机物效率不高,而反渗透和纳滤膜在较好地去除水中有机物的同时,也去除了水中绝大部分无机物,出水有机物和无机物浓度都比较低。更多还原

【Abstract】 The operation experiment of pilot plant of ozonization activated carbon process and bench experiment of membrane process such as UF, NF, RO were carried out for comparison of the treatment effects of the two typical advanced water treatment processes. The results show that granular activated carbon and extruded carbon block are effective to remove organic substance in ozonization effluent. UF can not be considered as the main organic removing process, RO and NF are very efficient in the removal of pollutants and treated water contains little organic and inorganic substances.更多还原
