GAC、UF、RO去除饮用水中氯仿、四氯化碳性能的试验研究

Experimental Studies on Removal of Chloroform and Tetrachloromen thane from Potable Water by GAC, UFand RO Process

研究了粒状活性炭（ＧＡＣ） 、超滤（ＵＦ） 和反渗透（ＲＯ） 对自来水中氯仿和四氯化碳的去除性能，探讨了ＧＡＣ对氯仿和四氯化碳去除的物理吸附和微生物降解机理。试验发现ＵＦ膜对氯仿和四氯化碳的快速吸附与脱附现象，并讨论了ＲＯ膜对不同浓度氯仿、四氯化碳的去除效果和作用机理。

This paper reports the results of applying granular activated carbon (GAC) ,ultrafiltration (UF) and reverse osmosis ( RO) to the treatment of potable water containing chloroform and tetra chloromethane.The physicaladsorption and biologicaldegradation mechanisms ofremoving chloroform andte trachloromethane by GACare discussed .Quick adsorption and desorption ofchloroform andtetrachloromethane by UFwere found in the study.In addition,the influence of the concentrations of chloroform and tetra chloromethanein raw water on theirremoval by ROprocess and its mechanism were studied .
