%X Artificial groundwater recharge is one of the efficient approaches in mitigating water shortage in China. With laboratory scale soil column system, this paper examined the migration and removal of organic matters in reclaimed wastewater during groundwater recharge. The results showed that after the secondary effluent pretreated by activated carbon was percolated through soil column system, the TOC, UV-254 and BOD5 in the effluent were removed by 44%, 34.36% and 95%, respectively, and the majority of the organic matters was removed in the first 0-0.5 m of soil column. When the TOC concentration of influent was 9-11 mg x L(-1), the variation of TOC concentration with soil depth during recharge followed exponential equation C = 10e (-0.6934h) (R2 = 0.8697). This equation could be used to well predict the TOC concentration of the effluent from soil column system.
