Soil column was equipped with the sediments and aquifer media collected from Weihe Riverbed and its bank, and was used to research the characteristics of aniline degradation in the riverbank filtration under sulfate-reducing conditions. The results show that most aniline could be degraded, even be mineralized by the indigenous microbes under sulfate-reducing conditions, but had a long lag period. The aniline degradation and sulfate reducing produce some intermediates, some of which are harmful

In the test process, aniline concentration in infiltrating water was about 33 mg/L, and in leacate increased from 0 to 22.7 mg/L, then dropped and kept at 2 mg/L or so. Aniline removal rate was 93.94% and total organic carbon removal rate was 62.13%. One of intermediates is H 2 S the most harmful to the microorganisms. The lag phase was about 14 days
