Experimental results showed that under the conditions of pH 7.0,Fe0 5 g ·L-1 and 2,4,6-TCP 30mg ·L-1,the growth and interface enrichment of enriched-bacteria could be promoted by Fe0,the cell mass (expressed by D600) of Fe0/enriched-bacteria was about 1.7 times as high as that of the individual predominant groups of dechlorinating bacteria. After 96 h reaction, large amount of bacteria attached to the iron surface, with short rod or coccus-like morphology. The pH value of the system was maintained at 7.8, which could be beneficial to the reductive dechlorination reaction and the growth of the enriched-bacteria. The major pathway of 2,4,6-TCP degradation in the Fe0/enriched-bacteria system was 2,4,6-TCP to 2,4-DCP and then to 4-CP. %K Fe0/enriched-bacteria %K 2 %K 4 %K 6-trichlorophenol %K reductive dechlorination %K interface enrichment %K degradation pathway
