%X A test was conducted to examine the effect of several electron donors such as glucose, sodium acetate, Fe0, Fe0+glucose and Fe0+sodium acetate on reductive dechlorination of 2,4-dichlorophenol (2,4-DCP) through inoculating the unacclimated anaerobic mixed bacteria. The optimum condition and sustainability of Fe0 as electron donor was also been discussed. The results showed that, Fe0+glucose enhanced the dechlorination of contaminant effectively compared to glucose. Sodium acetate, Fe0 and Fe0+sodium acetate were all effective electron donors and Fe0 was the optimum, the optimum initial pH was 8.0 and quantity of added Fe0 was 2.0 g/L. 4-CP was the mainly intermediate product for 2,4-DCP dechlorination. Fe0 could support the electron for reductive dechlorination of 2,4-DCP continuously. In contrast, when sodium acetate as electron donor, the effect of dechlorination was inferior to Fe0 with the consumption of sodium acetate.
