摘要: 通过摇床间歇实验，研究了厌氧微生物与零价铁（Fe0）联合体系降解2,4,6-三氯酚（TCP）的特性，结果表明，在pH 7.5，35℃，150 r/min，Fe0 10 g/L条件下，TCP初始浓度为30 mg/L时，TCP降解的拟一级反应速率常数为0.0207 h-1，添加少量碳源可达到0.0390 h-1，其降解速率是前者的1.88倍；添加碳源的体系在220 h内连续多次投加TCP降解率都达到80%以上，而不加碳源的体系在第2次投加TCP后降解率就只有30%左右；添加不同碳源，降解速率不同；添加2-溴乙烷磺酸钠（BESA）以及SO2-4、NO-3和S2-对TCP降解有不同的抑制作用。

Abstract: The degradation of aqueous 2,4,6-trichlorophenol ( TCP ) by anaerobic microbe combined with element iron (microbe/ Fe0) was investigated. Under the conditions of pH 7.5, 35℃,150 r/min， Fe0 10 g/L, the pseudo-first-order rate constant of the degradation of TCP was 0.0207 h-1when medium contained 30 mg/L TCP. Moreover, the degradation rate constant with some carbon source can reach 0.0390 h-1, approximately 1.88 times of the former. In the system with added carbon source, the degradation rate of TCP could reach more than 80% for three times adding during 220 h. In the system which had no carbon source, the degradation rate was about 30% at the second time. Different carbon sources have different effects on the degradation velocity of TCP by microbe/Fe0. BESA, S2-, SO2-4 and NO-3 have different inhibition on the degradation of TCP by microbe/ Fe0.
