Fe^0/厌氧微生物联合体系处理2,4,6-三氯酚影响因素的研究

Degradation of 2,4,6-trichlorophenol by integrated microbial-Fe^0 treatment system and impact factors

利用Fe0/厌氧微生物联合体系对2,4,6-三氯酚(2,4,6-TCP)进行降解研究。结果表明,Fe0/厌氧微生物联合体系可以有效降解2,4,6-TCP,Fe0与厌氧微生物之间存在明显的协同效应。Fe0/厌氧微生物联合体系处理2,4,6-TCP的最优条件为:微生物接种量0.434 g VSS/L,Fe0投加量15 g/L,体系初始pH值7.0~8.0。

The degradation of 2,4,6-TCP using a combination of Fe^0 and anaerobic microorganism was studied. 2,4,6-TCP could be degraded effectively and the synergistic effect between Fe^0 and anaerobic microorganism was apparent. The influences of inoculation quantity of anaerobic sludge, Fe^0 dose, initial pH and initial concentration of 2,4,6-TCP were investigated by a series of batch experiments, and the optimum conditions for 2,4,6-TCP removal were as follows： inoculation 15 g/L, initial pH value, 7.0-8.0. quantity of anaerobic sludge, 0.434 g VSS/L, Fe^0 dose,
