摘要： 对比考察了厌氧生物处理（AD）、ZVI处理和ZVI-AD协同处理对喹啉的处理效果。结果表明，ZVI能够明显促进厌氧微生物降解喹啉的能力。通过考察协同体系中pH和ZVI投加量对降解喹啉的影响，得出体系的最佳pH=7.5，ZVI投加质量浓度3 g/L。在最佳试验条件下，处理96 h时，喹啉降解率可提高到80.5%，而甲烷产量比单独AD处理提升2.4倍。

Abstract: The effects of anaerobic biological treatment(AD),ZVI treatment and ZVI-AD synergetic treatment on the treatment of quinoline in wastewater have been compared and investigated. Experimental results show that ZVI could significantly facilitate the anaerobic biological degradation capability for quinoline. Through investigating the influences of pH and ZVI dosage in the synergetic system(ZVI-AD system) on the degradation of quinoline,it is found that the optimal pH is 7.5 and ZVI dosage 3 g/L. Under the optimum conditions,the degradation rate of quinoline could be increased to 80.5% in 96 h,while methane yield is 2.4 times higher than that of single AD treatment.
