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p H和ZVI投加量对降解喹啉的影响,得出体系的最佳p H=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。The effects of anaerobic biological treatment（AD）,ZVI treatment and ZVI-AD synergetic treatment onthe treatment of quinoline in wastewater have been compared and investigated. Experimental results show that ZVIcould significantly facilitate the anaerobic biological degradation capability for quinoline. Through investigating theinfluences of p H and ZVI dosage in the synergetic system（ZVI-AD system）on the degradation of quinoline,it isfound that the optimal p H is 7.5 and ZVI dosage 3 g/L. Under the optimum conditions,the degradation rate of quino-line could be increased to 80.5% in 96 h,while methane yield is 2.4 times higher than that of single AD treatment.
