摘　　要：以COD去除率为指标,研究UV-Fenton氧化法对聚糖-木质素钻井液废液的降解处理效果并对处理条件进行优化。结果表明,影响UV-Fenton法聚糖-木质素钻井液废液COD去除的最主要因素为H_(2)O_(2)投加量;优化的UV-Fenton处理条件为双氧水(H_(2)O_(2))的投加体积比为1.20%,H_(2)O_(2)/Fe^(2+)的摩尔比为4.0和UV照射时间为20 min,在此条件下可使聚糖-木质素钻井液废液的COD去除率达75.6%。With COD removal rate as index,the UV-Fenton oxidation process of chitosan-the degradation of lignin waste drilling fluid treatment effect and optimize the processing condition.The results show that the main factor affecting COD removal of waste liquid of UV-Fenton farosan-lignin drilling fluid is the amount of H_(2)O_(2)added.Under the optimized UV-Fenton treatment conditions,the added volume ratio of H_(2)O_(2)was 1.20%,the molar ratio of H_(2)O_(2)/Fe^(2+)was 4.0 and the UV irradiation time was 20 min.Under these conditions,the COD removal rate of the waste fluid of glycan-lignin drilling fluid could reach 75.6%.
