摘　　要：针对高盐、高浓度有机污染物(COD)焦化浓盐水COD去除率低、难以达标问题,首次采用了低温湿式催化氧化技术(LDO),开展了该技术处理3种不同浓度焦化浓盐水的效果实验。结果表明:针对不同浓度有机污染物和含盐量的焦化浓盐水,LDO均可通过调节氧化剂的加入量提升去除效果,去除率超过90%,效果优于常规处理工艺。Aiming at the low COD removal rate of high salt and high concentration organic pollutants(COD)in coking brine,which is hard to reach the standard,low temperature wet catalytic oxidation(LDO)was initially used.Experiments were conducted on this technology in treatment of three different concentrations of coking concentrated brines.The results show that LDO can improve the removal effect by adjusting the amount of oxidant added according to different concentrations of organic pollutants and salt content of coking concentrated brines,with removal rate up to 90%,superior to conventional treatment technologies.
