摘要 以铁矿浮选中含有的黄药为处理的目标物质,采用活性炭和紫外光与臭氧联用氧化雾化后的黄药。试验考察了pH值、臭氧通入量、活性炭、雾化、自由基捕获剂对黄药去除率的影响,并比较了曝气/O3/UV/GAC和雾化/O3/UV/GAC两种方法。结果表明,将废水雾化,不调节pH值,反应35 min,臭氧通入量为300 mg/L, 黄药的去除率达到96.3%,比曝气/O3/UV/GAC联用黄药的去除率提高了15%。该工艺可以作为含有黄药废水的深度处理手段。

Abstract: Xanthate in the process wastewater of iron ore flotation was selected as target substance.Study was made on treating the atomized Xanthate by a combination of activated carbon, ultraviolet light and ozone oxidation.The experiment investigated the influence of the pH value, ozone dosage, activated charcoal, atomization, free radical scavenger on the xanthate removal rate, and the two methods (atomization/O3/UV/GAC and aeration/O3/UV/GAC) were compared.The results show that, under the conditions of wastewater atomization, no pH adjustment, a reaction time of 35 minutes, and an ozone dosage of 300 mg/L, the xanthate removal rate was 96.3%, 15% higher than that by the process of aeration/O3/UV/GAC.This process can be used as a deep treatment means for xanthate-containing wastewater.
