摘要
采用某卷烟厂污水处理系统产生的中水和自来水分别对烟草加工过程中产生的废气进行水洗,并分析了水洗前后废气、废水成分和处理效果.结果表明,废气中的污染物经中水水洗后转移至淋洗水中,中水水洗去除了废气中77.6％的乙醇及78.6％的非甲烷总烃,废气中的TVOCs经水洗后下降了 59.8％,总有机硫化物去除率高达94.6％,其中甲硫醇为有机硫化物主要成分,且经水洗后去除率高达96.4％.与自来水对比,采用中水能够有效去除废气中的污染物、节约水资源、降低运行成本.
Abstract
In this study,the reclaimed water generated from the sewage treatment plant is evaluated for replacing the tap water in an odorous gas water-washing process of a cigarette factory.The composition and treatment effect of waste gas and waste water before and after washing are analyzed.Results show that the pollutants in waste gas are transferred into the water after washing.The washing by reclaimed water removes 77.6％of ethanol and 78.6％of non-methane hydrocarbon in waste gas,and TVOCs in waste gas decreases by 59.8％after washing.The removal rate of total organic sulfide reaches 94.6％.The removal rate of methyl mercaptan,which is the main component of organic sulfide,is as high as 96.4％.Compared with tap water,the use of reclaimed water can effectively remove pollutants in waste gas,save water resources,and reduce operation cost.
