摘　　要：恶臭废气破坏环境的同时对周边居民生活造成很大困扰,而且还比较难以完全消除。本文提出了利用双介质阻挡放电(DBD)等离子体协同催化系统去除恶臭废气。系统采用排管式DBD模块,结合分段式催化模块。对垃圾处置中心外排臭气进行中试研究,并给出了将垃圾恶臭废气的综合治理方案。结果显示:单一双DBD等离子体输入功率在0.5~2 kW区间内,输入功率与臭气中各污染物的降解率呈现正相关,其中臭味浓度的降解率最高约为75%。采用双DBD等离子体协同催化恶臭废气的方式对O 3的平均催化分解率可达94%,臭味浓度的降解率由75%提高到95%。这对恶臭废气处理技术在电力工业等许多行业中应用具有重要的意义和价值。In order to verify the odor removal ability of the dual-dielectric barrier discharge(DBD)plasma co-catalytic system,a pilot test study was carried out with the exhaust of odor from garbage disposal center combined with the stepwise catalytic module,and a comprehensive treatment scheme of odor from garbage was presented.The results show that when the input power of a single double DBD plasma is in the range of 0.5~2 kW,the degradation rate of each pollutant in odor increases with the increase of input power,and the degradation rate of odor concentration is up to 75%.When double DBD plasma is used to catalyze odor waste gas,the average catalytic decomposition rate of O_(3) can reach 94%,and the degradation rate of odor concentration increases from 75%to 95%.It is of great significance and value to the application of odor waste gas treatment technology in many industries such as electric power industry.
