介绍了欧洲脉冲电晕 (PC) 处理污染流项目的技术概述。已经开发出多功能高功率系统，能够在电晕水反应器或气溶胶反应器中清洁异质介质中的水流和气态流。两个反应器都能够从水流中实现高苯酚去除率，并将几种不可生物降解废水的生化需氧量/化学需氧量比率提高到可以进一步生物降解的程度。 PC与催化剂相结合能够净化被甲苯、苯乙烯和恶臭成分污染的气流。甲苯的去除率已达到 99% 以上，并且具有非常高的除臭效率。高功率全固态紧凑型纳秒脉冲发生器的可靠运行也得到了证明。该项目的第二阶段设计了高功率脉冲发生器。一个压缩级足以在反应器上形成 60kV 3-J 脉冲，反应器的放电阻抗约为 100Ω，脉冲重复频率高达 500Hz；上升时间为 15 ns，持续时间为 100 ns。还分析了系统放大。规模达到 50 立方米/小时的系统的水处理费用估计为 2 欧元/立方米。含水有机废物流的焚烧成本可能高达 500 欧元/立方米或更高，具体取决于污染的性质，因此 PC 水处理技术可能会变得极具竞争力。未来计划在实验室条件和现场研究不同工业废物的已开发工艺的清洁效率
A technical overview of a European project on pulsed corona (PC) treatment of polluted streams is presented. Versatile high-power systems that are capable of cleaning both aqueous and gaseous streams in heterogeneous media, in either a corona above water reactor or an aerosol reactor, have been developed. Both reactors are capable of high-phenol removal yields from aqueous streams and increase the biochemical oxygen demand/chemical oxygen demand ratio for several nonbiodegradable wastewaters to such degree that further biodegradation becomes possible. The PC combined with a catalyst is capable of cleaning gaseous streams that are polluted by toluene, styrene, and malodorous constituents. Reduction rates of toluene that are higher than 99% have been achieved, and very high odor-removal efficiency has been demonstrated. The reliable operation of high-power all-solid-state compact nanosecond pulsers has also been demonstrated. For the second phase of the project, a high-power pulser was designed. One compression stage suffices for the formation of 60-kV 3-J pulses across a reactor that has a discharge impedance of approximately 100 Omega at a pulse repetition frequency of up to 500 Hz; the rise time is 15 ns, and the duration is 100 ns. The system scale-up is also analyzed. The estimated price of water treatment in systems that were scaled up to 50 m3 /h is 2 euro/m3. Incineration of aqueous organic waste streams can cost 500 euro/m3 or more, depending on the nature of the contamination, so the PC water-treatment technology may become highly competitive. It is planned in the future to investigate the cleaning efficiency of the developed processes with different industrial wastes, both at laboratory conditions and in the field
