摘　　要：高压脉冲灭菌是一项新型的非热处理灭菌技术,其实质是利用高强度脉冲电场瞬时破坏细菌的细胞膜从而导致细菌死亡。针对细菌在其生命周期内的排泄物吸附水中杂质而产生的生物粘泥对循环冷却水系统造成的危害,设计了一套基于Marx电路的高压脉冲灭菌装置,并构建了微型的模拟循环水系统。通过电磁场仿真软件对处理腔内部电场分布进行了仿真和分析,最后利用该高压脉冲处理系统进行灭菌实验。实验结果表明:该系统的灭菌效果很好,且该高压脉冲灭菌技术有望通过进一步的研究推广应用于发电厂循环冷却水系统的灭菌阻垢中。High-voltage pulse sterilization is a new type of non-thermal sterilization technology whose mechanism is that high-intensity pulsed electric field can destroy the cell membrane of bacteria instantaneously,so as to induce bacterial death. In accordance with the harm to the circulating cooling water system which is caused by the biological slime produced by combination between excreta in bacterial life cycle and impurities in water,we designed a high-voltage pulse device for sterilization based on the Marx circuit,and built a micro-simulation circulating water system. Moreover,we simulated and analyzed the internal electric field distribution of cavity by electromagnetic field simulation software,and carried out the sterilization experiment by high-voltage pulse treatment system. The results suggest that this system has a commendable sterilizing effect. Moreover,the high-voltage pulse sterilization technology is expected to spread and use in sterilization and descaling for circulating cooling water system of power plant through further research.
