Electroporation has been evaluated as a potential backend wastewater treatment for deactivation of Ascaris suum eggs in buffer solution. Initial results indicate that eggshell permeability is affected by the pulse train electric field strength and duration. Coupling electroporation with chemical exposure, using low concentrations of commercially available disinfectants, allows oxidizing agents to pass through the complex strata of the A. suum eggshell, specifically reaching the innermost embryonic environment, which leads to successful deactivation compared to either method used separately. The aim of this work is to identify and develop an alternative technique that efficiently inactivates helminth eggs present in wastewater.

使用电穿孔灭活A虫卵,并通过化学消毒顺序灭活

电穿孔已经被评价为一种潜在的后端废水处理的失活猪蛔虫在缓冲溶液中的卵。初步结果表明,蛋壳的渗透性受脉冲序列电场强度和持续时间的影响。使用低浓度的市售消毒剂将电穿孔与化学暴露相结合,可使氧化剂穿过A. suum蛋壳的复杂层,特别是到达最内层的胚胎环境,与分别使用的两种方法相比,它都能成功失活。这项工作的目的是确定并开发出一种替代技术,该技术可以有效地灭活废水中的蠕虫卵。
