| 摘 要： | 为应对水体富营养化的日益严重,利用高压脉冲引发的气液两相放电产生的等离子体灭活铜绿微囊藻.研究了动态停留时间、分批次动态处理、不同稀释物以及处理方式对铜绿微囊藻叶绿素a去除效果的影响.研究结果表明:动态停留时间越长,处理当天藻液的叶绿素a去除率越高,而随着放置培养时间的增加,叶绿素a浓度下降的趋势也越明显;当动态停留时间相同时,一次处理比分批次处理的叶绿素a去除效果明显;用灭菌水稀释的藻液与用灭菌的NaCl溶液(质量分数为0.85%)稀释的藻液相比,前者叶绿素a的去除率远远高于后者;静态实验由于停留时间的相对增加,叶绿素a的去除率明显高于动态实验.本系统最佳的叶绿素a去除率高达97.13%,为灭活藻类提供了一种新方法.

| Abstract: | In order to solve the problem of the increasing labefaction of the eutrophic water,the inactivation of Microcystis aeruginosa(M.aeruginosa) with plasma generated by pulse discharge is proposed.Effects of various parameters such as dynamic treatment time,separated dynamic treatment,different diluted substance and treatment methods on the changes of the chlorophyll-a(Chl-a) of M.aeruginosa were investigated.Experimental results show that the removal efficiency of Chl-a increases after treatment and the Chl-a ... |
