Degradation of Black Water Caused by Phytoplankton Using Electrochemical Oxidation Technique

  • 摘要: 为探索电化学氧化技术降解藻源性湖泛的可行性和实施效果,选取太湖藻华发生水域的浓缩藻类在室内稀释后,于高温黑暗条件下腐烂形成湖泛水样. 用钛基阴阳极板于24 V额定电压、100 W额定功率的变压器下在室内进行降解,并分别设置3个试验组和1个对照组. 结果表明:反应51 h后ρ(Chla)从初始的2 909.87 μg/L降至72.02 μg/L,降解率达97.6%;悬浮物〔OSM(有机悬浮物)、ISM(无机悬浮物)、TSM(总悬浮物)〕、含氮污染物〔TN、TDN(溶解性总氮)〕、CODMn、DOC(溶解性有机碳)的降解率分别为40.8~94.7%、37.4~58.9%、78.8%、40.1%;电化学氧化法对水体有机物的降解效果好,而短期内水体藻类污染物的自降解能力较为微弱. 电化学氧化法能有效去除湖泊水体中的藻类污染物,并且极板功率较小、反应时间短.
