铁碳微电解预处理灭多威废水研究

Research on Iron-carbon Micro-electrolysis for Methomyl Wastewater Pretreatment

采用铁碳微电解方法进行灭多威废水的预处理,考察了铁碳质量比、反应初始pH值、曝气量和反应时间等对废水处理效果的影响。结果表明,最佳铁碳比为1∶1、pH=4.0、曝气量6 L/min、电解时间100 min时,B/C由原水的不足0.1提高到出水的0.38,废水的可生化性显著提高。

The methomyl wastewater was pretreated by iron-carbon micro-electrolysis method.The initial ratio of iron-carbon,pH value,aeration rate and reaction time were studied.The results showed that the optimal ratio of iron-carbon,pH value,aeration rate and reaction time was 1∶1,4.0,6 L/min and 100 min,respectively.The ratio of B/C raised from less than 0.1 to 0.38,resulting in significant increase of the methomyl wastewater biodegradation.
