摘要
文章采用石墨为电极,研究了电化学法对沼液预处理效果,考察了极电压、反应时间、极板间距、初始pH值及不同电化学反应条件对沼液中COD和TP的去除率影响,确定了电化学法处理沼液的最佳试验条件,结果表明,极电压15 V,反应时间3.0 h,极板间距20 mm,初始pH值为5.0,在改变电化学反应条件的情况下都可以提高出水COD和TP的去除率。
Electrochemical process was applied in the pretreatment of biogas slurry by using graphite electrode. The effects of voltage, reaction time, electrode distance, initial pH and different electrochemical reaction conditions on the removal rate of COD and TP were investigated to optimize the pretreatment conditions. The results showed the optimum process condition of voltage 15 V, reaction time 3.0 h, initial pH 5.0, and electrode distance 20 mm. The removal rate of COD and TP could be improved evidently through the changing of electrode conditions.
