摘　　要：本文对以铁为电极进行电凝聚处理印染废水时pH值对铁电极行为的影响进行了研究。测出在恒电流条件下电解电压,阴极电位和阳极电位随PH值的变化曲线以及不同pH值条件下恒电位极化曲线。据此研究了电解时电极反应和应控制的pH条件。The effect of pH value on the behaviour of iron electrodes is studied in this paper, with printing and dyeing wastewater treated by electrolysis coagulation using soluble iron anodes. The curves for electrolysis volt, potentials of cathodes and anodes in relation to pH value of wastewater are measured, and the potentiostatic polarization curves under the conditions of variable pH value is also described. According to the results above, the electrode reactions and pH value required are presented as wastewater is electrolyzed.
