摘要
本文从理论和试验结果阐述了废水电凝聚处理的效能和作用机制。测试了铁电极的极化曲线,提出了电流效率和阳极溶铁量的关系,研究了亚铁离子在处理水和泥渣中的分配比例以及pH对电凝聚效果的影响,最后对电凝聚和化学凝聚的效果进行了对比.
Based on theory and experimental results,this paper discusses theefficiency and mechanism of electrocoagulation in wastewater treatment.It determines the polarized curve of the ferro-electrode,and proposesthe relationship between the efficiency of electric current and the contentof dissolved fero on positive electrode.It also studies the distributionproportion of ferrousion in water and sludge,and the effect of pH onelectrocoagulation.At last the effect of electrocoagulation and chemi-coagulation are compared.
