摘要
研究了共存离子对电絮凝去除含镉废水的影响,主要考察了硫酸根、碳酸根、碳酸氢根、硅酸根和铵根五种离子的影响,通过影响系数来表征影响的大小。实验结果表明,硫酸根、碳酸根的存在有利,碳酸氢根、铵根和硅酸根的存在不利,并且硅酸根的影响复杂。
A study was made on the influences of coexisting ions on the removal of waste water containing cadmium by electroflocculation with focus on the influences of five kinds of ions such as ionic sulfate, carbonate, bicarbonate, silicate and ammonium. The degree of the influence was characterized by the influence coefficient. The experimental results showed that the ionic sulfate and carbonate were favorable while the ionic bicarbonate, ammonium and silicate were unfavorable, moreover, the effect of the ionic silicate is complex.
