摘要
印制电路板废水种类较多,水质复杂,主要有高浓度的有机废水、高重金属含量的电镀废水。本试验根据不同水质采取不同的酸化-气浮、化学沉淀、接触氧化等工艺可使废水达到排放标准,其中沉淀产生的沉淀渣中含镍35%,具有较高的回收利用价值。
Printed circuit board wastewater sort is more complex,water complex,basically,there are high concentrations of organic wastewater,high heavy metal content of electroplating wastewater.The study according to different water quality take different methods to make the wastewater discharge standard,such as acidification-floating,chemical precipitation,contact oxidation process and so on,including precipitation to produce precipitation slag containing nickel 35 %,has high recycling value.
