摘要
电路板废水中的成分比较复杂,含有镍、铜等重金属离子、氰化物等,有机物含量较高,水质和水量不稳定,给废水处理领域造成较大的困难;处理的成本较大。本次废水处理实例中采用"二级物化处理+重金属过滤器+4S-MBR",工艺处理效果好,出水能够达到《电镀污染物排放标准》(GB21900-2008)表2标准要求,采用该方法去除污染物的效果最好。
PCB wastewater composition is more complex,containing nickel,copper and other heavy metals,cyanide and other,high organic content,unstable water quality and quantity,resulting in greater difficulties for wastewater treatment,It is large cost process. The examples used in wastewater treatment,"two physico- chemical treatment and heavy metal filter and4S- MBR",process effect is ok,Water can be achieved,"plating pollutant emission standards"( GB21900- 2008) Table 2standards,using this method for removing contaminants best.
