| 摘 要： | 为提高电镀废水生物处理系统的稳定性,采用磁粉-弱磁场强化污泥系统。结果表明,实验系统COD_(Cr)、NH_3-N、Cu~(2+)和Ni~(2+)去除率分别比对照系统高12.55%、23.32%、21.13%和26.39%,污泥MLSS、FA(絮凝能力)和PN/PS(蛋白质/多糖)值也分别高出对照系统65.08%、68.48%和23.66%,强化后出水指标均达到电镀污染物排放新标准要求。

| Abstract: | In order to improve the stability of biological treatment process for electroplating wastewater treatment,magnetic powder-weak magnetic field was added to strengthen the activated sludge treatment process.The results showed that the removal efficiencies of CODCr,NH3-N,Cu2+ and Ni2+ in the magnetic powder-weak magnetic field strengthen system were higher than those of the contrasted system by 12.55％,23.32％,21.13％ and 26.39％,respectively.Moreover,the MLSS mass concentration FA as well as the PN/PS ratio were also higher than those of the contrasted system by 65.08％,68.48％ and 23.66％,respectively.The effluent quality of the test system met the new emission standard of electroplating wastewater after strengthening. |
