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CODCr、NH3-N、Cu2+和Ni2+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.
Study on Electroplating Wastewater Advanced Treatment by Activated Sludge System Coupled with Magnetic Powder-weak Magnetic Field
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.
