| Abstract: | The paper through to the PCB（Printed Circuit Board） ink wastewater,with orthogonal test and single factor test optimization test parameters,aeration micro electrolysis process is proposed for this kind of wastewater pretreatment,and obtained the optimum parameters： the ratio of iron/carbon was 1∶1,pH 3.0,60 min of reaction time,ratio of gas and water was 15∶1.The CODCr removal rate can reach about 60 %,B/C ratio raised from about 0.15 to about 0.35,heavy metals and other indicators below the limit of detection. |
