Study of Electroplating Wastewater Treatment by Magnetoelectric Oxidation Biological Filter

Abstract:

In this study, a magnetlectric oxidation biological filter (MOBF) was investigated for the removal of organic pollutants, heavy metal ions and cyanide ions in electroplating wastewater. The influencing factors including the inlet water flow, external DC voltage, aeration rate of the MOBF on wastewater treatment performance were studied. Data analyses show that with iron-carbon tube as the core component, the MOBF’s removal rate for COD, Cr6+, Cu2+, Zn2+ and CN- were 93%, 99.99%, 99.7%, 96% and 99%, respectively. The best treatment conditions for the MOBF were as follows: the inlet and outlet pH value of 3.5 and 8.5 respectively, the external voltage of 3.8V. When the inlet wastewater flux is 40L/h, the aeration rate is 1m3/h.
