Abstract :
The paper studied the treatment technology of high concentration emulsion wastewater in metal machining plant. By analyzing the properties of emulsion wastewater, we used the combination process of membrane technology+Fe-C micro-electrolysis+membrane bioreactor to treat the wastewater. Through the ceramic membrane, The removal rate of CODCr can reach 95%. Fe-C micro-electrolysis treatment can improve the biodegradability of wastewater, lastly through the membrane bioreactor treatment systems, CODCr of the effluent is less than 100mg/L, which meets the requirements of The First Grade of the National Discharge Standard (GB89781996).
