Abstract:Cold rolling wastewater treatment most difficult in the metallurgical sewage wastewater, Its water quality complex composition, high concentration, stable, difficult degradation, water quality varies significantly, especially oil pollution of complex components of high concentration of oil wastewater, Need to use technology to achieve outstanding specific standard treatment, in order to achieve green development of metallurgical processes. Introduces the ultra filtration oil removal technology applied to oil emulsion wastewater treatment in a cold-rolled. infinite ceramic ultra filtration is adopted to improve the oil removal in this paper, With the aid of ultra filtration loops,reduce the oil content of wastewater. Ultra filtration water production oil in 20 mg/L, oil removal rate is more than 96%, operation cycle can be up to 10 days, the overall effect is better. The operation control of the system, chemical cleaning and membrane pollution prevention and control are studied, find out targeted operation control parameters and membrane pollution prevention and control measures, and realization of ultra filtration in the cold rolling thick oil wastewater in a stable and good application effect.
