RESEARCH ON OIL REMOVAL TECHNOLO-GY BY ORGANIC METAL ULTRAFILTRATION MEMBRANE
Organic metal ultrafiltration membranes have good hydrophilicity and hydrophobicity during oil-water separation and filtration,which make them resistant to pollution and less prone to clogging.In the oil removal experiment conducted by using organic metal ultrafiltration membrane,the oil removal device using organic metal ultrafiltration membrane can oper-ate stably for more than one month at a membrane flux of 30LMH,and the average removal rates of petroleum and SS are 76.8％and 76.6％respectively.The pro-duced water for petroleum and SS is stable and meets the standards,with the highest being only 10.3mg/L and 23mg/L respectively,which is nearly 50％lower than the effluent indicators required by the air flotation pro-cess.The operation difficulty of the oil removal device using organic metal ultrafiltration membrane increases at a membrane flux of 40LMH.The combined cleaning of CEB and CIP can effectively extend the stable oper-ation cycle of the membrane and ensure the stable op-eration of the system.The organic metal ultrafiltration membrane process can replace the traditional air flota-tion treatment process at a membrane flux of 30LMH.
