The Research on the Optimal Coagulant in Oily Wastewater Treatment using Flat Ceramic Membrane Filtering Device

Membrane separation technique has a beneficial effect when applied to remove dispersed oil,emulsified oil and dissolved oil,the removal rate is more than 95%,meanwhile there is no secondary pollution, and separation process is without phase transformation, at the same time the membrane module structure is simple,and it has a short process,meanwhile the equipment also consumes low energy[1]. We use flat ceramic membrane filtering device adding coagulant to dispose oily wastewater.To choosing coagulant,we do an experiment in motionless beaker with FeCl3,PAC,PAM and two combinations of them to investigate the effect of oily wastewater treatment.Meanwhile,to provide a scientific basis for oily wastewater,we perform univariate analysis on optimal pharmacy to gain the most suitable technological parameters of oily wastewater treatment.
