多孔陶瓷滤料的亲油改性及其除油性能
Lipophilic modification of porous ceramic filter media and its oil removal performance
摘要
Abstract
The orthogonal experiment was used to optimize the modification process.Before and after modification,filter media were characterized by FTIR,SEM,density,porosity and contact angle.The results showed that the best modification parameters included aluminate coupling agent(5%),temperature(90℃),modification time(20 min) and coating times(one).Proofs of porous ceramic filter media successfully modified included the characteristic adsorption peaks of CH3 and CH2 in FTIR from modified filter media,reduction of the density and porosity and increase of the contact angle to water.At a speed of 15 m/h and after 20 min,and oil removal rate of modified filter increased from 96.46% to 65.18% compared with pretreatment filter.The breakthrough curves showed that the working times of original,pretreatment and modified filter media were 48,85 and 149 min,respectively,which implied that operation cycle of modified filter was 101 min and 64 min longer than those of original and pretreatment filter.The oil removal rate of 90% lasted for 45 min,which means that the modified filter is a good coalescence degreasing material.关键词
