Research progress of application of modified plant fiber in oily wastewater treatment
Modified plant fiber is regarded as a kind of efficient oil adsorption material and has made some achievements in the treatment of oily wastewater.A variety of modification methods of plant fi-ber were reviewed,including dip coating,sol-gel technique,in situ synthesis,spraying coating,hy-drothermal method,plasma method,chemical vapor deposition and other methods.The oil-water separation capacity and separation efficiency are compared before and after the modification,and the mechanism of the improvement of oil absorption is expound after the modification.Finally,future out-looks and challenges faced in development of modified plant fiber for oily wastewater treatment are discussed.
