废膜炭吸附去除废水中典型污染物的性能研究
Performance Study of Carbon Adsorption of Spent Membranes for the Removal of Typical Pollutants in Wastewater
摘要
Abstract
Organic polymer membranes have been widely used for wastewater treatment.Due to occurrence of irreversible membrane contamination,the replacement of the membrane after the performance decay leads to the generation of a large number of discarded membranes.How to realize the reuse of these waste polymer films has important economic and environmental value.In this study,a carbonaceous material with both ultramicroporous,mesoporous,and macroporous structures was prepared by a simple pyrolysis remodeling reaction using waste hollow fiber membranes as a template.The differences in the adsorption performance of the waste membrane-derived activated carbon and commercial activated carbon were investigated based on the structural characterizations of the carbonaceous materials.The kinetic and thermodynamic processes for the adsorption removal of typical aromatic hydrocarbon organic contaminants and antibiotics from water were investigated.It was found that the the waste membrane carbon with hierarchical pore structure had a higher removal capacity for aromatic hydrocarbon organic pollutants than commercial carbon,while the adsorption performance for antibiotics such as ciprofloxacin,carbamazepine and sulfadiazine was lower than that of commercial carbon.关键词
