组合工艺去除垃圾渗滤液中的DBP和DEHP
Removal of DBP and DEHP in combined landfill leachate treatment process
摘要
Abstract
The removal efficiency and mechanism of di-butyl phthalate （DBP） and di-（2-ethylhexyl） phthalate （DEHP） in laboratory scale combined landfill leachate biotreatment process （UASB （Up-flow Anaero- bic Sludge Bed） ＋ BAF （Biological Aerated Filter） ＋ ANO （Anoxic） ＋ MBR （Membrane bioreactor） ） were studied. The influent concentrations of DBP and DEHP were 164.4 μg/L and 215.0μg/L, respectively, which were reduced to 11.8 p.g/L and 10.4 μg/L, respectively in the effluent, and their removal rates were up to 92.9% and 95.2% , respectively. DBP could be gradually removed during the combined process, and the prin- ciple mechanism should be the degradation by microorganism. MBR was the major process to remove DEHP, in which the removal efficiency was 56.6% mostly owing to the effect of membrane retention. The suggested com- bined biotreatment process was efficient in simultaneous removal of DBP and DEHP in landfill leachate.关键词
