设计并构建了生物吸附-微滤膜反应器,利用活性污泥的吸附作用及微滤膜的高效分离作用,处理来自不同生活污水处理厂的进水,分析典型城市污水中碳源物质的形态分布,以及生物吸附-微滤膜反应器对生活污水中含碳物质的富集分离效果.结果表明,生物吸附-微滤膜反应器对胶体COD的去除率较高,为60％～ 76％,对溶解态COD的去除率较低,为29％ ～ 38％;不同HRT对反应器的运行效果影响不大,综合考虑COD富集率及系统运行的经济性,本研究推荐的运行参数为SRT=2 d,HRT=22 min,藉此,生物吸附-膜反应器对碳源物质的富集回收率可达到50.0％左右.“,”An adsorption-microfiltration membrane (MF) separation system was developed based upon adsorption and membrane separation principles for carbon source recovery from municipal wastewater of different wastewater treatment plants.The results showed that the reductions in chemical oxygen demand (COD) following treatment with the adsorption-MF system were mainly due to the removal of colloidal COD (60％ to 76％),while the removal of soluble COD was less extensive (29％ to 38％).Different hydraulic residence times (HRT) generally did not affect the performance of the system.Considering the carbon source recovery rate and the economic costs of system operation,the optimized parameters of the adsorption-MF separation system were set as follows:sludge retention time (SRT) of 2 d,HRT of 22 min.This process showed good performance in relation to quickly trapping and concentrating influent COD,and the recovery rate of the system could reach up to around 50％.
