| 摘 要： | 以垃圾渗滤液为阳极液,系统研究了汲取液种类和浓度对正渗透微生物燃料电池(OsMFC)工艺处理垃圾渗滤液性能的影响.结果表明,在汲取液为氯化钠的情况下,OsMFC工艺的最大功率密度可达0.44 W·m~(-2),表观内阻为236.75Ω,水通量为0.98 L·m~(-2)·h~(-1),TOC、NH_4~+-N、TN和TP的去除率分别达到89.51%、93.27%、94.01%和96.95%,均好于碳酸氢钠和碳酸氢铵作为汲取液时的处理效果.此外,氯化钠汲取液浓度越大,产电性能越好,表观内阻越小,水通量越大.产电性能随汲取液浓度的增大变化不大,在汲取液浓度为1 mol·L~(-1)的情况下,水通量和盐返混量的比值最大,处理效果最好.

| Abstract: | Effect of types and concentrations of draw solutions on the treatment of landfill leachate by osmosis microbial fuel cell (OsMFC) was systematically studied using the leachate as theanodic solution. Experimental results indicate that the OsMFC could achieve maximum power density of 0.44 W·m-2,apparent internal resistance of 236.75 Ω,water flux of 0.98 L·m-2·h-1,89.51% of TOC removal,93.27% of NH4+-N removal,94.01% of TN removal,and 96.95% of TP removalwhen employing sodium chloride as draw solution,which performed much better compared with that of sodium bicarbonate and ammonium bicarbonate. Furthermore,the power generation and water flux increased,while the apparent internal resistance decreased,with the increasingdraw solution concentration. The power generation performance change little with different draw solution concentration,and 1 mol·L-1 was identified as optimal draw solution concentration due to the maximum ratio of water flux with reverse salt flux. |
