摘要
以太湖蓝藻水为主要处理对象,研究阳极区pH值对沉积型微生物燃料电池(Sediment Microbial Fuel Cell,SMFC)运行特性的影响.结果表明,SMFC系统阳极的碱性条件有利于功率密度的提高及污染物的去除.阳极初始pH值为5.5和8.5时,系统稳定运行功率密度和COD、VSS的去除率分别为3.5mW.m-2、7.3%、4.2%和5.4mW.m-2、11.5%、9.2%.系统功率密度与污染物去除率呈正相关,污染物去除率越大,系统功率密度越高.
Taken cyanobacteria from Taihu Lake as fuel of SMFC system,the influence of anodic pH value on the SMFC performance was investigated.The results showed that high pH values in anodic area were beneficial to the increase of power density and pollutants＇ removal in carbon felt SMFC. When pH value in anodic area was 5.5 and 8.5,the steady power density,COD and VSS removals were 3.5 mW·m^-2,7.3%,4.2% and 5.4 mW·m^-2,11.5%,9.2%,respectively. The power density was proportional to the pollutant removal. The more the pollutant removal,the higher the power density.
