| 摘 要： | 研究采用自制内循环(IC)反应器,以实验室模拟废水为进水,接种城市污水处理厂的剩余污泥,对反应器的启动及运行过程进行研究,在经过污泥驯化、颗粒培养、调整及稳定的不同阶段连续运行.结果表明:启动初期反应器pH过低,产甲烷菌生长受抑制,导致VFA累积,容易酸化.通过改变模拟废水中微量元素的浓度及添加缓冲溶液,酸化的反应器可...

| Abstract: | With the influence of experimental simulated sewage and waste sludge from urban wastewater treatment plant for seed,a self-made internal circulation(IC) reactor was used to investigate the start-up and running process of IC reactor through stages of sludge acclimation,granule shape,modulation and stable running.Results showed that at the beginning of start-up,pH was so low that the methanogens was inhibited,resulting in VFA accumulation and acidification.By changing the concentration of trace elements and a... |
