摘要
为研究人工强化河道处理技术——生物接触氧化工艺处理河道污水的能力,实现治理条子河的目的,采用砾石和火山岩填料作为微生物载体并利用稀释后的生活污水模拟河道污水。对工艺的的挂膜启动进行了研究,分析了启动过程中的生物相及对COD、NH4+-N的去除效果。结果表明,在水温11～16℃时,2个反应器启动30 d时,对COD和NH4+-N、TN的去除率分别稳定在80%和70%、50%以上,且生物相趋于稳定时,标志着系统启动成功。
Bio-contact oxidation process was used to simulate urban rivers and realize the treatment of Tiaozi river. Taking diluted domestic wastewater as the influent and using gravel and lava as the carrier of microorganism to design the reactors. The changes of biofacies and the treatment efficiencies of COD, NH4＋-N and TN were analyzed. Experimental results show that： after 30 d, under the condition of the water temperature of 11 -16 ℃, the removal rate of COD and NH4＋-N, TN was stable at 80% and 70%, 50% respectively, and the biofaceies were steady, so the system was startup successfully.
