摘要
采用渠式生化反应器、交替好氧缺氧工艺处理城市污水 ,当水力停留时间为 1 0 h,空气阀开闭周期为 3 0 / 3 0 min时 ,COD的去除率达 86.8% ,T-N的去除率达 63 .6%。在相同的反应条件下 ,流速对处理效果的影响不大。试验结果表明利用污水渠处理城市污水在技术上是可行的。
A canal bioreactor was designed and alternating aerobic-anoxic process was employed to dispose of urban wastewaster.when the hydraulic retention time-air on/off period were bept at 10h and 30/30min respectively,86.8% of COD and 63.6% T-N were removed.The influence of velocity of flow was discussed,the results indicated that velocity of flow had no obvious effects on treatment performance,the research results also showed that canal bioreactor was technologically suitable for treating urban wastewater.
