沈阳满堂河污水处理厂最佳回流比与曝气量研究

Study on the Best Sludge Recycle Ratio and Aeration Intensity of Shenyang Mantang River Wastewater Treatment Plant

检测代表性的5个水质指标:氨氮(NH3-N)、总磷(T-P)、化学需氧量(COD)、生化需氧量(BOD5)、固体悬浮物(SS)的去除率,确定沈阳市满堂河污水处理厂最佳的污泥回流比与最佳曝气量.结果表明:回流比为75%,曝气量为34 kg/h时,各指标的去除率达到最大,即污水处理的效果最佳.

Five representative water quality index are measured： the removal efficiency of NH3-N, T-P, COD, BOD5, and SS. The best sludge recycle ratio and aeration intensity of Shenyang Mantang River wastewater treatment plant were confirmed. The result show when sludge recycle ratio was 75 % and aeration intensity was 34 kg/h, the removal efficiency of each index was the highest, namely effect of wastewater treatment was the best.
