Effects of Influent Flow Distribution Ratio on Nitrogen Removal in Step-Feed A/O Process
流量分配对分段进水A/O工艺脱氮性能的影响

In order to optimize the utilization of influent carbon source,a feeding pattern so-called "coefficient of influent flow rate" was adopted in a pilot-scale step-feed A/O process treating domestic wastewater.The effects of influent flow distribution ratio on nitrogen removal efficiency were investigated when the reactor was operated at different loading rates and COD/TKN ratio of 3,5,7,9,11,13,respectively.The experiment results indicated that the wasting of nitrification capacity occurred when high loading ...
