不同曝气控制方式对SBR短程硝化特性的影响
Effect of Different Aeration Control Mode on Characteristics of Shortcut Nitrification in SBR Process
摘要
Abstract
In this experiment,under the conditions of temperature of 30+ 1 ℃ and pH value of 7.9 to 8.2,the shortcut nitrification characteristics of low C/N urban wastewater are researched by the control modes of constant blast volume [0.4m3空气/(m水 · h)]and constant DO (0.5 mg/L) of continuous aeration.The results showed that the time required for the constant aeration mode [0.4 m3空气/(m3水 · h)] was significantly less than that of the constant DO(0.5 mg/L) aeration control mode to achieve stable short cut nitrification.And NO2-N accumulation efficiency of constant aeration reached to 95％,which was higher than the rate of 85％ for constant DO (0.5 mg/L) aeration control.In addition,the time of shortcut nitrification aeration with constant aeration [0.4 m3空气/(m3水 · h)]should be controlled to 4 h,while the mode of constant DO (0.5 mg/L) should be at 3 h.关键词
