摘要
采用缺氧池、需氧池和间隙曝气池组合工艺生化法处理高浓度氨氮废水——ADC发泡剂.试验表明,在温度为28℃,pH值为7.4～7.8,C/N为5,回流比R为200%和r为150% 时,NH3-N去除率可达92.75%;NH3-N负荷对NH3-N的去除率有较大的影响,应低于0.12kg/（m^3·d）。
ADC foaming agent, the wastewater with high concentration of NH3-N, was treated by a biochemical method including aerobic and anaerobic tank and interval aeration tank. Results show that the removal efficiency of NH3-N can reach 92.75 % when temperature is 28 ℃, pH value is between 7.4 and 7.8, C/N is 5, and the reflux ratios R and r are 200% and 150%, respectively. The load of NH3-N has great effect on the removal rate of NH3-N, and for better treatment, the load should be less than 0.12 kg/（m^3 ·d）.
