| 摘 要： | DAT-IAT工艺是在满足连续进水的情况下，将连续曝气池DAT与间歇曝气池IAT串联而成的一种新的污水处理工艺方法。本研究以DAT-IAT工艺为基础，在DAT-IAT池进水处设置一厌氧生物选择器增强其除磷功能，以影响厌氧选择器生物除磷最为重要的三个操作参数为试验变量，即回流比、生物选择器体积比（R）以及进水易生物降解COD，研究厌氧生物选择器厌氧除磷的规律。

| Abstract: | DAT IAT process is an innovative sewage disposal method in which the demand aerobic tank(DAT)is connected with the intermittent aerobic tank (IAT)in series under the condition of sewage entering into the DAT IAT continuously.On the basis of DAT IAT process an anaerobic biological selector is set at the influent entrance of the DAT IAT tank to enhance the phosphorus removal efficiency. The phosphorus removal rule of the anaerobic biological selector is studied,taking three important operating parameters,i.e.recirculation ratio,biological selector volume ratio and easy biodegradation COD in sewage as the test variables which affect the biological phosphorous removal by the anaerobic selector. |
