AOR工艺的设计研究

AOR是传统活性污泥法与氧化沟结合的一种新型生化反应器。具有较高的脱氮除磷功能,同时独特的污泥恢复区的设计,使得回流污泥集中适当充氧,另外采用同心圆结构,使每个区形成循环流态,因此是一种高效、节能、适应性强的污水处理工艺。在对AOR反应器分析研究的基础上,提出满足生物脱氮除磷的动力学设计研究方法,并对其设计计算公式进行推导。

THE RESEARCH ON DESIGN OF AOR PROCESS

AOR is a new biochemical process that combines with traditional-activated sludge process and oxidation ditch.It has better function of nitrogen and phosphorus removals,and its unique design of sludge renewal region,makes the return sludge centralized with appropriate oxygenation,meanwhile each region can engender flow state with concentric circles adopted.Accordingly,it is a sort of water technology with high efficiency,energy saving and better accommodation.After the study of AOR process,the dynamic design meeting biological phosphorus and nitrogen removal is proposed, and the formulas used to design and calculate are deduced.
