交替式活性污泥法工艺研究与应用进展

交替式活性污泥法是近年来发展起来的一种新的污水处理工艺，它在一个反应器或一组反应器中通过时间或空间的交替实现对污水的处理。从最基本的形式到后来的各种变形，交替式活性污泥法工艺在控制系统、运行模式上都发展迅速。文章首先给出了交替式活性污泥法的特点，并在此基础上分别对三沟式氧化沟、UNITANK工艺、交替式内循环活性污泥工艺（AICS）和五箱一体化活性污泥工艺这几种典型的交替式活性污泥法进行了概述，最后提出了交替式活性污泥法的问题和其发展方向。交替式活性污泥法工艺是一种高效、经济、灵活的污水处理工艺，具有很好的应用前景。

Study and Development of the Alternating Activated Sludge Process

Alternating activated sludge process is a newly developed process of wastewater treatment. It completes the treatment in a single reactor or a group of reactors by time and spatial alternation. From the primitive forms to the later modified forms, ahernating activated sludge process has made rapid progress in control system, running mode and so on. In the first part,this paper introduces the characteristics of this process. On the basis of them, the specified process such as the triple oxidation ditch, UNITANK, the alternated internal cyclic system, and the five - tank integrated activated sludge system are summarized. There is also a prospect about the alternating activated sludge process in the last part, which points out that future research emphasis of alternating activated sludge process should be laid on the optimization of process combination. Simultaneously, corresponding equipment should be developed to improve the reliability. The alternating activated sludge process is a wastewater treatment process with high efficiency, low cost and great flexibility, which enable it to promises well.
