摘　　要：介绍了OCO的工艺原理，并根据物料平衡推导出其污泥龄与处理效率的关系，由此绘制出两者的关系曲线，最终得出OCO工艺适宜的污泥龄为6-14天．同时以丹麦的SPJALD污水处理厂为例进行工艺设计拟算，得出在相同处理效率条件下的污泥龄，从而证实了所推导出的污泥龄与处理效率关系的正确性．The principle of OCO craft was showed, and obtain a relation about the efficiency of process and sludge age according to the balance of materiel and supplies, from this draw a curve by their relation, at last received a suitable age of sludge about OCO craft, the range of it is about six to fourteen days. Simultaneously carries on the technological design take a sewage treatment plant of Denmark＇ s as an instance to calculate, and got a sludge age under the same efficiency of process, thus confirmed the accuracy of the relation about the efficiency of process and sludge age.

关 键 词：OCO工艺 污泥龄 处理效率
