【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.更多还原

【Abstract】 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.更多还原
