摘要
在竖流式沉淀池和辐流式沉淀池的基础上,提出了一种新型高效竖流式沉淀池,它既克服了原有沉淀池配水、集水不均等弊病,又继承了竖流式沉淀池接触絮凝和污泥悬浮层拦截等许多优点,并把最大池径由传统的竖流式沉淀池池径的8 m提高到高效竖流式沉淀池的25 m以内,其沉淀效率比传统沉淀池提高40%以上,非常适用于中小型污水处理系统。
On the basis of vertical sedimentation basin and radial sedimentation basin, a new type of high efficient vertical sedimentation basin was put forward,it overcome the disadvantages of the existing sedimentation basin, such as uneven water distribution and catchment, and it also inherited many advantages of vertical sedimentation basin,such as the contacting of basin to flocculation and intercepting of sludge blanket,and the max basin diameter was increased from 8 m of conventional vertical sedimentation basin to 25 m of high efficient vertical sedimen- tation basin,and its sedimentation efficiency was also increased by more than 40% compared with the conventional sedimentation basin, and it was very suitable for medium and small sized sewerage treatment system.
