采用ICEAS工艺进行瓦房店市污水处理厂设计

Design of Wafangdian Wastewater Treatment Plant with ICEAS Process

在调研的基础上 ,成功地应用ICEAS (IntermittentCyclicExtendedActivatedSludge)工艺进行瓦房店市污水处理厂设计。实践证明 ,该工艺具有占地面积小、处理效果好、工艺简单、运行稳定、对污水水质适应性强、耐冲击负荷、污泥龄长、污泥沉降性能好、剩余污泥少等优点。

Based on the investigation, the design of the wastewater treatment plant in Wanfangdian city, Liaoning Province was completed employing ICEAS(Intermittent Cyclic Extended Activated Sludge)process. It has been proved from the operational practice that the process has lots of advantages as compared with both conventional activated sludge process and SBR, such as less footprint, good operational performance, simple process, stable operation under conditions of high variation of wastewater quality with peak load and longer sludge age. Besides, the settling characteristic of activated sludge is good with less surplus sludge produced and so on.
