CASS法工艺在某高校生活污水处理中的应用

Application of CASS(Cyclic Activated Sludge System) techniques for domestic wastewater

采用地埋式水解调节池———CASS法处理某高校新区二期工程生活污水。利用调节池的工作特性,在部分空间分段设置生物填料,利用污泥无动力回流,强化污水的水解与除磷。池顶绿化,无地面构筑物。整个系统采用PLC集中控制自动运行,无人值守。经技术经济分析,污水处理成本 0 452元 /m3,投资指标 860元 /m3。此外,还考虑了处理系统的扩容、污泥和尾气处理、噪声控制、消毒和回用方案。

The domestic wastewater in one university is treated by the anaerobic hydrolysis acidification in the adjusting tank -CASS (Cyclic Activated Sludge System) techniques in the underground. According to the working condition of the adjusting tank, in it is installed the bio-packing in parts and the returning of the activated sludge is finished depend on gravity for the enhancement anaerobic hydrolysis acidification and dis-phosphorus of the wastewater. ON the tank tope make green by planting and there is no any structures. The system is controlled by the PLC and automatic operated. Based on analysis of technology and economic, treatment cost is 0.21 yuan/m^3 and investment index is 860 yuan/m^3。In addition, the contents of scale-up, sludge, waste gas, noise control, disinfection and reclaim are considered.
