摘要
生物接触氧化工艺主要由两大系统组成 :填料和曝气。本文结合东深供水源水生物接触氧化预处理这个前所未有的特大型水处理工程的有关试验研究 ,介绍其水力摩阻问题以及其试验研究的方法 ;根据实测的流速分布和填料挂泥的重量 ,分析了生物处理池的水力特性和填料挂泥对工艺处理效果可能产生的影响 。
The biological contact aeration technology, as a novel technology for sewage disposal, has been studied and applied to water supply source pre treatment in recent two decades. The technology consists of two parts, the filling and the aeration. In the project of water pre treatment with this technology for the East River Shenzhen water supply source, a series of tests have been conducted. This paper presents the experimental techniques and results on the problem of flow drag in the biological contact aeration process. According to the measured velocity distribution and the weight of silt deposited and gathered on fillers, hydrodynamic characteristics in the channel of biological treatment were analyzed, and their possible influence on the effectiveness of wake pre treatment was examined.
