摘要
由于太湖水质呈现高藻、高有机物、高氨氮的"三高"特征,常规处理对原水中藻类、氨氮、有机物等的去除效果较差,因此充山水厂实施了深度处理工程。经试验比较,在水厂原有气浮、过滤的常规处理工艺基础上,增设了BIOSMEDI(生物滤池及臭氧—生物活性炭滤池等深度处理单元。介绍了充山水厂生物预处理—气浮—臭氧/生物活性炭—砂滤—消毒组合工艺的流程、设计参数及设计特点。
The Tai Lake water was characterized with high content of algae, organics, and ammonia, which could not be effectively removed by the traditional treatment processes. The advanced treatment methods were used in Chongshan Waterworks. After the test comparison, the advanced treatment units, including BIOSMEDI biological filter, 03 - BAC filter and so on, were added based on the existing conventional treatment processes of DAF and sand filtration. The flow, design parameters, and design characteristics of the combined process of biological pretreatment/DAF/O3 - BAC/sand filter/disinfection were introduced.
