摘要
对沥滘污水处理厂进行三期扩建工程,处理规模为25万m^3/d,并对一、二期工程50万m^3/d规模进行提标改造。三期扩建工程采用深度脱氮改良AAO工艺,一、二期提标改造工程采用生物滤池工艺,污泥处理采用低温热干化。介绍了污水处理厂全地下集约组团化层叠布置、工艺流程和主要构筑物的设计情况,并对主要设计特点和新技术的应用进行了分析。
The capacity of the PhaseⅢ extension project of Lijiao WWTP was 25×10^4 m^3/d,and the scale of 50×10^4 m^3/d of PhaseⅠand PhaseⅡ Project was upgraded.The improved AAO process with advanced denitrification was used in the Phase Ⅲ extension project,and the biological filter process was used in PhaseⅠ and PhaseⅡ upgrading project.The low temperature thermal drying process was used for sludge disposal.The underground intensive grouping arrangement,treatment process and main structures were introduced in the paper.The main design characteristics and new technology were analyzed.
