摘要
地下式污水处理厂为地下封闭环境,通风除臭系统的设计尤为重要.以泰和污水处理厂为基础,构建了点源污染和面源污染两种空间模型,对不同排风口高度下模型内的流场分布和污染物浓度变化进行模拟,分析了大空间除臭风管排风口高度对于污染物排出效果的影响,总结了地下箱体大空间除臭系统设计的要点,为同类型除臭系统设计提出建议.
Abstract
Underground wastewater treatment plant(WWTP)is in an underground closed environment.Its design of ventilation and deodorization system is particularly important.Based on Taihe Wastewater Treatment Plant,two spatial models of point source pollution and non-point source pollution are built to simulate the changes of flow field distribution and pollutant concentration in the models under different vent heights.The influence of the vent height of the large-space deodorizing air duct on the pollutant discharge effect is analyzed,and the key points of designing the deodorizing system in the large space of underground box are summarized,which give the suggestions for the design of the similar deodorizing systems.
