摘　　要：针对现有初沉池密闭除臭通风优化方案的不足,提出了一种一体化密闭通风方案。基于初沉池实际几何特征和优化方案,利用相似模型建立了相似模型实验台,并进行了密闭隔绝性能和臭气抽吸去除率等关键参数的测试分析。结果表明,初沉池内实现最低2.8 Pa的负压即可保证密闭抽吸效果,搅拌和非搅拌工况对密闭效果的影响不显著。抽吸风量影响臭气去除率,两者呈反比关系,低抽吸风量即可满足对臭气去除率的要求,从而降低系统臭气处理成本与运行能耗。An integrated closed ventilation scheme was proposed to solve the shortcomings of the existing closed deodorization and ventilation optimization scheme in primary sedimentation tank. Based on the actual geometric characteristics and optimization scheme of a primary sedimentation tank, a similar model experimental platform was established by using similar model method, and the key parameters such as sealing isolation performance and odor removal efficiency were tested and analyzed. The minimum negative pressure of 2.8 Pa in the primary sedimentation tank could ensure the sealing suction performance, and the influence of stirring and non-stirring on the sealing was not significant. Air volume affected the odor removal efficiency, and there was an inverse relationship between the two. A low air volume could meet the requirement of odor removal efficiency, thus reducing the operation cost and energy consumption.
