- Abstract:
- 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.
