Study on Influence of Air Outlet Height on Pollutant Discharge in Underground Large Space
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.
