Abstract:Objective To design and manufacture exhaust treatment equipment for laboratory animal facilities and determine its actual effectiveness. Methods The exhaust treatment equipment was developed and manufactured based on both MnOx?TiO2 photocatalysis and gas?liquid turbulence. On the roof of a laboratory animal facility in Xian, the equipment was evaluated regarding the capacities for NH3 , H2 S, and stench clearance according to national standards. Results The equipment clearly decreased the concentrations of NH3 , H2 S, and stench at both boundary and exhaust port. Conclusions The exhaust treatment equipment based on photocatalysis and gas?liquid turbulence effectively eliminated the main odorous pollutants exhausted by laboratory animal facilities.
