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.
