由于臭氧紫外灯可以有效地降解磷化氢，通过对3个温度（20℃、25℃、30℃）、4个相对湿度（33％、53％、75％、85％）、3个磷化氢初始浓度（100、200、400 m l／m3）、3种臭氧紫外灯功率（40、80、120 W ）条件下，反应箱内磷化氢浓度进行检测，研究其对储粮中磷化氢降解速率的影响。结果表明，反应箱内温度越高、相对湿度越低、臭氧紫外灯功率越大、磷化氢初始浓度越低，磷化氢降解反应速率越快；但随着磷化氢降解的进行和磷化雾的大量产生，会使臭氧紫外灯对磷化氢降解反应速率的影响变弱。因此，适当提高环境温度、降低其湿度、控制磷化氢初始浓度、增加臭氧紫外灯的功率以及合理布置臭氧紫外灯，对降解磷化氢有利。

Phosphine gas can be effectively degraded by ozone ultraviolet lamp . The test conditions included 3 kinds of temperature (20 ,25 and 30℃) ,4 kinds of relative humidity (33% ,53% ,75% ,85% ) ,3 kinds of initial phosphine concentra‐tion (100 ,200 ,400 ml/m3) ,and 3 kinds of ozone ultraviolet lamp power (40 ,80 ,120 w) .The concentration of phosphine was detected to study its effect on the degradation rate of phosphine in stored grain .The results showed that :in the reaction tank , when the temperature and ozone ultraviolet lamp power was elevated ,the relative humidity and initial phosphine concentration was lower ,the phosphine degraded faster .In the process of degradation of phosphine ,with phosphating fog adding up ,the effects of the temperature ,relative humidity ,phosphine initial concentration ,ozone ultraviolet lamp power on phosphine degradation rate were weaker .Therefore ,the effective methods were to improve the reaction temperature ,reduce the relative humidity ,control phosphine initial concentration ,increase ozone ultraviolet lamp power appropriately and distribute ozone ultraviolet lamp installation position reasonably .
