UV除臭净化装置在实验室废气处理中的模拟应用

Application of UV Deodorization Device in Waste Gas Treatment in the Laboratory

实验采用紫外照射产生臭氧氧化降解有毒废气的方法。气体检测过程采用大气采样器对废气进行吸附,活性碳做吸附剂,吸附后活性炭采用甲醇进行解吸,解吸后液体采用高效液相色谱仪进行检测。解吸后液体检测波长为254 nm,流速为1 mL/min,观察检测前后气体中有害物质的含量。实验结果表明,废气中有毒有害气体的去除率均达到70%,处理后废水基本趋于无味的状态。

In the lab, poisonous waste gas was prepared by oxidative degradation with ozone in ultraviolet radiation; the air sampler with activated carbon as adsorbent was used to adsorb the poisonous waste gas, and then desorption was carried out in methanol. At last, high-performance liquid chromatography was used to detect the desorption solution under the conditions of detection wavelength 254nm and flow rate 1mL/min. Experimental results show that the removal rate of toxic and hazardous gas can reach to 70%, treated wastewater basically become tasteless state.
