CuO/Al_2O_3-O_2降解偏二甲肼废水研究

Study on Degradation of UDMH Wastewater with CuO/Al_2O_3-O_2

偏二甲肼及其降解副产物有剧毒,在生产、运输和储存过程中产生的污水需要经过严格处理方可排放。使用一台微型固定床反应器,将O_2作为氧化剂,用CuO/Al_2O_3作为催化剂对偏二甲肼废水进行降解处理,通过正交实验研究了废液进料速率、O_2进气速率、反应温度和催化剂上Cu负载量对偏二甲肼转化率的影响。实验结果表明:偏二甲肼转化率可以达到99.99%。

UDMH and its degradation by-products are highly toxic, so the sewage produced in the process of production, transport and storage needs to be treated strictly before discharge. In this paper, a micro fixed-bed reactor was used, oxygen as the oxidant and CuO/Al2O3 catalyst to treat wastewater. Through the Orthogonal experiment, the effect of the rate of liquid, the rate of O2, temperature and the rate of Cu loading on catalyst on the conversion rate of UDMH is studied. The result shows the conversion rate of UDMH can achieve 99.99%.
