催化氧化法处理对硝基苯胺废水

Treatment of Waste Water in Production of p-Nitroaniline by Catalytic-Oxidation

研究了催化氧化法处理对硝基苯胺废水，通过试验发现催化剂、氧化剂用量分别为0．10％-0．20％和0．20％～0．40％，反应时间为5-8h，处理后废水达到国家二级标准排放。

The study on treatment of waste water brought in the process of producing p - nitroaniline is introduced. It shows that the effluent meet Grade Ⅱ discharge standard when the following treatment conditions is used： levels of catalyst 0.10% -0.20% ; levels of oxidant 0.20% -0.40% , reaction time 5 8 hours.
