【摘要】 为了处理苯乙酸工艺过程中的废酸 ,并进行综合利用 ,对四川省天然气化工研究院苯乙酸车间的废酸进行了研究 ,在此基础上提出了一种适合该废酸体系的处理法—即真空浓缩后加氧化剂H2 O2 氧化法。用该法处理后的废酸因地制宜地加以利用 ,并通过实验进行了验证 ,效果较好。该方法工艺简单 ,可行 ,达到综合利用的目的 ,具有一定的科学性和适用性 ,对处理其它废酸体系提供了一条很好的思路。更多还原

【Abstract】 The treatment and the comprehensive utilization of the waste acid ,which is produced in the phenylacetic acid workshop of Sichuan Natural Gas Chemical Institute was studied. The method of concentrating in vacuum and adding the oxidant of H 2O 2 was used. It was found that this method is very effective . The technological process of this method is easy, feasible, scientific and practical. It provides a good train of thought for other waste acid system.更多还原
