| Abstract: | By comparing of several kinds of method for treatment of aniline wastewater, an extracting method using methylbenzene as extracting agent was proposed for the treatment of 40 g/L aniline wastewater produced in the manufacture of rubber antioxidant （RD）. Based on the technological parameters obtained from experiment, a production facility whose capacity was 20 m^3/d was designed. The production showed that 98.5 % of aniline was recovered. Compared with other means, the proposed extraction method has advantages such as less equipment investment, easier operation and lower consumption. |
