Method for treating wastewater from the preparation of nitrobenzene |
| abstract |
The present invention relates to a method for treating alkaline wastewater, which is formed in a process of washing crude nitrobenzene obtained by nitration of benzene, wherein (i) the alkaline wastewater is deficient in oxygen The atmospheric pressure is heated under pressure, and then cooled and let down; (ii) the wastewater obtained in (i) is further purified by stripping of the stripping gas, and the vapor of the loaded impurity Extracting the gas stream and then cooling to a temperature of 10 ° C to 60 ° C; (iii) (ii) the liquid program product obtained by cooling the stripping gas stream of the supported impurities is separated into an aqueous phase and an organic phase, and the organic The phase is further used in the aniline manufacturing process. |
