| 摘 要： | 利用蒸发法对癸二酸生产过程含酚废水进行资源化处理. 结果表明,初始pH<10,苯酚蒸出率维持在34%,pH>13时,苯酚蒸出率接近0. 在碱性条件下获得的硫酸钠粉末呈黄色,且在pH为12.8时颜色最深,利用煅烧或N2环境下蒸发可消除硫酸钠粉末的颜色. 硫酸钠对酚的蒸出率影响较小,随苯酚初始浓度增加酚的蒸出率出现先增后减的趋势.

| Abstract: | The wastewater containing phenol and sodium sulfate was treated by evaporation method. The results show that when the initial pH value is under 10, the evaporation rate of phenol reaches 34%, and phenol is not evaporated when the pH value in solution is above 13. The powder of Na_2SO_4 is yellow under alkali condition and the chromaticity is the deepest at pH 12.8. There are some technologies to eliminate the color of Na_2SO_4, e.g calcination in air circumstances or evaporation in N_2 circumstances. Phenol evaporation process is insignificantly affected by solid sodium sulfate. |
