| 摘 要： | 研究了树脂吸附法处理3,6-二氯水杨酸生产废水的工艺过程。结果表明,NDA-77吸附树脂对该废水具有良好的吸附-脱附效果。经树脂吸附处理,废水中主要有机污染物2,5-二氯苯酚和3,6-二氯水杨酸均得到去除,总有机碳(TOC)由210mg/L降为20mg/L以下,吸附饱和的树脂可采用稀碱液实现完全再生。经吸附处理去除有机物后,废水中含有20%的KCl,可进入工厂现有的KCl隔膜电解装置,用于KOH的生产。

| Abstract: | In this paper,the macroporous polymeric resin NDA-77 was employed to treat 3,6-dichlorosalicylic acid production wastewater and showed good properties of adsorption and desorption.After adsorption process,2,5-dichlorophenol and 3,6-dichlorosalicylic acid,the two main organic pollutants in the wastewater,were removed completely.The concentration of TOC is about 210 mg/L in the wastewater,but less than 20mg/L in the treated effluent.Those effluent still achieving remaining about 20% KCl electrolyte and is recommended to apply to diaphragm electrolysis.Meanwhile,dilute sodium hydroxide could be used as a solvent for complete regeneration of the spent adsorbent. |
