摘要

研究了陶瓷膜+树脂的组合工艺作为碱减量废水的处理方法,采用陶瓷超滤膜对废水中的SS和非溶性的对苯二甲酸等有机颗粒进行过滤回收,产水中SS≈0,CODcr去除率约20%。然后采用大孔树脂吸附废水中残余的对苯二甲酸等有机物,废水的可生化性由0.15提高至0.45,可解决碱减量废水常规采用高级氧化处理工艺费用太高和厌氧处理工艺产生恶臭气体的问题。
        In this study, the ceramic membrane and resin adsorption process was employed to treat alkali-minimization wastewater from printing and dyeing. The results showed that SS and insoluble organic particles, such as terephthalic acid, was recovered by ceramic membrane filtration with SS≈0 in the effluent, and CODcrwas removed by20%. The residual organic particles, such as terephthalic acid, was adsorbed by microporous resin, and BOD/COD of the wastewater improved from 0.15 to 0.45. The treatment process showed preferable environmental and economic effectiveness due to its low cost and no secondary pollution.
