摘要

  • 摘要: 高浓度DOP生产废水生物毒性强,采用常规手段难以有效处理,对环境存在较高危害性。采用树脂吸附技术预处理增塑剂DOP生产废水,考察了树脂吸附与脱附的最佳工艺条件,结果表明,采用NDA99吸附树脂,在室温、吸附pH=2、吸附流速4 BV/h条件下,每批次处理量16 BV,COD去除率可达94%以上;对吸附饱和的树脂采用1 BV 8%NaOH +1 BV 4%NaOH+2 BV 水,在60℃下以1 BV/h的流速进行脱附,COD脱附率超过97%,树脂的吸附-脱附性能良好。
    Abstract: High concentration DOP wastewater is very difficult to be degraded by conventional treatments and leads to serious harmful to the environment. In this study, resin adsorption was used to pretreat DOP wastewater. The optimal operating conditions for resin adsorption and desorption were investigated. The results showed that the COD removal rate with resin NDA99 reached to 94% under the conditions of room temperature, pH=2, flow rate of 4 BV/h and batch processing volume of 16 BV. The desorption agent of 1 BV 8%NaOH+ 1 BV 4%NaOH+ 2 BVwater was used to regenerate the saturated resin under the conditions of 60℃ and desorption flow rate of 1 BV/h. The COD desorption rate was over 97%. The resin exhibited the better adsorption and desorption characteristics.
