| 開展了萃取-大孔樹脂吸附法處理辛醇廢堿液的實(shí)驗(yàn)研究，結(jié)果表明：以辛醇為辛醇廢堿液的萃取劑，在pH=3、辛醇與廢堿液體積比為0.5和萃取級數(shù)為2的條件下，當(dāng)進(jìn)水ρ(COD)為104651mg/L時，出水ρ(COD)降至6453mg/L以下，COD去除率達(dá)到93.8%以上，萃取劑辛醇可以重復(fù)利用；以辛醇二級萃取出水為進(jìn)水，HYA-106大孔吸附樹脂較佳的吸附流速為1BV/h、溫度為20～40℃，出水ρ(COD)平均在155～183mg/L之間，COD去除率在99.1%～99.4%之間，吸附-脫附效果穩(wěn)定；萃取-吸附的COD總?cè)コ蔬_(dá)到99.8%以上，徹底實(shí)現(xiàn)了辛醇廢堿液中的有機(jī)物回收。 |

| The experimental study on treatment of octanol waste lye using extraction - macroporous resin adsorption process was carried out. The results showed that a, the effluent ρ (COD) fell to 6453mg/L or less and the COD’s removal efficiency reached more than 93.8% when the influent ρ (COD) is 104651mg/L, the octanol as octanol waste lye extraction agent, at pH = 3, the volume ratio of octanol to waste lye is 0.5, and under the conditions of extraction stages 2. In addition, the extraction agent octanol can be reused; b, the effect of adsorption-desorption was stable and the total removal efficiency of extraction-adsorption COD reached 99.8% when the effluent water in secondary extraction was used as water, the flow rate of HYA-106 macroporous resin adsorption was 1BV/h, a temperature of 20 ~ 40 ℃, and effluent ρ (COD) average in 155 ~ 183mg/L. The organic recovery from octanol waste lye was fully realized. |
