| 摘 要： | 以北京高碑店污水处理厂二级生化出水为对象，研究了用于地下回灌的活性炭三级处理工艺。活性炭可有效降低DOC，UV－254和COD，部分去除可吸附有机卤化物（AOX）。再经过土壤含水层处理，约90％的可吸附有机溴化物（AOBr）可被去除。Ames试验结果显示活性炭工艺可有效降低二级生化出水中的致突物。GC／MS分析表明，活性炭吸附可降低有机物含量，再经土壤含水层处理，大部分有机物及优先控制的污染物可被去除。

| Abstract: | The secondary effluent from Gaobeidian Sewage Plant was treated with the granular activated carbon(GAC)tertiary process for groundwater recharge.DOC,UV-254 and COD could be effectively decreased,and absorbable organic halogens(AOX)was partially removed by GAC adsorption.GAC adsorption and soil-aquifer treatment(SAT)removed around 90% absorbable organic bromine(AOBr).Ames test results revealed that GAC adsorption could remove mutagens effectively.GC/MS analysis showed that GAC adsorption could reduce the concentration of organic compounds.After SAT,most organic compounds and priority-control compounds could be eliminated. |
