固定化生物活性炭处理含油废水的试验研究

Study on treatment of oil wastewater with immobilized biological activated carbon

提出一种含油废水处理的新技术,采用人工固定化生物活性炭处理含油废水,其对油的去除效率在80%～95%之间,COD平均去除率达到53%,出水中油质量浓度小于5mg/L.试验结果表明该工艺对污染物的去除效果明显高于颗粒活性炭和传统的二级气浮工艺.

On the basis of the tests, the new method of immobilized biological activated carbon (IBAC) was found to be an efficient one to treat oil wastewater. The oil removal ratio is about 80%～95%, and average COD removal rate can reach 53%, while the effluent oil concentration could gradually be less than 5 mg/L. Concludes from test results that this method will be obviously more efficiency than granular activated carbon and second stage flotation process.
