摘　　要：针对可生化性极差的制药园区难降解尾水,分别采用单独活性污泥吸附、单独O3氧化及活性污泥吸附+O3联合氧化3种方法进行预处理,并对试验参数进行了优化。结果表明,单独活性污泥吸附法对有机物具有一定去除能力,但不能有效提高废水的可生化性;单独O3氧化法和活性污泥吸附+O3氧化法对有机物去除效果明显,废水可生化性得到显著提高。采用联合法进行预处理,其CODCr去除率可达37.90%,废水的BOD5CODCr从0.020提高到0.141,且其处理成本更为经济。Considering the poor biodegradability of the refractory pharmaceutical park tail water, activated sludge adsorption, O3 oxidation and adsorption of activated sludge coupled with O3 were separately used to pre-treat pharmaceutical tail water, and the test parameters were optimized. The results showed that separate activated sludge adsorption method had a certain ability to remove organic matter, but it could not effectively improve the biodegradability of the wastewater; both the CODcr removal efficiency and the biodegradability of wastewater were greatly improved by O3 oxidation and adsorption of activated sludge coupled with O3. It was verified that activated sludge coupled with O3 process was an effective pretreatment technology, the CODcr removal efficiency could reach 37.90%, and the biodegradability was greatly improved, with BODs/CODcr increasing from 0.020 to 0. 141, and its processing cost is more economical.
