强化填料SBR工艺处理高浓度制药废水的研究

The study on the treatment of high concentration pharmacy wastewater by SBR added with bio-media

采用常规SBR工艺和强化填料SBR工艺对高浓度制药废水进行了对比处理试验,在强化填料SBR工艺中采用活性炭和页岩陶粒两种填料进行对比处理试验。结果表明:强化填料SBR工艺与常规SBR工艺相比,COD去除率可提高近20%,缩短反应时间10 h。宜采用非限制曝气的进水,最佳运行工艺为一周期28 h,非限制曝气进水1 h,反应25 h,沉淀、排水和闲置2 h。对于不同填料来说,活性炭优于页岩陶粒。

High concentration pharmaceutical wastewater was treated by conventional SBR process and SBR added with bio-media process （SBRA） respectively to compare the treatment effect of the techniques In the SBRA process, activated carbon or shale gravel were added. The result showed： compared with convemional SBR process, the SBRA process can increase COD removal efficiency about 20% and reduce reaction time about 10 hr; the unlimited aeration inflow pattern was more feasible; the best operation process of the SBRA consisted of 1 h unlimited aeration inflow, 25 h reaction, 2 h deposition, drain and layiing aside. Compared with gravel, activated carbon is better.
