生物膜法和SBR法相结合处理难降解制药废水的研究

采用生物膜法和SBR法相结合的废水处理工艺处理含抗生素类等难降解的制药废水 ,对生物膜的耐冲击负荷能力、生物膜对进水可生化性的影响、生物膜对好氧SBR活性污泥性能的影响、pH对系统去除效果的影响等工艺条件进行研究 ,并通过与传统SBR处理工艺的对比试验 ,进一步揭示了生物膜法和SBR法相结合的处理工艺强的耐冲击负荷能力。

STUDY ON THE TREATMENT OF PHARMACEUTICAL WASTEWATER BY BIOFILMS-SBR

The technology combined anoxic biofilm reactors with aerobic sequencing batch reactors was used to treat pharmaceutical wastewater which included refractory biodegradation pollutants such as antibiotic.The technique parameters such as the biofilm endurance of shock loading,the effect of biofilm on the biodegrability of influent and the properties of aerobic sequencing batch reactor activated sludge,the effect of pH on removal rate of the system were analysed.Through comparison with single biofilm and SBR without biofilm reactor,the biofilm-SBR system showed higher endurance of shock loading.
