STUDY ON THE TREATMENT OF PHARMACEUTICAL WASTEWATER BY BIOFILMS-SBR
生物膜法和SBR法相结合处理难降解制药废水的研究

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.
