Treatment of Antibiotic Wastewater by Flocculation-A/O Process
絮凝-厌氧-好氧处理抗菌素废水的试验研究

The toxicity experiment in serum bottle showed that antibiotic wastewater has serious inhibitory effect on anaerobic fermentation,pre treatment(flocculation)can reduce this inhibitory effect.A flocculant,regent B which can remove 50% COD of wastewater was obtained.After being pre treated,wastewater was treated by UASB reactor,60% COD was removed,and granular sludge was formed in reactor.Then the wastewater went through two grade aerobic treatment,the COD of effluent can be reduced to below 300mg/L,meeting the wastewater discharge standard of biological pharmacy.
