【摘要】 血清瓶毒性实验表明，抗菌素废水对厌氧消化具有强烈的抑制作用，废水经过絮凝处理，可以降低废水的毒性．筛选到一种混凝剂（试剂Ｂ），可以去除废水ＣＯＤ５０％．预处理后的废水经过厌氧污泥床（ＵＡＳＢ）的处理，可以去除６０％的ＣＯＤ，处理系统内形成了颗粒污泥．厌氧处理后的出水，再通过两级好氧处理，出水ＣＯＤ可降至３００ｍｇ／Ｌ以下，达到生物制药废水行业排放标准．更多还原

【Abstract】 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.更多还原
