摘要
采用厌氧-好氧一体式折流板生物反应器,在好氧室添加废旧橡胶作为微生物附着生长填料的情况下,进行了该反应器处理马铃薯淀粉废水中COD和NH3-N的去除试验。试验结果表明:在温度为25～35℃,pH值为5.0～8.5时,出水COD浓度低于200mg/L,反应器COD总去除率最高达到98%,出水氨氮浓度在10mg/L左右,氨氮去除率达到74.7%。
The Anaerobic-aerobic Integrative Baffled Bioreactor were used for treating potato starch wastewater, which is a kind of high concentration of organic wastewater. Latex materials were used as carriers filled in aerobic pond to support the growth of microorganisms. The results indicated that the COD concentration in the effluent was less than 200mg/L and the maximum removal efficiency of COD was up to 98% under the following operation conditions： temperature, 25-35℃ and pH 5.0-8.5. The NH3-N concentration in the effluent was around 10mg/L and the removal efficiency of NHrN was up to 74.7%.
