摘要
在低温条件下,采用厌氧折流板反应器(ABR)处理城市污水(中试)。试验结果表明,通过控制水力停留时间(HRT)和水力负荷率(Vr),当进水COD和SS浓度分别为150～350mg/L和90～240mg/L时,去除率分别达到65%～75%和80%～85%。保持第3、4格室污泥浓度在20g/L左右,防止影响厌氧污泥产甲烷活性。
Anaerobic baffled reactor（ABR）was applied to treat municipal wastewater at low temperature（Pilot test）.The results of test showed that the removal can come up to 65%-75% and 80%-85%,respectively, when the influent COD and SS concentration are 150-350 mg/L and 90-240 mg/L by controlling hydraulic retention time（HRT）and hydraulic loading rate（Vr）.Keeping the sludge concentration 20 g/L prevented to affect methanogenic activity of anaerobic sludge in third and fourth compartment.
