【摘要】 在多级折流板反应器生物处理装置中,采用活性炭为载体人工固定化生物处理合成染料废水,出水水质稳定,出水中的烷烃肽链变短;其对CODCr和BOD5的去除率可达96.46%、99.77%;对SO42-和钙镁总量的去除效率超过80.37%、78.66%;折流板反应器的容积负荷率Nv可达2.8 kg COD/(d.m3)。活性炭经生物固定化后,不仅不会影响它的处理效果,还会延长活性炭的使用寿命;当冲击性有机负荷发生时,固定化生物活性炭能够承受并能很快恢复。更多还原

【Abstract】 Synthetic dying wastewater was treated by immobilized biological activated carbon in multistage baffled bioreactor.The water quality of effluent was stable and peptide bond of alkenes was shorted.The COD_Cr removal ratio and BOD₅ removal ratio were 96.46% and 99.77%.The removal ratio of total sulfate radical and magnesium ion exceeded 80.37% and 78.66%.Volumetric loading rate of baffled reactor reached 2.8 kg COD/（d·m³）.The treatment effect wasn’t impacted after the biological immobilized of activated carbon,further more the service life of activated carbon was prolonged greatly.Immobilized biological activated carbon could afford shock loading and recover soon.更多还原
