摘　　要：采用在悬浮相污泥中投入纤维球填料形成单一复合生物反应器来处理焦化废水,研究了各个运行参数对复合生物反应器处理效果的影响,确定出最佳的运行参数,并研究了在最佳运行条件下复合生物反应器对焦化废水中的COD和NH3N的去除情况。试验结果表明,采用单一复合生物反应器是一种很好的焦化废水处理方法,它能有效地降解焦化废水中的COD和NH3N等难降解物质,当进水COD和NH3N分别小于670、260mg/L时,COD和NH3N的去除率分别可高达94.8%和91.4%。A single hybrid biological reactor was used in treating coke plant wastewater by throwing fibre-ball filler into suspended phase activated sludge, the effect of many operation control parameters on disposal effect in a single hybrid biological reactor, the optimum control parameters were defined and it was researched that a hybrid biological reactor treated COD and NH_3-N in coke plant wastewater. The disposal result showed that using hybrid biological reactor was a better process of disposing coke plant wastewater, which can degrade efficiently COD and NH_3-N and many refractory organic compounds in coke plant wastewater. The removal rate of COD and NH_3-N was up to 94.8% and 91.4% respectively, when the influent COD and NH_3-N was less than 670 mg/L and 260 mg/L individually.
