摘要
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,用复合生物反应器处理预处理后的焦化废水,研究水力停留时间、pH值、负荷等参数对其处理效果的影响,从而确定最佳运行参数,并在此基础上研究在最佳运行条件下复合生物反应器对焦化废水中COD和NH4+—N的去除效果.结果表明,单一复合生物反应器能有效降解焦化废水中的COD及NH4+—N等难降解物质.当进水COD和NH4+—N分别小于670 mg/L和260 mg/L时,COD和NH4+—N的去除率可分别达到94.8%和91.4%.
Two phase hybrid bio-reactor was used in treating coke-plant wastewater by means of submerging fiber-ball filler in suspended growth activated sludge. The optimum operation parameters for the highest performance were determined in the research. It is found that hybrid biological reactor works well for the coke-plant wastewater treatment in terms of COD, NH^＋4-N and other refractory organic compounds removal efficiency. The removal efficiency of COD and NH^＋4-N was up to 94.8%, 91.4% for 670 mg/L COD, 260 mg/L NH^＋4-N, respectively.
