摘　　要：考核了生产运行中回流比对A/O工艺处理化工混合废水的除碳和脱氮效果的影响;推导了含二沉池出水SS和进水中含NOX-N的脱氮效率的污泥回流比计算公式;分析了影响脱氮效率的决定因素,为生产运行和管理提供了科学依据。Efficiencies of organic substances and nitrogen removal were investigated in the full scale anoxic/oxic process for treating chemical mixed wastewater treatment. Two formula of returned sludge ratio were provided according to balances of suspended solid in secondary settling tank and denitrification efficiency. The efficiency of key factors in nitrogen removal was analyzed, which would provide a scientific basis for the production and management.
