摘要
采用连续流生化反应装置,对拟建的西安市第四污水处理厂的生化反应动力学参数进行了测定。结果表明:污泥产率系数为0.4573kgVSS/kgBOD5,衰减系数为0.0125d-1,去除单位质量BOD5的需氧量为0.6266kgO2/kgBOD5,单位质量MLVSS的内源呼吸需氧量为0.0924kgO2/(kgVSS·d)。试验结果对污水厂的设计具有重要的参考价值。
Continuous biochemical reactor was used for measuring the kinetic parameters for biochemical reactor in the proposed No. 4 Wastewater Treatment Plant. The result shows that sludge yield coefficient is 0.457 3 kgVSS/kg BOD5 , and decay coefficient is 0. 012 5 d^-1 , the oxygen demand for removing unit mass of BOD5 is 0. 626 6kgO2/kgBOD5 and the oxygen demand for endogenous respiration of MLVSS is 0. 092 4 kgO2/（ kgVSS · d ）. The result is of important reference for design of wastewater treatment plant.
