摘　　要：在室内小型模拟反应池内,在静态条件下,在25.1℃、28.8℃和长达84h时间内实验研究了氧化塘处理采油污水时COD的生化降解规律。结果表明,胜利油田桩西联高含盐采油污水的主要污染物COD在氧化塘的好氧生化降解过程可近似为一级反应动力学过程,降解速率常数k与温度(℃)之间的关系可表示为:k(T)=0.04578×1.054T-20h-1;可生化降解CODbd的生化降解动力学关系为:CODbd=CODbd,0exp(-kt)mgL-1。k的温度系数θ=1.054。图4表3参3。The aerobic biochemical degradation of COD of oilfield produced water in oxidation pond is studied in a laboratory miniaturized simulation pond at static condition at 25.1℃ and 28.8℃ up to 84 hrs.
