摘　　要：通过试验研究了氧化塘处理采油废水的生化降解规律,求取了生化降解动力学方程。研究结果表明:主要污染物COD生化降解过程近似为一级动力学规律,COD_b降解可表示为COD=COD_b·e^(k_Tt),生化降解速度与温度有关;细菌是有机物降解的主要作用者,蓝藻(蓝细菌)是吸收和吸附石油类的主要贡献者;塘内复氧主要依靠大气与水面的直接扩散溶解过程来实现。This paper presents the kinetic equations of biochemical degradation which occur in the treatment of wastewater from oil recovery in oxidation pond. The following is tile result of the experiments: the kinetic equation of the biochemical degradation process of the main pollutants COD is approximately Y= ax± b, the degradation of CODb can be expressed by the formula CODe = CODb e-kr, the speed of biochemical degradation has something to do with temperature; bacteria play A main role in the degradation of org...
