摘　　要：以黑石子垃圾渗滤液强化预处理-生物接触氧化处理技术为依托,针对其处理效果的局限性,设计了预处理-生物接触氧化反应器,并进行生物接触氧化反应器试验及其有机物降解动力学模型研究,旨在优化运行参数,提高渗滤液处理效能。得出以下结论:生物接触氧化反应器系统处理效能好,出水水质较黑石子垃圾渗滤液处理工艺得到大幅度的改善;对接触氧化反应器垃圾渗滤液有机物降解生化反应过程进行量化研究,得到微生物生长动力学模型:1/θc=0.9187YOA·q-0.0025;根据生物接触氧化内基质消耗过程的物料平衡,得到生物接触氧化反应器处理垃圾渗滤液有机污染物生物降解的动力学模型为q=1.09S/(10230+S),以此指导反应器的优化控制、设计与应用。The biological contact oxidation reactor was designed based on Heishizi landfill lechate treatment and contrapose its limitation.Its ogannic degradation dynamic model reaseach was carried through oxidation process to optimize Biological contact oxidation reactor＇s parameter and increase disposal efficiency. Results showed that： the removal efficency of iological contact oxidation reactor can be improved greatly; its microorganism growth dynamic model can be described as 1/θc=0.9187YOA·q-0.0025;And its ogannic degradation dynamic model can be described as q=1.09S/（10230＋S）. As for this, guidance can be gained to optimize reactor＇s function, design and appliance.
