摘要
本文对杨和麦卡蒂（１９６８年）提出的厌氧滤池动力学关系式进行了验证和修正。结果表明，该关系式用来预测厌氧滤池对有机物的去除率在一定条件下具有相当准确性。关系式中参数ｅ主要由温度、污泥浓度、有机负荷等运行条件确定。以溶解性ＣＯＤ代替ＢＯＤ计算有机物去除率Ｅ、以填料区有效容积代替空池容积计算水力停留时间ＨＲＴ更为合理。
The authors verified and revised the kinetic model of the anaerobic filter proposed by Yong & Mccarty (1968). Under certain conditions the model had better accuracy for expecting organic removal rate. The calculated CODcr removal rates were 86. 0% and 72. 4% in the first phase and second phase. the measured results were 86. 6% and 71. 6% respectively. Two groups of data are very close. Coefficient e in the model is experimentally determined with temperature, sludge concentration and organic loading. It is more reasonable to calculate organic removal rate E with COD instead of BOD and to calculate hydraulic retention time HRT with effective volume of filler zone instead of void filter volume.
