Abstract:

It is presented that experiments are needed in order to get the value of YH for each kind of wastewater and treatment process， when ASM1 is used to simulate activated sludge system. Batch activated sludge method and batch respirometric method are introduced. Acetic sodium and real wastewater as substrate respectively，the value of YH for integrated dyeing wastewater treatment plant is measured with the second method. The value is 0.65，and lower than that for domestic wastewater，0.67，which was recommended in ASM1.

Key words: heterotrophic yield coefficient, batch activated sludge method, batch respirometric method

摘要：

指出应用ASM1模拟活性污泥系统时，对于特定的废水及其处理工艺,需要实测异养菌产率系数YH。介绍了YH的两种测试方法：间歇活性污泥法和间歇呼吸计量法。分别以醋酸钠和实际废水为底物，应用间歇呼吸计量法,测定印染综合废水处理厂的异养菌产率系数，最终结果为0.65，低于ASM1模型中城市污水异养菌产率系数的推荐值0.67。
