厌氧反应器内颗粒污泥沉降速率的测定与研究

Measurement and study of settling velocity of granular sludge in anaerobic reactors

采用重量沉降法对上流式厌氧污泥床和厌氧颗粒污泥膨胀床生产装置中颗粒污泥的沉降速度进行了测定,将测定结果与沉降速度模型法计算的结果进行了对比,2种方法之间的误差不超过10%。因此认为重量沉降法与沉降速度模型法可作为生产实践中厌氧颗粒污泥沉降速度的确定方法。

The setting velocities of granular sludge in upflow anaerobic sludge blanket reactor and expanded granular sludge bed were measured using method of electronic sedimentation balance. The result of the measurement was compared with the result gotten from the calculation using settling velocity model; the error between the results from the two methods was not above 10%. So, il is recommended that both of them can be applied as reliable methods to determine the settling velocity of anaerobic granular sludge in production practice.
