摘要
应用镜检观察活性污泥性能是目前处理城市污水广泛采用的方法。镜检中指示性生物的种类数量和菌胶团的形态变化能直接反映处理水质的好坏 ,但由于采用活性污泥方法处理污水工艺流程不同 ,则活性污泥中生物相的组成也会有一定的差异。所以要根据情况观察积累 ,调整工艺参数 。
The microscopic observation of activated sludge prope rties is extensively adopted in current sewage treatment works. Variation in the number of indicative living things and in the state of bacteria gel mass can directly reflect the quality of treated water. As the composition of the activated sludge biophase depends on the treatment process, relevant parameters must be adjusted on the basis of observation to achieve desirable water clarification.
