【 摘 要 】

The quality assessment of activated sludge of biological treatment facilities of pulp and paper mill depending on the type of load is given. Considered three cases of the load on the activated sludge and given their characteristics in the sedimentary and hydrological indicators under conditions of variable load. Depending on the type of load, there is a satisfactory operation of activated sludge, or its swelling caused by the bacteria Zooglea ramigera or filamentous forms of microorganisms.
