Description

technical field

[0001] The invention belongs to the technical field of environmental protection, and specifically relates to a chemical biological flocculation-a method for treating urban sewage with a suspended packing bed. Background technique

[0002] With the continuous increase of the global population, the continuous development of society, and the continuous acceleration of urbanization, the growth rate of urban sewage volume is alarming. And because urban sewage contains a large amount of inorganic nutrients such as nitrogen and phosphorus, resulting in eutrophication of the receiving water. In the current treatment of urban sewage, the activated sludge method is absolutely dominant. The traditional activated sludge method does not have the function of nitrogen and phosphorus removal. Based on the theory of biological aerobic nitrification, anoxic denitrification and anaerobic phosphorus release, aerobic excess phosphorus uptake, a series of activated sludge for bio...
