Aerobic tank sludge aging, long sludge age Aerobic tank sludge load, short sludge age, large return flow, short residence time aerobic tank sludge load is low, high dissolved oxygen for a long time, resulting in self-oxidation of sludge (low removal, high dissolved oxygen), more fine sludge, less active sludge insufficient dissolved oxygen, insufficient nutrients or unbalanced proportion of pipe nutrients (N, The COD removal rate of the anaerobic pool is low, the anaerobic hydrolysis effect is poor, the COD concentration of effluent is too high, the raw water contains toxic substances, and the accumulation value of inorganic salts of sludge poisoning exceeds the specified range. The impact load of the aerobic pool is large or the sludge swelling phenomenon occurs in the aerobic pool.
