5. Summary
1. Specific rates of decay of organic part of the activated sludge processed by a complex the heterotrophic
aerobic microorganisms including denitrifiers are received. Depending on various concentration of ashless part of
activated sludge, it makes 3.5-1.4 mg/g hour.
2. It is established that parallel to processes of a deep aerobic mineralization processes of a nitri-denitrification
proceed. The average specific removal rate of total nitrogen was 0.15 mg/g hour. 8-11 mg of organic part
of activated sludge are spent for removal of 1 mg of nitrogen.
3. The effect of destruction of ashless part of a deposit in a construction of a deep aerobic mineralization of
sludge makes 65%.
4. Average value of an ash-content of sludge in the clarified water makes 35% that considerably exceeds a sludge
ash-content in an aerobic mineralizer. Due to flotation processing sludge water finely dispersed sludge with high ash
content is removed.
