Abstract
The application relates to a carbon source medicament for sewage treatment, a preparation method and application thereof, which are suitable for treating oily sewage rich in 10-25% of grease. The microbial agent can utilize grease decomposing bacteria to decompose grease so as to supplement glycerol carbon source, improve the life cycle of microorganisms in the carbon source agent for sewage treatment, improve the lasting efficacy of the carbon source agent for sewage treatment, and prolong the purifying capacity of the carbon source agent for sewage treatment on sewage.

9. The use of a carbon source chemical for sewage treatment according to any one of claims 1 to 7, wherein the carbon source chemical for sewage treatment is applied to oil sewage treatment.
