Carbon source composition for biological denitrification and treatment of wastewater using the same

摘要

The present invention relates to a carbon source composition for biological denitrification comprising a main component consisting of fusel oil and waste alcohol, and a method for treating wastewater using the same. The method for treating wastewater according to the present invention comprises a pre-denitrification oxidation process for denitrifying oxidized nitrogen using organic matter in the influent wastewater, and a posterior nitrification process for further denitrification by supplying an external carbon source, The waste water is denitrified by using a carbon source composition composed of oil and waste alcohol as an external carbon source.;The present invention uses a composition of Hugel oil and waste alcohol instead of methanol as an external carbon source, thereby reducing the cost and improving the nitrogen removal efficiency. In addition, it can be said that industrial use is significant because it recycles the waste resources that are incinerated.
