Description

Carbon source adding system

Technical Field

The utility model relates to a carbon source adding system, and belongs to the field of sewage treatment.

Background

In three stages of biological denitrification, namely ammoniation reaction, nitrification reaction and denitrification reaction, ammonia nitrogen in the wastewater must be nitrified or converted into nitrite and nitrate firstly, and then in the denitrification process, the nitrate is reduced into nitrogen denitrifying bacteria as an oxygen supply body for oxidizing simple carbon compounds in the cell respiration process. Can be divided into autotrophic denitrifying bacteria and heterotrophic denitrifying bacteria, wherein most denitrifying bacteria are heterotrophic denitrifying bacteria and require the utilization of organic carbon sources for denitrification. Thus, denitrification processes aimed at nitrate removal must have a readily biodegradable carbon source present.

When the supply of carbon source is insufficient during denitrification, the denitrification speed is reduced, because denitrifying bacteria use their own protoplasm for endogenous denitrification when the supply of organic carbon is insufficient, and finally the cytoplasm of the bacteria is reduced. Therefore, when the water is insufficient in dissolved organic matters and the denitrification requirement is high, the carbon source required by the denitrification process needs to be provided by supplementing chemical substances.

The denitrification rate can be improved in a carbon source supplementing mode by adding an external carbon source into a water inlet of the anaerobic tank or the anoxic tank, but if the external carbon source is excessive or the carbon source is not properly selected, the system operation cost is increased, and the COD of the sewage treatment plant is overproof. And the COD of the effluent cannot exceed the standard by using the carbon source.
