Strategy analysis of carbon source addition in a municipal sewage treatment plant in Northeast China
The insufficient denitrification and nitrogen removal capacity of biological treatment systems caused by low C/N influent conditions has become a major challenge for the operation of sewage treatment plants in China.Current carbon source dosing strategy using bibliometrics was summarized.Taking a municipal sewage treatment plant in Northeast China as an example,combined with the practical application of various carbon sources,the advantages and disadvantages of several mainstream external carbon sources commonly used were introduced.The reasons for the difference between the theoretical value of methanol,sodium acetate,glucose and Micco carbon dosage calculated by the four carbon source dosage formulas were analyzed to provide technical guidance for urban sewage treatment plants to achieve economic,efficient and low-carbon operation of carbon source dosage strategy.
