Correction and Application Example of Theoretical Calculation Formula for Sodium Acetate Carbon Source Dosage in Wastewater Treatment Plants
In order to ensure that the total nitrogen in the effluent of WWTP with insufficient carbon source meets the discharge standards,it is necessary to add external carbon source.Sodium acetate is the most commonly used carbon source,but relatively accurate calculation methods for sodium acetate dosage are lacking at present.A more accurate formula for calculating sodium acetate dosage was obtained through mathematical derivation,which was successfully applied in engineering practice.The effluent quality reached the standard stably,and the expected goals of saving drug consumption and reducing cost were realized.It can provide reference for the design and later operation of additional carbon source in WWTP.
