| Product Introduction: | Sodium acetate is also known as sodium acetate. The sodium acetate solution is a mixture, so it has no chemical formula, but its main active ingredient is CH3COONa. Sodium acetate is a strong electrolyte that is easily soluble in water, so sodium acetate solution is electrically conductive. Sodium acetate products are divided into solid and liquid, among which liquid sodium acetate is mainly used for the treatment of municipal sewage, and the effects of mud age (SRT) and external carbon source (sodium acetate solution) on the effect of system nitrogen and phosphorus removal are studied. The denitrification sludge was acclimatized with sodium acetate as a supplementary carbon source, and then the pH value rise during the denitrification process was controlled within the range of 0.5 by using a buffer solution. The denitrifying bacteria can over-adsorb CH3COONa, so the COD value of the effluent can be maintained at a low level when denitrification is carried out with CH3COONa as an external carbon source. At present, all cities and counties need to add sodium acetate as a carbon source if they want to meet the first-class discharge standard for sewage treatment. |
