It mainly plays the role of adjusting the PH value of sewage. It can be hydrolyzed in water to form OH-negative ions, which can neutralize the acidicions in water, such as H+, NH4+ and so on. Hydrolysis reaction formula: CH3COO- + H2O = reversible = CH3COOH + OH-;

As an additional carbon source, the buffer solution was utilized to control the pH rise during denitrification to within 0.5. Since denitrifying bacteria can 

absorb CH3COONa in excess, the COD value of effluent can be maintained at a low level even when denitrification is carried out with CH3COONa as an 

additional carbon source. Sodium acetate has replaced the previous carbon source, and the activity of the sludge has been strengthened;

.

Stabilization of water quality has an important role in the nitrite and phosphorus effluent, as it can be used for the coordination effect, 

which can enhance the strength of corrosion inhibition. If the test in different water sources, you can use a small amount of industrial grade 

sodium acetate to find the appropriate amount of injection, usually the production process will be in the solid and water to the degree of 1 to 5 for

the degree of pairing, first to complete the process of dissolution and then go to add water for dilution.
