Daqing sodium acetate solution equivalent is more than 420000. It mainly releases phosphorus in the anaerobic section, absorbs excessive phosphorus under aerobic conditions, and then removes it through sludge discharge, so as to achieve the effect of biological phosphorus removal. Solution: add nitrification link in the sewage treatment plant, introduce nitrifying bacteria, convert ammonia nitrogen into salt nitrogen, and reduce salt nitrogen into discharge through subsequent denitrification. Nature and use: colorless or white grain crystal, which can be weathered and combustible in the air. The crystal water is lost at 123 ℃. But usually the wet process has the taste of acetic acid. Hydrolysis occurs in water. Daqing sodium acetate solution equivalent above 420000 can be divided into solid and two kinds, solid: colorless or white crystal Clear, without sexual odor. Mainly used in printing and dyeing industry, photography, electroplating, chemical reagents and organic synthesis. In the production of hot water bags, hot water bags, warm feet, warm water bags, warm handbags, and electric water bags.
The crystallization point is 58 ℃, and the density is 1.528 g/cm ³. The BOD5 equivalent of sodium acetate in Daqing sodium acetate solution is 0.52 (mgBOD/mg sodium acetate), so when sodium acetate is added as a carbon source, the calculation formula is as follows: dosage X=(4-CBOD5/Cn) × Cn/0.52.
It is alkaline. Because acetate ion and sodium ion are ionized, acetate ion is a weak ion that can be hydrolyzed to produce hydroxyl ion, while sodium ion cannot be hydrolyzed, so it is alkaline. The ion reaction of sodium acetate solution is: CH3COO -+H2O=CH3COOH+OH -. Note: The solution is a mixture, so there is no chemical formula, but its main effective component is CH3COONa.
”The practice of upgrading sewage treatment plants in various places has also proved that many "inborn deficiencies" have caused the difficulty of nitrogen and phosphorus removal. The so-called mainstream process is a conventional and representative treatment process. For example, A2O and C are mainstream processes. Side flow process is a process name. Popular understanding is a kind of separation. Sodium acetate is mainly used in printing and dyeing industry, photography, electroplating, chemical reagent and organic synthesis. In the anoxic denitrification stage, the nitrate nitrogen (NO3-N) in the sewage is reduced to gaseous nitrogen (N2) under the action of denitrification bacteria.
Anaerobic tank can effectively measure sludge concentration, sludge load, sludge age, and the concentration of organics in sewage, which is conducive to the degradation of organics in the reactor. Therefore, anaerobic tank is also widely used in sewage treatment. This is a municipal sewage treatment process technology, which meets the requirements of further phosphorus removal on the basis of conventional secondary sewage treatment in order to solve the eutrophication of water bodies at the current stage in China. Daqing sodium acetate solution equivalent is more than 420000. In sewage treatment, if more carbon source is added, especially in the treatment of organic pollutants, it will have a certain impact on the follow-up treatment and: high: too many carbon sources will lead to COD. Although COD is an indicator reflecting the content of organic pollutants in water, too high COD will affect the subsequent treatment effect.
