Zhangzhou sodium acetate solution bulk quotation 4. Timely dosing according to water quality changes to ensure treatment effect. In conclusion, the calculation of carbon source dosage for sewage treatment should comprehensively consider the factors in theoretical calculation and practical operation to ensure the sum of dosage to achieve the treatment effect. In the process of microbial degradation of organic matter, the key enzymes and intermediates are different, and the microbial bacteria acting on them are different, that is to say, there are differences in the biological pathways of different carbon sources. 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. Zhangzhou sodium acetate solution bulk quoted products are 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 Zhangzhou 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.
In fact, in addition to the metabolic needs of microorganisms, the C/N ratio is generally adjusted to more than 4. This is because under normal circumstances, denitrifying bacteria need to consume the oxygen carried by the reflux before entering the denitrification reaction, and the carbon source in the water needs to be consumed in the consumption of this part of oxygen. Therefore, the C/N of the AO denitrification process needs to be greater than 4 (generally 4-6) in order to truly denitrification by denitrifying bacteria. 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.
Chemical enhanced biological phosphorus removal sewage treatment process is mainly to remove organic pollutants and phosphorus in various forms in sewage. This sewage treatment process integrates chemical phosphorus removal and biological phosphorus removal, and generates volatile organic acids through anaerobic digestion of activated sludge in biology, which is used as the substrate or nutrient for the growth of phosphorus accumulating bacteria, so that phosphorus accumulating bacteria can selectively proliferate in activated sludge, And recycle it into the organism, so that the biological sewage treatment work is in the phosphorus removal state; At the same time, the sludge is. Zhangzhou sodium acetate solution quotation Why should the sewage treatment plant add carbon source for nitrogen removal. Carbon source is a kind of nutrition that can promote the growth of microorganisms and provide energy for microorganisms in life activities. Denitrification and denitrification of sewage refers to the biochemical reaction and conversion of salt and nitrogen in water under the action of denitrifying bacteria. Denitrifying bacteria need small molecules of easily degradable organic carbon source.
