Guizhou's industrial denitrification speed is fast When selecting and using high COD carbon sources, it is necessary to combine specific wastewater characteristics, treatment processes and target requirements, and carry out accurate dosing strategies and requirements. Carbon source is used by microorganisms to synthesize various metabolites through a series of chemical changes in cells. In the economic development of biological phosphorus removal, the main rivers and lakes in China are seriously eutrophic due to phosphorus pollution. In order to control phosphorus pollution, strict regulations have been formulated for phosphorus discharge. 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. Guizhou industrial denitrification products with fast speed 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 industrial sodium acetate in Guizhou 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. Industrial ion reaction: CH3COO -+H2O=CH3COOH+OH -. Note: The solution is a mixture, so there is no chemical formula, but its main effective component is CH3COONa.
After mixing, continue to fully mix with denitrification sludge under the action of stage aeration and submersible mixer. Only when the carbon source, sewage and sludge are fully mixed can the denitrification and pollution be sufficient and the denitrification can be carried out for enough time to achieve the treatment effect. The dosing point can be set on the inlet pipe or at the inlet port of the denitrification tank. It should be noted that short flow should be avoided as far as possible and the denitrification tank should be fully stirred. 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.
4. The temperature and pH deviate from the appropriate range: the addition of high COD carbon source will affect the temperature and pH value in the sewage treatment plant, thus affecting the activity and degradation effect of microorganisms. 2. Increase or decrease the amount of carbon source according to the actual situation to avoid or insufficient. 3. Considering the impact of carbon source type and treatment process on the dosage, different carbon source dosage may have different effects on the treatment effect. Guizhou's industrial denitrification rate is fast. It simulates the carbon cycle of forest and soil ecology by investigating conditions, including greenhouse, precipitation, solar radiation and soil structure, as input variables, so as to calculate the carbon cycle between forest soil atmosphere and greenhouse gas flux. According to the definition of life cycle assessment, theoretically every activity will produce CO2 gas.
