Shaoyang Trihydrate Sodium Acetate, Sodium Acetate
Shaoyang Sanshui Sodium Acetate, 2. The nutrient imbalance of influent water will bring a large cost to the sewage plants with unbalanced nutrient. Many sewage plants will stop adding carbon sources after the growth of microorganisms. However, when microorganisms do not have enough carbon sources to maintain their own growth, they will age and disintegrate again. Long term carbon source is required to maintain process operation.
Sodium acetate is a carbon source! Sodium acetate trihydrate and COD are chemical oxygen demand. Sodium acetate: when the COD equivalent is about 200000 (the effective amount of sodium acetate is 25%), and the content continues to rise, crystallization will occur.
Because the molecular chain of glucose is longer than that of sodium acetate, more glucose is used for the early commissioning of activated sludge in the sewage plant, and of course, some glucose is also used for denitrification. COD equivalent is relatively high, but BOD value is relatively low. A by-product salt similar to colorless crystal, such as sodium sulfate. In this way, the COD of industrial glucose will be greatly reduced. So after you buy glucose, you can taste the salt. If it is salty, it is added with a lot of salt. Then measure whether the COD equivalent is!
Carbon source emission control has become a topic of concern, and carbon source emission is also the goal that mankind needs to work together in the future. The carbon source used for wastewater treatment is generally considered to contain carbon elements and is easily used by microorganisms to promote the growth of microorganisms. Trihydrate sodium acetate anaerobic tank is a structure without aeration and with high pollutant concentration, which is suitable for anaerobic microorganism activity to treat pollutants in water because dissolved oxygen is consumed by decomposition and makes water almost free of dissolved oxygen. Shaoyang Trihydrate Sodium Acetate, 2. High ammonia nitrogen: ammonia nitrogen in sewage is usually removed through nitrification/denitrification. When there are too many carbon sources, it is easy to consume oxygen, which will affect nitrification and ammonia nitrogen removal. 3. High total phosphorus: under the condition of aerobic DO, calcification will be used for phosphorus precipitation and removal.
Biological carbon source: biological carbon source refers to the cost performance ratio of some macromolecular sugars, agricultural waste, etc. through the principle of bioengineering. Shaoyang Trihydrate Sodium Acetate, however, sometimes the carbon source sold in the market is not fully fermented. Although the COD can meet the requirements, there are also long-chain organics, which are not easy to be used by denitrifying bacteria, and may also cause the COD to exceed the standard.
In practical application, Shaoyang Trihydrate Sodium Acetate is famous for its use of Qingdao brewery wastewater as a carbon source for sewage treatment. Turning brewery wastewater into treasure, as the carbon source of sewage treatment plant, not only solves the high cost of brewery wastewater treatment, but also solves the problem of carbon source shortage of denitrification in sewage treatment plant. In biochemical nitrogen removal, when the carbon nitrogen ratio of the biochemical pool is not suitable, carbon sources will be added to promote the denitrification reaction of nitrogen removal and nitrogen removal efficiency. 5. The life cycle analysis/assessment of the life cycle method is the follow-up assessment of the product "from cradle to grave" [13].
