The pure mixing of Guangyuan sodium acetate should not be allowed. Excessive hydraulic mixing intensity will cause hydraulic cutting and sludge collision, which will cause physical disintegration of sludge flocs, and make it difficult for carbon sources to be adsorbed on the sludge surface, affecting the denitrification efficiency. The input of carbon source shall be conducted in an extensive manner, and the carbon source supplement shall be conducted in liquid form as far as possible. If the conditions are not good, according to the technical personnel, the solid carbon source can be weighed and sprinkled into the front end of the denitrification tank.
Sodium acetate is a carbon source! Pure COD of sodium acetate is 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!
The organic matter (carbon source) in the sewage is fermented into volatile fatty acids (VFAs) under anaerobic conditions, which can be converted into polybutyric acid and stored in cells in the form of polybutyric acid and other organic particles, so that it is also in vitro in the degradation of polysalts. The raw material supply of volatile fatty acids (VFAs) in biological phosphorus removal is provided by the carbon source, no matter whether the carbon source is brought from raw water or supplemented additionally. In biochemical nitrogen removal, Guangyuan Sodium Acetate will add carbon sources to promote the denitrification reaction and nitrogen removal efficiency when the carbon nitrogen ratio of biochemical pool is not suitable. 5. The life cycle analysis/assessment of the life cycle method is the follow-up assessment of the product "from cradle to grave" [13].
Biological carbon source: biological carbon source refers to the cost performance ratio of some macromolecular sugars, agricultural waste, etc. through the principle of bioengineering. Guangyuan sodium acetate, however, sometimes the carbon source sold on the market is not fully fermented. Although 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 COD to exceed the standard.
Among the practical applications of Guangyuan Sodium Acetate Pure, Qingdao beer wastewater is famous for its use 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. It simulates the carbon cycle of forest and soil ecology by investigating conditions, including greenhouse, precipitation, solar radiation, soil structure and other conditions 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.
