Bengbu sodium acetate solution carbon source supplier 2. For sewage plants with unbalanced influent nutrition, adding carbon sources will bring large costs. Many sewage plants will stop adding carbon sources after microorganisms grow up, but 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! COD of the carbon source supplier of sodium acetate solution is the 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!
For Yuanjie purified water, you can know that the addition amount of five different carbon sources is calculated as follows: 1. Glucose as the added C source (molecular weight of C6H12O6 is 180g/mol) X=1.066g, 1g glucose can be converted into 1.066gCOD2, and as the added C source (molecular weight of CH3OH is 32.04g/mol, density: 0.7918g/L) X=1.1877g, 1ml can be converted. The carbon source supplier of Bengbu sodium acetate solution should not add too much carbon source in denitrification, or it will affect the microbial species advantage in the denitrification tank. Too much BOD will cause too much anaerobic under anoxic conditions. There will also be more aerobic, consuming BOD and dissolved oxygen. Therefore, the competitive relationship between aerobic, anaerobic and denitrifying bacteria will affect the effect of denitrification treatment.
Biological carbon source: biological carbon source refers to the cost performance ratio of some macromolecular sugars, agricultural waste, etc. through the principle of bioengineering. Bengbu sodium acetate solution, 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 cause COD to exceed the standard.
The carbon source supplier of Bengbu sodium acetate solution is famous for its application of Qingdao beer 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. However, since the IPCC research is generated in a developed background, there is not enough estimation of the emissions involved in the development of fossil fuels and industrial development. Take our country as an example, in energy activities, in addition to fossil, our rural areas still use biomass as fuel to a large extent.
