Zhaoqing sodium acetate manufacturer 1. Activated sludge and domestication stage The primary stage and one of the important links of the sewage plant is activated sludge microorganism and domestication. At this time, microorganisms need a large number of carbon sources to maintain a rapid growth and reproduction, while the sewage treatment carbon source itself is far from enough, This requires the growth and reproduction speed of microorganisms with external carbon source.
Sodium acetate is a carbon source! COD of sodium acetate manufacturer 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!
Anaerobic tanks are commonly used in urban domestic sewage industry and play a key role in nitrogen and phosphorus removal. Zhaoqing sodium acetate manufacturers use microbial phosphorus releasing bacteria, which are a kind of microorganisms that play an important role in wastewater treatment. They can effectively convert organic salts in sewage into inorganic salts and release phosphorus for use by other bacteria. Therefore, the Zhaoqing sodium acetate manufacturer formally classified the emission sources of greenhouse gases into five parts: energy activities, industrial production processes, agricultural activities, urban waste, and land use change and forestry in the "Capacity Building for Initial Information Notification" project launched by the Office of the Climate Change Response Coordination Group of the Planning Commission in October 2001.
Biological carbon source: biological carbon source refers to the cost performance ratio of some macromolecular sugars, agricultural waste, etc. through the principle of bioengineering. Zhaoqing sodium acetate, however, sometimes the carbon source sold in 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 the COD to exceed the standard.
In the practical application of Zhaoqing sodium acetate manufacturer, Qingdao brewery 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. In the application of sewage treatment, it is easy to be absorbed and utilized by microorganisms, and has the characteristics of organic sludge production and sludge activity. It is particularly important to consider how to reasonably use the data and avoid double counting and missing counting in the estimation of sectoral emissions. In addition to providing single point carbon source emission estimation, IPCC also provides the problem of determining key sources through the use of decision trees, how to reasonably use data and avoid double counting.
