The Qiqihar sodium acetate was delivered on the same day. Therefore, 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, the emission sources of greenhouse gases were formally classified into five parts: energy activities, industrial production processes, agricultural activities, urban waste and land use change and forestry.
Sodium acetate is a carbon source! COD of sodium acetate delivered on the same day 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!
It mainly includes ion exchange method and medicament softening method. Sodium acetate is delivered on the same day 5. Membrane separation methods are commonly divided into four categories: microfiltration membrane, ultrafiltration membrane, membrane and reverse osmosis membrane. In wastewater treatment, phosphorus releasing bacteria mostly grow on the surface of sludge particles, or attach to fillers or suspended solids together with oxygen and organic matter load. The error of Qiqihar sodium acetate delivered on the same day is large, and the time of dissolution, hydrolysis, ionization, etc. of solid carbon source after entering water should be considered. Under the conditions, carbon source should be added in the form of solution as far as possible, and metering or automatic control should be done well. The concentration of carbon source solution should be high and low. Before dosing, pay attention to pretreatment, filtering and control before dosing pump.
Biological carbon source: biological carbon source refers to the cost performance ratio of some macromolecular sugars, agricultural waste, etc. through the principle of bioengineering. Qiqihar 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 cause COD to exceed the standard.
Qiqihar sodium acetate was delivered on the same day. In practical applications, 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. 2. High ammonia nitrogen: ammonia nitrogen in sewage is usually removed by 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.
