Huanggang crystal sodium acetate carbon source supplier
The carbon source supplier of Huanggang crystal sodium acetate shall try to avoid the parallel area of reflux point. Therefore, the composite carbon source can be added 3-5 m downstream of the internal reflux point (it can be reduced to 2-3 m when the denitrification area is small). At the same time, attention should be paid to avoiding hydraulic dead angle. What is the impact of carbon source addition on nitrogen removal effect? Theoretically, C/N in denitrification tank is 2.86, which can achieve nitrogen removal effect.
Sodium acetate is a carbon source! COD of crystalline sodium acetate carbon source supplier 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!
Most carbon sources are added into the anaerobic tank; Anaerobic tank is set for denitrification in sewage treatment equipment. YDT type three-dimensional elastic filler is set in the tank as the carrier of denitrification. Nitrate ammonia and acid oxygen in the nitrifying liquid are reduced to under the action of denitrification to achieve the purpose of denitrification. The effective retention time of the anaerobic tank is 2.5~3.5h. Anaerobic tank is a common process in sewage treatment equipment, It is used to remove organic pollution in wastewater. Why does Huanggang crystal sodium acetate carbon source supplier add carbon source for nitrogen removal in sewage treatment plant. Carbon source is a kind of nutrition that can promote the growth of microorganisms and provide energy for microorganisms in life activities. Denitrification and denitrification of sewage refers to the biochemical reaction and conversion of salt and nitrogen in water under the action of denitrifying bacteria. Denitrifying bacteria need small molecules of easily degradable organic carbon source.
Biological carbon source: biological carbon source refers to the cost performance ratio of some macromolecular sugars, agricultural waste, etc. through the principle of bioengineering. Huanggang crystal 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 COD to exceed the standard.
In practical applications, Huanggang crystal sodium acetate carbon source supplier is famous for its use 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. Add a retention tank with enough residence time in the conventional process. Then the supernatant and the lower concentrated solution are treated separately, and then they are combined to enter the next operation unit, which is the conventional flow measurement process. Because the TN detection time in the laboratory is too long to meet the requirements in time, online monitoring can be used to transmit TN, COD, NH3-N and other data to the control. After calculating the flow of the automatic carbon source dosing pump or regulating valve opening, the automatic carbon source dosing control can be achieved.
