Sewage treatment is made of sodium acetate, a carbon source liquid
At present, the external carbon sources commonly used in sewage treatment plants to solve low-carbon source sewage treatment are methanol, starch, sodium acetate, etc., of which methanol and sodium acetate are easily degradable substances, which do not contain nutrients (such as nitrogen and phosphorus), and do not leave any intermediate products that are difficult to degrade after decomposition. The starch is a polysaccharide structure, the time required for hydrolysis to small molecule fatty acids is long, and the solubility in water is poor, it is not easy to completely dissolve in water, and it is easy to cause problems such as residues and sludge flocs.
The city's sewage has low-carbon relatively high nitrogen and phosphorus water quality characteristics, due to the low content of methanol organic matter, the use of conventional nitrogen removal process can not meet the demand for carbon sources in the stage of hypoxia denitrification, resulting in denitrification process obstruction, and inhibit the value-added of heterotrophic aerobic bacteria, so it greatly affects the operation effect of sewage treatment plants. As a new material, sodium acetate has been fully developed in more industries, and it makes up for many problems, which is a major element for sewage treatment. Now let's go with Xiaobian to see why sodium acetate can be widely used in sewage treatment plants, and why is it recommended to use PE sodium acetate tanks when storing?
In modern sewage treatment plants, sodium acetate is often used, and its reaction rate when used as a carbon source is much higher than that of methanol and starch. Sodium acetate is convenient and fast in the process of use, and there is no pollution during transportation, which can greatly improve work efficiency. Sodium acetate is an alkaline chemical that can chemically react with acidic sewage, treating acidic sewage, which is better than other alkaline chemicals. In life, it not only plays a role in sewage treatment, but also uses it very widely in life. In order to facilitate the operation of the sewage plant, a PE tank is generally used to store sodium acetate first to dissolve and then treat the sewage, and the storage tank material recommends PE plastic sodium acetate tank
Sewage treatment plants to solve the low-carbon source of sewage treatment commonly used additional carbon sources are methanol, starch, sodium acetate, etc., of which methanol and sodium acetate are easily degradable substances, itself does not contain nutrients (such as nitrogen, phosphorus), decomposition does not leave difficult to degrade intermediate products. Starch is a polysaccharide structure, the time required for hydrolysis to small molecule fatty acids is long, and the solubility in water is poor, and it is not easy to completely dissolve in water.
What role does sodium acetate (sodium acetate) play in sewage treatment
Because sodium acetate is a salt that can be hydrolyzed, hydrolysis is alkaline, so it can be used to treat acidic sewage, and it is better to treat sewage with salt than simply neutralizing acid and alkali, and the cost of sodium acetate as a carbon source for sewage treatment plants is lower than that of methanol, starch, glucose and so on.
The application of sodium acetate as a carbon source in sewage treatment plants includes the following steps: 1) adjust the pH value of industrial sewage in the regulation tank, and then adjust the pH value of industrial sewage in the sedimentation tank for precipitation; 2) The precipitated industrial sewage is transported to the microbial culture tank for microbial oxidation treatment, and sodium acetate is added as the carbon source of microorganisms during the transportation process; 3) The industrial wastewater after the oxidation treatment of microorganisms is treated with a second sedimentation treatment to obtain clear water outflow.

Sodium acetate solution carbon source tank is commonly used in sewage treatment
Sodium acetate (Sodium acetate) is also called sodium acetate, convenient for transportation and storage, the current sewage treatment plant to solve the low-carbon source of sewage treatment commonly used additional carbon sources are methanol, starch, sodium acetate, etc., of which methanol and sodium acetate are easy to degrade substances, itself does not contain nutrients (such as nitrogen, phosphorus), decomposition does not leave any difficult to degrade intermediate products
When sodium acetate is used as a carbon source, its denitrification rate is much higher than that of methanol and starch. The main reason for this is that sodium acetate is a low molecular weight organic acid that is easily utilized by microorganisms. The sugars of polymers such as starch need to be converted into low-molecular organic acids such as acetic acid, formic acid, propionic acid and other low-molecular organic acids that are easily degradable, and then they are used; Although methanol is a fast and easy to biodegradable organic matter, methanol must be converted into low-molecular organic acids such as acetic acid to be used by microorganisms, so the use of sodium acetate as a carbon source is much faster than the use of starch and methanol for denitrification
Sodium acetate itself is not a dangerous good, convenient for transportation and storage, the price is cheaper than methanol, so for some sewage treatment plants that have been built, due to its land use restrictions, when it is necessary to add carbon sources, the use of sodium acetate as an external carbon source is more advantageous than methanol.
