The sodium acetate manufacturer in Quanzhou City, Fujian Province is used for, printing and dyeing, and organic composition is used as a mordant. Sodium acetate is a relaxation granule. In sewage treatment, methylchun and sodium acetate are easy to degrade and do not contain nutrients (such as nitrogen and phosphorus). After decomposition, no intermediate products difficult to degrade will be left. However, starch is a polysaccharide structure. It takes a long time to hydrolyze it into small molecule fatty acids. It has poor solubility in water and is not easy to completely dissolve in water, which is easy to cause problems such as many residues and sludge flocs.
In fact, it is a serious problem that the influent carbon source of WWTP is insufficient and the efficiency of nitrogen and phosphorus removal is low.
Water users who are engaged in sewage treatment know that denitrification uses organic carbon source as electron donor to reduce nitrite nitrogen or nitrate nitrogen to. Generally speaking, biological nitrogen removal requires that the influent BOD5/TN>4, but many sewage plants have influent BOD5/TN far below this value, so naturally TN cannot meet the requirements. At this time, additional carbon sources are very important.
Due to the different molecular structures of different carbon sources, the effect of external carbon sources on nitrogen and phosphorus removal from sewage is also different. However, in denitrification, the carbon source that can be quickly biodegraded and will not produce secondary pollution is the choice of electron donor in denitrification.
At present, there are three main types of external carbon sources that are paid more attention to:
Liquid based external carbon sources (methyl, ethyl, crystalline sodium acetate, glucose, etc.), biodegradable polymers, natural cellulose, etc.
Sodium acetate in Quanzhou City, Fujian Province, but sodium acetate itself is not a dangerous product, which is easy to transport and store, and its price is cheaper than that of A Chun. The crystal water is lost at 123 ℃. But usually the wet process has the taste of acetic acid. Hydrolysis occurs in water. It is alkaline. 1. Determine lead, zinc, aluminum, iron, cobalt, antimony, nickel and tin. Complexing agent. Auxiliary agent of yi acylation. The content of sodium acetate in Quanzhou, Fujian Province: ≥ 20%, 25%, 30%. However, high molecular sugars such as starch need to be converted into easily degradable organic substances such as acetic acid, formic acid, and other low molecular organic acids before use; Although methylchun is a fast biodegradable organic substance, it can only be used by microorganisms when it is converted into low molecular organic acids, such as acetic acid.

Quanzhou, Fujian Province Sodium acetate Quanzhou, Fujian Province Sodium acetate itself is not a dangerous product, which is convenient for transportation and storage and cheap. Therefore, for some built sewage treatment plants, due to their land use, when additional carbon sources are needed, it is more advantageous to use sodium acetate as an additional carbon source. The advantage of sodium acetate in addition of carbon source is that denitrifying bacteria supplement carbon source, train denitrifying sludge, and then use buffer solution to control the increase of pH value in denitrification within 0.5.
