Now with the increasingly stringent environmental protection policies, many sewage treatment companies are constantly improving their sewage treatment processes. Among many different sewage treatment processes, biochemical treatment processes are particularly concerned by sewage treatment companies. An important link in the biochemical treatment process is bacterial culture, which is related to the success or failure of the biochemical treatment process. The focus of bacterial culture lies in the selection of bacterial nutrient solution. The cultivation of bacteria requires water, nitrogen sources, inorganic salts, carbon sources, growth factors and other substances. Among them, sodium acetate products are used as the carbon source. The carbon source often used in the past is urea, but There are many residues in the urea industry, and it is easy to re-pollute the water and burn the bacteria. In recent years, through continuous exploration, it has been found that sodium acetate has better advantages as a carbon source for bacterial culture. The industrial product of sodium acetate is called sodium acetate trihydrate, which itself contains water molecules and will not burn due to high concentration. Dead bacteria, coupled with the high purity of sodium acetate, only contains a small amount of industrial residues, so it will not cause secondary pollution of water bodies.
