Shaanxi Xianyang Sodium Acetate Industrial Electroplating Sewage Treatment Plant has insufficient carbon source of influent water and low efficiency of nitrogen and phosphorus removal, which is actually a very serious problem.
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, etc.), biodegradable polymers, natural cellulose, etc.
Shaanxi Xianyang sodium acetate industrial electroplating sewage treatment is also called sodium acetate, which is a sodium salt derived from acetic acid. This compound has many industrial and daily uses. In the food industry, it is used as a preservative and pickling agent. Salt can be harmful to growth because it helps food maintain a specific pH value. In pickling, this chemical should be widely used, not only as a buffer for food and microorganisms, but also for food taste. Use of sodium acetate industrial electroplating sewage treatment in Xianyang, Shaanxi: quantitative and effective dosing shall be carried out according to the site conditions. The present appearance has replaced the previous carbon source, and the activity of water quality sludge after use has been enhanced. Sodium acetate products are divided into solid and two kinds, solid C2H3NaO2 content ≥ 58-60%, appearance: colorless or white crystal.
