Generation of waste water
2021-11-12
Biopharmaceutical wastewater treatment is currently a very important and very difficult to deal with wastewater in the wastewater treatment industry. Biopharmaceutical refers to the use of organisms or biological processes to produce drugs, mainly including antibiotics or antibiotics generated by the method of fermentation of bacteria, which will produce corresponding pharmaceutical wastewater in its production and processing wastewater. Today, Zhongke Boyun will show you what are the main characteristics of biopharmaceutical wastewater.
1. Generation of wastewater
Fermentation of biological pharmaceuticals is through the life activities of microorganisms, food and other organic raw materials for fermentation, filtration, refining into pharmaceutical products, such drugs include antibiotics, vitamins, amino acids, accounting, organic acids, coenzymes, enzyme inhibitors, hormones, immune regulatory substances and other physiological activity substances.
(1) Drainage from main production processes: such drainage includes filtrate, waste mother liquor, solvent recovery residue, etc. The main characteristics of this type of wastewater are high pollution concentration, large fluctuations in pH value, and many residues of pharmaceutical ingredients. Although the amount of water is not necessarily too large, it is difficult to treat due to its high pollutant content and high COD value.
(2) Auxiliary production process drainage: including cold water, power equipment cooling water, water ring vacuum equipment drainage, distillation equipment condensate, etc. The concentration of such drainage pollutants is low, but its water volume is large and seasonal, and the difference between enterprises is large.
(3) Flushing water: mainly includes container equipment flushing water, filtering equipment flushing water, ion exchange equipment flushing water, workshop floor flushing water, etc. The nature of this kind of drainage changes greatly. For example, the concentration of suspended solids in filtering equipment flushing water is very good. If it is not properly controlled, it will become an important source of pollution,
