Shanghai techniques and methods in the pharmaceutical industry wastewater treatment equipment author of the article: my country's food which contains a lot of chemicals, so that the rapid development of my country's pharmaceutical industry, pharmaceutical waste water has gradually become one of the major sources of pollution, how to deal with this type of wastewater is today A difficult problem in environmental protection. The following environmental protection water treatment equipment company will introduce several methods of wastewater treatment equipment in the pharmaceutical industry. 1. Coagulation sedimentation method The physicochemical method is the more economical coagulation sedimentation method as the first choice. Generally, after coagulation treatment, not only can the concentration of pollutants be effectively reduced, but the biodegradability of wastewater can also be improved. Coagulants commonly used in industrial wastewater treatment include: polyferric sulfate, ferric chloride, ferrous salts, polyaluminum chloride sulfate, polyaluminum chloride, polyaluminum ferric sulfate, polyacrylamide (PAM), etc. The disadvantages of the flocculation sedimentation process are: a large amount of chemical sludge will be produced; the pH value of the effluent is low, and the salt content is high; the removal rate of ammonia nitrogen is low. 2. Air flotation method Air flotation method usually includes various forms such as inflatable air flotation, dissolved air flotation, chemical air flotation and electrolytic air flotation. In the treatment of wastewater in the pharmaceutical industry, such as gentamicin, oxytetracycline, and methylenetetracycline, chemical air flotation is often used. 3. Adsorption method Adsorption method refers to the use of porous solids to adsorb certain or several pollutants in wastewater to recover or remove pollutants, thereby purifying wastewater. In the treatment of wastewater from the pharmaceutical industry, coal ash or activated carbon is commonly used to pre-treat the wastewater produced in the production of proprietary Chinese medicines, mifepristone, diclofenac, linmycin, paracetamol, and vitamin B6. 4. Blow off method When the concentration of ammonia nitrogen greatly exceeds the allowable concentration of microorganisms, it is difficult to obtain a good treatment effect in the biological treatment process. Catching ammonia to remove nitrogen is often the key to the effectiveness of wastewater treatment. In the treatment of wastewater in the pharmaceutical industry, stripping methods are commonly used to reduce the ammonia nitrogen content, such as the ammonia removal of amiodarone wastewater. The environmental protection water treatment equipment company reminds you: Wastewater treatment equipment is a more commonly used equipment, and many problems will be encountered in the application process.
