Pharmaceutical companies produce a

Pharmaceutical companies produce a wide variety of drugs, the production process is very complex, each drug production process is very different.The pharmaceutical industry produces many organic wastewater pollutants, complex chemical composition, synthetic substances and difficult to degrade.The biodegradability of substances in wastewater is not high.Fermentation wastewater and chemical synthetic wastewater are the main discharge substances that need to be controlled.The high concentration of non-degradable wastewater produced in the production of fermentation drugs mainly contains difficult-to-degradable substances such as antibiotic residues and fermentation residues.Antibiotic extraction also has many organic solvents and inorganic salts.Because of the complex composition of such wastewater, the proportion of carbon and nitrogen is unreasonable, there are a large number of degradation, sulfate and other inhibitors, making biodegradation difficult.Compounds are the main pollutants in pharmaceutical wastewater, which contain drug property, salt and other substances.This kind of pharmaceutical wastewater has strong bio-chemical inhibition toxicity.Pharmaceutical wastewater is often treated by bio-chemical methods, but the efficiency of pollutant treatment is not high, it is difficult to meet the standards of industrial wastewater discharge.
