Wastewater issues: The sources of wastewater from the pharmaceutical plant include process wastewater, mechanic and flushing wastewater, initial storm water, and employee domestic wastewater.
Treatment effect: Generally, the impurities in the water are precipitated, because pharmaceutical factory wastewater has antibiotics and other components, and the casual discharge has a very big impression on the water quality, which needs to be treated in stages by each process. Pharmaceutical wastewater is divided into biopharmaceutical wastewater and chemical pharmaceutical wastewater.
Biopharmaceutical wastewater is characterized by high concentrations of organic matter, COD, large fluctuations in BOD values, large differences in BOD/COD values of wastewater, high NH3-N concentrations, deep chromaticity, large concentrations and high ss. Chemical manufacturing pharmaceutical wastewater is characterized by high COD, high salt content and high pH variation wastewater with a single composition is not conducive to microbial growth and contains toxic and non-degradable substances.
Use of polyacrylamide for pharmaceutical plant wastewater: PAM polyacrylamide flocculant, which can quickly and effectively make the suspended particles in pharmaceutical wastewater, the dregs of a decoction precipitation from raw materials, etc., reduces the concentration of pollutants degree and improve the biodegradable properties of the wastewater.
