Cationic polyacrylamide can be used for pharmaceutical wastewater treatment, and its effect is generally the impurities in the precipitation water, because the pharmaceutical wastewater contains antibiotics and other components, random discharge has a great impact on water quality, and it needs to be treated in stages.
The wastewater of pharmaceutical factory comes from pharmaceutical factory, including process wastewater, mechanical maintenance, flushing wastewater, initial rainwater, and domestic sewage of employees.
Cation polyacrylamide
Pharmaceutical wastewater is divided into biological pharmaceutical wastewater and chemical pharmaceutical wastewater. Biopharmaceutical wastewater is characterized by high concentration of organic matter, large fluctuation of COD and BOD values, large difference of BOD/COD values, high NH3-N concentration, deep chroma, high concentration and high ss. Chemical pharmaceutical wastewater has the characteristics of high COD, high salt content and large PH value change. The single component of the lung water is not conducive to the growth of microorganisms and contains toxic and non-degradable substances.
The industrial wastewater of pharmaceutical factories mainly includes four categories: antibiotic production wastewater, synthetic medicine production wastewater, proprietary Chinese medicine production wastewater, washing water and washing wastewater in the production process of various preparations. Its wastewater has the characteristics of complex composition, high organic content, high toxicity, deep color and high salt content, especially the industrial wastewater with poor biochemical property and difficult intermittent discharge. With the development of China’s pharmaceutical industry, pharmaceutical wastewater has gradually become one of the important sources of pollution. How to treat this kind of waste water is a difficult problem of environmental protection today.
