Pharmaceutical factory comprehensive sewage treatment equipment: protecting green waters and green mountains and promoting green development

With the rapid development of my country's pharmaceutical industry, the problem of wastewater generated by pharmaceutical factories in the production process has become increasingly prominent. Pharmaceutical wastewater has complex components and many types of pollutants. If it is not properly treated, it will cause serious pollution to the environment. This article will deeply explore the selection and configuration of comprehensive sewage treatment equipment in pharmaceutical factories and its important role in environmental protection. 2. Characteristics and challenges of pharmaceutical factory wastewater Pharmaceutical factory wastewater usually contains a large amount of organic matter, inorganic matter, microorganisms and some toxic and harmful substances. These wastewaters have the following characteristics: 1. Complex composition: Contains a variety of drug residues, solvents, acids and alkalis and other chemical substances. 2. High content of organic pollutants: COD and BOD values ​​are high and require efficient treatment. 3. Difficulty in biodegradation: Contains difficult biodegradable substances, which increases the difficulty of treatment. 4. Large fluctuations in pollutant concentration: The composition and concentration of wastewater from different pharmaceutical processes vary significantly. 3. Selection and configuration of comprehensive sewage treatment equipment In view of the characteristics of pharmaceutical factory wastewater, the selection and configuration of comprehensive sewage treatment equipment is crucial. 1. Pretreatment equipment: - Screen: Used to intercept large particles in wastewater to prevent subsequent equipment from clogging. - Sedimentation tank: Separate suspended matter in wastewater by gravity sedimentation to reduce the burden of subsequent treatment. - Regulating tank: Balance wastewater quality and water volume to provide stable conditions for subsequent treatment. 2. Main treatment equipment: - Activated sludge equipment: Use microorganisms in activated sludge to degrade organic matter in wastewater. This equipment has good treatment effect and strong stability, and is a common equipment for pharmaceutical wastewater treatment. - Anaerobic digestion equipment: Through the action of anaerobic bacteria, organic matter is fermented to produce biogas and purify sludge, which is conducive to resource utilization. - Aeration tank: By injecting air into the wastewater, the oxygen content is increased, which promotes the growth of microorganisms and the degradation of organic matter. - Membrane bioreactor (MBR): Combine membrane separation technology and biological treatment technology to achieve efficient organic matter degradation and solid-liquid separation. 3. Deep treatment equipment: - Ozone oxidation equipment: Use the strong oxidizing property of ozone to further degrade difficult-to-degrade organic matter and improve the wastewater treatment effect. - Advanced oxidation process (AOP): Combine advanced oxidation technologies such as ozone and ultraviolet light to deeply treat difficult-to-degrade organic matter. - Activated carbon adsorption equipment: Use the adsorption properties of activated carbon to remove odor and residual organic matter in wastewater. IV. Equipment characteristics and selection principles When selecting comprehensive sewage treatment equipment, the following characteristics and application principles are crucial: 1. High degree of automation: Select equipment with a fully automatic control system to reduce manual intervention and improve treatment efficiency. 2. Strong treatment capacity: According to the wastewater output and treatment requirements of the pharmaceutical factory, select equipment with sufficient treatment capacity. 3. Compliance with environmental standards: The equipment should be able to meet national and local environmental protection standards to ensure the stability of the discharged water quality. 4. Corrosion resistance and reliability: Since pharmaceutical wastewater contains a variety of chemical substances, the equipment needs to have good corrosion resistance and reliability. V. Maintenance and management In order to ensure the efficient operation and long-term stability of the comprehensive sewage treatment equipment in pharmaceutical factories, the following maintenance and management measures are crucial: 1. Regular inspection: Regularly inspect the equipment to ensure its normal operation and timely discover and solve faults. 2. Regular cleaning: Regularly clean the equipment to prevent blockage and pollution and ensure the treatment effect. 3. Calibration and maintenance: Calibrate and maintain the equipment regularly to ensure the working performance and treatment effect of the equipment. VI. Pharmaceutical wastewater treatment under the concept of green development In the context of the new era, green development has become an important concept for the development of our country's society. As the core link of the pharmaceutical industry, pharmaceutical factories should actively respond to this concept and achieve efficient treatment and resource utilization of wastewater by adopting advanced comprehensive sewage treatment equipment and technology. VII. Conclusion The comprehensive sewage treatment equipment of pharmaceutical factories is the key to achieving efficient treatment of pharmaceutical wastewater and environmental protection. By rationally selecting and configuring equipment and strengthening maintenance and management, pharmaceutical factories can improve economic benefits while protecting the environment and achieving sustainable development. In future development, the pharmaceutical industry should continue to promote technological innovation, actively explore new methods and new ideas for wastewater treatment, and contribute greater strength to building a beautiful China.
