The principle and wide application of biological wastewater inactivation treatment system
Date: 2025-08-20Read: 7
The biological wastewater inactivation treatment system is a technology specifically designed to kill pathogenic microorganisms such as bacteria and viruses in wastewater, ensuring that the wastewater meets safety standards before discharge or reuse. The core principle is based on the destruction of microbial cell structure and genetic material, mainly achieved through three methods: physical, chemical, and heat treatment. Physical methods include filtration (intercepting microorganisms through filter membranes), ultraviolet radiation (damaging genetic material to prevent reproduction), and ion radiation (such as gamma rays damaging cell structure); Chemical methods use chemicals such as chlorine to generate hypochlorous acid (which oxidizes cell membranes and proteins), ozone oxidation (which directly destroys microbial structures), or ozone/UV mixed treatment (which generates strong oxidative hydroxyl radicals); Heat treatment is the mainstream method, which inactivates microorganisms at high temperatures through steam sterilization or thermal drying (bacterial enzyme denaturation, viral DNA/RNA bond cleavage).
This system is widely used in biopharmaceutical companies, laboratories, research institutes, and animal rooms to treat wastewater containing live toxins (such as vaccine production waste, animal urine, or dissection waste). Through automated high-temperature sterilization, it ensures that pathogens are completely inactivated and achieves safe discharge; The application advantages include high sterilization reliability, easy operation, and the ability to integrate acid-base neutralization processes to meet different processing needs.
Overall, the biological wastewater inactivation treatment system enhances the microbial inactivation effect through a combination method, supports compliant discharge or reuse of wastewater, and plays a key role in ensuring public health and environmental safety.
