Wastewater Sources and Hazards
Biopharmaceutical companies, laboratories, research institutes, etc., discharge live toxic wastewater containing live bacteria and viruses, which is highly hazardous and requires sterilization before being discharged into the next level of the wastewater treatment system.
Process Flow
The system is fully automatic and can switch between manual and automatic operation. During automatic operation, the system can work according to the preset process. The process flow includes wastewater inflow, water inflow stop, heating, inactivation timing, inactivation completion, cooling, and wastewater discharge after inactivation is complete. In manual operation, the user can operate the system manually; during wastewater inflow, there is a liquid level control, which automatically stops when a certain liquid level is reached. The liquid level can be set on the operating interface. During manual operation, high and low liquid level alarms will be set to ensure the normal operation of the equipment; during inactivation, steam is introduced into the tank to heat the wastewater using a steam injector and steam-water mixing method. The steam usage point is equipped with a steam trap and can be manually controlled; when the inactivation temperature is reached, the insulation program starts, and steam is intermittently introduced to maintain the temperature, while the steam injector in the tank ensures uniform heat transfer, quickly and efficiently completing the heating and inactivation process; the live toxic wastewater first enters the inactivation tank through self-flow for inactivation. The inactivation tank program is divided into six stages: liquid inflow, heating, inactivation, pressure relief, cooling, and discharge.
Process Principle
High temperature has a significant lethal effect on microorganisms. In wastewater discharged from biosafety laboratories or biopharmaceutical companies, most viruses and bacteria can be killed at 90-120℃ for 30-60 minutes. Thermal sterilization mainly uses high temperature to denature or coagulate the cells, inactivating enzymes and causing bacterial death. However, before bacterial coagulation, subtle changes such as single-strand DNA breaks have already occurred, which may be the main lethal factor. The process of chemical bonds in viral DNA and RNA absorbing heat and breaking at high temperatures is the core of viral inactivation at high temperatures. The chemical structures of bacterial proteins, nucleic acids, etc., are connected by hydrogen bonds, which are relatively weak chemical bonds. When the cells are heated, the hydrogen bonds are destroyed, and the structures of proteins, nucleic acids, enzymes, etc., are also destroyed, losing their biological activity and leading to bacterial death. In addition, high temperatures can also lead to loss of cell membrane function, causing leakage of small molecules and degraded ribosomes.
