Chemical Teatment of Hazardous Waste
Chemical treatment involves using chemical agents to break down hazardous components in medical waste into less harmful or harmless substances. This method plays a crucial role in reducing biohazardousness, volume, and weight of medical waste, ensuring its safe disposal. The main function of chemical degradation agents is to chemically react with specific substances in biological waste, breaking them down into harmless or less harmful substances. For example, certain strong oxidizers can oxidize and decompose organic pollutants in medical or biological waste into carbon dioxide, water, and inorganic salts.
Types of Chemical Treatment for Different Hazardous Wastes
Chlorine-containing Disinfectants
(e.g., Sodium Hypochlorite)
Peroxyacetic Acid
Formalin Immersion
Glutaraldehyde
Acid-Base Neutralization
Redox Method
Requirements for Chemical Treatment Vessels
Material
Containers should be corrosion-resistant, such as glass or polytetrafluoroethylene (PTFE) for acidic or alkaline waste, and stainless steel for high-temperature treatments.
Temperature Resistance
Containers should withstand temperatures up to 134°C for sterilization processes.
Sealing
Containers must be tightly sealed to prevent leakage of harmful substances, especially for volatile chemicals like chlorine and peroxyacetic acid.
Labeling
Properly label containers with waste type, chemical treatment method, and associated hazard warnings.
Benefits of Chemical Treatment
Protects Operator Safety
Prevents Accidents
Minimizes Environmental Pollution
Standardizes Treatment Process
Procedure for Chemical Treatment
Precautions During Use and Operation
Operator Safety
Always adhere to safety procedures when using chemical reagents, especially those that are toxic, corrosive, or irritating (e.g., ethylene oxide or peroxyacetic acid).
Chemical Reagent Management
Store chemicals properly, keeping them in controlled environments to prevent degradation or accidents. Reagents should be handled carefully during transport and use to avoid spillage or overuse.
Equipment Maintenance
Regularly inspect treatment vessels, pipes, seals, and other components for damage. Ensure that operating parameters like temperature, pressure, and flow rate are properly monitored.
Disposal After Chemical Treatment
Monitoring
Test the treated waste to ensure it meets safety standards. Microbiological and chemical tests can confirm the absence of harmful pathogens or excessive chemical residues.
Container Disposal
After use, containers for chemical reagents should be cleaned and properly disposed of. Plastic containers can be recycled if clean, while glass containers should be cleaned or treated as glass waste.
Final Disposal
Waste that meets safety standards can be disposed of through landfill or incineration. If the standards are not met, re-evaluate and adjust treatment parameters or methods.
Key Considerations for Choosing Chemical Treatment Products
International Standards and Regulations
WHO Guidelines
WHO emphasizes the need for safe, effective, and environmentally friendly methods of medical waste treatment. Chemical treatments should ensure the complete inactivation of pathogens while minimizing environmental impact.
Chinese Regulations
China’s Regulations on the Management of Medical Waste set out strict standards for medical waste treatment facilities, including requirements for chemical treatment, equipment, and operator qualifications.
