Design and Implementation of an Energy-Saving Onsite Thermal Treatment System for Hazardous Medical Organic Waste Liquid
This paper presents the design and implementation of an energy-saving onsite thermal treatment system for hazardous medical organic waste liquid. The system integrates automatic control with energy-efficient and eco-friendly operation, enabling immediate treatment at the source and reducing storage and transportation volumes by over 95%. It comprises four modules: waste liquid identification, graded thermal treatment, heat recovery, and tail gas purification. The graded thermal treatment technology effectively processes waste liquids with varying compositions and calorific values. On-site experiments were conducted on four typical medical organic waste liquids over one year. Results demonstrated effective treatment meeting safety and environmental requirements, with dioxin concentrations below 0.1 ng-TEQ/m³ and CO, NOx, and SOx emissions within permissible limits. The system offers economic benefits by eliminating long-distance transport and centralized treatment costs. This approach addresses the limitations of traditional long-chain, manual-intensive disposal methods, which pose significant safety and environmental risks.
