Abstract

Abstract

This paper innovatively presents the design and implementation of an on-site thermal treatment system for medical organic waste liquid at the source. The system achieves a tight integration of automatic control with energy-efficient and eco- friendly operation at the equipment level. It enables immediate treatment of waste liquid at the source， leading to a reduction in storage and transportation volumes by over 95%. Consequently， it eliminates potential safety hazards and environmental risks associated with traditional waste liquid management and treatment processes. The system design primarily consists of four modules： a waste liquid identification module， a graded thermal treatment module， a heat recovery module， and a tail gas purification module. Among these， the specially developed graded thermal treatment technology can effectively process hazardous medical organic waste liquids with different compositions and calorific values. Finally， on-site treatment experiments were conducted on four typical types of hazardous medical organic waste liquids to validate the feasibility of the system. The results demonstrate that the system can achieve effective treatment of hazardous medical organic waste liquid， meeting the safety and environmental protection requirements while offering certain economic benefits.
- medical organic waste liquid,
- energy-efficient and eco- friendly,
