Study on Collection and Disposal Technology of Laboratory Hazardous Liquid

The collection and disposal of laboratory waste liquid are important and difficult parts for hazardous waste management in laboratory. Based on summarizing the practical experience, in-depth survey and conducting experiments, the collection and disposal technologies of laboratory waste liquid were systematically investigated. The classification method and process were proposed, and requirements of the material, size and shape of the packaging container, the sorting and packing process of disposal unit, and the method of pre-processing were analyzed. Finally, the superiority disposal technologies were pointed out based on comparing existing technologies such as physiochemical methods, biological methods and incineration methods.
