Example Analysis of Hazardous Waste Identification for Paste Flue Gas Treatment Slag
Taking the illegal dumping of paste like solid waste in an environmental event as the research object,the source of solid waste was determined through composition,leaching toxicity,and corrosive pH testing,which was consistent with the collected data and information.By comparing the preparation instructions of the"Hazardous Waste Identification Standard(Draft for Soliciting Opinions)"to determine the reference limit value of the leaching toxicity thallium index,and based on the detection results of the sample leaching toxicity thallium index,it is determined that the solid waste is classified as HW30 hazardous waste with a waste code of 900-000-30.This study,through the analysis of practical cases of environmental events,points out that when the existing identification criteria are infinite,potential hazardous characteristics should be comprehensively considered for the damage to the ecological environment and human health.According to the principles mentioned in the preparation instructions,indicator reference limits should be set,aiming to provide a reference technical work plan for hazardous waste identification units and technical personnel.
