Discussion on Management and Disposal Technology of Corrosive Hazardous Waste

Abstract

Hazardous waste is an important part of the ecological system and the environmental community. Corrosive hazardous waste accounts for a large proportion of hazardous wastes. In addition to waste acid(HW34) and alkali(HW35), it also involves 8 other types and 13 subcodes. Corrosive hazardous waste has various physical states, involves thousands of chemical substances, and can have all kinds of hazardous properties such as toxicity, flammability, oxidation, reactivity, and explosive. The classification, detection, identification, transportation, storage and disposal technologies of corrosive hazardous waste are discussed for hazardous waste generating units, disposal units and regulatory authorities. 

Hazardous waste refers to solid or liquid waste with at least one characteristic of toxicity, corrosiveness, flammability, reactivity and infectiousness. The scientific management and effective governance of hazardous wastes have become a major issue faced by all countries in the world today. Corrosive hazardous waste(CHW) accounts for a large proportion of hazardous waste, which is sometimes referred to as corrosive waste. At present, there are many domestic and foreign literatures on the disposal of various waste acids and waste alkalis, but there is no literature on the subject of corrosive hazardous waste[1] in China.
