Hazardous waste (referred to as hazardous waste) refers to the production waste which is metabolized in the process of industrial production and listed in the national hazardous waste list. It is a kind of material with great harm. Production wastes which are not listed in the list but are identified as having one or several hazardous characteristics of corrosivity, toxicity, leaching toxicity, flammability, reactivity and infectivity also belong to hazardous wastes. The main sources of hazardous wastes are various industrial production processes. These industrial hazardous wastes will pollute the soil, air and water sources to a great extent, seriously endanger the development of society and the survival of human beings, and the harm is often latent, long-term and catastrophic.
