What Is Hazardous Industrial Waste?
Industrial solid waste  refers to solid waste generated in industrial production activities. A category of solid waste, referred to as industrial waste, is a variety of waste residues, dust and other wastes discharged into the environment during industrial production. Can be divided into general industrial waste (such as blast furnace slag, steel slag, red mud, non-ferrous metal slag, fly ash, coal slag, sulfuric acid slag, waste gypsum, salt mud, etc.) and industrial hazardous solid waste.
- Industrial hazardous solid waste refers to industrial solid waste generated in industrial production activities that can cause real or potential harm to the health of the population or the environment 
- There are many types of industrial hazardous solid wastes. In order to facilitate management, these wastes are generally divided into the following categories:
- Toxic: Wastes that test positive for any particular type of metabolic activity;
- Industrial hazardous solid waste cannot be arbitrarily discharged. In order to strengthen management, many countries have formulated management regulations. The "Sanitary Standards for the Design of Industrial Enterprises" and the "Trial Standards for the Discharge of Industrial" Three Wastes "" promulgated by China also provide principles for the management and disposal of industrial hazardous solid wastes.
The main management measures are:
- Establish a system of identification, labeling and registration, so that hazardous wastes are managed by special persons from the beginning of discharge to the end of disposal, and archives are established.
- Determine safe and economical collection, storage, and transportation methods and systems to ensure that hazardous waste will not pollute the environment before final disposal.
- Choose a safe and economical disposal method and disposal site.
- Formulation of evaluation criteria for the collection, storage, transportation and final disposal of hazardous wastes 
- Industrial hazardous solid waste treatment methods Industrial hazardous solid waste can be divided into toxic, flammable, corrosive and highly chemically reactive. The methods commonly used by various countries to treat hazardous solid waste include incineration, landfill, chemical treatment, solidification, biological treatment, and marine disposal. 
- With the development of industrial production, the discharge of industrial hazardous solid waste is increasing. They are flammable; easily exposed; toxic; corrosive; have strong chemical reactivity; can spread diseases and so on. In order to eliminate the hazards of industrial hazardous solid wastes, it is necessary to establish identification, marking and registration systems; determine safe and economical collection, storage and transportation methods and systems; and choose safe and economical disposal methods.
