What are the general industrial solid wastes?

Industrial solid wastes can be divided into general industrial wastes, such as blast furnace slag, steel slag, red mud, nonferrous metal slag, fly ash, coal cinder, sulfuric acid slag, waste gypsum, desulfurization ash, carbide slag, salt mud and other industrial hazardous solid wastes, that is, hazardous solid wastes. Industrial solid waste refers to the solid waste produced in industrial production activities. A kind of solid waste, referred to as industrial waste for short, is all kinds of waste residue, dust and other wastes discharged into the environment during industrial production.

Passive storage of industrial waste not only occupies a lot of land, but also wastes manpower and material resources. Many industrial waste residues contain water-soluble substances, which pollute soil and water bodies through leaching. Powdered industrial wastes fly with the wind, polluting the atmosphere, and some even emit odor and toxic gases. Some wastes even block rivers, pollute water systems, affect biological growth and endanger human health.

Industrial hazardous solid waste management measures: Industrial hazardous solid waste cannot be discharged at will. In order to strengthen management, many countries have formulated management regulations. The Hygienic Standard for the Design of Industrial Enterprises and the Trial Standard for the Discharge of Industrial "Three Wastes" promulgated by China also provide principles for the management and disposal of industrial hazardous solid wastes.

1. Establish a system of identification, marking and registration, so that hazardous wastes will be managed by special personnel from discharge to final disposal, and files will be kept. 2. Determine safe and economical collection, storage and transportation methods and systems to ensure that hazardous wastes will not pollute the environment before final disposal. 3. Choose a safe and economical disposal method and place. 4. Formulate evaluation standards for the collection, storage, transportation and final disposal of hazardous wastes.
