Energy measurement and monitoring, timely detection and elimination of the adverse impact on the environment. 5.4 semi-solid and liquid solid waste containing non-ferrous metals transport, storage, should be loaded into special drums, tanks and other containers or tanker trucks. The storage and transportation of hazardous waste containing non-ferrous metals should comply with the requirements of GB18597.HJ2025 and other standards and specifications. 6 Enterprise management requirements Solid waste containing non-ferrous metals recycling enterprises should have the following basic requirements: a) is established by law, with non-ferrous metal solid waste comprehensive use of business enterprise legal person qualification. b) should be configured with the size of the organization and non-ferrous metal solid waste comprehensive utilization of project type appropriate management personnel, professional and technical personnel, technical workers and other personnel. Relevant staff and managers should master the provisions of relevant national policies and regulations, standards and norms. c) there should be a fixed place and the necessary recycling. Storage. Treatment and environmental protection and safety facilities and equipment, to meet the requirements of national or local environmental protection and safety protection standards and norms. d) There should be sound personnel management, production management, quality management. Safety and emergency management and environmental management and other management systems or management systems. e) The amount of solid waste handled should be compatible with the recycling capacity and pollution prevention capacity. 7 Common recycling techniques 7.1 Physical treatment According to the basic physical properties of solid waste containing non-ferrous metals, through physical methods to change the shape of solid waste, but does not destroy the solid waste composition of a treatment method, including compaction, crushing, sieving, sorting, dewatering, evaporation, extraction, adsorption and other methods. Prior to recycling and utilisation, non-ferrous solid wastes can be subjected to the necessary initial treatment, which includes processes such as crushing and sorting. For non-ferrous metal sludge and semi-solid waste, mechanical dewatering and reduction can be carried out by means of press filtration, or drying and dewatering reduction can be carried out using equipment such as hot ovens and steam drying ovens. 7 Commonly used recycling techniques 7.1 Physical treatment According to the basic physical properties of solid waste containing non-ferrous metals, a treatment method that changes the shape of solid waste by physical means, but does not destroy the composition of solid waste, including compaction, crushing. Sieving, sorting, dewatering, swallowing, extraction, adsorption and other methods. Prior to recycling and utilisation, non-ferrous solid wastes can be subjected to the necessary initial treatment, mainly consisting of crushing and sorting processes. For non-ferrous metal sludge and semi-solid waste, mechanical dewatering and reduction can be carried out by means of press filtration, or drying and dewatering reduction can be carried out by using equipment such as hot drying ovens and steam drying ovens. 7.2 Chemical treatment According to the basic chemical properties of non-ferrous solid waste, the chemical transformation of it, so as to obtain valuable metals or metal compounds and other substances treatment methods, including redox, electrolysis, electrowinning, extraction, separation, leaching and other wet metallurgical methods, as well as roasting, smelting and other pyrometallurgical methods. Typical non-ferrous metal-containing solid waste utilization processes are listed in Appendix A. 7.3 Biological treatment The use of biochemical action, the non-ferrous solid waste treatment, so as to obtain valuable substances or energy - a treatment method, such as microbial metallurgy. 8 Ecological and environmental protection requirements 8.1 Construction requirements The site of the recycling project of solid waste containing non-ferrous metals should meet the requirements of the ecological protection red line, and determine the environmental quality objectives and the corresponding environmental control, taking into account the current situation of environmental quality and the requirements of the relevant planning functional zoning. Pollutant emission control requirements; the project should be able to maintain stable environmental quality and should not be lower than the environmental quality standards of air, soil and water. The project shall build supporting environmental protection facilities in accordance with the requirements of "three simultaneous" environmental protection and apply for environmental protection inspection and acceptance upon completion of the project in accordance with the law. 8.2 Pollution control requirements 8.2.1 In the recycling process of solid waste containing non-ferrous metals, the air.
