Comprehensive Utilization Of Solid Waste Are Improved
Planning a large amount of industrial solid waste in China refers in various industrial
fields in production activity in production in 10000000 tons of above, to the environment and the safety is greatly influenced by the solid waste, mainly including: tailings, coal gangue, fly ash, slag, red mud and industrial by-product gypsum, calcium carbide slag.
" Planning" proposed, to 2015, a large amount of industrial solid waste comprehensive utilization reached 16tons, the comprehensive utilization rate reached 50%, wherein the tailings comprehensive utilization rate should achieve 20%, fly ash, coal gangue comprehensive utilization rate to 70%, the annual output value of 500000000000Yuan, provide 2500000 jobs.
In the coal gangue," Twelfth Five-Year Plan" period, focusing on research and development of coal gangue cement filling for cementitious materials of mass production technology, coal gangue as substitute of clay tile and other ceramic products technology, coal gangue in compound fertilizer production technology, production of composite water purification agent and other high-value materials, chemical products. Focus on the promotion of demonstration coal gangue is not on the wells replacement pillar, coal gangue in the production of aluminum silicate fiber, coal gangue fired hollow brick, coal gangue sintering ceramsite technology, including Bai Gan ( hard rock ) and black rock ( combustible gangue ) mixed coal gangue in large-scale low-cost separation technology.
Fly ash,"12th Five-Year Plan", focus on Inner Mongolia, Shanxi, fly ash produced and stockpiled concentration region of the comprehensive utilization of fly ash. High volume fly ash concrete pavement materials and technology; innovation breakthrough from fly ash separation of carbon, glass beads and other valuable component of high value-added products and technology and equipment, development of high aluminum fly ash mass production of alumina and other chemicals, building materials products and complete sets of technology and complete sets of equipment; development of high aluminum fly ash and low energy consumption in smelting silicon aluminum alloy technology. Focus on the promotion of the technology include: fly ash as road base course material technology, instead of clay to build highway embankment technology, a large amount of fly ash concrete technology and low clinker fly ash cementitious material technology, fly ash low energy refinement and modification of upgrading technology, production of fly ash sintered products, the fly ash aerated concrete and other building materials of fly ash production technology.
Along with our country infrastructure, the rapid growth of the scale,hongxing heavy crusher, sand maker, milling machine, fly ash, coal gangue production line production line for the bulk of industrial solid waste in cement, concrete and other building materials, wall materials application provides vast market space, will effectively promote the bulk of industrial solid waste comprehensive utilization.
