the comprehensive utilization of bulk solid waste is an important part of the energy conservation and environmental protection strategic emerging industry. it advocates the comprehensive utilization of solid waste such as sludge, sediment, tailings, fly ash, coal gangue, red mud, smelting slag, industrial by-product gypsum, calcium carbide slag, construction waste, etc. to carry out the reduction, value-added and harmless work.
in recent years, with the increasing emphasis on energy conservation and environmental protection, the comprehensive utilization of bulk solid waste in china has achieved remarkable results. however, by the end of the 11th five year plan, the sludge produced in the sewage treatment process has not been effectively cured;
the treatment and disposal of heavy metal polluted or eutrophicated water sediment has not formed the industry standard;
as a large amount of industrial solid waste discharged and piled up, the comprehensive utilization rate of tailings is only 14%. the tailings pond occupies a large amount of land resources, and the dangerous, sick and mined out underground mine tunnels have become the hidden danger of seriously endangering the safety of local people's lives and properties;
red mud, as a kind of high corrosive industrial solid waste, its comprehensive utilization rate is as low as 4%, which is regarded as a difficult environmental protection problem in the world.
how to reduce sludge, sediment, tailings and red mud, and even increase the value of sludge, is the priority of hengyuan waste.
in addition, although the comprehensive utilization rate of large industrial solid wastes such as fly ash, coal gangue and industrial by-product gypsum is high, there is still a problem of low added value of products; how to realize the high added value of such large industrial solid wastes is also the focus of our attention.
