国家通过出台火电行业脱硫、脱硝及除尘补贴电价政策,极大调动了火电企业建设、改造环保设施的积极性,目前已基本解决了火电行业脱硫、脱硝问题。继火电后,水泥、钢铁行业的脱硫、脱硝已成为完成大气污染物减排任务、改善环境质量的关键领域之一,但目前这两大行业还没有类似火电行业的相关扶持政策,环保设施运行成本高,企业治污投入大,水泥、钢铁等重污染行业亟需国家尽快出台脱硫、脱硝等环保激励政策及环保设施建设运行的税收优惠政 Through the introduction of thermal power industry desulfurization, denitrification and dust subsidies policy, which greatly mobilized the construction of thermal power companies, environmental protection facilities to transform the enthusiasm has now basically solved the thermal power industry desulfurization and denitrification issues. Following thermal power, the desulphurization and denitrification in the cement and steel industries have become one of the key areas for accomplishing the tasks of reducing atmospheric pollutants and improving the environmental quality. However, at present, there are no relevant supporting policies similar to the thermal power industry in these two major industries. The operation of environmental protection facilities High cost, huge corporate pollution control, heavy pollution industries such as cement, steel and other urgent need for the state to introduce environmental incentives such as desulfurization, denitrification and environmental protection facilities construction and operation of tax incentives
