The reporter learns from the provincial ecological environment agency: to promote our province to improve atmospheric environmental quality, accelerate the development of high quality iron and steel industry in our province, provincial ecological environment agency provincial development and reform commission, provincial Ministry of Industry and Information Technology department, the provincial financial department, the province transportation hall and other departments issued "shaanxi steel ultra-low emissions retrofit scheme" (hereinafter referred to as the "scheme"). The plan defines the overall requirements, implementation steps, key tasks and implementation guarantees for the implementation of ultra-low emissions in the steel industry in our province, so as to ensure that the transformation of ultra-low emissions in the steel industry is completed on time.

"Plan" pointed out that, in accordance with the "low transform a batch, reaches a batch, backward a batch of" requirements, the scope of the modification of the whole province into seven iron and steel enterprise orderly implementation of ultra low emission reform, by the end of "difference" pollutant total amount further cuts in iron and steel industry, basic implementation in emission permits, for the whole process of environmental management and communities, effectively improve the quality and efficiency of iron and steel industry development, promote the environmental air quality continues to improve, provide strong support to win the blue sky battle.

According to the emission characteristics of the industry, the plan puts forward indicators, limits and control measures for the organized emission, the unorganized emission and the transportation of bulk materials and products, so as to realize the whole process and the whole process of environmental management. Sintering machine head, pellets roasting gas concentration of particulate matter, sulfur dioxide, nitrogen oxide emissions average hours are not more than 10 mg/m3, 35 mg/m3, 50 mg/m3, the other major sources of pollution in principle is not more than 10 mg/m3, 50 mg/cubic meters and 200 mg/m3, Effective measures such as airtight and closed shall be taken in material storage, transportation and production process to realize effective control of unorganized discharge; Bulk materials and products are transported by clean means, such as railway, waterway and pipeline. The proportion of clean transportation is no less than 80%, and stricter requirements are put forward for monitoring and control.

In addition, the plan also proposed to increase the tax, capital, price, financial, environmental protection and other policy support for enterprises to achieve ultra-low emissions transformation. By the end of 2022, significant progress had been made in upgrading the province's steel enterprises to achieve ultra-low emissions. Four steel enterprises in guanzhong had completed the upgrading, and three steel enterprises in southern shaanxi had completed 40% of the upgrading. By the end of 2025, all steel enterprises in the province that have been included in the transformation will have completed the transformation of ultra-low emissions.
