Energy consumption per ton of steel decreased year over year, and external discharges of wastewater and waste gas were significantly reduced.
A reporter recently learned from the Hebei Provincial Metallurgical Industry Association that, 2015 In Hebei Province, key steel enterprises have reduced production costs through energy conservation and consumption reduction, with the comprehensive energy consumption per ton of steel continuing to decline. The comprehensive energy consumption per ton of steel at these key steel companies stands at… 563.6 kilogram Standard coal / tons, down year-on-year 6.96 kilogram Standard coal / tons, annual savings of 131.08 Ten thousand tons of standard coal. 2015 Year, national comprehensive energy consumption per ton of steel 571.85 kilogram Standard coal / tonnes; the comprehensive energy consumption per tonne of steel at key steel enterprises in Hebei Province is lower than the national average. 8.25 kilogram Standard coal / tons, indicating that the energy consumption of key steel enterprises in Hebei Province is at a relatively favorable level.
The Hebei Provincial Metallurgical Industry Association pointed out that the association’s key member enterprises… 2015 In recent years, efforts to strengthen environmental protection have been consistently intensified, resulting in a substantial year-on-year reduction in the total volume of wastewater discharged by enterprises and a corresponding decline in the cumulative emissions of major pollutants in wastewater. ; Emissions of sulfur dioxide, smoke, and particulate matter in exhaust gases decreased year over year. ; Key statistical steel enterprises have intensified efforts to recover and utilize combustible gases, with the utilization rates of blast furnace gas and converter gas both increasing year on year.
Analysis 2015 Annual data, Hebei Provincial Metallurgical Industry Association 70 Total water consumption of member enterprises 1995131.29 Cubic meters; the total annual intake of fresh water decreased year-on-year. 1.11% , its total recycled water usage 1945705.78 cubic meters, and the water reuse rate is 97.52% , year-on-year growth 0.22% 。2015 year 1 Month~ 12 Cumulative new water consumption per ton of steel for the month 2.53 cubic meter / tons, down year-on-year 1.75% Meanwhile, steel enterprises have also recorded year-on-year declines in the discharge of wastewater, exhaust gases, and their major pollutants. 2015 year 1 Month~ 12 Month, 15 The total volume of wastewater discharged by key member steel enterprises is 3377.39 cubic meters, with a year-on-year decline of 16.70% 。54 Member enterprises submit sulfur dioxide emission data. 160699.22 tons, year-on-year decline 14.95%;53 Smoke and dust emissions of member enterprises 67595.53 tons, year-on-year decline 5.75%; Dust emission volume 105169.42 tons, down year-on-year 6.05% 。
Moreover, member steel enterprises have broadly intensified their efforts to utilize solid waste resources. 2015 Year, the utilization rate of steel slag is 98.93% , up year-on-year by 0.31 percentage points ; The utilization rate of blast furnace slag is 99.70% , up year-on-year by 0.43 percentage points ; The utilization rate of iron-containing dust and sludge is 99.87% , unchanged year over year.
In addition, 2015 year 1 Month~ 12 The blast furnace gas utilization rate for the month is 97.98% , up from the same period last year 0.51 percentage points ; The utilization rate of converter gas is 95.76% , an increase compared to the same period last year 1.02 percentage points ; The utilization rate of coke oven gas is 99.30% , a decrease compared with the same period last year 0.25 percentage points.
Wang Dayong, Vice President and Secretary-General of the Hebei Provincial Metallurgical Industry Association, pointed out that this year, the association’s key member steel enterprises will further intensify efforts to recover and utilize combustible gases. They will continue to increase investment in environmental protection and pollution control, ensure the effective implementation of all relevant measures, and advance the green development of the steel industry.
