Hebei Xinda Iron and Steel Group Co., Ltd. attaches great importance to environmental protection and circular economy development, always adhering to the development concept of "innovation, green, open and win-win", and earnestly implementing the series of measures of "sword to cut pollution, focus on implementation", not only shows the attitude of Xinda people to actively fulfill social responsibilities, but also reflects the determination, confidence and ambition of Xinda Sword to cut pollution and in-depth environmental governance.

Since the 18th National Congress of the Communist Party of China, laws and regulations on the ecological environment have been continuously improved, and the ecological civilization system with strict prevention at the source, strict management in the process, and severe consequences has been gradually improved. Under the guidance of increasingly strict environmental protection standards, Xinda has hit hard, scientific pollution control, comprehensive policies, and invested 5.4 billion yuan to introduce advanced environmental protection technologies and equipment such as SDS dry desulfurization, SDA semi-dry desulfurization, CFB circulating fluidized bed desulfurization, SCR denitrification, LT dry dust removal process, etc. All the material fields have built mechanized fully enclosed material shed. Key dust production points are equipped with intelligent dry fog dust suppression system, which has achieved ultra-low emission in the whole process. A large number of hydrogen energy and pure electric tractors were introduced, and new energy vehicles accounted for more than 80% of the transport volume of clean transportation. Become the first iron and steel enterprise in Hebei Province to pass the A-level enterprise review evaluation.

We will strengthen green and low-carbon driving forces for scientific and technological innovation. The integrated platform of environmental protection management and control was independently developed to simulate the status of on-site production and environmental protection equipment through 3D modeling technology. The discrete data of 3447 environmental protection monitoring points in the whole factory area were completely collected into the database, and the online monitoring data, main production parameters and load data of environmental protection facilities were presented in real time on the large screen to guide the staff to carry out environmental protection scheduling. Ensure stability to achieve ultra-low emission standards. The research and development of intelligent environmental protection combustion control scheme of hot blast stove has reduced sulfur dioxide content in flue gas by 2.3% on average, particulate matter emission by 66.03% on average, and gas saving by 4.8% per hour on average. Research and development of intelligent fog pile fog gun system, the use of integrated monitoring unit to sense environmental data, high pressure pump and fine atomizing nozzle can spray small artificial fog particles in a large area, adsorption, aggregation and settlement of PM2.5 and PM10 dust particles in the air, reduce unorganized emissions.

Explore a circular green industrial chain from resources, products to renewable resources. The industrial solid waste resource treatment plant actively consumes industrial wastes such as slag, desulfurized gypsum and tail ore, and can produce 3 million tons of slag fine powder annually. We strive to build an "urban mine" industry, build a large solid waste environmental protection project with an annual steel slag treatment capacity of 2 million tons and processing 240,000 tons of scrap steel, achieve solid waste does not leave the factory, and won the "Hebei Province waste free enterprise (factory)". At the same time, the implementation of gas, steam, industrial sewage recycling and recycling projects, the construction of 145MW supercritical gas power generation, 100MW high temperature and ultra-high pressure, 110MW ultra-high temperature sub-critical gas power generation, steam waste heat generator units and 330KW photovoltaic power generation system, self-generating rate has increased year by year; Construction of large-scale sewage treatment plant, production of domestic sewage after deep treatment to meet the drinking standard, won the title of "Hebei Province water-saving enterprise"

Nowadays, "ecology" has become the "precious wealth" of Xinda, and "green" has become the "most beautiful background color". The whole plant forest green space 120,000 square meters, more than 500,000 trees and shrubs, very Jiangnan characteristics of the "blue and white porcelain" cooling tower and the blue sky and white clouds integrated. With a total length of 2,500 meters, Quanxin Avenue has a green area of more than 30,000 square meters. The trees and forests represented by Huashan pine, Fagolia and ginkgo, and the bushes represented by malonia, crape Myrtrea and cloves are enchanting and beautiful, which attract tourists to come and enjoy the scenery.

The subcritical forest park breeding yak, sika deer and other animals that are extremely harsh on the living environment. The water in the water garden is clear and green, and the fish is shallow and shallow, vividly restoring the natural state of flowers, grass, water and birds. The steel mill miraculously presents the beautiful scenery of "the sky is gray, the wild is boundless, and the wind blows the grass to see cattle and sheep".

People are not old, scenery here alone. On the road to green development, mountains and rivers are bursting with excitement. Xiongguan road is really like iron, and now step over from the beginning. On the way to transformation and upgrading, the flag will always be high. In the future, Hebei Xinda Group will firmly establish and practice the concept that green water and green mountains are gold and silver mountains, unswervingly take the road of ecological priority and green development, accelerate green technology innovation and the promotion and application of advanced green technology, and build a green low-carbon circular industrial system. Build a steel industry cluster with low input of production factors, high efficiency of resource allocation, low resource and environmental cost, and good economic and social benefits, and strive to make each roll of steel contribute the best environmental performance, and promote ecological environmental protection to a new level!
