Huolinguole walks out of the pollution mud: the aluminum pollution control technology is leading, and the grassland reappears blue sky and white clouds

in the past, thick smoke billowed and dust everywhere, but now the blue sky and white clouds, beautiful mountains and clear waters... Huolinguole City, a heavily polluted city in Inner Mongolia autonomous region that has been concerned by domestic and foreign media, takes the aluminum pollution control as a breakthrough, explores international advanced pollution control methods, and promotes the fundamental improvement of the environment in the whole region

advanced technology, the lowest pollution emission in the country

a city was built and prospered because of coal. For many years, huolingole City, under the jurisdiction of Tongliao City, Inner Mongolia, has taken measures according to local conditions, and has developed an industrial path of coal power generation, aluminum smelting and aluminum post-processing. It is considered by industry experts to be the ideal coal electricity aluminum integrated industrial base of Zui in China. It has formed 33.25 million tons of coal, 4.42 million kw of power installation, 1.77 million tons of raw aluminum and 1.61 million tons of aluminum post-processing capacity. However, dust, fluoride and sulfur dioxide are produced in the process of aluminum electrolysis, and the surrounding grassland ecological environment is polluted. A large number of cattle, sheep and other livestock are sick and die, which makes the local people miserable

"in June 2016, the central environmental protection supervisor put forward severe criticism, prompting an environmental governance storm in the Huolin River." Li Jiexiang, Secretary of Tongliao municipal Party committee, said that the government urged enterprises to achieve ultra-low emissions on the basis of the original environmental protection standard emissions. At the end of 2016, Inner Mongolia HuoMei Hongjun aluminum power company, a coal, electricity and aluminum integrated enterprise, was the first to "eat crabs"

there are no demonstration cases in the industry "In order to meet the cycle time required by customers, how to do the ultra-low emission project? The technical backbone of the company formed a research team and repeatedly studied and demonstrated. Zui finally decided to adopt the limestone gypsum wet flue gas purification technology. Hui Jingming, the deputy general manager of the company, said that this technology was used in the production of electrolytic aluminum for the first time. At the end of 2017, all four units were in stable operation, which was the first ultra-low emission unit in China.

today's Hongjun company plant Clean and tidy, flowers and plants everywhere. Hui Jingming introduced that the national emission standards for particulate matter ≤ 20mg/Nm3, sulfur dioxide ≤ 200mg/Nm3, fluoride ≤ 3mg/Nm3, and the actual emission indicators for particulate matter are less than 5mg/Nm3, sulfur dioxide is less than 35mg/Nm3, and fluoride is less than 0.3mg/Nm3. The emissions of the three indicators are all the lowest in the country

two other major aluminum companies, Inner Mongolia Jinlian Aluminum Co., Ltd. and Inner Mongolia Chuangyuan Metal Co., Ltd., also successively implemented ultra-low emission projects last year. At the beginning of July this year, 11 industry experts including Zhang Wenhai, academician of the Chinese Academy of engineering, appraised the cleaning of equipment on site. When consulting the universal experimental machine, our customers believed that on the basis of electrolytic flue gas dry defluorination, limestone gypsum wet desulfurization and defluorination collaborative purification technology was adopted for the first time, which was applied to the purification of low concentration sulfur dioxide flue gas and aluminum electrolytic flue gas, and the emission index was significantly better than the national emission standard of pollutants in the aluminum industry, This achievement has been industrialized in three enterprises

environmental protection as an advantage enterprises taste the sweetness

"either be eliminated in environmental protection supervision, or use scientific and technological innovation to find a way to turn environmental protection into a competitive advantage of enterprises!" Zhanghongfu, Secretary of the Huolinguole municipal Party committee, said that enterprises implemented emission reduction according to the high standard of Zui, which increased investment and cost, but also tasted the sweetness

"the four sets of devices invested 310million yuan, and no one was sure about the results. I didn't expect that the effect after Zui was better than expected." Cao Guanghua, Secretary of the Party committee of Hongjun company, laughed, "the cost per ton of aluminum has increased by more than 90 yuan, but protecting grassland ecology is what central enterprises must perform. It can play a demonstration role for other enterprises. This money is worth it!"

Jinlian company invested 249million yuan in two sets of ultra-low emission devices, and the cost per ton of aluminum increased by about 70 yuan. "In the short term, the input cost has indeed increased, but as the state has higher and higher requirements for enterprise environmental protection, for enterprises, whoever takes this step first will be in the forefront of the industry." Gaoheng, general manager of Jinlian company, said

Chuangyuan company, which integrates solar energy, coal power, aluminum and aluminum processing, installed ultra-low emission devices during construction, and the cost per ton of aluminum was only increased by about 40 yuan. Caoyong, the general manager of the company, told that the ultra-low emission standard is high and the pollution is small. It will be implemented synchronously during construction, and the cost increase is not high

Cao Guanghua said that since this year, electrolytic aluminum enterprises in Shanxi, Yunnan and other places have come to Hongjun company to "learn lessons" and learn ultra-low emission treatment technology. "Enterprises' awareness of environmental protection is generally improved, and we hope to provide the industry with ultra-low emission technology experience."

global environmental governance, green mountains and green waters reappear

Naren Baoli gaogacha, zarut banner. The aluminum plant near Zui is less than 10 kilometers away, once seriously polluted, and has been relocated since 2013. Herdsman hasbater said that when he was a child, grass could grow waist high, but he didn't even have his ankles a few years ago, and livestock were often sick

since 2016, the city of horingol has carried out intensive pollution control since its establishment. The city has invested 470million yuan in ultra-low emissions alone, and more than 1 billion yuan in closed storage and transportation of coal. The ecological environment is reversing

there are 11 coal mines in horingol, of which 8 are open-pit mines. Since 2017, Huolinguole has required coal related enterprises to "store coal without seeing coal, transport coal without exposing coal, and produce coal without loose burning". The city's 14 thermal power units will complete the ultra-low emission transformation by the end of 2019

implement the policy of "who manages, who invests, who benefits", and manage 100000 mu of land damaged by mining in the city by stages and in batches; To control desertification and exposed mountains, more than 12000 mu of farmland has been returned to grassland since last year; More than 8700 households have been renovated, and central heating will be implemented by the end of this year; In the past three years, the green area of the city has increased by 3990 mu, and the green space rate has reached 42%; In 2016, Tongliao Environmental Protection Bureau commissioned a third-party organization to monitor the results. The results showed that after the three electrolytic aluminum enterprises were put into operation with ultra-low emissions, based on the electrolytic aluminum production capacity of 1.77 million tons, 640 tons of dust, 350 tons of fluoride and 21000 tons of sulfur dioxide could be reduced every year. The monitoring of horingol meteorological station shows that in the past 45 years, the average annual sand and dust days were 15.6, while in the past three years, it was only 5.1 days

hasbartel said that now, the grassland has slowly changed back to what he remembered
