Longbai Group: Be a leader in green ecological development

In early autumn, the sky is high and cloudy. Walking into the artificial cooling wetland of Longbai Group, with a panoramic view of green water and flowers, and low-flying egrets playing in groups, the wetland has quietly become a habitat for wild animals. To the south of the wetland, is the group titanium dioxide factory area, workshop machines "singing", production in full swing. Wetlands and chemical parks are in the same frame, just like a beautiful picture of harmonious symbiosis between man and nature, industry and ecology.

August 15 is the first National Ecological Day. Longbai Group's long-term green ecological development strategy has also ushered in a bumper harvest season in this autumn.

As a leading enterprise in China's titanium industry, Longbai Group always adheres to the development concept that "to protect the ecological environment is to protect the productive forces, and to improve the ecological environment is to develop the productive forces", pay attention to energy saving and environmental protection, strengthen the tackling of green design technology, and persist in innovative science and technology to promote the low-carbon, environmental protection and green development of enterprises. The construction of a green closed-loop system from park design, raw material procurement, production technology, product development, marketing mode and three waste recycling has led to a new way of green ecological and high-quality development.

Make continuous efforts to implement the concept of green development and achieve results

The construction of ecological civilization is a profound change involving production, life style and values.

The chairman of Longbai Group and Benliu introduced that after entering the 14th five-year Plan, Longbai Group took environmental protection work as its primary task, set new national environmental standards and requirements, applied new technologies and new technologies, and invested a total of 734 million yuan. 46 environmental protection technical renovation projects have been completed, such as in-depth treatment of tail gas from sulphuric acid production, ultra-low emission treatment of boiler tail gas, reuse of by-product energy from furnace gas, standard raising treatment of calcination tail gas, treatment of chlorination refined tail gas, etc. Under the premise of continuous expansion of production capacity, the emission of pollutants per ton of products has been reduced year by year. Through the application of key green and low-carbon cycle technologies, such as the improvement of motor energy efficiency and waste heat reuse, the comprehensive energy consumption per unit of the company's main products, sulfuric acid titanium dioxide and chlorinated titanium dioxide, has been reduced by 15% and 25% respectively compared with the end of the 13th five-year Plan. Effectively promote the green development of enterprises.

Dare to innovate and open up a new path for the treatment of titanium gypsum

Titanium gypsum produced in the production of titanium dioxide by sulfuric acid process is generally treated by storage, which is not conducive to the comprehensive utilization of waste resources in titanium dioxide industry.

Chen Jian, vice president of research and development of Longbai Group, said that Longbai Group adheres to the concept of "treating waste, turning waste into treasure, recycling and balanced development", vigorously develops and expands the application ways of by-product titanium gypsum, and actively creates a green industrial chain. now it has successfully developed downstream products such as composite concrete, cement retarder and gypsum brick, fully realizing the recycling of titanium gypsum resources. The company also reclaimed the titanium gypsum yard to open up a new way to solve the difficult problems in the industry. The total investment has exceeded 18 million yuan, and the total restoration of green space in Jiaozuo City and Deyang City has exceeded 700mu. It is estimated that the annual economic benefits of reclamation of agriculture and forestry will exceed 1.5 million yuan.

Technology strives to be the leader in ultra-low emissions in the industry.

Longbai Group insists on putting science and technology first, in order to strengthen the whole staff's awareness of environmental protection and comprehensive governance actions, and help to win the defense of blue sky and clear water pure land.

In view of the in-depth treatment of waste gas pollution sources, the use of advanced treatment measures in the industry, the construction of an exclusive atmospheric protection system, high-quality promotion of standard upgrading, and actively promote the improvement of regional environmental quality.

In the treatment of calcined tail gas, it invested 35 million yuan and adopted the latest scientific and technological innovation technology in the industry-- low-temperature plasma deep purification technology, which successfully passed the appraisal of technological innovation achievements in titanium dioxide industry. it has become one of the most innovative scientific research achievements in the titanium dioxide industry.

Different from the traditional waste gas treatment methods, low-temperature plasma technology can achieve ultra-low emission of pollutants without producing waste pairs, so that the emission index of tail gas is much lower than the national standard. The development and application of this technology is in line with the national industrial policy of energy saving, emission reduction and cleaner production, conforms to the development direction of titanium dioxide industry to achieve ultra-low emissions, and plays a good exemplary and leading role in the sustainable development of the industry.

Scientific Planning to build Green and safe Mine

Respecting, conforming to and protecting nature are the fundamental tenets of ecological development.

During the 14th five-year Plan period, Longbai Group persisted in building environmental safety barriers for imprisoned water, constantly upgrading its sewage stations, building pre-treatment facilities for magnesium removal wastewater from circular economy, building biochemical treatment plants, and building an artificial cooling wetland park.

As the "granary" of the titanium industry of Longbai Group, Panzhihua Mine firmly protects the "green" background of the mine, forms a new pattern of three-dimensional green mining development of "point, line and surface", and effectively promotes the coordinated development of the development and utilization of mineral resources and ecological environment protection.

The Niuchangping tailings reservoir of Fengyuan Mining Company is green all over the mountain and the spring water is crystal clear. All this is due to the "decontamination diversion system" set up by the company next to the tailings reservoir. The system invests 11 million yuan to build the separate disposal of leachate and mountain flood to ensure that the leachate of the tailings reservoir is fully reused, and the 24-hour online water quality monitoring system in the plant area is the last hurdle of ecological security.

The concept of "green water and green mountains" has long been integrated into the high-quality development process of Longbai Group, and each case of green environmental protection is a vivid practice of the concept of "creating titanium beauty to be a respected enterprise".

He Benliu said that Longbai Group will continue to take the initiative to shoulder the important task of ecological protection, actively expand the space for green development, continue to paint the background of green development, and make every effort to create an environmentally friendly and resource-saving green Longbai. To enhance the global comprehensive competitiveness of enterprises and lead the green and high-quality development of China's titanium industry.
