The pilot project of circular economy in Hebi City focuses on the use of resources by lengthening the industrial chain, promoting the convergence of industries, developing new products based on waste, and innovating production processes. At present, a circular economy industrial chain such as coal electricity materials, food industry, and magnesium metal has been initially formed.
For the coal-fired chemical industry, it will focus on the development of the cyclic industrial chain of coal-to-electricity, coal chemical, and coal-fired waste utilization. The 2×135,000 kilowatt comprehensive utilization thermal power plant constructed can consume 700,000 tons of coal slime and inferior quality coal, and the 210,000 tons of ash produced can be made into ceramsite sand and blocks, which can reduce the ash field to 300 acres; The power plant replaces the original 46 small boilers in the new district to provide heat, saves 150,000 tons of standard coal, and reduces more than 400 tons of sulfur dioxide. The 10 large coal gangue fired bricks and fly ash products projects that were constructed will consume 1.65 million tons of coal gangue and fly ash, which will not only consume more coal gangue in the year, but also consume 500,000 tons of coal gangue piled up in previous years. . The planned 22 gas-fired generating units have been completed with 16 units. After the completion of the project, 23.38 million cubic meters of gas can be used annually, generating 66 million kWh of electricity, making 90% of the city's coal bed methane comprehensively utilized. The completed mine water comprehensive utilization project will enable the coal mine water of the Hefei coal mines to be fully processed, and basically meet the needs of the third phase of the power plant and the cooling water of the Hefei integrated thermal power plant. Tongli Cement uses fly ash as a new dry process cement admixture, and consumes 500,000 tons of fly ash and waste residue annually. The built-in waste heat power generation project can meet about 40% of its own electricity consumption.
In the food processing industry, there are 19 organic fertilizer plants, two large-scale biogas stations, and seven biogas power stations built around the comprehensive utilization of wastes such as feces and scraps from the livestock husbandry and food processing industries. Biogas power generation is under construction. There are 8 stations, with an annual output of 400,000 tons of organic fertilizer, 12 million cubic meters of biogas, and an annual output of 22 million kWh. The city's large-scale livestock and poultry breeding enterprises have completed the "harmless and resource utilization" project, in which Daiyou Company uses chicken blood to produce blood-derived bioactive protein projects, and comprehensively uses 10,000 tons of chicken blood to digest the surrounding 150 kilometers range. Chicken blood produced within the slaughter production line. A biomass power plant that consumes 200,000 tons of straw each year has been built around the use of planted waste, and Nuomeimei Biological Products, Taixin Straw Science and Technology, and Hang Lung State have used straw to extract sugar and xylo-oligosaccharides or to produce new organic fertilizers. The company has also been built or partially completed. By the end of last year, the comprehensive utilization rate of agricultural waste in our city reached 90%.
In the magnesium metal industry, 62 small metal magnesium plants with an annual output of 1,000 tons or less were shut down, and about 1.1 million tons of carbon dioxide, more than 8,000 tons of coal dust, and more than 6,000 tons of sulfur dioxide were reduced annually. Through the introduction of funds, integration of resources, improved technology, the development of deep-processed products, to create metal magnesium - high-purity magnesium - magnesium alloy - magnesium alloy die castings - magnesium alloy profiles and plates and a variety of special product industry chain. Weienke uses the new coal-water slurry smelting method and regenerative reduction furnace technology to reform traditional processes for the smelting of magnesium metal companies, which will increase the comprehensive utilization of energy by more than twice, save energy by more than 50%, and reduce energy consumption and environmental protection to domestic levels. Advanced level. Henan Dongda High-temperature Energy-saving Materials Co., Ltd. uses magnesium slag and gangue wastes from the smelting of magnesium metal to produce high-performance new-type ceramic filter media. Annual recycling of metal magnesium smelting waste residue and coal gangue wastes is 100,000 tons, making magnesium metal The industrial cycle chain has been further improved.
Vigorously promote circular economy, make our city more blue, clear water and fresh air. In 2009, the chemical oxygen demand and sulfur dioxide reduction in Hebi City exceeded the target of “Eleventh Five-Year Plan†and the city’s drinking water source The water quality compliance rate is 100%, and the urban air quality is 92.6%, both of which are the highest in history.
Hebi industrial solid waste utilization rate reached
Yesterday, the reporter learned from the city circulation office that there were 15 circular economy projects completed in Hebi City last year. At this point, 77 key circular economy projects that have been planned and implemented since the Hebi City pilot project have been completed and put into operation, yielding good economic, environmental, and social benefits. According to the latest data, the comprehensive utilization rate of industrial solid waste in our city reached 91% last year, which is nearly 25 percentage points higher than the national average.
