Change the mode of economic development Gansu circular economy planning to expand the value-added space

Business news on February 2: global energy crisis, climate abnormality, environmental pollution and other issues extend the big proposition of economic development mode and human survival Energy conservation and emission reduction, circular economy and transformation of economic development mode are common choices made by China and even the world In this context, Gansu's circular economy has also been given a strong impetus and fresh connotation "Biogas residue - fish farming, pond mud - fertilizer, coal dust, coal gangue and other industrial wastes - new building materials, cracking flue gas from oil refining - thermal energy..." In the blueprint drawn in the general plan of circular economy in Gansu Province, each line connects every link from resources to products to renewable resources, and finally becomes a closed loop This is not a geometric problem, but an economic equation Each consumption terminal can be the starting point of the next production The waste of one enterprise can also be the raw material of the next Resources are reused and waste becomes treasure The pursuit of the least consumption, the most use and output is the principle of constant circular economy The consumption of resources has been reduced, the industrial chain has been extended, the pollution discharge has been reduced, the ecological environment has been increased, and the unique "increase and decrease method" of circular economy has outlined a bright future for Gansu Only by doing well in the big calculation of circular economy can we solve the big proposition of Gansu's economic development The core of "subtraction" of resource consumption and "addition" of industrial chain circular economy lies in the efficient utilization and recycling of resources The basic principle is reduction, reuse and resource utilization (3R principle) First of all, we should reduce the amount of material input from the source and improve the efficiency of resource utilization ——In the general plan of circular economy in Gansu Province, the image of circular economy is compared with "eating and squeezing" How to "eat" to have a taste, "nickel capital" Jinchang city transformation or can be explained one or two Sulfur dioxide, the industrial waste gas, was the biggest headache for Jinchuan company About 7 tons of sulfur dioxide are produced for each ton of nickel production and 2 tons of sulfur dioxide for each ton of copper production In 2003 and 2004, Jinchang was listed as one of the "top ten air pollution cities in China" because of the excessive sulfur dioxide emission In 2005, Jinchang became one of the seven key environmental protection cities with poor air quality Now, through the development of circular economy, Jinchuan company makes sulfur dioxide gas into sulfuric acid, and sulfuric acid enters Xinwang group and Jinhua Group respectively to produce PVC and sulfur-based fertilizer It reduces emissions and increases economic benefits To understand the circular economy of Jinchang City, you can first look at a process flow chart of Jinchuan company The anode slime and other products of Jinchuan Company are used in the production of sulfur and nickel salt in the nickel Capital Industrial Company The sulfur dioxide produced in the production process is recycled into sulfuric acid and sent to the chemical fertilizer production line of Jinhua Group The fluorine waste gas produced in the processing process is converted into hydrogen fluoride, which is used as auxiliary material Hydrogen fluoride finally returns to Jinchuan company The waste residue in the production process enters the gold mud group for the production of dry process cement Waste water is recycled and recycled in enterprises Through the implementation of circular economy and energy conservation and emission reduction measures At present, 99.75% of the flue gas discharged by Jinchuan company is used to produce acid, and more than 90% of the production water is reused The company's ore recovery rate is over 96%, mining loss rate and dilution rate are controlled below 5%, which has reached the international advanced level The annual reuse of reclaimed water has exceeded 10 million tons, the reuse rate of reclaimed water has reached 86%, and the treatment rate of industrial sewage has reached 100% Downstream pollution control is a way, and upstream reduction is a better way In this way, the seriously polluted "waste" has become a treasure and a renewable resource The process of waste reuse and recycling is also the process of lengthening the industrial chain In the recycling of resources, Sichuan new hope group has joined in, Guizhou Hongfu company has joined in, China chemical fertilizer company, Inner Mongolia Taixi Coal Group and other domestic well-known enterprises have participated in Jinchang circular economy industrial circle Some seemingly unrelated enterprises, because this "addition problem" is linked together The deep processing links of products are important links, connecting the intensive development of upstream and downstream industries and the large-scale development of related industries Some of these chains are based on high technology, others are just based on the idea of "not afraid of trouble" However, the superposition of benefits is brilliant and surprising Gansu has successively established Baiyin, Wuwei, Jiayuguan, Dingxi and other pilot cities, and carried out more in-depth exploration The overall plan of circular economy of Gansu Province also proposes that we should strive to build 16 industrial chains of circular economy, focus on cultivating 100 key enterprises, transform and upgrade 36 development zones above the provincial level, and form seven bases of circular economy including Jinchang This is precisely the joint point of the circular economy and the great thinking and planning The development of circular economy in our province will be carried out in an all-round way The basic characteristics of "subtraction" of pollution emission and "addition" of ecological environment circular economy are low consumption, low emission and high efficiency In essence, they are innovative economic development models in line with the concept of sustainable development The development of circular economy is the internal requirement for the implementation of the scientific outlook on development and the only way to build a resource-saving and environment-friendly society ——According to the general plan of circular economy in Gansu Province, "no coal is found in coal mining, no ash is found in power generation, green mountains and green water circulation." This is the most impressive thing about Huating, the "coal capital" But according to laohuating people, Huating used to be different Because of the coal dust pollution, Huating was once called "black city" It was grey when the sky was fine and muddy when it rained People said that the sparrows flying out of Huating were black The former "black city" has become green again, which is the benefit of energy conservation and emission reduction, and the development of circular economy In Huating, Dongxia coal mine sewage treatment line, black and red sewage, after numerous processes, is colorless and transparent, and then enters the mine for recycling The newly built Chenjiagou coal washing and preparation plant has eliminated the traditional simple classification and screening system, and made use of the advanced washing and preparation technology at home and abroad From the underground coal output to the coal washing and preparation plant, there is no coal slag on the ground; the underground water washing water is closed-circuit circulating, and the coal slurry water is not discharged outside, so as to realize zero pollution discharge of waste water The new Huating power plant is a typical clean energy enterprise Water saving unit, air cooling and slag are good materials for casting concrete in construction site The ash is also favored by cement plant There are no tall chimneys and rolling smoke here, just like the woven lawn and blue water and blue sky Huating's road of resource conservation and environmental friendliness is also the road of Gansu's circular economy development Our province is a province with large resources, extensive utilization of resources and serious environmental pollution Resources and ecology are the basis of human survival and development Any reason for development at the expense of resources and ecology will be far fetched In front of the already extremely fragile ecology, Gansu urgently needs a transformation from cocoon to butterfly Based on this understanding, our province has already begun to vigorously promote the work of circular economy In 2007, the first explosion of Longyuan was heard in Yongchang Power Plant Since then, Gansu has begun to phase out enterprises and production lines with low technology level, backward technology, waste of resources and environmental pollution on a large scale In 2008, nine major polluters in the province, including power, steel, iron making, ferroalloy, calcium carbide, cement, paper, coke and alcohol, eliminated 3.75 million tons of backward production capacity and 259000 kilowatts of electric power, 89 of which were "kicked out" Through the development of circular economy, our province has completed the goal of energy conservation and emission reduction for four consecutive years, and improved the industrial level and the quality of economic growth in Gansu Province In 2009, compared with 2007, the province's resource output rate increased by 9.8%, the comprehensive utilization rate of industrial solid waste increased by 24.8%, the energy consumption of RMB 10000 GDP decreased by 9.6%, and the water consumption of RMB 10000 industrial added value decreased by 22.3% Of course, the role of circular economy in ecological restoration and environmental protection is not only here In the perspective of circular economy, the construction of new energy in our province has also attracted much attention Thousands of miles of Hexi, unlimited scenery, "green energy" in our province at the beginning of brilliant The overall plan of circular economy of Gansu province puts the advantages of clean energy such as wind energy and solar energy into full play, builds the "Three Gorges on land" as an important starting point for the development of circular economy and realizes the docking with high energy consumption industries such as nonferrous metals and metallurgy in Gansu Province, forming a regional resource comprehensive development and utilization mode of "new energy high energy industry downstream products" Backward and polluted enterprises need to be eliminated, dismounted and out of business; new industrial industries need to be invested, launched and rooted With the implementation of the overall plan of circular economy in Gansu Province, Gansu needs to be brave enough to cut through the thorns on the road of circular economy All of these are for a simple and beautiful promise - let people drink clean water, breathe clean air, eat safe food, and live in a good environment All of this will not be a dream any more, but will become a happy journey for human beings to return to nature and enjoy life To enhance the competitiveness of enterprises, change the mode of economic development, and cultivate new economic growth poles is a bigger "additive" development of circular economy, an inevitable choice to change the mode of economic development and achieve sound and rapid development General Secretary Hu Jintao clearly pointed out that "we should turn the pressure of the international financial crisis on the formation of economic restructuring into power, change challenges into power, change challenges into opportunities, increase the intensity of industrial restructuring, vigorously develop circular economy, and strive to form new economic growth points and new competitive advantages." ——According to the general plan of circular economy in Gansu Province, someone has made a calculation for the energy conservation and emission reduction target promised by China, which means that China needs to invest 30 billion dollars annually for this purpose in the next 10 years In the early stage of circular economy construction, there may be many energy-saving projects, many pollution projects, many links to increase, a lot of investment, and a lot of cost But for the underdeveloped and heavily polluted resource-based province like Gansu, the difficulty is imaginable However, circular economy is the transformation that Gansu has to realize immediately According to the 2002 China sustainable development strategy report issued by the Chinese Academy of Sciences, if the global average comprehensive development cost is 1.00, the Chinese average comprehensive development cost is 1.25 That is to say, we need to pay 0.25 yuan more for the goods that people can buy for 1 yuan For Gansu, the development cost is higher In 2008, the energy consumption of RMB 10000 GDP in our province was up to 2.01 tons of standard coal, nearly double the national average level, and the energy consumption of RMB 10000 industrial added value was up to 4.2 tons, 1.57 times the national average level High cost and low output mean low profit space and small development space In the face of the coming international financial crisis, some enterprises with high consumption, low output and low added value are the first victims This makes us more aware that it is imperative and imminent to change the mode of economic development and expand the value-added space Gansu
