蒙西生态工业园区循环工业体系-物质、能量循环

MENGXI ECO-INDUSTRIAL PARK LOOP INDUSTRIAL SYSTEM-MATERIALS,ENERGY RECYCLING

日益严峻的环境与资源问题直接威胁到了人类的生存,为了实现全社会的可持续发展,人们提出了循环经济理论,以解决人类面临的一系列环境与生态问题循环经济是一种先进的可持续发展模式,而生态工业园区是实现循环经济的重要载体。在园区内,通过清洁生产以及生态产业链的衔接,可以充分地利用现有资源,达到废弃物排放最小化和环境污染最小化的目的。物质能量循环是生态工业园区的核心部分,在本文中采用物质利用强IU的研究方法对蒙西生态工业园区的物质循环进行了分析。园区内的主要产业为:电厂,水泥厂,捣固焦厂和高岭土厂。通过对其固体废弃物、新鲜用水和污水的IU值计算,得出分别为29.7t/104RMB,24.6m3/104RMB,4.4 m3/104RMB。同时通过对蒙西工业园区主要产业进行能量投入产出分析,得出其单位GDP能耗分别为11.1t标准煤/104RMB、10.6t标准煤/104RMB、0.5t标准煤/104RMB、4.1t标准煤/104RMB。从而得出园区内IU值偏大,物质的循环利用程度较低;又通过比较得出园区内主要企业能耗均符合国家标准,但在园区内部能量循环不够完善,亟待加强。

The increasingly serious environmental and resource issues a direct threat to the survival of mankind,in order to achieve the sustainable development of society as a whole,it is proposed the theory of circular economy in order to solve humanity faces a series of environmental and ecological problems of circular economy is an advanced and sustainable development model,while the eco-industrial park is an important carrier to achieve circular economy.In the park,through cleaner production and eco-industrial chain link,you can fully utilize existing resources to achieve discharge of waste minimization and pollution minimization purposes.Material and energy cycle is a core part of eco-industrial park,in this paper the use of substances by high-IU research methods Mengxi eco-industrial park on the circulation of materials analyzed.The park＇s major industries are： power plants,cement factories,tamping coke plant and kaolin plants.Through its solid waste,fresh water and sewage IU value calculations,respectively 29.7t/10^4RMB,24.6m^3 / 104RMB,4.4 m^3 / 104 RMB.At the same time through the West Inner Mongolia Industrial Park,the major industries to the energy input-output analysis,obtained the unit GDP energy consumption,respectively 11.1t coal / 10^4RMB,10.6t of standard coal / 10^4RMB,0.5t standard coal / 10^4RMB,4.1t of coal / 10^4RMB.IU value of the park so as to arrive too large,low level of material recycling;also obtained by comparing the energy consumption of major companies in the park are in line with national standards,internal energy circulation in the park,but not perfect in urgent need of strengthening.
