化工园区循环经济发展的规划构建

Construction and planning of circular economy for Chemical Industry Park

随着国家对化工行业环境保护和生态建设方面的要求越来越高,化工园区作为化工行业的聚集地和发展趋势,响应国家政策构建循环经济是当务之急。循环经济利用再循环技术和废弃物资源化技术,贯彻"减量化、再使用、再循环"的"3R原则",降低有毒有害物质向环境的排放;同时构建循环经济能够促使化工园区挖掘资源潜力,提高资源利用率,使得资源的价值能够进一步体现。本文通过分析化工园区的产业链特征,并针对性地提出了化工园区构建循环经济的两方面工作:在原有产业链的基础上构建循环经济产业链以及完善服务系统。在构建循环经济产业链的过程中不仅要考虑工业代谢分析获得的产业接口,还结合产业链风险评估提出要引入增柔企业以控制产业链风险。在循环经济服务系统中特别提出建立循环经济信息平台,以打破地理限制扩展循环产业链。

Along with the improvement of Chinese environment requirements of chemical industry,Chemical Industry Park,concentrative areas of chemical industry,should develop circular economy as soon as possible. Following the ＂3R principle＂,＂reduce,reuse,recycle＂,circular economy employing recycling technology and waste resource utilization technology must reduce the pollutant and toxic emission. Beside,developing circular economy will urge Chemical Industry Park to develop potential of resources,promote value and increase utilize of fossil resources. The characteristic of industry chain is analyzed and two parts of developing circular economic for Chemical Industry Park are given. One is to fabricate circular economic industry chain based on the original industry chain and the other is to optimize the service system. During the construction of circular economy industry chain,an industrial metabolism analysis should be employed to determine the interface of industry,and risk evaluation technique should be used to control industry chain risk by importing. Establishing circular economic information platform for Chemical Industry Park to extend circular industry chain without geographical limitation should be especially emphasized in the service system.
