碳碱法制取硼砂技术演变中资源消耗与环境影响

Resource Depletion and Environmental Impact in Evolution of Alkali Carbonate Process for Borax Preparation

采用工业生态学矩阵系统评价方法研究了碳碱法制取硼砂技术演变过程资源消耗及环境影响状况.对矩阵评价方法的计算模型进行了修正及完善,并勾勒出相应的因子(阶段)-环境效应图例.结果表明,以碳碱法制取硼砂过程的技术策略在工厂整体运行过程中达到了一定程度上的环境协调、友好.由此,积极建设和完善以工厂整体运行过程为主体路线的硼砂工业生态园,从而为后期行业环境规划提供相应的技术建构与潜在发展空间.

Through the IE （industrial ecology） matrix system evaluation method resources depletion and environmental impact in the evolution of alkali carbonate process for borax preparation were studied with the relevant calculation model improved and relationship between factor（stage）and environmental effect plotted. The results showed that a chemical plant is as a whole running in an environmentally friendly way to a certain extent if taking the alkali carbonate process as its technologic strategy to prepare borax. It follows that there will be a better technologic framework with a potential room for further development in the later-period industrial environment planning to actively build and perfect an eco-industrial park for borax industry, where all plants will be running in such a way.
