A Study On The Life Cycle Assessment For Water Environmental System In Circular Industrial Economic Park

As a new environment impact assessment method system, Life Cycle Assessment can be applied to the whole life of water environmental system in circular industrial economic park. Consider the resource consumption, energy consumption and environment impact in all stages of water environmental system in circular industrial economic park, from the exploitation of natural resource and the acquision of raw materials to construction, treatment and the disposal. use the quantitative analysis and qualitative evaluation. At the base of that we can make the improvement evaluation, this method can well integratedly evaluate water environmental system in circular industrial economic park and optimize system designRecently, the assessment of water environmental system in circular industrial economic park is mostly traditional technology economical and environmental impact assessment method, it is very difficult to get the comprehensive evaluation and demonstration of the technics in the whole life cycle.The paper put forward a LCA model of water environmental system in circular industrial economic park based on the technique transit and study status quo and conceived the LCA system of water environmental system in circular industrial economic park.On the grounding of study goal and seoping and the attainability and reality of datas, the paper put the life cyele of water environmental system in circular industrial economic park to three stages, eluding construct, performance and backout.In environment impact assessment, the paper considered four systems of global warming, acidificed atmosphere, eutrophication and hydrophily toxicits to consider the global, region and local environment impact.We can get the environment impact potential of different types and the whole potential by classifying, characterizing and quantifying the inventory data. Then identify the contribution of one environment impact type indifferent stage.Apply environment load method in the environment quantification and analytic hiberarchy process in the model analysis.In order to reflect the practice more effectively, quantitative analysis and qualitative evaluate method are both used.According to two planning and design programs of water environmental system for life cycle assessment comparison in Shang (Zhou) Dan (Feng) circular industrial economic park.The life-cycle assessment would be usede to select the plan to achieve the greatest potential resource,energy reduction and waste prevention. Eventually, the measure and recommendations to reduce and eliminate some impact would be proposed, which provide evidence for optimizing water environmental system.
