Industrial wastewater reuse is a major measure to mitigate the depletion of available freshwater resources in the catchments around industrial areas and to prevent possible future water shortages and the resulting problems for industry, economy and society. Combining a set of environmental aspects and economic aspects of different wastewater treatment technologies, the authors developed a model-based approach for planning and evaluating water reuse concepts in industrial parks. This paper is based on an exemplary Model Industrial Park. The results based on data primarily calculated for Germany show that, for the majority of the indicators, the installation of the Water Reuse Plant seems to be beneficial for all examined reuse options. Considering the economic dimension, due to economies of scale, reuse options with larger volumes of treated water are preferable since the costs per m3 of reuse water are reduced by up to 33%. On the other hand, the environmentally preferable option depends on the respective indicator, e.g. for freshwater eutrophication, the higher the reuse factor, the lower the impact, leading to reductions between 8 and 12%. For climate change, the best option is dependent on the reuse purpose leading to reductions between 8 and 52%.

工业园区中水回用的经济和环境评估:基于模型工业园区的案例研究

工业废水回用是减轻工业区集水区可用淡水资源消耗并防止未来可能出现的水资源短缺以及由此给工业,经济和社会带来的问题的一项主要措施。结合了不同废水处理技术的一系列环境因素和经济因素,作者开发了一种基于模型的方法来规划和评估工业园区的水回用概念。本文基于示例性示范工业园区。根据主要针对德国计算的数据得出的结果表明,对于大多数指标而言,安装水回用厂似乎对所有经过检验的回用方案都有利。考虑到经济规模,由于规模经济,3个回用水减少了33%。另一方面,对环境更有利的选择取决于相应的指标,例如,对于淡水富营养化而言,回用系数越高,影响越小,导致减少8%至12%。对于气候变化,最佳选择取决于再利用目的,从而减少8%至52%。
