摘要
水资源严重短缺已经成为制约我国经济社会可持续发展的瓶颈,再生水回用于农业是污水资源化的有效途径。在分析再生水利用现状的基础上,建立了再生水灌溉优化模型,利用优化模型分析了用水组成、再生水质及农作物组成的相关指标。最后,以郑州市为例,对再生水农业回用进行了技术经济分析。
Water shortage is a bottleneck which constrains China＇s economic and social sustainable development.Urban wasterwater reused for agriculture is an effective way to turn wastewater into available water resources.Based on an analysis of utilization status of reclaimed water,this paper firstly does research on the optimization model of reclaimed water irrigation.Then,relevant indicators which determine the composition of water,recycled water quality and composition of crops,are analyzed.Taking Zhengzhou City as an example,a technical and economic analysis is made of reclaimed water irrigation.
