摘　　要：为了解决某新兴城区水资源短缺,实现可持续发展,通过调查研究确定了以市政回用和工业回用为目的的再生水需求及组成,并构建了以混凝/沉淀工艺和臭氧/气浮工艺为核心的两组并联再生水处理系统。通过对两组不同工艺的出水水质进行分析,可知两组工艺的处理出水水质均达到回用水质要求,并且臭氧/气浮工艺对氨氮、铁、锰、大肠杆菌等的去除效果明显优于混凝/沉淀工艺。因此,臭氧/气浮工艺可以更好地实现缺水地区再生水多元化利用和系统优化配置,解决城市水资源短缺的问题。In order to solve the shortage of water resources and realize sustainable development ina new urban area, the reclaimed water demand and composition for municipal reuse and industrial reuse were determined. Two reclaimed water treatment systems using coagulation/sedimentation process and ozonation/floatation process were constructed. While the effluent quality of both processes all met reuse water quality requirements, the ozonation/floatation process was superior to the coagulation/sedimentation process in removal of NH3 - N, iron, manganese ion and coliform bacteria. Therefore, the ozonation/ floatation process could better achieve reclaimed water diversified utilization and system optimization configuration in water shortage areas, thus relieving the shortage of urban water resources.
