摘要
介绍了浙能长兴电厂3万t/d城市中水综合利用工程的项目背景、可行性分析过程及处理工艺,结合系统的实际运行情况分析了项目的效益、处理效果。实践表明,采用曝气生物流化池(ABFT)工艺处理含低浓度氨氮的城市中水,脱氮效果良好,同时可去除部分COD。城市中水经深度脱氮处理后回用作电厂循环冷却水补水是可行的。
The background,feasibility analysis process and treatment technology of the 30 000 t/d multi-purpose project of urban recycled water at Zheneng Changxing Power Plant are introduced.Based on the actual running situation of the system,the project benefit and treatment effect are analyzed.The practice shows that the aeration biological fluidized tank（ABFT） technology is suitable for the advanced treatment of urban recycled water containing low NH3-N and part of COD can be removed.It is feasible that the urban recycled water can be reused as circulating cooling water,after it has been subjected to the advanced denitrogenation treatment.
