Abstract: The necessities and significances of urban reclaimed prehensive reuse are analyzed, and also the technical core of deeply treating urban reclaimed water with aerated biological fluidized tank (ABFT) is expatiated. As the technical parameters, HRT (), designed average NH3-N load ( kgNH3-N/(m3·d)), are achieved, the concentration of NH3-N in effluent is lower than mg/L steadily, and its average removal rate is as high as 95%. Meanwhile, prehensive utilization demonstration project of treating 30,000m3/d urban reclaimed water has been built.
Key words: ABFT; reclaimed water; deep denitrogenation; project demonstration
我国属于水资源贫弱国,长期以来水源污染未得到有效控制,水资源问题已经成为我国
经济可持续发展的制约因素。研究污水的再生和利用尤其是城市中水(本文中城市中水是指经二级城市污水厂处理的达标排放水)综合利用是环境保护、水污染防治的关键环节。
