摘　　要：污水处理厂出水经曝气生物滤池和过滤处理后回用作电厂冷却水和园林绿化用水。结果表明,曝气生物滤池和过滤的方法能有效去除污水中的有机物、NH3-N和SS等。处理出水能够达到《再生水用作冷却用水的水质标准》中的循环冷却水标准《、城市杂用水标准》中的园林绿化用水标准,从而节省了大量的自来水,产生了良好的经济效益和环境效益。The effluent from a sewage treatment plant was treated by aeration biological filter and general filter, and then used as cooling water for power plant and irrigation for afforestation. It was showed that aeration biological filter and general filter could effectively remove organics,NH3-N and SS in sewage. The effluent treated could reach the standard of cyclic cooling water of＂Water Quality Standard of Reuse Water Used as Cooling Water＂, thus saving a great deal of tap water and resulting in better economic and environmental benefits.
