摘　　要：火力发电厂闭式循环冷却水系统多数是采用钢筋混凝土结构自然通风冷却塔,其噪声污染治理是一个难题。本文以上海吴泾电厂八期1#、2#机组所用特大型双曲线自然通风冷却塔为例,介绍其噪声特性、控制措施及治理效果,可供同类冷却塔噪声控制参考。Thermal-electric power plants closed systems circulate to use the water mostly by adopting the natural ventilated cooling tower, which has a reinforced concrete structure .It's difficulf to manage its noise pollution . Taking the oversize hyperbolic natural ventilated cooling tower used in the 8th periods 1# and 2# machines in Wu Jing Power Station in Shanghai as example ,This paper introduces its noise characteristic , controlling measure and result, which can be provided some advice in the same kind cooling tower for noise controlling.
