机械加速澄清池由于净水效果好、药耗低、操作方便、对原水水质水量变化适应强等优点,而广泛用于大、中水厂。但是它的搅拌提升设备(特别是大型池子)结构复杂、加工困难、安装不便。因此影响大型池的广泛应用。1977年我们为某厂设计直径为50米的机械加速澄清池处理长江水。单池处理量为1.7米~3/秒。叶轮直径12米、宽1米,提升量为5 Q,叶轮线速度1米/秒,转速1.5转/分。如果按目前普遍采用的
Mechanical accelerated clarifiers are widely used in large and medium-sized water plants due to the advantages of good water purification, low drug consumption, convenient operation, and adaptability to raw water quality and water quantity changes. However, its stirring and lifting equipment (especially large tanks) has a complicated structure, is difficult to process, and is inconvenient to install. This affects the widespread use of large pools. In 1977, we designed a mechanical accelerated clarifier with a diameter of 50 meters for a plant to treat the Yangtze River water. The single-cell throughput is 1.7 meters to 3/second. The impeller has a diameter of 12 meters and a width of 1 meter. The lifting amount is 5 Q, the impeller linear velocity is 1 meter/second, and the rotational speed is 1.5 revolutions per minute. If it is commonly used
