摘要
倒伞型表曝机作为卡鲁塞尔氧化沟的专用设备,其选型设计至关重要。介绍了倒伞型表曝机在选型设计时的关键因素,如表曝机的安装数量及其在氧化沟中的布置和驱动模式、表曝机的叶轮直径与氧化沟的沟宽和沟深的匹配、表曝机的功率与需氧量及曝气池容积的关系、表曝机的安装中心与氧化沟中间隔墙的关系等,指出只有正确的选型设计才能使倒伞型表曝机发挥其优势功能,达到预期的设计效果。
The inverted umbrella surface aerator is a kind of special equipment for Carrousel oxidation ditch, and the selection design is very important. The key factors in its selection design were introduced, such as the installation amount of the aerators, their location and actuated mode in the oxidation ditch, the matching between impeller diameter and dimension of the oxidation ditch, the relation of aerator power to oxygen demand and volume of aeration tank, the relation of installation center to partitions, and so on. It is pointed out that only the correct design can make the inverted umbrella surface aerator work better, and achieve the anticipated effect.
