0概述不管是活性污泥法还是接触氧化法,曝气充氧是关键的工艺过程。就曝气充氧而言,工艺技术各有千秋,若要保证达到工艺效果,关键在于设备。自从卡鲁塞尔氧化沟问世以来,倒伞曝气机也随之面世,该设备从国外传到我国也有近40年的历史了。时至今日,美国、德国、荷兰和新加坡等 0 Overview Aeration oxygenation is the key process regardless of activated sludge or contact oxidation. In aeration oxygenation, the technology has its advantages and disadvantages, to ensure that the process effect, the key is the equipment. Since the advent of the Carrousel oxidation ditch, inverted umbrella aerator has also come out, the device passed from abroad to China has nearly 40 years of history. Today, the United States, Germany, the Netherlands and Singapore
