孔管增氧技术也称“纳米管”或“曝气管”增氧技术,它采用罗茨鼓风机将空气送入输气管道,输气管道将空气送入微孔曝气管。由于其孔径小,可产生大量微细化气泡从管壁冒出分散到水中,而且上升速度缓慢,气泡在水中移动行程长,与水体 Hole tube aerobic technology, also known as “nanotube ” or “aeration tube ” aerobic technology, which uses the Roots blower to send air into the gas pipeline, gas pipeline into the microporous aeration pipe . Because of its small aperture, can produce a large number of fine bubbles from the pipe wall to disperse into the water, and the slow rate of increase, the bubbles in the water to move long trip, and the water body
