0 1,000 N 表面曝气机是利用电机直接带动轴流式叶轮,将废水由导管 经导水板向四周喷出并形成一薄片(或水滴状)的水幕,在 飞行途中和空气接触形成水滴,在落下时撞击液面,液面产 生乱流及大量的气泡,使水中含氧增加.本机系将池底的水 吸上而由上方送出,形成一循环水流,故兼有搅拌的效果, 适用于生活污水,农牧养殖供氧及其他各种工业污水曝气等. The high-speed aerator line is designed to maxi- mize the two most important functions of any aeration device―oxygen transfer and mixing of wastewater . The waste liquid is pumped through the unit in a manner which creates the most optimal spray pattern to facilitate oxygen into the wastewater . At the same time, this pumping action creates a tank velocity pattern which ensures the mixing of contents and thus the oxygen dispersion. Years of experience in the design and application of mechanical aeration equipment, combined with the full capabilities of our extensive research test facility, enabled us to provide a line of high speed aerators which not only maximizes oxygen transfer and tank mixing characteristics but also achieving this in the most economical and reliable way. GSD' s surface aerator (SAR) uses a motor to directly drive the axial flow impeller, which discharges the waste water from the conduit through the water deflector and forms a thin (or water drop-shaped) water curtain. When contact with air during the transfer, it will form water drop shape, which fall to the water surface and form the turbulence and bubbles. These bubbles will improve oxygen dispersion and increase oxygen in water. The GSD SAR device pumps water from the bottom to the top and creates circulation flows and stir processes. It is suitable for domestic waste water treatment, agriculture and aquaculture oxygen supply and other industrial waste water aeration appli- cations. The chart below can be used to quickly estimate the horse- required power.
