Basic principles
Use activated sludge method to achieve the purpose of purifying sewage. Its principle: using the life activities of aerobic bacteria itself, in sewage, biological flocs formed by microorganisms
destabilize and flocculate suspended and colloidal organic pollutants, adsorb on the surface of activated sludge, degrade organic matter, and make BOD in the water. , COD dropped sharply.
Basic structure
It is composed of a single piece of multiple glass fiber reinforced plastic prefabricated components. The device is equipped with a dual-function aerator for underwater aeration and water
flow. When treating sewage, the sewage flows into the aeration area from the top of the device, and the aerator aerates underwater and pushes the flow to agitate the sewage. The incoming sewage
is quickly mixed with the original mixed liquid, and it can adapt to the change of influent water quality to a large extent. . The aerator has the dual functions of water flow and underwater
aeration, so that the sewage in the aeration area circulates regularly, and the dissolved oxygen content in the sewage is rapidly increased. As the sewage continuously circulates in the aeration
zone, the water quality at all points in the zone is relatively uniform, and the number and nature of microorganisms are basically the same, so the working conditions of all parts of the aeration
zone are almost the same. This will control the entire biochemical reaction under the same good conditions. Organic matter is gradually degraded by microorganisms, and sewage is
purified.
