Abstract
The present invention discloses a gas, liquid, and solid three-phase distributor, a circulating biological filter tank and an aeration method. The three-phase distributor is located at the bottom inside the circulating biological filter tank; the distributor is hollow inside; side walls of the distributor define a cone; aeration holes are arranged on the side walls of the distributor that define a cone; and a conical surface formed by the side walls uniformly distributes falling filtered materials. An aeration apparatus is arranged in a lower space of the distributor; air introduced by the aeration apparatus and water in the lower space of the distributor achieve an air-water mixing and stirring effect; excess air escapes the water, forms an underwater air chamber in an upper space of the distributor, and then is diffused along the aeration holes in the side walls of the distributor into a filter layer outside the distributor. The three-phase distributor provided by the present invention achieves gas-liquid-solid uniform distribution.
