APPARATUS FOR PURIFYING WATER USING MICROALGAE

摘要

The present invention provides an apparatus for purifying water which can purify water by making aerobic microorganisms use photosynthetic oxygen produced by microalgae, and at the same time produce algae of high purity. The apparatus for purifying water comprises: i) a photosynthetic reaction unit into which contaminated water flows and in which light is irradiated; ii) a plurality of meshes for attaching algae which are obliquely installed within the photosynthetic reaction unit and spaced apart from each other; iii) a nitrification unit which is located below the photosynthetic reaction unit, accommodates a plurality of carriers having aerobic microorganisms attached thereto which lead to a nitrification reaction of the contaminated water using oxygen produced in the photosynthetic reaction unit, and produces liquid subjected to nitrification; iv) an oxygen supply unit which is located below the plurality of carriers and adapted to supply additional oxygen to the nitrification unit; and v) an algae collection unit which is connected to the photosynthetic reaction unit to collect algae desorbed from the plurality of meshes for attaching algae.
