PURPOSE:To purify the water in an ornamental fish water tank from the first by adding a microbe enriching agent for the protein decomposing bacteria, deaminating bacteria, ammonia oxidizing bacteria, nitrous acid oxidizing bacteria, nitric acid reducing bacteria, denitrifying bacteria, etc., to the water purifier. CONSTITUTION:Filthy water contg. dissolved org. matter is introduced into an aerobic module 7, the protein is decomposed into amino compds. by the protein decomposing bacteria and deaminating bacteria previously deposited on the surface of mineral matter 6, and the amino compds. are immediately decomposed into ammonia. The ammonia is oxidized and decomposed into nitric acid by the ammonia oxidizing bacteria and nitrous acid oxidizing bacteria previously deposited on the mineral matter 6. The nitric acid introduced into an anaerobic module 10 along with suspended org. matter is supplied with hydrogen from the org. matter and completely decomposed into nitrogen and water by the nitric acid reducing bacteria and denitrifying bacteria deposited on the surface of the mineral matter 6 and artificially cultured. Furthermore, the fungi pathogenic to fish grown in the water tank is sterilized by a UV lamp 12, and free chlorine in water is also removed. |
