PURPOSE: To decompose and clean up effectively hydrocarbons, nitrogen, inorganic salts, metal elements, and others by immobilizing aerobic microorganisms which convert pollutants, eutrophic sources for ponds, lakes and marshes, into resources on a ceramic plate, etc., and bringing eutrophic source water into contact with the aerobic microorganisms.
CONSTITUTION: A cleaning machine 2 is installed at a proper position in a pond 1 of polluted water, and in the middle of the pond, water is ejected from a nozzle by a pump in order to agitate the polluted water. An ejector is installed which is agitating water by sucking external air when water is ejected. In the cleaning machine, a discharge pipe 8 and an external air suction pipe 9 of a submergible motor pump are connected to the opening of one end of a cylinder 10, an air mixing water ejection pipe 11 is connected to the opening of the other end, and the cylinder 10 is packed with cleaning media 12 in which microorganisms such as Oppenheimer Bio are immobilized on granular porous ceramics. Sludge, etc., which are floating by the action of the ejector, are sucked and collected to be decomposed for effective cleaning.
