METHOD FOR PURIFYING LAKE OR MARSH WATER AND BOAT FOR PURIFYING DIRTY WATER

PURPOSE:To uniformly purify lake or marsh water by a simple operation in a short time while saving energy by using a boat for purifying dirty water loaded with an electrolytic apparatus, a DC power source unit, a flocculant injector and a flock recovering apparatus. CONSTITUTION:Many electrode plates 91, 92 are parallel fitted to props 10, 11 at proper intervals, each fluorite basket is suspended between the plates 91, 92 and a nozzle pipe 8 for injecting a flocculant is laid in front of the plates 91, 92. The resulting electrolytic apparatus is suspended at the lower part of a boat for purifying dirty water, a flock recovering apparatus 12 is fitted to the rear part of the boat and a DC power source unit 5 and a flocculant tank 3 are set on the boat. The electrolytic apparatus is worked while running the boat in a lake or marsh.
