A method for producing heavy water from sludge is provided to remove a hardly-decomposable organic material, ammonia nitrogen, and a colorant-inducing material, etc., which are contained in the sludge efficiently, by installing an electrolytic device at the rear of a sludge-treating apparatus. A water treatment process is performed by using a precipitation bath, a screen bath, a flow rate-regulating bath, an anaerobic bath, an aerobic bio-membrane bath, a submergence type filtering bath, a treated water storage bath, an activated carbon-filtering unit, and a sludge storage bath. An electrolytic bath is installed at the rear of the activated carbon-filtering unit. The electrolytic bath has an electrolytic device(11) therein. The electrolytic device includes a niobium anode electrode plate(12) coated with platinum, a cathode electrode plate(13) of SUS(Steel Use Stainless), and a gap member disposed between the anode electrode plate and the cathode electrode plate. A hardly-decomposable organic material, ammonia nitrogen, and a colorant-inducing material are oxidized by hydroxyl radicals formed at the anode electrode plate. Further, the gap member is made from an LDPE(low density poly ethylene) of which a density is 0.912-0.94 g/cm^3, a crystallinity is 50%. |
