Water purification equipment containing dissolved organic matter and trace amounts of harmful substances

摘要

PROBLEM TO BE SOLVED: To provide a method for decomposing and purifying harmful substances in various waste water by oxidation or reduction. SOLUTION: Liquid mixed fine particles of titanium oxide, cobalt oxide, tin oxide, iridium oxide, nickel oxide, iron oxide, or vanadium oxide or metallic fine particles of titanium, cobalt, nickel, silver, or gold or these mixture with the same kind of metallic salt solution is coated on a surface of ceramics consisting essentially of feldspar or silicon, titanium, iron, or stainless steel, and is dried, then sintered at 500-1500 deg.C temperature range, thus a produced positive electrode consisting of the metal oxide, metal, or these mixture, and a negative electrode consisting of platinum, titanium or stainless steel are arranged to face each other to form a radical generation part. Waste water is made to continuously flown between both the electrodes facing each other, and pulse discharge is generated between both the electrodes, and the organic matters dissolved in water and the intermediate products are oxidized or reduced and decomposed.
