ELECTROCHEMICAL TREATMENT OF SERVICE WATER AND WASTE WATER

PURPOSE:To make it possible to treat service water or waste water with good efficiency, by arranging an anode and a cathode in a container filled with a liquid to be treated such as service water or waste water and applying accumulated high voltage between both electrodes as a pulse. CONSTITUTION:An anode 3 and a cathode 4 are arranged in a container 2 filled with a liquid 1 to be treated such as service water or waste water and a pulse current generation apparatus 6 is respectively connected to the anode 3 and the cathode 4 so that a current converted to a pulse current is applied to both electrodes 3, 4 from a high voltage generation power source 5 and the electric field generated by the anode 3 and the cathode 4 holds minus potential to earth 7. By this mechanism, high voltage is applied to the liquid 1 to be treated as a pulse. By this method, service water or waste water can be treated efficiently by one process and an available chlorine amount, ORP (redox potential) or COD (chemical oxygen demand) can be certainly reduced and, therefore, this method is optimum as the treatment method of service water or the like.
