Electrolysis apparatus for nitrate nitrogen or ammonia nitrogen or phosphorus comprised in waste water or polluted water

摘要

PURPOSE: An electrolysis apparatus for removing ammonia nitrogen, nitrate nitrogen, and phosphorus from sewage is provided to implement stirring in sewage without a stirrer by the flow of gas and water produced from electrolysis. CONSTITUTION: An electrolysis apparatus for removing ammonia nitrogen, nitrate nitrogen, and phosphorus from sewage comprises a water tank(10), a cathode tube(20), an anodic electrode, and a power supply device(40). The water tank has an inlet on one side and an outlet(12) on the other side. The top of the cathode tube is protruded from the top of the water tank while the bottom is submerged in sewage. The cathode has a suction opening(21) at the bottom and a plurality of discharge holes(22) on the side wall and the bottom of the cathode tube is separated from the bottom of the water tank. The anodic electrode is vertically inserted in the center of the cathode tube and 5-25mm separated from the inner periphery of the cathode tube. The power supply unit supplies power to the cathode tube and the anodic electrode. The total area of the discharge holes is 0.01-0.2 times the total area of the outer periphery of the cathode tube.
