The invention discloses a filter membrane synchronous catalytic filter device and a method thereof, which include a water inlet cross-flow unit, an electrocatalytic unit and a drainage recoil unit. The main bodies of the three units are all composed of plexiglass cavities, and pass through from top to bottom. The bolts are connected in sequence; the three units are connected to each other, and there are water inlet holes and cross-flow holes on one side of the cross-flow unit; the bottom of the cross-flow unit is equipped with a permeable orifice plate, and a conductive filter is attached to the permeable orifice plate. The conductive filter membrane is connected to the negative electrode of the DC power supply through the embedded wire and the conductive copper sheet; the top of the electrocatalytic unit has a through hole for placing the catalytic electrode, and the catalytic electrode is arranged in parallel on the side wall of the through hole and connected by the embedded wire Conductive copper and connected to the positive pole of the DC power supply. The conductive filter membrane and the electrocatalytic electrode form an electric field, and the filter membrane repels the negatively charged pollutants in the water, while the electrocatalytic electrode absorbs the negatively charged pollutants in the water for catalytic oxidation degradation.
Description
technical field [0001] The invention belongs to the technical field of filter membrane sewage treatment equipment, and relates to a filter membrane synchronous catalytic filter device and a filter method of the device. Background technique [0002] With the continuous improvement of water treatment requirements, membrane filtration water treatment has become one of the commonly used methods in the advanced treatment of drinking water and sewage, and has been widely used in the sewage treatment industry. However, the membrane fouling caused by adsorption and deposition on the surface of the membrane has been restricting the development of the membrane filtration technology. Conventional chemical cleaning has a large damage to the membrane surface and the cleaning effect is very limited. Contents of the invention [0003] The purpose of the present invention is to provide a filter membrane synchronous catalytic filter device and its method, synchronously using the filter mem...
