Abstract

The invention discloses an anaerobic-aerobic three-dimensional electrocatalytic coupling water purification system and a water purification method. The three-dimensional particle electrode layer of the anaerobic-aerobic three-dimensional electrocatalytic coupling water purification system is located on the upper part of the adsorption-type biological filter material layer. The three-dimensional particle electrode layer and the adsorption-type biological filter material layer are connected through a plastic porous plate. The anode of the electrode is connected to the cathode of the main electrode in the middle. The anode of the main electrode and the cathode of the main electrode are made of titanium mesh and stainless steel respectively. The catalytic particle electrode is filled between the main electrodes. The water distribution chamber is connected with a reflux device, and the aeration plate divides the adsorption-type biological filter material layer into an anaerobic section and an aerobic section. The water purification method of the present invention includes the following steps: (1) mixing the raw water with the backflow water in the water distribution chamber; (2) physical filtration and interception; (3) anaerobic / aerobic biological treatment to remove organic matter and denitrification; (4) Advanced oxidation; (5) clean water. In the water purification system of the present invention, its anaerobic, aerobic, and advanced catalytic oxidation are coupled in the same reactor, and each stage in water treatment cooperates with each other, and under the interaction of physical filtration, anaerobic / aerobic treatment, and advanced oxidation, The predetermined treatment effect is achieved, and the effluent water quality is stable.

Description
