NOVELTY - The device has water distribution clapboard (42) that is provided in bottom side of reactor shell (41) and connected with water inlet nozzle (43). Aeration system containing net-shaped anode (45) and columnar cathode (46) is provided in electrolytic reaction area of reactor shell set with water outlet weir plate (47). A spherical valve and cut-off filter device are provided in lower end of upper water pipe (48). Strain culture device and strain inducing device are connected with data analysis processing device. Display screen and printer are connected with strain fixed device.    USE - Mechanical vapor recompression (MVR)-repolarization electrolysis-bio-strengthening combined device for processing sewage.    ADVANTAGE - The net-shaped unit structure design can avoid water flow short circuit, improve the mass transfer effect, and the oxidation-reduction efficiency, so as to completely remove contaminants. The biochemical pool is immobilized with a special high efficient strain to polyvinyl acetate suspended filler, so as to enhance the organic matter removing effect. The processing efficiency can be greatly improved. Biochemical processing unit processed and discharges waste water after reaching the standard.    DETAILED DESCRIPTION - Self-sucking pump of conveying device is connected with immobilized heat preservation device. Biochemical tank is fixed with filler. The bottom of biochemical tank is provided with aeration pipe. The immobilized carrier from the pump is added to the biological pool. The outlet hot well in evaporating and concentrating unit is connected with the water inlet nozzle. Repolarization electrolytic processing unit is connected with upper centrifugal pump by pipeline.
