The invention relates to a treatment device capable of intensifying degrading of wastewater containing azo dyes by a microbial electric auxiliary system and a water treatment method, belongs to the field of printing and dyeing wastewater treatment and mainly relates to wastewater treatment device and method. The invention aims to solve the technical problem that existing method of treating wastewater containing azo dyes is low in decolourization ratio of wastewater and poor in COD removing capacity. The device provided by the invention comprises a reactor anode collector plate, a reactor cathode collector plate, a reference electrode, a reactor water inlet, a mud discharge opening, a reactor perforated water distributing plate, a return pipe, a return pump, a lead, a water outlet, an anode filler layer clapboard, a cathode filler layer clapboard and a gas collecting opening. The water treatment method comprises the following steps that wastewater enters the treatment device capable of intensifying degrading of wastewater containing azo dyes by the microbial electric auxiliary system through the reactor water inlet; water is discharged from the water outlet to realize water treatment. The method provided by the invention is high in decolourization ratio of wastewater and high in COD removing capacity when used for treating wastewater containing azo dyes.read more
