An integrated device and method for treating toxic and refractory wastewater are provided. The integrated device includes an adjusting pool, a first-stage reactor, a second-stage reactor, a third-stage reactor, a coagulation sedimentation pool, and a biochemical reaction pool that are sequentially connected in series, and further includes an aeration blower. Each of the first-stage reactor and the third-stage reactor is an advanced oxidation reactor, and the second-stage reactor is a Fenton reactor. The coagulation sedimentation pool includes 2 to 4 stages, and each stage of the coagulation sedimentation pool includes a coagulation tank, a primary sedimentation tank, and a secondary sedimentation tank that are connected in series. The biochemical reaction pool includes an anoxic tank, an aerobic tank, a settling tank, and a clean water tank that are connected in series. The wastewater treatment method combines the integrated device for treating toxic and refractory wastewater with reasonable process parameters.

A method for electrolysis-ozone-corrosion inhibitor/electrolysis-ozone-hydrogen peroxide-corrosion inhibitor coupling treatment on toxic and refractory wastewater includes the following steps: adding toxic and refractory wastewater to be treated into a wastewater treatment reaction tank equipped with a plate anode and a plate cathode, and starting a direct current (DC) power supply connected to the plate anode and the plate cathode to treat the toxic and refractory wastewater at an appropriate current density under stirring, during which a corrosion inhibitor and hydrogen peroxide are added to the toxic and refractory wastewater to be treated and ozone is introduced into the toxic and refractory wastewater to be treated through an aeration device. The method can increase the production rate and production quantity of free radicals in a reaction system, effectively improve the treatment efficiency for toxic and refractory wastewater, and reduce the treatment cost.
