Abstract
A three-dimensional electrode-ozone oxidation-electrocatalytic membrane coupled wastewater treatment device, including a circulating fluidized bed reactor. The circulating fluidized bed reactor includes a funnel-shaped internal, a truncated cone, a fiber ball filter, a gas-liquid distribution plate, an inner cylinder, an intermediate cylinder and an outer cylinder. The inner cylinder, the intermediate cylinder and the outer cylinder are coaxial. The inner cylinder is an electrocatalytic membrane assembly; the intermediate cylinder is a gas diffusion electrode; and the outer cylinder is a stainless-steel mesh. A particle electrode is filled between the intermediate cylinder and the outer cylinder, and between the intermediate cylinder and the inner cylinder. The intermediate cylinder is connected to a negative electrode. The inner cylinder and the outer cylinder are connected to a positive electrode. A wastewater treatment method using the device is also provided herein.
