Integrated photoelectrocatalysis-membrane separation fluidized bed reaction device

Abstract

The invention discloses an integrated photoelectrocatalysis-membrane separation fluidized bed reaction device. The reaction device comprises a housing, an ultraviolet source, an electrode plate, a membrane component and an aerating unit. A water inlet and a water outlet are formed in the bottom of the housing. The aerating unit, the ultraviolet source, the electrode plate and the membrane component are arranged in the housing. The membrane component is connected with the housing. The distance between the ultraviolet source and the membrane component as well as the distance between the electrode plate and the membrane component are larger than or equal to the penetrating distance of ultraviolet light and the reaction distance of the electrode plate respectively. According to the integrated photoelectrocatalysis-membrane separation fluidized bed reaction device, multiple functions, including a photocatalysis function, an electrocatalysis function and a membrane separation function, are achieved, the mass transfer performance is good, the catalyst utilization efficiency is high, the catalyst can be recycled, waste water treatment efficiency is high, the structure is simple, and energy consumption is reduced.

Description

technical field [0001] The invention relates to an integrated photocatalysis and electrocatalysis reaction device, in particular to an integrated photocatalysis-membrane separation fluidized bed reaction device. Background technique [0002] In recent years, with the rapid development of my country's national economy, my country's environment has been seriously polluted and the ecology has been irreversibly damaged. Among them, the lack of water resources has become an important factor restricting the development of my country's national economy, while the pace of industrial and agricultural structural adjustments is relatively lagging behind, resulting in large consumption of water resources, low utilization efficiency, and water pollution. Therefore, while speeding up the adjustment of industrial structure, it is particularly necessary to realize rational and efficient use of water resources, to realize effective treatment of industrial and agricultural wastewater and to r...
