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...
