STAINLESS STEEL-BASED LANTHANUM/SAMARIUM/CERIA ANTI-POLLUTION ELECTRODE FILM AND PREPARATION PROCESS AND APPLICATION THEREOF

The invention relates to a stainless steel-based lanthanum/samarium/ceria anti- pollution electrode film and a preparation process and application thereof, and belongs to the technical field of sewage purification and wastewater resource utilization, including the following steps: 1) pretreatment of stainless steel mesh; 2) preparing lanthanum/samarium/ceria electrocatalyst; 3) preparation of stainless steel-based lanthanum/samarium/ceria anti-pollution electrode film, where the stainless steel- based lanthanum/samarium/ceria anti-pollution electrode film is prepared by thermally induced phase separation method with the stainless steel mesh obtained in step 1) as the substrate and the lanthanum/samarium/ceria electrocatalyst obtained in step 2) as the raw material. The stainless steel-based lanthanum/samarium/ceria anti-pollution electrode film is applied to the coupling system of microbial fuel cell (MFC) and film bioreactor (MBR), and the treatment process is optimized, thus realizing the treatment of high-load organic wastewater in tanning wastewater and the removal of heavy metal ions.
