The composite pollutants formed by antibiotics and heavy metals in livestock and poultry wastewater and their metabolites have the characteristics of strong persistence, non-degradability and easy accumulation. They will exist in the environment and the human body for a long time, which may lead to a series of ecological and environmental And health problems. Recently, the Long Yunlu team of the School of Environment of Sichuan Agricultural University successfully designed and developed a new type of double-chamber electrocatalytic system focusing on”combined pollution treatment of antibiotics and heavy metals in livestock and poultry wastewater”.
The system uses the highly adsorbable three-dimensional reduced graphene oxide as the electrode, and makes full use of its strong electron transport and enrichment capabilities to successfully remove tetracycline (TC) in the anode compartment; copper ions in the cathode compartment. In addition, based on the dual-chamber electrocatalytic system, α-MnO2 as the electrode, coupled with activated PMS advanced oxidation technology, the synergy between anode electrocatalytic technology and activated PMS technology successfully removed the combined pollution of TC and hexavalent chromium It provides new theoretical support and technical basis for the removal of composite pollutants formed by antibiotics and heavy metals in water bodies. Related results have been published online in the internationally renowned journals Journal of Cleaner Production”Clean Production” (Top 1, IF=7.246, Chinese Academy of Sciences) and Chemical Engineering Journal (TOP 1, IF=10.652, Chinese Academy of Sciences).
