Abstract：In agricultural production,livestock and poultry breeding wastewater,characterized by high concentrations of organic pollutants and antibiotic residues,has emerged as a critical source of water con-tamination.Photocatalysis,known for its environmentally friendly and efficient characteristics,offers promising prospects for eliminating refractory organic pollutants.Herein,Bi2MoO6/Bi2Sn2O7 composite photocatalytic materials were synthesized via a solvothermal method,followed by comprehensive charac-terization of their crystal structure,morphology,and elemental composition.Rhodamine B was employed as the target pollutant to assess the photocatalytic activity.The results demonstrated that the material ex-hibited optimal catalytic performance at a Bi2Sn2O7 mass fraction of 27%,achieving a degradation rate of 96.45%for Rhodamine B after 60 minutes of light irradiation.Further investigations were conducted to e-valuate its treatment efficacy on actual livestock and poultry breeding wastewater.After 180 minutes of light exposure,the removal rates of total nitrogen(TN)and total phosphorus(TP)reached 44.42%and 84.97%,respectively,while the chemical oxygen demand(COD)removal rate stood at 70.23%.In vitro cytotoxicity assays and phytotoxicity tests confirmed that the material possessed excellent biocompatibility within the experimental concentration range.This study offers an environmentally benign and innovative strategy for agricultural wastewater treatment.
