A method for resourceful treatment of glutathione bulk drug production wastewater
By converting reduced triphosphonates into salts and separating them by nanofiltration, using iron-carbon microelectrolysis, anaerobic ammonia oxidation, and heterogeneous photo-Fenton treatment, the problems of glutathione resource waste and low pollutant treatment efficiency have been solved, achieving efficient resource recovery and stable degradation, and reducing costs and hazardous waste generation.

AI Technical Summary
Existing technologies are difficult to efficiently recover glutathione, leading to resource waste. At the same time, the processing costs are high and there is a risk of secondary pollution. Traditional denitrification processes are inefficient and unstable in operation.
A four-stage synergistic treatment system was constructed by converting reduced triphosphonate into oxidized glutathione, combined with nanofiltration separation, iron-carbon microelectrolysis pretreatment, anaerobic ammonia oxidation coupled with A²/O biochemical treatment, and heterogeneous photo-Fenton deep treatment, to achieve resource recovery and efficient degradation of pollutants.
It achieves high-efficiency recovery of glutathione and removal of pollutants, reduces operating costs, reduces the generation of hazardous waste, produces effluent that meets standards and can be reused, and has strong system stability.
