Performance of carbon felt as cathodes in magnesium corrosion method to recover phosphate from swine wastewater.

With the large-scale development of the livestock and poultry breeding industries, swine wastewater with high nitrogen and phosphorus concentrations has become an urgent problem. Given the continuous demand for phosphorus resources in industrial production, the study of phosphate recovery in phosphorus-rich wastewater is of great value for the sustainable utilization of phosphorus resources and for alleviating the eutrophication of aquatic ecosystems. In this study, a magnesium metal corrosion method was used to recover phosphorus resources from swine wastewater using carbon felt as the cathode instead of traditional cathode materials such as graphite and titanium plates.
