摘要： A fungal culture is provided that incorporates concentrations of Fenton reactants and white rot fungi biomass. These components synergize to degrade recalcitrant organic compounds such as lignins, perfluorochemicals including PFOA, plastics, and related compounds, particularly with 1.5 mM H2O2, 1 mM Fe2+, and Phanerochaete chrysosporium exhibiting lignin degrading capabilities comparable to cultures of Fenton-only reaction mediums with significantly higher concentrations of hydrogen peroxide. Both the fungi and the Fenton reactants work to degrade the organic compounds. Additionally, the Fenton reactants impose oxidative stress on fast-growing microbial competitors such as E. coli, selectively inhibiting the competing bacteria and their disadvantageous effects on white rot fungi activity. The white rot fungi recycle Fe(II) ions to reduce Fenton reactant input burden. An electro-Fenton reaction process can further reduce this burden by replenishing H2O2. The resulting systems and methods demonstrate more economical and sustainable treatment of recalcitrant organic compounds.

摘要： Provided is a method of manufacturing a high-purity lithium phosphate by utilizing a lithium waste liquid of a wasted battery. Lithium phosphate is manufactured and refined by using a minimized amount of sodium hydroxide and by using phosphate, lithium hydroxide, and an optimized pH condition, so that it is possible to manufacture high-purity lithium phosphate from which fine impurities which cannot be removed by cleaning are effective removed. A waste water treatment process of processing waste water as to be immediately discharged is integrated, so that the method is very efficient and environment-friendly. Therefore, since the high-purity lithium phosphate can be manufactured by utilizing a lithium waste liquid discarded in a wasted battery recycling process, the method has an effect in that the method is applied to a wasted battery recycling industry to prevent environmental pollution and facilitate recycling resources.

摘要： Provided is a method of manufacturing high-purity, high-quality manganese sulfate which can be immediately used for manufacturing a lithium ion secondary battery from manganese sulfate waste liquid of a wasted battery. Since impurities are removed from the manganese sulfate waste liquid by using sulfides causing no secondary contamination in the manganese sulfate waste liquid and the manganese sulfate is manufactured by performing evaporation concentration through heating, the manufacturing method is very environment-friendly and economical. Since the manganese recovering process improving the manufacturing yield of the manganese sulfate and the waste water treatment process capable of recycling the source materials and discharging waste water are integrated, the manufacturing method is very efficient and environment-friendly. The manufacturing method is applied to the recycling industry, and thus, it is possible to obtain effects of preventing environmental pollution and facilitating recycling the resources.
