MANUFACTURING METHOD OF NANO-METAL PINE BIOCHAR FOR REMOVING PHOSPHORUS AND NANO-METAL PINE BIOCHAR MANUFACTURED USING THE METHOD

摘要

The present invention relates to a pine bio tea producing method capable of removing phosphorus from sewage and, more specifically, to a method for producing bio tea by modifying the surface of bio tea with nanometal in order to increase the phosphorus adsorption performance of pine bio tea. To achieve the above purpose, the producing method of nanometal pine bio tea for removing phosphorus comprises: a first step of washing pine trees with flowing tap water; a second step of drying the pine trees indoors; a third step of producing pine sawdust by pulverizing the dried pine trees with a pulverizer; a fourth step of producing biomass by drying the produced pine sawdust at 75-85°Cfor three hours; a fifth step of processing the surface of the biomass by stirring the biomass in FeCl_3·6H_2O solution for two hours and drying the same; and a sixth step of pyrolyzing the biomass surface-processed after drying by injecting nitrogen gas at a flow rate of 2,500 cm^2/min in a pyrolyzer and blocking air from flowing into the pyrolyzer.
