10.8 10.13 Japanese plant water samples analyzed water samples analyzed copper plant dope results: l PH = 12.6, Cu = 720ppm l RS100 dosage of 5g / L, and the filtrate was blue l RS100 dosage of 10g / L, and the filtrate Colorless, plus RS100 does not change color (possibly excessive) copper liquid processing results l PH = 12.6, Cu = 720ppm l RS100 dosage plus 5g / L, and the filtrate was blue l RS100 dosage of 10g / L, and the filtrate is colorless, plus RS100 does not change color (possibly excessive) existing l cyanide wastewater treatment processes: ion exchange → UF → RO → reuse - concentrated water discharged into the storm sewer nickel plating l: ion exchange → reuse, zero emissions l nickel : Electrolytic adjust PH → → → flocculation emissions - water about 0.3ppm (to be confirmed), came to an aging pool l Chemical Copper: After adding caustic soda and sodium sulfide and copper plating mix (not precipitated) - The new device uses Fenton oxidation process, the processing time is long, the water green l copper plating: ferrous sulfate sodium hydroxide → → → integrated wastewater flocculation acid wastewater l: l vertical integrated wastewater pond wastewater containing chromium: alkali reduction → → → comprehensive wastewater flocculation l integrated wastewater pond: alkali → recapture flocculation agents → → emissions - copper waste / water + acid waste water containing chromium wastewater - plus calcium and phosphorus, a reagent addition to the existing process COD shui _ Promise need rectification project: each share of wastewater metering pumps plus replacement dosing pump - Make sure the dosage
