specific Embodiment 1
[0055] The raw waste water mainly contains cyanide, ammonia nitrogen, SS and organic matter. After being treated in the original factory area, the main pollutant indicators are COD≤80mg / L, ammonia nitrogen≤35 mg / L, total nitrogen≤50 mg / L, and total cyanide≤0.5 mg / L L. Wastewater passes through high-efficiency coagulation decyanation reactor, biological aerated filter, denitrification filter, V-shaped filter and ozone catalytic oxidation tank in sequence. Through a high-efficiency coagulation decyanation reactor, the total cyanide and part of SS are removed under the action of a high-efficiency coagulation decyanation agent; the biological aerated filter and denitrification filter use ceramsite with a particle size of 3~5mm The filter material, through the nitrification and denitrification of aerated biological filtration and denitrification filter, removes ammonia nitrogen and total nitrogen in wastewater; further removes SS in wastewater through a V-shaped filter, which plays...

[0058] The raw waste water mainly contains cyanide, ammonia nitrogen, SS and organic matter. After being treated in the original factory area, the main pollutant indicators are COD≤100mg / L, ammonia nitrogen≤35 mg / L, total nitrogen≤50 mg / L, and total cyanide≤1 mg / L L. Wastewater passes through high-efficiency coagulation decyanation reactor, biological aerated filter, denitrification filter, V-shaped filter and ozone catalytic oxidation tank in sequence. Through a high-efficiency coagulation decyanation reactor, the total cyanide and part of SS are removed under the action of a high-efficiency coagulation decyanation agent; the biological aerated filter and denitrification filter use ceramsite with a particle size of 3~5mm The filter material, through the nitrification and denitrification of aerated biological filtration and denitrification filter, removes ammonia nitrogen and total nitrogen in wastewater; further removes SS in wastewater through a V-shaped filter, which plays ...
