Air-floating apparatus in coagulation floatation is soluble in water by large quantity of air under pressure condition, forms dissolved air water, is situated between as work
Matter generates a large amount of micro air bubbles by the release sudden pressure reduction quick release in coagulation floatation.Micro air bubble is anti-with coagulation
It answers the condensation product in waste water to be adhered to each other, wadding body specific gravity is made to bubble through the water column less than 1, so that pollutant be made to be separated from the water out
It goes, achievees the purpose that water purification.The water outlet of coagulation floatation flow to biological aerated filter certainly, attached on the filler in biological aerated filter
Microbial degradation organic matter, to achieve the purpose that water purification.The water outlet of biological aerated filter is divided into two gangs of 400m3/ d and
1600m3/ d, wherein 400m3/ d enters O3 contacted oxidation tower and carries out O3 contacted oxidation reaction, further decolourizes and removes
A small amount of COD, then qualified discharge；1600m3/ d is handled by dual membrane system, reverse osmosis unit output reuse water 1000m3/ d and
600m3/ d concentrated water (COD concentration 250mg/L), concentrated water enter Fenton reactor and carry out Fenton's reaction, and dilute sulfuric acid is first added and adjusts pH
3 or so, while ferrous sulfate and hydrogen peroxide is added, further removes pollutant, then water outlet is flowed into sedimentation basin and is precipitated, Gu
After liquid separation, liquid adjusts back pH with sodium hydroxide, then discharges water to blowoff basin outlet.
