| titleOfInvention | A kind of processing method of high concentration chrome wastewater |
| abstract | A kind of processing method of high concentration chrome wastewater, specific method are:Sewage is discharged into reaction tank by A.The content of Cr VI, is measured by titration in B monitoring reaction tanks.C adds sodium hydrogensulfite into reaction tank, by chromium and the mass ratio 13 of sodium hydrogensulfite：45 inputs；PH value is adjusted between 23, oxidation-reduction potential is reduced to trivalent chromium in 200 230mv in the presence of sodium hydrogensulfite.After D is using mechanical arm stirring, draws fluid into filtering ponds and filter off except trivalent chromium sediment, water after being handled.Method provided by the invention during can metalwork be manufactured caused Cr VI reduced, trivalent chromium is obtained, and is stirred by mechanical arm in reaction tank, makes this reaction more abundant, the precipitation of trivalent chromium is realized by alkaline filter pond, avoids injury of the high concentration chrome wastewater to people. |
