Treatment Of Water By Oxidation Or Reduction
(AREA)
Abstract
The method, a process for waste water treatment, can mainly deal with high contamination from waste and include the following steps: The first step: leachate after biological treatment was treated by Fenton and removed Cl ion and No2 ion. The second step: add excess Fe2- or Fe3- and Fe1- or Fe3- and H2O2 under the condition of PH=2.5~4.0 to react for 10~60 min to proceed Fenton. The solutions by the reaction are precipitated. The third step: The above clear solutions are treated by S2O82- and Fe2- under the condition of PH=3.0~6.0 for 10~50min.The S2O82- and Fe2-was used for further oxidation after Fenton reaction and it would not interrupted by Cl1-. The process for COD removal of leachate can add to.
