| Abstract: | Advanced treatment of printing and dyeing wastewater by joint oxidation technology of iron-carbon micro-electrolysis and Fenton reagents was studied.The influence of pH,H2O2 adding amount,the volume ratio of iron to carbon on treating effect was studied.It is found that the best experimental conditions are as follows: pH is 2～3,H2O2 dosage is 3.2 mL/L,volume ratio of iron to carbon is 1 ∶1,reaction time 90 min.Under this condition,the removal of COD,chroma and salinity can reach 90%,99% and 64%,respectively.Each index met the reuse requirements of printing and dyeing water. |
