A catalyst for catalytic oxidation of dichloromethane in wastewater and wastewater treatment process |
| abstract |
The invention discloses a catalyst for catalytic oxidation of dichloromethane in waste water and a waste water treatment process. The catalyst is composed of a carrier, an active component and a complexing agent, and the specific components are as follows: the carrier is diatomite or activated carbon, 500-900 g; the active component is ferrous sulfate (FeSO 4 ยท7H 2 O), 50- 150g; the complexing agent is disodium ethylenediaminetetraacetate (EDTA), 5-10g. The treatment process includes three steps: the first step is the pretreatment of the waste water containing dichloromethane, and the pH value of the waste water is adjusted to 2.0-4.0 by hydrochloric acid; 0.5-1.5 g of catalyst and 20-100 g of oxidant (hydrogen peroxide) are added to the medium, and the mixture is stirred for 10-24 hours; the third step is to separate the solid catalyst and the treated wastewater by filtration. Under optimal conditions, the removal rate of dichloromethane can reach 87.8% after the treatment of industrial wastewater containing dichloromethane. The catalyst of the invention has the characteristics of long service life and simple and convenient regeneration. |
