A kind of advanced treatment method of heavy metal sewage in landfill |
| abstract |
The invention discloses a method for advanced treatment of heavy metal sewage in a landfill, comprising the following steps: pretreatment; pH value adjustment; introducing a coagulant equivalent to the amount of the remover in a coagulation tank, and stirring for 5-20min; Introduce 0.1%-0.3% composite flocculant into the flocculation tank, slowly stir for 5-15min and then settle for 20-60min; adopt plasma catalytic oxidation water treatment system to react for 1-2h; RO treatment; recycling treatment. The removing agent in the present invention has strong chelating ability, can form completely water-insoluble chelating sediment with heavy metals, can treat different types of heavy metal wastewater, and the composite coagulant has strong adsorption capacity and can effectively remove landfill leachate Organic pollutants, heavy metals and harmful components in the waste; the present invention is also provided with a multi-stage purification device to carry out advanced treatment of heavy metal sewage in the landfill, thereby avoiding the pollution of heavy metal sewage. |
