Abstract

The invention relates to the field of groundwater pollution control and remediation, and particularly relates to a permeable reactive wall material and a preparation method thereof. The permeable reactive wall material provided by the invention comprises the following components in percentage by weight: 45%-55% of iron powder, 5%-10% of zeolite and 40-50% of activated carbon, wherein the percentage sum of the components is 100%. According to the preparation method, iron powder, zeolite and activated carbon are mixed in a specific proportion, so that the comprehensive treatment efficiency of the materials on water pollutants is improved, the use amount of the reaction materials is reduced, the production and construction cost of the product is reduced, and the market competitive power is enhanced.

Description

technical field [0001] The invention relates to the field of groundwater pollution control and restoration, in particular to a permeable reactive wall material and a preparation method thereof. Background technique [0002] The permeable reaction wall technology is a pollution treatment system that installs specific active reaction medium materials below the ground in order to achieve a certain environmental pollution control goal. When the polluted groundwater passes through, the pollutants and the reaction medium will undergo physical and chemical reactions. It is degraded, adsorbed, precipitated or removed by the action of living organisms, etc., and the pollutants in it are converted into environmentally acceptable forms. Taking the landfill as an example, once the anti-seepage membrane of the landfill is broken, the leaked leachate will pollute the soil and water outside the landfill. In order to prevent or stop the pollution caused by leachate leakage, a permeable rea...
