The invention relates to an elution-method soil remediation process. The process comprises the steps of feeding, performing preliminary screening separation, performing fine screening separation, performing acid mixing pool oxidization, performing solid-liquid separation, reducing metal ions, precipitating metal ions, flocculating organic insoluble substances, performing precipitation separation and performing filter pressing treatment. The process has the beneficial effects of adopting preliminary screening eluting and fine screening eluting for separating heavy metal ions and other pollutants into water from soil, combining the metal ions and anions in acid through oxidization in two-stage acid mixing pool, dissolving the mixture in water, performing centrifugal separation, reducing pollutant-containing water through an alkali pool, reacting the water and hydroxyl to separate precipitates from sewage, flocculating the precipitates and settling the precipitates in a four-stage settling pond for solid-liquid separation, wherein the separated water can be recycled to be used for preliminary screening eluting and fine screening eluting, the pollutant-containing solids are discharged and then fed into a filter press for filter pressing recovery, and water, which is generated in the filter pressing process and contains a few of pollutants, is fed back to a sewage pool for treatment and separation again.
