The specific embodiment
Below in conjunction with the drawings and specific embodiments, the utility model is described in further detail, so that those skilled in the art can better understand the utility model being implemented, but illustrated embodiment is not as to restriction of the present utility model.
As shown in Fig. 1 ~ 3, the elution device of polluted soil of the present utility model, contain the clean post 5 of leacheate holder 1, drip washing post 4, leacheate and the leacheate collector 6 that connect in turn;
Be filled with successively from top to bottom polluted soil layer 41, sand stone layer 42 and filter membrane 43 in drip washing post 4;
Be filled with successively from top to bottom fine sand layer 51, active carbon layer 52 and filter membrane 53 in the clean post 5 of leacheate.
Wherein, between leacheate holder 1 and drip washing post 4, be provided with peristaltic pump 3, peristaltic pump 3 is communicated with leacheate holder 1 and drip washing post 4 by pipeline 2.
Gravel size in sand stone layer 42 is greater than 1mm, is conducive to the diffusion of leacheate.
In fine sand layer 51, gravel size is 0.5 ~ 1mm.
Drip washing post 4 is uncovered lucite tube, and its bottom is funnel-form.
It is uncovered lucite tube that leacheate cleans post 5, and its bottom is funnel-form.
Leacheate cleans post 5 and can be set to, more than two, be connected in series.
Active carbon in active carbon layer 52 is graininess.
It is example that the reparation of take is subject to the soil of heavy metal pollution, during concrete enforcement, filter membrane, granular active carbon and fine sand are filled into to the clean post 5 of leacheate successively, filter membrane, sandstone and polluted soil are filled into to drip washing post 4 successively, leacheate is injected to leacheate holder 1, connect device, start, the drip washing experiment starts.Peristaltic pump 3 is delivered to drip washing post 4 by the leacheate in leacheate holder 1 by pipeline 2, polluted soil layer 41 in drip washing post 4 is carried out to drip washing, (can effectively prevent that soil from flowing into the clean post 5 of leacheate) after sand stone layer 42 and filter membrane 43 filtrations, leacheate enters the clean post 5 of leacheate, 51 pairs of leacheates of fine sand layer purify, heavy metal ion in the granular active carbon absorption leacheate of active carbon layer 52, after filter membrane 53 adsorption filtrations, leacheate flows into leacheate collector 6.(in the leacheate collector 6) leacheate produced is at the beginning detected, detect and qualifiedly can directly enter sewer pipe; The defective quantity (series connection arranges) that can suitably increase the clean post 5 of leacheate, until reach direct emission request.
The utility model selects fine sand, granular active carbon to clean the packing material of post 5 as leacheate.Fine sand is effective purifying water body both, has played again the effect of compacting active carbon; Active carbon is the good material of Adsorption of Heavy Metal Ions.
The above embodiment is only the preferred embodiment for absolutely proving that the utility model is lifted, and protection domain of the present utility model is not limited to this.Being equal to that those skilled in the art do on the utility model basis substitutes or conversion, all within protection domain of the present utility model.Protection domain of the present utility model is as the criterion with claims.
