Description
Technical field
This utility model belongs to technical field of soil remediation, is specifically related to a kind of elution device removing heavy metal in soil, is used for the process by heavy-metal contaminated soils such as lead zinc and reuse.
Background technology
Due to world population sharp increase and the fast development of industrial or agricultural, Soil Environmental Pollution problem has become the principal element of harm global environment quality.Heavy metal pollution of soil problem, because of features such as big, length incubation period of its hazardness, is the most progressively paid close attention to by industry.But because of problems such as heavy metal pollution of soil recovery technique are complicated, intractability is big, processing cost is high, industry technology development is slower.
The method that soil pollution processes totally divides and can be divided into physics, chemistry and biological method.Physical method can include the methods such as machinery is digged, soil moved in improve the original dilution.But this method disadvantageously, the physicochemical properties that may result in soil change because the oxidation-reduction potential of deep soil is different, so may allow some material generation redox reaction after digging, produce negative effect.Chemical method includes electrochemistry, drip washing, air stripping etc..But the problem of chemical method is, medicament used may produce secondary pollution.A kind of environmentally friendly method of biological method.Such as phytoremediation, microorganism remediation, and plant-microorganism combine d bioremediation.But it is longer that the shortcoming of the method is repairing efficiency, and efficiency is low, and cost is relatively large.
Summary of the invention
The purpose of this utility model is to provide a kind of elution device removing heavy metal in soil, makes the soil by heavy metal pollution be purified, and alleviates it to the pollution of environment and the impact on contaminated site periphery health of the masses.
The technical scheme that this utility model is given is: a kind of elution device removing heavy metal in soil, including housing, it is located at the agitator of enclosure interior, housing is provided with the incubator for cultivating acidophilic thiobacillus, incubator is provided with the contact hole contacted for soil with acidophilic thiobacillus, and described incubator is fixed on housing by support；It is provided with feed pipe in lower housing portion, is provided with discharge nozzle in housing side, be provided with the discharging tube for discharging leacheate in discharge nozzle bottom, be additionally provided with return duct in housing side；It is provided with a steam vent at housing upper.
The beneficial effects of the utility model are: device of the present utility model utilizes microbial technique to process the heavy metal such as lead, zinc in contaminated soil, has low cost, the advantage that the feature of environmental protection is good；Incubator is set in device, makes microorganism culturing simple and efficient, with entering beneficially its contacting with soil, improve the treatment effect of heavy metal, treatment effeciency can be effectively improved；Leacheate rich in heavy metal ion can discharge and reclaim metal contained therein, improves the utilization of resource and has certain economic worth.
This utility model also has simple in construction, it is simple to the advantage of maintenance.
Accompanying drawing explanation
Fig. 1 is this utility model structural representation；
Fig. 2 is the cross-sectional view of Fig. 1.
Sequence number explanation in figure: 1 housing, 2 incubators, 3 supports, 4 contact holes, 5 agitators, 6 feed pipes, 7 return ducts, 8 discharge nozzles, 9 discharging tubes, 10 steam vents.
Detailed description of the invention
As shown in Figure 1-2 for a kind of elution device removing heavy metal in soil of this utility model, including housing 1, it is located at the agitator 5 of enclosure interior, housing is provided with the incubator 2 for cultivating acidophilic thiobacillus, incubator 2 is provided with the contact hole 4 contacted for soil with acidophilic thiobacillus, and described incubator is fixed on housing by support 3；It is provided with feed pipe 6 in lower housing portion, is provided with discharge nozzle 8 in housing side, be provided with the discharging tube 9 for discharging leacheate in discharge nozzle bottom, be additionally provided with return duct 7 in housing side；It is provided with steam vent 10, for getting rid of the gas in processing procedure at housing upper.
This apparatus main body part is high 2 meters, diameter 800 millimeters, stainless steel.The internal blender rotating speed of device is 85 revs/min.The microbial culture garden at device top, for UPVC material, is fixed by φ 8 garter spring and M8 countersunk head screw being installed on housing sidewall, incubator surface configuration 2 casting earth and microorganism species contact hole, being evenly distributed on ring duct orientation, pitch of holes 100mm, pipe is internal fills sulfur-bearing microbiological culture media.Feed pipe bore DN100 is positioned at bottom of device, and discharge nozzle bore DN100 is positioned in the middle part of device.
At this device initial operation stage, add acidophilic thiobacillus microbial inoculum and culture medium by steam vent to microbial culture garden, and to pending soil water filling, make soil moisture content be not less than 70%.Pretreated soil is injected from feed pipe, up and down reciprocatingly runs under the effect of agitator, after process completes, backfill after simple process discharged by discharge nozzle or use as him.Leacheate in soil can be emitted by discharge process by discharge nozzle bottom discharging tube.
By sulfuricum culture-medium in microbial culture garden, the fast enriching of acidophilic thiobacillus microbial inoculum is cultivated, quickly improve the Biomass in device, by the cultivation to acidophilic thiobacillus, the acidulous material discharged during utilizing its metabolic activity dissolves the heavy metal substances such as the lead zinc in polluted soil, it is transferred to heavy metals such as the lead zinc in polluted soil react in leacheate, it is achieved the purification of heavy metal in soil.Acidophilic thiobacillus microbial inoculum and metabolic activity product thereof contact with soil with the contact hole on incubator surface, it is achieved acidophilic thiobacillus finally realizes the removal to heavy metal in soil.
Purified up to standard after soil, 90% can be back to the reparation of contaminated site, and 10% is back to device charging aperture, utilize in processed rear soil rich in acidophilic thiobacillus again participate in the purified treatment of heavy metal in soil.
When after plant running a period of time, leacheate containing plurality of heavy metal ion is by the discharging tube periodic exhaustion of DN50 on device, according to reactor ruuning situation, within average 30-60 days, it is that the leacheate emissions passivation that will be enriched in heavy metal ion the cycle processes or recycles further.
Device of the present utility model utilizes microbial technique to process the heavy metal such as lead, zinc in contaminated soil, has low cost, the advantage that the feature of environmental protection is good.
Incubator is set in device, makes microorganism culturing simple and efficient, with entering beneficially its contacting with soil, improve the treatment effect of heavy metal, treatment effeciency can be effectively improved.
Reclaiming, contaminated soil is purified process, and it is technically characterized by comprising the steps as follows: the features such as with high content of technology, control simplicity, simple in construction.
Leacheate rich in heavy metal ion can discharge and reclaim metal contained therein, improves the utilization of resource and has certain economic worth.
