Abstract
The utility model discloses an in-situ remediation device of chromium-polluted ground water. The in-situ remediation device comprises a grid tank, a regulation tank and an adsorption treatment device, wherein a grid is arranged in the grid tank, a wastewater inlet is arranged on the tank wall above the grid, a water outlet on the tank wall below the grid is connected with a water inlet of the regulation tank, the water outlet of the regulation tank is connected with the water inlet of the adsorption treatment device, and the adsorption treatment device sequentially comprises a quartz sand layer, a polluted soil layer, a PRB (permeable reactive barrier) medium layer and the quartz sand layer from the water inlet to the water outlet. The in-situ remediation device has the advantages of simple structure and convenience in operation, and can be used for quickly and efficiently treating the polluted soil in a chromium-polluted place.
Description
Technical field
The utility model relates to a kind of contaminated soil treatment unit, relates in particular to a kind of pollution of chromium underground water in-situ repairing device.
Background technology
Chromium is a kind of typical murder by poisoning element, is regarded as the important research object of environmental geochemistry for a long time.The different differences that directly cause its toxicity of the chemical form of chromium and valence state in the environment.Under general pollution level, the animals and plants and the microorganism that live in the soil all can show the symptom of being injured accordingly.When human body directly or indirectly contacted the chromium pollutant of different concns, acute and chronic intoxicating phenomenon can appear.
In the prior art, pollution of chromium improvement method mainly comprises physics method, chemical method and biological process etc.These methods exist all that abatement equipment is huge, cost is high, inefficient problem.
The utility model content
The purpose of this utility model provide a kind of rapidly and efficiently, simple to operate, pollution of chromium underground water in-situ repairing device that cost is low.
The purpose of this utility model is achieved through the following technical solutions:
Pollution of chromium underground water in-situ repairing device of the present utility model comprises grating tank, equalizing tank and adsorption treatment device;
Be provided with grid in the described grating tank, the pool wall of described grid top is provided with water intake, water outlet on the pool wall of described grid below is connected with the water-in of described equalizing tank, the water outlet of described equalizing tank is connected with the water-in of described adsorption treatment device, and described adsorption treatment device is followed successively by from water-in to water outlet: quartz sand layer, contaminated soil layer, PRB medium layer, quartz sand layer.
The technical scheme that is provided by above-mentioned the utility model as can be seen, the pollution of chromium underground water in-situ repairing device that the utility model embodiment provides, simple in structure, easy to operate, processing pollution of chromium place contaminated soil that can be rapidly and efficiently.
Description of drawings
The structural representation of the pollution of chromium underground water in-situ repairing device that Fig. 1 provides for the utility model embodiment.
Among the figure: 1, grid, 2, pump, 3, pump.
Embodiment
To be described in further detail the utility model embodiment below.
Pollution of chromium underground water in-situ repairing device of the present utility model, its preferable embodiment is:
Comprise grating tank, equalizing tank and adsorption treatment device;
Be provided with grid in the described grating tank, the pool wall of described grid top is provided with water intake, water outlet on the pool wall of described grid below is connected with the water-in of described equalizing tank, the water outlet of described equalizing tank is connected with the water-in of described adsorption treatment device, and described adsorption treatment device is followed successively by from water-in to water outlet: quartz sand layer, contaminated soil layer, PRB(permeable reactive barrier) medium layer, quartz sand layer.
Be respectively equipped with pump on the connecting pipeline of the connecting pipeline of described grating tank and described equalizing tank and described equalizing tank and described adsorption treatment device.
Use the utility model, grating tank stops the suspended solids in the water inlet and holds back, equalizing tank can equilibrium be regulated the sewage quantity of the entire sewage treatment system of flowing through, the adjusting of carrying out the water yield and water quality in equalizing tank is stable, carrying out PRB through the adsorption treatment device again handles, have efficient, cheap, be easy to get, do not produce secondary pollution, applicable to advantages such as original position reparations, the pollution of chromium groundwater treatment efficient of 5mg/L can be reached 100%.
The treating processes of specific embodiment is:
Actual waste water or water distribution after grating tank, after equalizing tank is stable, in the suction adsorption treatment device, are passed through the adsorption of PRB medium again, realize the phreatic reparation of cadmium pollution.
Wherein, described PRB media applications can be water proof funnel-water guide gate-type PRB in actual underground water original position reparation is used the time.
Wherein, industrial activited carbon and the quartz sand mixed fillers of PRB medium after sulfuric acid modified.
Wherein, the preparation of modified industry gac is: industrial activited carbon is cleaned to inclusion-free, at 2%H
2SO
4In soak 24h in 25 ℃, stable to scavenging solution pH with washed with de-ionized water again, with (110 ℃) oven dry in baking oven of the industrial activited carbon after the modification, be placed in the moisture eliminator standby after room temperature cools at last.
Wherein, the contaminated soil layer can be experimental configuration, or actual contaminated soil.
The above; it only is the preferable embodiment of the utility model; but protection domain of the present utility model is not limited thereto; anyly be familiar with those skilled in the art in the technical scope that the utility model discloses; the variation that can expect easily or replacement all should be encompassed within the protection domain of the present utility model.Therefore, protection domain of the present utility model should be as the criterion with the protection domain of claims.
