Description
Technical field
The present invention relates to pollution amelioration heavy-metal contaminated soil technologies in situ.
Background technique
Contaminated soil remediation is at home and abroad increasingly taken seriously, at abroad, some technologies come into engineering mimoir and
Application stage.Common soil restoring technology mainly has chemical leaching technology, electric repairing technique, PRB technology etc..Due to soil
The differences such as composition, pollutant type, property are single to repair especially in the simultaneous combined pollution of different pollutants
Recovering technology is often difficult to reach reparation target, and therefore, the combined application of different recovery techniques is increasingly taken seriously.
EK-PRB combined remediation technology is a kind of novel, the environmentally protective soil restoring technology risen in recent years, main
If electric repairing technique is combined common repairing polluted soil with permeability response wall technology.The technology combines two kinds
The advantage of recovery technique, by the higher heavy metal of toxicity and organic substance (such as Cr (VI), TCE, PCE etc.) electric power make its to
Electrode tip is mobile, reacts polluter with the filling substrate of permeability response within the walls, is degraded into the lower low-valent metal of toxicity
Ion and organic matter, can not only restoration of soil polluted by heavy metal can be with repairing organic polluted soil, or even to low-permeability
Contaminated soil has preferable repairing effect, and is influenced by extraneous factor relatively small, avoids environment is added into soil not friendly
Good type substance, rehabilitation cost want much lower compared with other methods.
EK-PRB combined remediation technology is as an emerging efficient based technique for in-situ remediation, although Principles are relatively simple
It is single, but existing EK-PRB joint prosthetic device is mostly assembled in situ, takes up an area larger, mobile inconvenience.
Summary of the invention
The technical problem to be solved in the present invention is to provide a kind of EK-PRB dresses of reparation combined contamination soil being moved easily
It sets.
In order to solve the above-mentioned technical problem, a kind of the technical solution adopted by the present invention are as follows: packaged type reparation combined pollution
The EK-PRB device of soil, including electrodynamics devices, soil chamber and PRB device, electrodynamics devices include electrode plate with
And DC power supply, electrode plate height are higher by 3~5cm of soil chamber, electrode plate is made of graphite, further includes an annular reaction
Slot is provided with several slots being disposed radially in reactive tank inner cavity, is arranged at intervals with cathode plate and anode plate in slot,
Soil chamber is formed between adjacent anode plate and cathode plate；PRB device is arranged between cathode plate and soil chamber；Below soil chamber
It is laid with impermeable layer, top is then provided with application of anti-leakage layers；DC power supply is electrode plate power supply.
Further, the shortest distance between cathode plate and anode plate is greater than 30cm.
Further, thickness of electrode is 1~3cm, and the direct current electricity output of DC power supply can guarantee the electricity being applied on soil
Press gradient >=10V/m.
Further, anode plate and cathode plate are all circumferentially uniformly arranged in reactive tank.
Further, the PRB device includes zeolite, cast-iron scrap, attapulgite and or active carbon.
Further, it is also equipped with PRB device around anode plate, combines to form permeable reaction again with graphite electrode
Composite electrode.
From above-mentioned technical proposal it can be seen that the invention has the following advantages that using annular design, anode plate two sides is all
Against one piece of cathode plate, such anode plate two sides can react production, compared with one piece of anode plate and cathode plate only is arranged significantly
Improve electrolytic efficiency；Several anode plates are provided with, it can be achieved that multiple anode plate simultaneous reactions, yield are obviously improved；
Furthermore, it is possible to select the quantity of electrode plate according to live needs, applicability is improved；Overall structure is simple, the design of annular reaction slot
