The specific embodiment
Below in conjunction with the accompanying drawing in the embodiment of the present invention, the technical scheme in the embodiment of the present invention is clearly and completely described.
According to Fig. 1 to 2, the invention provides a kind of contaminated soil original position repair system, comprise soil liquefaction unit and oxidative degradation unit.
The soil liquefaction unit comprises pressing mechanism and the seismic wave generating mechanism for generating water under high pressure, and pressing mechanism comprises two compression pumps (1) and two energy storage canisters (2), and tank mouth and the pressure delivery side of pump of energy storage canister pass through pipeline communication.The seismic wave generating mechanism comprises four arms that are communicated with the output of pressing mechanism (3), the arm end is connected with four output tips (4), the output tip is that sidewall is established foraminate tubule, be embedded in contaminated soil, arm is provided with High-speed Control valve (5), and the High-speed Control valve is conducting or the blocking state for switching arm under the control of computer (6).
During the arm conducting, water under high pressure penetrates from the aperture of output tip sidewall, and the soil liquefaction that the seismic wave that the water under high pressure abrupt release produces will be exported around tip is mud.
The quantity of compression pump, energy storage canister, arm, output tip, the length of output tip, the frequency of High-speed Control valve switching, can select flexibly according to the soil property of contaminated soil, the parameters such as the degree of depth of pollutant.
The oxidative degradation unit comprises self-priming water pump and the aeration tank, sedimentation basin, ozone pond, the dioxygen pond that arrange step by step, the input of self-priming water pump is embedded in contaminated soil near the output tip, pipeline at output is connected to aeration tank, and the input of pressing mechanism is connected with dioxygen pond pipeline.
In the time of the soil liquefaction cell operation, self-priming water pump is also started working, and will be evacuated in aeration tank with the water of pollutant.Sewage contacts with air in aeration tank, and the part pollutant evaporate in air, the oxidized degraded of part pollutant.Standing in the sedimentation basin of the sewage inflow next stage of processing through aeration tank, the silt in filtering sewage.Last sewage flows into further oxidative degradation in ozone pond and dioxygen pond.For saving water resource, force (forcing) pump draws water from the dioxygen pond, realizes recycling of water resource.
Have part water in water cycle process and lose because infiltrate depth of soils, in ozone pond one side, be provided with small pump, to moisturizing in the ozone pond.The dioxygen pond is connected with overflow pipe, when liquid level is too high in the dioxygen pond, in order to draining, maintains level stability in pond.
Ozone is provided with emulsifier unit in pond, can in water, generate a large amount of nano level bubbles, improves dissolved oxygen in water, strengthens the oxidative degradation effect.
The nano bubble water that emulsifier unit produces is extracted and is injected energy storage canister by compression pump, now the air in energy storage canister is compressed, when pressure reaches, when setting value respond to by pressure switch and the controlled pressure pump is out of service, and when pressure is less than lower limit, compression pump starts and moves.The main pipeline internal pressure be connected with energy storage canister equates with in energy storage canister, pressurizes and makes the energy storage canister energy storage, has been full of the high pressure nano air-bubble in main pipeline and arm.Produce signal (High-speed Control valve ON time is about 1 second) the generation seismic wave that the High-speed Control valve replaces transient switching under the control of computer control module, high pressure nano air-bubble moment is sent to the output tip, and discharge to contaminated soil, play the effect of vibrating liquefaction soil.
Output tip and oxidative degradation unit are arranged at the isolation canopy for the seal construction zone, and the pernicious gas evaporated in work progress is concentrated in the isolation canopy, unified discharge after harmless treatment.
A kind of contaminated soil original position repair system provided by the invention does not need the soil of mobile construction area while using, the soil liquefaction that the seismic wave produced by the water under high pressure abrupt release will be exported around tip is mud, the high pressure nano air-bubble fully contacts for the soil of mud with liquefaction, pollutant component in flushing oxidative degradation soil, thorough rehabilitating soil in position.Because being repairs in position, do not need large tracts of land to stir soil, can effectively reduce the volatilization of pollutant in soil, and construction area also is provided with the isolation canopy on every side, volatilization gas is collected, and unification purifies, discharge, can avoid the pollutant in soil to cause secondary pollution to air.
To the above-mentioned explanation of disclosed a kind of contaminated soil original position repair system embodiment, make professional and technical personnel in the field can realize or use the present invention.Multiple modification to these embodiment will be apparent for those skilled in the art, and General Principle as defined herein can be in the situation that do not break away from the spirit or scope of the present invention, realization in other embodiments.Therefore, the present invention will can not be restricted to these embodiment shown in this article, but will meet the widest scope consistent with principle disclosed herein and features of novelty.
