Abstract
The invention discloses a kind of contaminated soil magnetic and help electro reclamation device.By the effect in extra electric field and magnetic field, make the polluter in soil accelerate to be enriched in regulation region, reach the object of cleaning soil.Apparatus of the present invention comprise electrode solution adding tube, positive plate, treatment region, cathode column, electrode chamber, magnet, shell, electrode solution delivery pipe.Contaminated soil is placed in treatment region, and electrode solution enters electrode chamber district through piping, and the pollutant then in the soil under action earth of additional electromagnetic field moves rapidly, improves the concentration of local pollution thing.Structure of the present invention is simple, construction cost is low, be easy to operation, and the degraded that can achieve multiple pollutant in soil is removed.
Description
Technical field
the invention belongs to contaminated soil processing technology field, specifically, it relates to a kind of contaminated soil magnetic and helps electro reclamation device, for the treatment of the heavy metal in contaminated soil or organic pollution.
Background technology
Soil is as the typical combined pollution medium of one, and its pollution has cumulative bad, hysteresis quality, disguise and irreversibility, and extremely difficulty carries out recovering and processing.Pollutant in soil can enter soil by number of ways, the character of soil, composition and proterties etc. are changed, the natural dynamic equilibrium of spoiled soil, thus cause soil natural functional disturbance, soil quality to worsen, affect the growing of crop, the seed output and quality decline of product, produce certain environmental effect, and by food chain, biological and the mankind are threatened.
At present, domestic and international scientific research personnel has developed multiple soil treatment recovery technique, although achieve certain achievement, but single recovery technique has a definite limitation in the scope of application and economy, the complex repairation technology of being got up by multiple methods combining and relevant apparatus thereof become the focus of research.Electric repairing technique utilizes extra electric field to form electric-force gradient in soil both sides, and pollutant in soil directional migration under electric field action is brought to ate electrode, thus clean contaminated soil.And magnetic field can have an impact to the mechanical-physical of soil and pollutant and electrochemical properties.Electric repairing technique combines with magnetic treatment technique by this invention, utilizes two kinds of physical fields to provide energy to accelerate the removal of pollutant in soil.
Summary of the invention
The object of the present invention is to provide the contaminated soil magnetic that a kind of structure is simple, construction cost is low, be easy to operate to help electro reclamation device, the degraded being intended to realize multiple pollutant in soil is removed.
For achieving the above object, by the following technical solutions: a kind of contaminated soil magnetic helps electro reclamation device, comprising: electrode solution adding tube, positive plate, treatment region, cathode column, electrode chamber, magnet, shell, electrode solution delivery pipe; Described device is uncovered shape, and outermost layer is shell; Described electrode chamber is positioned at enclosure, and described electrode solution adding tube is positioned at device top, stretches in electrode chamber; Described positive plate is located at electrode chamber inside; The region of electrode chamber inside is treatment region; Described cathode column is positioned at the center for the treatment of region; Described magnet is embedded between electrode chamber and shell; The electrode solution delivery pipe stretched out from electrode chamber is provided with in device bottom.
The inwall of described electrode chamber 5 is porous plate.

Detailed description of the invention
The present invention is described further to contrast the drawings and specific embodiments below.
As illustrated in fig. 1 and 2, this device comprises electrode solution adding tube 1, positive plate 2, treatment region 3, cathode column 4, electrode chamber 5, magnet 6, shell 7, electrode solution delivery pipe 8.Device is uncovered cylindrical, and outermost layer is shell 7.Electrode chamber 5 is positioned at enclosure, and electrode solution adding tube 1 is positioned at device top, stretches in electrode chamber 5.It is inner that positive plate 2 is located at electrode chamber 5, and the region of electrode chamber 5 inside is treatment region 3.Cathode column 4 is positioned at the center for the treatment of region 3.Magnet 6 is inlaid with between electrode chamber 5 and shell 7.The electrode solution delivery pipe 8 stretched out from electrode chamber 5 is provided with in device bottom.The inwall of electrode chamber 5 contact pairs district 3 contact is porous plate.It is 0.5 ~ 1.5V/cm that device is suitable for potential gradient.
Device also can be uncovered rectangular-shaped.
When using this device, first contaminated soil compaction in layers is placed in treatment region; Entered in electrode chamber by electrode solution adding tube as electrode solution using running water or electrolyte solution, and enter treatment region by porous internal walls; Then with wire, positive plate and cathode column are connected to the both positive and negative polarity of dc source, adjustment potential gradient is 0.5 ~ 1.5V/cm; Under electromagnetic field effect, plant running 24h; After reaction terminates, electrode solution is discharged by electrode solution delivery pipe.
Although the present invention with preferred embodiment openly as above; but embodiment and accompanying drawing are not for limiting the present invention, being anyly familiar with this those skilled in the art, without departing from the spirit and scope of the invention; can make various changes or retouch from working as, but same within protection scope of the present invention.What therefore protection scope of the present invention should define with the claims of the application is as the criterion.
