| titleOfInvention | Remediation and dewatering of dredged slurry and mine tailing with the vacuum method and electrokinetic phenomenon(Vacuum-electrokinetic dewatering and remediatin method) |
| abstract | The present invention combines vacuum drainage techniques and electrokinetic phenomena for the removal of contaminants and rapid dewatering in heavy water slurry and tailings contaminated with heavy metals.n n n Recently, large-scale dredging projects are being carried out nationally to remove coastal landfills and polluted coastal sediments and improve seawater quality. These dredged soils are contaminated for more than a few decades by organic matter, nutrients, heavy metals and harmful chemicals contained in industrial wastewater, domestic sewage, leachate from waste treatment plants, and rainfall runoff in urban and rural areas. There is this. In addition, the tailings generated as a by-product after recovering useful metals by beneficiation remain heavy metals and other harmful substances, and contain a large amount of fines in a high water content state to remove moisture to reduce volume. High cost and effort are requiredn n n This method combines vacuum drainage technique and electrokinetic phenomena using the ground electrochemical properties to dredged soils and tailings, which are contaminated with heavy metals, to promote the purification and rapid dehydration of heavy metals. The characteristics of the present invention using the vacuum drainage technique and the electrokinetic phenomena are i) desorb heavy metals from the granules using H + ions generated by electrolysis at the anode (+), and desorb the heavy metals by electrostatic attraction. Due to ion migration and electro-osmotic and vacuum drainage, the heavy metals are removed by the negative-electrode drainage; ii) accelerated sedimentation and dewatering of high content dredged soil and tailings using electrophoresis, electroosmotic and vacuum drainage; iii) vacuum extraction of OH - ions generated by electrolysis at the negative electrode (-) to inhibit the inflow into the slurry to prevent hydroxide precipitation of heavy metals occurring near the negative electrode (-); Iii) layered intersections of anode (+) and cathode (-) during landfill of dredged soil; Iii) It is characterized by the development of connecting clamp which is connected with electrode tube and drain tube and electrode tube which simultaneously serve as electrode and horizontal drain. |
