(1) explore by near the geology of the underground water to chemical plant, determine Polluted area;
(2) again by Ground water Quality Survey, determine heavy metal lead point source in Groundwater;
(3) heavy metal lead point-source distribution figure in contrast Groundwater, finds heavily contaminated region, and at the heavily contaminated of underground waterA bite well is beaten in region, the well depth heavily contaminated underground water source contact-making surface that goes directly;
(4) lay same a bite well in light pollution sources region, the through light contaminated area of well depth underground water source contact-making surface;
(5) from the well of heavily contaminated region, extract underground water out with water pump in the heavy metal lead prosthetic device of ground, through repairingDevice directly passes in light contaminated area well after processing, and meanwhile, pours into the river after purifying, until gently polluteTill district's well is filled.
Described heavy metal lead prosthetic device is divided into 3rd district, and a district is that settling zone (2), 2nd district are electrolysis zone (3), threeDistrict is adsorption zone (4).
Settling zone, described Yi district (2) adds hydroxide (10) wherein, and plumbous reaction with hydroxide can form networkCompound, dissolves the sediment generating.
There is a rotation iron pan (6) in described Er district in electrolysis zone (3), be converted to chemical energy make electrolysis by electric energyNear electrode in groove, produce redox reaction, the lead ion in waste water and iron carry out redox reaction,Result produces novel substance.
Described San district is adsorption zone (4), places several property of modified rectorites (7), property of modified rectorite in adsorption zone (4)Can substantially adsorb the lead in lead waste water.
Operation principle of the present invention: underground water is passed into settling zone, and adds hydroxide in settling zone, plumbous withHydroxide reaction can form white precipitate, and the sediment generating is dissolved; Then lead waste water enters electricityXie Qu, places a rotation iron pan in electrolysis zone, be converted to chemical energy make near the electrode in electrolytic cell by electric energyProduce redox reaction, the lead ion in waste water and iron carry out redox reaction, and result produces novel substance;Then the lead waste water after electrolysis enters into adsorption zone, several property of modified rectorites in adsorption zone, property of modified rectoriteCan substantially adsorb the lead in lead waste water, finally make purification of waste water. After prosthetic device is processed, directly pass into lightIn Polluted area well, meanwhile, pour into the river after purifying, until light Polluted area well is filled.
Application process of the present invention is:
(1) explore by near the geology of the underground water to chemical plant, determine Polluted area;
(2) again by Ground water Quality Survey, determine heavy metal lead point source in Groundwater;
(3) heavy metal lead point-source distribution figure in contrast Groundwater, finds heavily contaminated region, and at the heavily contaminated of underground waterA bite well is beaten in region, the well depth heavily contaminated underground water source contact-making surface that goes directly;
(4) lay same a bite well in light pollution sources region, the through light contaminated area of well depth underground water source contact-making surface;
(5) from the well of heavily contaminated region, extract underground water out with water pump in the heavy metal lead prosthetic device of ground, describedHeavy metal lead prosthetic device is divided into 3rd district, and a district is that settling zone (2), 2nd district are that electrolysis zone (3), 3rd district are absorptionDistrict (4), arranged in series successively; The described underground water of extracting out from the well of heavily contaminated region enters a settling zone, district (2),And add wherein hydroxide (10), lead ion to react meeting generation white precipitate with hydroxide, make to generateSediment dissolve; Water outlet enters two electrolysis zones, district (3), in electrolysis zone, described Er district (3), has one to revolveTurn iron pan (6), be converted to chemical energy by electric energy and make to produce redox reaction near the electrode in electrolytic cell,Be that lead ion and iron in waste water carries out redox reaction; Water outlet enters three district's adsorption zones (4) again, describedIn adsorption zone (4), place property of modified rectorite, the lead in the adsorbable water of rectorite; After prosthetic device is processed, directlyPass in light contaminated area well, meanwhile, pour into the river after purifying, until light contaminated area well is filled.
The significant advantage that the present invention has is:
(1) this device adopts electrolysis, and the cycle is short, less energy consumption, and operating cost is low.
(2) this device utilizes property of modified rectorite absorption, aboundresources, and method of modifying is simple, avoids secondary pollution.
