| Abstract: | The leaching slag pile discharged from the production of metal chrome and chrominum salts contains Cr~(6 ),which is permeated into underground and the ground water will be polluted when raining.The technology of permeation-proof underground concrete wall is adopted to prevent the ground water from Cr~(6 ) pollution.Through the supervision and test for more than 20 years,it is proved that this technology is practical and can be spreaded for use. |
