Leachate from gangue is known as the main pollutants source to mining area soil and groundwater pollution. Long term leaching experiment are carried out to seek the long term effect on leachate chemistry of gangue under long term exposure to rainfall and atmosphere. Gangue from Xishan coal mine is used for long term dynamic leachate to analyze and compare the changes of the various metal ions in leachate...
Two different leachates of Chang'an landfill in Chendu were collected as the object of study. The components of organic pollutants in leachates were detected by combined GC-MS technique based on the general water quality analysis. Test results of study are as the follows: the type and nature of organic pollutant effect directly on leachate biodegradability. In high biodegradability (BOD5/CODCr = 0...
