The soil pillar mimetic analysis on the changing characteristics of the leaching liquid pollution component of the daily life garbage -Taking the Beitiantang dumping grounds in Beijing City as example;

Malic acid leaching investigation on thallium-containing pyrite deposit;

Effect of sewage sludge compost and its Dissolved Organic Matter (DOM) on desorption and leaching of Fluoranthene from soil;

In order to investigate the leaching behavior of trace elements from oil shale piled at the southern Fushun city and its effects on the surrounding water, dynamic experiment of leaching oil shale samples from the West Open Pit and the West Dumping Site, Fushun, have been undertaken at 4.

The influence to release of thallium from slag on time of leaching,pH of leaching liquid,size of slag and speeds of leaching are inspected.

Since the fluctuation of quality and quantity, and full of harmful pollutants, leachates pose pollution to the environment around the landfill, especially to soil and groundwater.

The laboratory column leaching tests and a numerical model for pollutants migration in the aquifer were done, some pollution control plans were proposed finally and their effects were simulated and discussed.
