| 摘要 |
The invention relates to a method of recycling contaminated soil so as to form a balanced non-contaminated soil with an increased water-holding capability. More particularly the invention combines two waste products, namely hydrocarbon-affected soil and activated sewage sludge, in order to create a useful non-waste product having high marketability. The combination, or mixing, of those waste products is done either by land farming and/or by composting. In the latter case the hydrocarbon-affected soil also acts as an insulating blanket over the compost, and that blanket itself is subsequently added into the compost after the curative process has dissipated the contaminants.
