Basic study on the absorption of oil and heavy metal, and biodegradation by peat

泥炭与水混合吸附重油的实验表明，泥炭对A型和C型重油的保留率分别为泥炭的4~5倍和6.5倍左右。圆柱柱试验表明，与其他吸油剂相比，泥炭在吸油过程中将煤油吸附到更高的位置，在石油解吸过程中将煤油保持在更高的位置。泥炭中A型和C型重油在25℃下生物降解70d，降解率分别为70%和30%。

The tests of heavy oil sorption by the peat mixed with water indicated that the peat is capable of retaining A-type and C-type heavy oil as much as 4 to 5 times and about 6.5 times the peat, respectively. The cylindrical column tests indicated that the peat soaks upkerosene to a higher position in an oil absorption process and retains kerosene at a higher position in an oil desorption process compared with other oil absorbents. The A-type and C-type heavy oil in the peat was biodegraded by 70% and 30% under 25℃for 70 days, respectively.
