中文摘要：

以老化的柴油污染土壤为供试土壤，以菌糠为调理剂，在模拟实验条件下，进行了为期90d的柴油污染土壤的堆肥研究，分别于堆肥进行的第30、60和90d采集土壤样品，分析土壤的总石油烃残留量和细菌与真菌的数量，探讨不同的菌糠投加比例、外源降解菌接种等因素对柴油污染土壤中石油烃污染物去除效率的影响，并对堆肥过程中堆体微生物数量的动态进行监测分析．研究结果表明，菌糠的添加显著促进了柴油污染土壤中石油烃的生物修复效率，经过90d的堆肥处理，总石油烃的去除率最高达73％．菌糠投加比例也对总石油烃去除率有明显的影响，随着菌糠与土壤体积比的提高，柴油污染土壤中总石油烃的去除率随之增加．外源高效降解菌的添加能显著提高柴油污染土壤中总石油烃污染物的去除率（p〈0．05）．

英文摘要：

The aged diesel fuel contaminated soil was taken as the test soil, and the mushroom residue was taken as the amendment agent to study the additive proportion of mushroom residual on the removal of diesel by the simulation experiment. The dynamic study and analysis of residual total petroleum hydrocarbons （TPHs） and the microbial populations was carried out at the day 30, 60 and 90 to explore the feasibility of composting taken the mushroom residues as the amendment agent and the microbiological degradation mechanisms of diesel fuel contaminated soil in the process of composting. Results showed that the mushroom residual significantly promoted the removal of TPHs in the diesel oil contaminated soil. After 90 days of composting treatment, the removal rate of diesel had reached to a maximum of 73%. The ratio of mushroom residue amendment agent to the diesel fuel contaminated soil had obvious effects on TPH removal rate. With the increase of the ratio of mushroom residue agent to the diesel fuel contaminated soil the removal rate of TPH in the soil increased. In addition, the inoculation of exogenous microorganisms can significantly improve the removal rate of diesel pollutants in the composting soil （p〈 0.05）.
