- 摘要：研究了现场中试条件下芦苇湿地处理钻井泥浆的可行性及钻井泥浆对土壤和芦苇等湿地介质的影响.研究结果表明:在7个月的运行期内,单位面积钻井泥浆施入量为5kgm2,20kgm2和40kgm2的芦苇湿地对矿物油的迁移降解率分别为:75%-85%,78%-90%和65%-90%;钻井泥浆中的矿物油对湿地土壤的污染基本局限于表层,对深层土壤的污染趋势并不明显,一般40cm以下矿物油含量已低于对照区表层土的背景值;钻井泥浆能增加芦苇的生物量,对芦苇品质指
- Abstract：The feasibilily of driling mud treatment with read wetland and the impact of drilling mud on soil and read were studied. The results showed that the amount of drilling mud were 5kg/m2, 20kg/m2, 40kg/m2 and the mineral oil purificative ratios were 75%-85%, 78%-90% and 65%-90%, respectively. The results also showed that the surface soil, was seriously polluted. In general, the mineral oil content in the soiled depth of 40cm deep is lower than the background value.The drilling mud stimulates the growth of reed and the drilling mud has litter impact on reed quality.
