城市河流生物修复技术的研究进展

摘要

城市河流的污染严重影响市容和居住环境,已成为人们重点关注的环境问题之一.结合国内外河道治理现状,重点评述了微生物修复技术、植物修复技术、人工浮岛、人工湿地等生物修复技术的研究进展,并展望今后河道治理技术的重点发展方向.%Urban rivers pollution seriously affect city appearance and residential environment, which has become one of people focusing environmental issues. Combined with control status of rivers at home and abroad, the research pogress of microbial remediation technology, phy-toremediation technology, artificial floating island, artificial wetlands were reviewed, and the development direction of remediation technology was forecasted.
