植物修复技术在近海污染治理中的研究与应用

Study on the application of phytoremediation technology to the treatment of wastewater in the coastal sea

对国内外有关近海污染的植物修复技术研究进展进行综述,简述植物修复的6种作用机理,阐明植物修复对海水养殖富营养化、石油等有机物污染、赤潮、近海重金属污染以及污水净化的作用。最后指出应用植物修复技术治理近海污染具有以下优点:①对人类和海洋环境副作用小、生态风险小,易于为人们接受;②易于后处理,不会形成二次污染,很少有废物和排放物,遗留问题少;③具有一定的生态景观效应;④生物量大。

The phytoremediation technology applied to coastal water treatment in China and abroad is reviewed. Six mechanisms of phytoremediation are outlined. The phytoremediation technology is useful in alleviating eutrophication caused by marine cultivation, reducing pollution of oil and other organic substances, controlling red tide and pollution of heavy metal, and purifying wastewater. The advantages of the phytoremediation technology in coastal pollution abatement includes: 1. it is acceptable to people because of its slight side effect for human and marine environment and its small ecological risk; 2. its post treatment is easy, and with little wastes, emissions, and problems left, it won't cause secondary pollution; 3. it contributes to ecological landscaping; 4. its output is large.
