富营养化水体的物理-生态修复技术发展综述

Remediation of Eutrophication by a Physical-Ecological Approach

随着人口的急剧膨胀和工农业的迅速发展,大量生活污水和工农业废水所引起的水体富营养化已引起人们的普遍关注,而水体物理-生态修复技术是目前一条创新的治理技术路线。物理-生态修复技术是利用培育的植物(包括浮游植物如藻类和大型水生植物等)、培养和接种的微生物、水生动物(如浮游动物水蚤和螺蚌鱼类等)的生命活动对水中污染物进行转移、转化及降解,从而使水体得到净化的技术。通过对该技术的发展综述,强调了人与自然和谐相处的治污思路对水生生态系统快速恢复的重大现实意义。

With rapid development of industry and growth of population, water eutrophication caused by daily sewerage discharge and non - point pollution has been drawing great attention. It is described in the present review paper that physical - ecological recovery technology is a new approach in controlling water eutrophication. It is to use the life activities of plants, cultivated microorganisms and aquatic to transfer in deducing the pollution oi water. It is considered that the described approach may be regarded as a new and creative technology to purify polluted water at present.
