摘要:

江河水污染治理一个首要环节是检测和分析污染物,例如微生物、油污、化学污染物等,从而确定污染源和找出治理措施。目前对微米尺度污染物的快速检测仍然没有通用成熟的技术。我们采用点光源4维数字全息技术对珠江广州市河段的典型水体进行检测,发现原生动物放射虫的矿化骨架、轮虫和微油滴等。测得桡足动物和轮虫的游动速度分别为280微米每秒和100微米每秒。我们指出高密度的微油滴的存在对自然环境的危害极为严重。

A key step in the restoration of rivers and lakes is to identify the major pollutants such as mi-cro-organisms, oil, and of course chemicals, so that the source can be identified and remedies can be devised. A general method for rapidly monitoring pollutants of micrometer scale is still lacking. We use 4D digital holographic microscope with point laser source to study the typical water sample taking from Pearl River within Guangzhou. Copepods, rotifer, mineralized skeleton of radiolarian protozoa, dead cells, micro-oil drops are identified. The speeds of copepod and rotifer are measured to be 280 and 100 micrometer per second. The hazard of high-density micro-oil drops is noted.
