油类废水采样器的优化研究

Study on Sampling and Monitoring Technology of Unevenly Distributed Pollutants in Water

一般说来,在水体中油的分布是很不均匀的,除少部分乳化状油较为均匀地存在于水体,大部分多分散浮于水面,若用普通采水器完全不能满足要求。因此,油类的环境监测采样要求必须单独使用采样器或专用采样器,并应定容或定面积采样,且不得在实验室再行分样。该研究根据永州市废水污染源的特点,设计制作出水中不均匀分布污染物油类的专用采样器,研究结果表明,其精密度和准确度方面明显优于普通采水器。

Generally speaking,in the medium oil water distribution is very uneven,in addition to a small number of emulsifying oil is relatively uniform consist in the water,much more dispersing floating on the surface of the water,if use normal mining water cannot completely meet the requirements. Oils,therefore,the environmental monitoring sampling requirements must be separate use sampler or sampler for special purpose,and shall be set for the sampling area,and shall not be any points in the laboratory sample. According to the characteristics of waste water pollution source industry in Yongzhou city,design and production of uneven distribution of pollutants in water oil sampler for special purpose,the research results show that the precision and accuracy obviously superior to ordinary water.
