无气泡水样采集装置设计及在实验教学中的应用

Design and application of bubbleless water sampler in the experimental teaching

针对目前缺少适用于实验教学中的水样采集器现状,设计了一种应用于实验教学中的DO-1L型无气泡水样采集装置。该装置避免了采样时空气与水样的扰动,防止了采集的水样中混入气泡,同时把水样室与配重室做成一体,具有体积小、造价低、操作简便等优点,便于学生在野外环境中对自然水体采样。该装置适合于高校实验教学中野外水样的采集工作以及普通用途的水样采集,也可用于测定溶解氧等特殊要求水样的采集,可广泛应用于高等学校实验教学、环境监测部门和污水处理厂(站)的监测室等部门。

Since there was no suitable water sampler for experimental teaching,a bubbleless water sampler named DO-1L was designed which can be applied in the experimental teaching. This equipment was smaller,lower cost and easy operated,which was convenient to use in the outdoor natural sampling. It had three features as following： prohibition of air and water turbulence when sampling,prevention of bubble into the sample,water chamber and weight room were made as a whole. This equipment was suited both in the outdoor water sampling and common use for the experimental teaching of high school,also can be used to specific water sampling like waters collected for determination of dissolved oxygen. On the whole,the water sampler named DO- 1L can be widely used in the high school experimental teaching,environmental monitoring of departments and water quality monitoring of waste water treatment plants.
