Description
技术领域technical field
本实用新型涉及一种上覆水与沉积物间隙水一体采集装置。The utility model relates to an integrated collection device for overlying water and sediment interstitial water.
背景技术Background technique
对不同水体环境的调查一直是生态学、环境科学乃至全球气候变化研究的重要内容，作为研究水体环境的必要手段，分层采集上覆水和水下沉积物间隙水，对于分析水环境质量状况，监测溶存温室气体浓度有着重要的现实意义。The investigation of different water body environments has always been an important content in the study of ecology, environmental science and even global climate change. As a necessary means to study the water body environment, the layered collection of overlying water and interstitial water from underwater sediments is essential for analyzing the quality of the water environment. Monitoring the concentration of dissolved greenhouse gases has important practical significance.
传统的上覆水采集装置如：有机玻璃采水器、卡盖式采水器、杆持式采水器、多通道水样采集器等都不同程度存在水样采集过程搅动大、难以分层采集水样、无法密封水样，影响溶解性气体测定、采样繁琐复杂等问题；传统的间隙水采样方法如：离心分离法、整柱压榨法、透析膜法（Peeper）等，离心法通过沉积物直接离心分离获得，对沉积物形态完整性造成破坏（整柱压榨法类似），透析膜法则装置造价昂贵、容易损坏且间隙水采集量较少。此外，目前此类采样装置多将上覆水采集和间隙水采集分离，上覆水和间隙水的采集难以同步进行，也难以在同一采样点开展两种水样的采集任务，影响样品精度。因此，亟需一种上覆水及沉积物间隙水一体采集装置，确保采样的准确高效。Traditional overlying water collection devices such as plexiglass water collectors, card-type water collectors, pole-mounted water collectors, multi-channel water sample collectors, etc. have different degrees of agitation during the water sample collection process and difficulty in layered collection Water samples, unable to seal water samples, affecting the determination of dissolved gases, complicated sampling and other issues; traditional interstitial water sampling methods such as: centrifugal separation, whole column pressing, dialysis membrane (Peeper), etc., centrifugation through the sediment Obtained by direct centrifugation, which will damage the morphological integrity of the sediment (similar to the whole column pressing method), while the dialysis membrane method is expensive, easy to damage, and the amount of interstitial water collected is small. In addition, most of the current sampling devices separate the collection of overlying water and interstitial water. It is difficult to collect overlying water and interstitial water simultaneously, and it is also difficult to collect two kinds of water samples at the same sampling point, which affects the accuracy of samples. Therefore, there is an urgent need for an integrated collection device for overlying water and sediment interstitial water to ensure accurate and efficient sampling.
