摘　　要：盐源干海井井水矿化度较高,固体杂质多,长期观测脱气装置易产生堵塞、流量不稳定等问题,严重影响数据观测质量。在干海井曾试验采用自吸式、电动溅落式、电动鼓泡式等3种不同类型的脱气装置,通过对比由不同脱气装置所得气氡浓度观测数据并分析3种脱气装置的优缺点后发现,采用电动鼓泡式脱气装置气氡浓度观测数据稳定性好,干扰少,较适合干海井观测条件。在现用电动鼓泡式脱气装置的基础上提出改进建议,以更好适应干海井含大量杂质的观测环境,提高观测质量。The mineralization degree of well water in the ganhai well of Yunnan is relatively high,and solid impurities are abundant.Long-term observation of degassing device can easily lead to problems such as blockage and unstable flow rates,severely impacting the quality of data observation.Three different types of degassing device have been experimentally used in the ganhai well,including a self-suction type,an electric splash type,and an electric bubble type.By comparing the radon concentration data obtained from different degassing devices and analyzing the advantages and disadvantages of the three types,it was found that the electric bubble type degassing device exhibits good stability in radon concentration observation data and less interference.It is more suitable for the observation conditions of ganhai well.Based on the currently used electric bubble type degassing device,suggestions for improvement are proposed to better adapt to the observation environment of the ganhai well containing a large number of impurities,thereby enhancing the quality of observation.
