The invention relates to an aeration tank gas sampling device and a use method thereof, a bottom opening baffle plate of the device is arranged at the bottom of the sampling device and is connected with a spring and a connecting rod, two ends of the spring are respectively connected with the bottom of a floating body and the bottom opening baffle plate, and the connecting rod penetrates through the floating body and a sampling cylinder to realize vertical movement; the sampling barrel and the floating body are fixed into a whole, the floating body is a light material plate so that the sampler can float on the surface of water, and an air bag is placed in the sampling barrel. The top cover is arranged on the sampling cylinder body, is in a convex shape on the whole and can be lifted up or pressed down. The temperature and pressure gauge is connected with the air bag and can read the temperature and pressure of the sample in the air bag; the air extracting pump is connected with the air bag and is used for extracting air in the air bag and outputting the air to the sampling bag. The sampling device is fixed on the edge of the sampling pool. The device is used for collecting the gas generated by the biochemical reaction of the aeration tank, and can accurately and quantitatively obtain the gas emission flux. The influence of unfavorable working conditions such as unstable sampling parameters and high foam of the aeration tank caused by water surface stirring of the aeration tank on a sampling result is avoided.

    本发明涉及一种曝气池气体采样装置及其使用方法,该装置的底口挡板设置于采样装置底部,与弹簧和连杆相连接,弹簧两端分别与浮体底部和底口挡板相连,连杆贯穿浮体和采样筒体,实现上下移动;采样筒体和浮体固定为一体,浮体为轻质材料板便于使采样器漂浮于水体表面,采样筒体内部放置了气袋。顶盖设置在采样筒体上,整体呈凸字型,可提起或者下压。温度压力表连接气袋可读取气袋内样品的温度和气压;抽气泵连接气袋,用于抽取气袋内气体并输出给采样袋。采样装置固定在采样池边缘。本发明用于收集曝气池生化反应产生的气体,并可准确定量获得气体排放通量。避免了曝气池水面搅动引起的采样参数不稳定、曝气池高泡沫等不利工况的对采样结果的影响。
