The invention relates to a suspended sewage in-situ sampling device, a sampling method and sampling enrichment equipment. The suspended sewage in-situ sampling device comprises a main body, a connecting piece, a storage piece and a sampling piece, the main body is provided with a containing cavity, an opening communicated with the outside is formed in the cavity wall of the containing cavity, and the main body is used for suspending in a water body to be sampled; the connecting piece is connected to the main body, and the end part of the connecting piece extends outwards; the storage piece is arranged outside the main body; the sampling piece is contained in the containing cavity, a liquid inlet of the sampling piece is communicated with the opening, a liquid outlet of the sampling piece is communicated with an inlet of the storage piece, and the sampling piece is used for providing suction force so that a sample can enter the storage piece through the opening. The storage part is arranged outside the main body, so that the sample sampled by the sampling part can be stored outside the main body, the gravity of the main body cannot be changed, the height of the main body suspended in the to-be-sampled water body cannot be changed, the sampling points are at the same water level, and the reliability of the sampling result is improved.
本发明涉及一种悬浮式污水原位采样装置、采样方法及采样富集设备。悬浮式污水原位采样装置包括主体、连接件、存储件及采样件;主体构造有容纳腔,容纳腔的腔壁上具有与外界连通的开口,主体用于悬浮于待采样的水体中;连接件连接于主体,且连接件的端部向外延伸;存储件置于主体之外;采样件容设于容纳腔,采样件的进液口与开口连通,采样件的出液口与存储件的入口连通,采样件用于提供抽吸力,以使样本经由开口进入存储件。本申请通过存储件置于主体之外,从而通过采样件采样的样本,会存储于主体之外,不会改变主体的重力,使得主体悬浮于待采样的水体中的高度不会发生改变,从而使得采样点为同一水位,提高了采样结果的可靠性。
