Embodiment 1

[0044] Embodiment 1: A water sample collection system for sampling from surface water, spring water or underground underground rivers.

[0045] like figure 1 Shown, the water sample collection system of the present invention is that the input port of the self-priming pump 2 is connected to the water inlet pipe or the spherical filter 1 through the pipeline, and the outlet port of the self-priming pump 2 is connected with the tee 5 through the pipeline, and at the tee 5 The upper port is connected to two series-connected expansion tube filters 7 through pipelines, the upper port of the upper expansion tube filter 7 is connected to the input port of the mass stabilizer 3 through pipelines, and the bypass port of the tee 5 is connected to the diversion control valve 4. The upper output port of the mass stabilizer 3 is connected to the split combined sampling bottle 6 through a pipeline.

[0046] The expansion tube filter 7 is an optional part in the water sample collection syste...

Embodiment 2

[0060] A water sample collection method for sampling from surface water, spring water or underground rivers, including the following steps:

[0061] 1. Construction of the water sample collection system: first use a glass bottle to take a small amount of surface water, spring water or water in underground underground rivers to be sampled, observe the water body and water quality, if the water body is clear, connect the water inlet pipe 8, self-priming pump 2, three Through 5, the diversion control valve 4 and the mass stabilizer 3 are assembled to construct a water sample collection system. If the water body contains firewood-like floating objects, assemble the spherical filter 1, self-priming pump 2, tee 5, diversion control valve 4 and mass stabilizer 3 to build a water sample collection system. If there are both firewood floating matter and solid particle suspended matter in the water, the spherical filter 1, self-priming pump 2, tee 5, diversion control valve 4, quality st...

Abstract

The invention relates to a water sample collection system and a water sample collection method for surface water and spring water. The water sample collection system is connected to a water inlet pipe or a spherical filter at the input port of a self-priming pump through a pipeline. The output port of the suction pump is connected with a tee through a pipeline, the upper port of the tee is connected with the input port of the mass stabilizer through a pipeline, and the bypass port of the tee is connected with a diversion control valve, and the The upper output port of the upper end is connected to the split combined sampling bottle through a pipeline. The invention can effectively filter solids such as firewood and plastic sheets in water and solid granular substances in the water body. When the sample enters the water sample collection system, it is in a state of pressure and oxygen isolation. The collected water sample is in a relatively dynamic state. In a balanced state, through the water sample collection system, there is little disturbance, which reduces the probability of volatile substances escaping, thus solving the problem of sample distortion caused by the direct filling method of collecting water samples containing environmentally sensitive substances.

Description

technical field [0001] The invention relates to a water sample sampling device and a collection method for collecting volatile substances and oxygen-sensitive substances, in particular to a water sample collection system and a water sample collection method for surface water and spring water. Background technique [0002] At present, for the collection of water samples of surface water and spring water containing volatile substances and oxygen-sensitive substances, they are usually filled directly with sampling bottles. It enters the bottle in the form of a "thin stream", and the water flow is directly exposed to the air. On the one hand, the volatile substances in the water will be lost. On the other hand, the oxygen-sensitive substances in the water are easily oxidized by contact with the air. These factors will cause sample distortion ; Second, in the process of water samples entering the bottle, on the one hand, the liquid surface is always in contact with the air, that ...
