Water body collection system and sampling method

Abstract

The invention discloses a water body collection system and a sampling method, and belongs to the technical field of water quality sampling. The collection system comprises a sampler, a water sample conveying power source, water sample storage equipment, conveying pipelines and a controller; the sampler is provided with a sampling cavity with the end communicated with the outside, and the end, communicated with the outside, of the sampling cavity is soaked in a natural water body; the liquid inlet end of the water sample conveying power source is communicated with the sampling cavity, and the water sample storage equipment is communicated with the water sample conveying power source; the conveying pipelines are arranged between the sampler and the water sample conveying power source and between the water sample conveying power source and the water sample storage equipment; and the controller is electrically connected with the sampler and the water sample conveying power source. The communicating end of the sampling cavity of the sampler and the natural water body is closed, and the water sample conveying power source discharges a water sample in the sampling cavity of the sampler by a preset amount and then stops working, so that the water sample can be prevented from being retained in the sampling cavity of the water sampler, and the breeding speed of microorganisms in the water sampler is reduced.

Description

technical field [0001] The invention belongs to the technical field of water quality sampling, in particular to a water body collection system and a sampling method. Background technique [0002] The existing water body collection system soaks the water body sampler in water, and then collects a predetermined amount of water samples at predetermined intervals. When the water body collection system is not started, the inner cavity of the water body sampler soaked in water also retains a predetermined amount of water. sample, and the fluidity of the water sample in the water sampler is lower than that of the natural water body, so the microbial growth rate in the water sampler is greater than the microbial growth rate in the natural water body, and each test is based on the last test On the basis of superimposing the microorganisms that grow in the water sampler, the detection value is higher than the actual water pollution and microbial value, and the detection error graduall...

[0002] The existing water body collection system soaks the water body sampler in water, and then collects a predetermined amount of water samples at predetermined intervals. When the water body collection system is not started, the inner cavity of the water body sampler soaked in water also retains a predetermined amount of water. sample, and the fluidity of the water sample in the water sampler is lower than that of the natural water body, so the microbial growth rate in the water sampler is greater than the microbial growth rate in the natural water body, and each test is based on the last test The microbes that grow in the water sampler are superimposed on the basis of the water sample, which leads to the detection value being higher than the actual water pollution and microbial value, and the detection error gradually increases, which eventually leads to the problem of misjudgment
