The number of the detection boxes 300 is N, N is a positive integer, the pipeline is provided with N+1 pipeline connectors 220, the pipeline comprises a main pipe 210 and N water diversion pipes 230, and each water diversion pipe 230 is connected with one detection box 300. When parallel experiments need to be carried out, N is more than or equal to 2. In fig. 1, 2 water diversion pipes 230 are shown clearly (but only one detection box 300 is shown). In this embodiment, the pipeline includes 1 main pipe 210 and 2 water diversion pipes 230, which are connected using a tee pipe connection. The water sample in the main pipe 210 is split into 2 water diversion pipes 230 on average after passing through the three-way pipe connector, and is drained to the corresponding detection box 300. In a further embodiment, to measure the water flow on the shunt tubes and ensure that the water flow on both shunt tubes is consistent, a flow meter 240 is mounted on both shunt tube 230 tubes.

In the process of detecting the quality of surface water, dissolved oxygen is easily affected by an operation method, the water outlet end of a pipeline extends to the bottom of the detection box 300, specifically, in the embodiment, the water outlet end of the water diversion pipe 230 extends to the bottom of the detection box 300, the water outlet of the water diversion pipe is prevented from being too high, water samples are impacted with the bottom of the detection box or water in the detection box, oxygen in air is absorbed, and a large error occurs in the detection result of the content of the dissolved oxygen in the surface water.
