Description

Technical Field

[0001] The invention relates to the technical field of water pollution collection, in particular to a water sample collection device for tracing the source of water pollution. Background Art

[0002] Water pollution is the deterioration or loss of water's usefulness caused by harmful chemicals, which pollutes the environment. Acids, alkalis, oxidants, compounds like copper, cadmium, mercury, and arsenic, and organic toxins like benzene, ethylene dichloride, and ethylene glycol in sewage can poison aquatic life, affecting drinking water sources and scenic landscapes. Microbial decomposition of organic matter in sewage consumes oxygen, impacting aquatic life. Once dissolved oxygen is depleted, the organic matter undergoes anaerobic decomposition, producing unpleasant gases like hydrogen sulfide and mercaptans, further deteriorating water quality.

[0003] When collecting and processing water samples for current water pollution, a sampling operation is performed by fixing a rope body and a tank body, and then putting the tank body into the water body. This makes it impossible to sample a specified water layer as needed. At the same time, the single collection structure means that only a single water layer can be sampled at a time, which affects the efficiency of water sampling. At the same time, sampling is more laborious and causes fatigue under human support, which affects the subsequent detection efficiency. Summary of the Invention
