Description

Technical Field

[0001] The utility model relates to the technical field of water quality sampling, in particular to a sampling device for wastewater treatment. Background Art

[0002] Wastewater refers to discarded water that contains pollutants exceeding the prescribed limit and causes harm to the environment. It is usually generated during production, life and other activities. Wastewater contains harmful chemicals, heavy metals, microorganisms, suspended solids, etc. If it is not effectively treated and managed, it will pollute the soil, water bodies, and atmosphere and cause ecological damage, posing risks to human health. When testing wastewater treatment, a sampling device is needed to take samples, analyze them, and then collect and treat them.

[0003] The existing sampling device does not have the function of separating impurities. When testing the wastewater samples, since there are a lot of impurities mixed in the wastewater, it is not conducive to the detection work. At this time, it is necessary to separate the wastewater from the impurities before the detection work is carried out. The existing sampling device is inconvenient to clean, and the residual impurities in the device cannot be cleaned in time, which will cause the device to be blocked, affecting the subsequent work.
