Description

Technical Field

[0001] The utility model relates to the technical field of water quality detection, in particular to a constant temperature aeration device for water quality detection. Background Art

[0002] Wastewater treatment is the process of purifying wastewater to meet the required water quality for discharge into a water body or reuse. Wastewater treatment is widely used in various fields, including construction, agriculture, transportation, energy, petrochemicals, environmental protection, urban landscapes, healthcare, and catering, and is increasingly becoming part of everyday life. Numerous methods exist for treating wastewater, which can generally be categorized as physical, chemical, and biological.

[0003] When testing BOD5 in sewage, it is necessary to use an aeration device to pre-treat the water sample and maintain a constant temperature (20℃±1℃). However, the existing aeration device has certain defects when used, such as:

[0004] The existing aeration device does not have a constant temperature function when in use. However, temperature also has a huge impact on microorganisms. The high temperature in summer causes the water sample temperature to be too high; the low temperature in winter causes the water sample temperature to be too low, which is not conducive to its promotion and use.

[0005] Therefore, how to provide a constant temperature aeration device for water quality detection has become a technical problem to be solved by those skilled in the art. Utility Model Content

[0006] The technical problem to be solved by the utility model is how to provide a constant temperature aeration device for water quality detection.

The design of the constant temperature mechanism makes the inside of the box reach a constant temperature state. According to actual needs, the heating water bath component and the cooling component are used to perform corresponding heating and cooling processes to ensure the aeration effect of the water quality sample, thereby ensuring the test results of the water quality sample.
