Description

TECHNICAL FIELD

[0001] The utility model relates to waste liquid treatment technical field, concretely is a kind of laboratory calcium carbonate-containing waste liquid treatment device. BACKGROUND

[0002] In scientific research, education and industrial production and many other fields, the calcium carbonate-containing waste liquid generated in laboratory is a common waste, and if such waste liquid is not properly treated, it may not only pollute the environment, but also pose a threat to laboratory equipment and users' safety. Traditional calcium carbonate-containing waste liquid treatment methods mostly rely on precipitation method, that is, adding an appropriate amount of precipitant to the waste liquid to precipitate calcium carbonate in the form of precipitate.

[0003] However, in actual operation, impurities in the waste liquid may affect the precipitation effect, leading to incomplete precipitation of calcium carbonate or mixing with other substances, thereby increasing the difficulty and cost of subsequent treatment. In addition, manual stirring, precipitation, separation and other steps are usually required during the treatment process, which is tedious and inefficient. Therefore, we provide a laboratory calcium carbonate-containing waste liquid treatment device for use. UTILITY MODEL CONTENT
