detailed description

Below in conjunction with accompanying drawing and embodiment, the specific embodiment of the utility model is described in further detail. The following examples are used to illustrate the utility model, but not to limit the scope of the utility model.

Embodiment: A device that can comprehensively treat inorganic waste liquid in a chemical laboratory, including an acid pool 1 for storing acid waste liquid, an alkaline pool 2 for storing alkaline waste liquid, and a reaction pool 3, the acid pool and alkaline pool They are all arranged above the reaction pool and communicate with the reaction pool through the first and second pipelines 4 and 5 respectively, and the reaction pool is also connected with a third pipeline 6 for the flow of laboratory waste liquid that needs to be treated. A sedimentation tray 7 is freely placed at the inner lower end of the reaction pool, and a filter device 8 is communicated with the bottom of the reaction pool.

The acidic and alkaline waste liquids in the laboratory can be stored separately through the acidic pool and the alkaline pool. According to the nature of the chemical experiment waste liquid to be treated, the acidic and alkaline waste liquids can be reasonably selected and processed through the reaction pool to utilize The waste liquid is used to treat the waste liquid, so that the waste liquid can be effectively used.
