A large quantity of experimental waste liquid can be produced in the chemistry laboratory. If the liquid waste is handled improperly, it not only will pollute the environment, but also is harmful to our health. Taking the analytical chemistry laboratory teaching as an example, this paper analyzes the current situation of liquid waste management, discusses solutions of management and treatment, and puts forward suggestions to effectively reduce the production of liquid waste in laboratories, which provided reference materials for the chemical laboratory with similar problems.

Key words: Analytical chemistry laboratory, Experimental liquid waste, Classificatory treatment
