1. Current status of laboratory pollution
With the rapid development of social economy, various types of laboratories continue to develop and expand, and as a place for the use and reaction of a large number of various chemicals, the laboratory also produces pollutants in the process of experiments and reactions, including some highly toxic and possibly carcinogenic exhaust fumes, liquids and solid waste. These pollutants are various in variety, complex in composition, small in total pollution, high in concentration, and difficult to treat and dispose of. However, if these pollutants are not treated and disposed of, they are directly discharged into the environment, accumulatively polluting and damaging the environment, and endangering the health of human beings. Therefore, the impact of laboratory waste on the environment cannot be ignored, and corresponding measures should be taken for disposal to ensure environmental safety.
2. Countermeasures for Prevention and Control of Laboratory Waste Pollution
2.1 The prevention and control of laboratory waste pollution, such as general chemical waste liquid requires the treatment of chemical waste liquid, which has a positive effect on reducing laboratory waste pollution. In the process of laboratory waste pollution prevention and control, the chemical waste liquid contains inorganic waste liquid, organic waste liquid, inorganic matter solution, etc., so in the process of treating this part of the waste liquid, professional chemical waste liquid can be used. During this process, open bottle containers cannot be used to store chemical solutions. In the process of laboratory waste pollution prevention and control, it can be combined with the type of waste liquid, and a clear label needs to be pasted on the barrel container to avoid the leakage of chemical waste liquid.
2.2 The highly toxic chemical waste liquid produced by the laboratory shall be properly kept in accordance with the management regulations of highly toxic reagents. Highly toxic waste liquid should be temporarily stored in a separate container. It is not allowed to store several highly toxic waste liquids in one container. For transshipment, fill out the "Registration Form for Highly Toxic Chemical Waste Liquid" and contact the qualified unit in time. Waiting for receipt and transportation, implement harmless treatment and disposal. For the disposal of highly toxic chemical waste liquid, it is necessary to reprocess the chemical waste liquid according to the characteristics of the highly toxic chemical waste liquid to reduce the toxicity of the chemical waste liquid. The comprehensive treatment of highly toxic chemical waste liquid, clarify the treatment process of highly toxic chemical waste liquid, and establish an effective management mechanism to improve the comprehensive treatment level of highly toxic chemical waste liquid. In the treatment of highly toxic chemical waste liquid, it can be combined with the development needs of the laboratory to abolish the highly toxic experiment, complete the basic operation training with the less toxic experiment, and use the micro experiment to replace the constant experiment.
2.3 Waste chemical reagents Waste chemical reagents (solid or liquid) should be stored in the original bottle, keep the original label, and indicate that it is a waste reagent, and properly manage it according to chemical reagents.
