After the completion of the experiment, the waste and waste liquid should be classified and collected, sent to the transfer station for temporary storage, and then handed over to a qualified unit for disposal.
Experimental waste is a general term for gaseous, solid, semi-solid and liquid substances that have lost their use value and are generated in the laboratory during teaching, research and other activities in the laboratory. After the completion of the experiment, waste and waste liquids should be classified and collected, sent to the transfer station for temporary storage, and then handed over to a qualified unit to deal with.
Three laboratory waste: exhaust, waste water, solid waste. It can also be called "raw materials in the wrong place". Recycling, but also to improve environmental health. Try not to use or minimize the use of chemical reagents containing heavy metals for experiments.
The implementation of scientific, reasonable and effective classification and management of experimental waste is directly related to the collection and treatment of waste can be carried out smoothly, but also to realize the intrinsic requirements of the safe management of experimental waste.
Precautions for the treatment of waste liquids
1, each laboratory should be equipped with containers for storing waste residues and waste liquids, and the waste residues and waste liquids produced by the experiments that are polluting to the environment should be categorized and poured into the designated containers for storage.
2, acidic, alkaline waste liquids according to their chemical properties, respectively, for neutralization and post-treatment. So that the PH reaches between 6 to 9 after discharge.
3, organic waste liquid, centralized for recycling, conversion, combustion and other treatments.
