Methods for handling the “three wastes” generated in laboratories
Thread Content
During laboratory operations, a large amount of analytical waste liquid is generated. Does any teacher know what procedures should be followed to handle such waste in accordance with the requirements set by environmental protection authorities?
Acidic and alkaline waste liquids should be neutralized to meet the wastewater discharge standards (pH value of 6.5–9.5). Organic waste liquids and heavy metal waste liquids are advised to be collected and treated as hazardous waste; waste solvent bottles are similar in this regard.
Everything must be recycled; it is not allowed to discharge or dispose of it carelessly and cause pollution. It would be best to have specialized agencies for handling this!
