1、 Laboratory waste gas treatment
Under normal circumstances, the waste gas generated in the laboratory mainly includes volatile substances from reagents and samples, intermediate products from the experimental process, as well as leaked and emptied standard gas, carrier gas, etc. There are usually several treatment methods such as combustion, absorption, condensation, and activated carbon adsorption.
In planning and design, different numbers of fume hoods or fume hoods can be designed and installed according to the size of the laboratory. A small amount of harmless gases can be discharged outdoors through pipelines and diluted with air. A large amount of toxic gases must be fully burned or absorbed with oxygen before being discharged. At the same time, it is also important to consider the laboratory exhaust system, as many experiments require the exhaust function to be turned on.
2、 Laboratory wastewater treatment
There are three main sources of laboratory wastewater, namely: wastewater collected from outside, wastewater generated during the experimental process, and wastewater generated during the washing process, mainly organic wastewater and inorganic wastewater. Inorganic wastewater includes acids, alkalis, metals, and highly toxic substances such as cyanide. Organic wastewater includes waste liquid containing pollutants such as carbohydrates, phenols, alcohols, polycyclic aromatic hydrocarbons, and aromatic hydrocarbons.
Laboratory wastewater needs to be treated to meet standards before it can be discharged. Therefore, it is necessary to install laboratory wastewater treatment equipment to remove acids, alkalis, heavy metals, organic solvents, and kill pathogenic microorganisms, and complete the treatment according to regulations.
3、 Solid waste treatment
Solid waste, including empty drug bottles, drug residues, residual or ineffective chemical reagents, often requires pre-treatment. Hazardous waste liquids and solid waste that cannot be self treated should be classified, collected, labeled, and handed over to specialized hazardous waste treatment companies for treatment.
