Analysis of Sampling and Pre-treatment Methods of Air Pollutants in Indoor Environment Detection
This article mainly analyzes the main sources of indoor air pollutants and the sampling and pre-treatment methods of air pollutants during indoor environment testing.First,the main sources of indoor air pollutants are introduced.Then,for gaseous pollutants,sampling methods such as direct sampling,passive sampling and powered sampling were analyzed.For particulate matter,sampling methods such as filter media and natural sedimentation were explored.Finally,in terms of pre-treatment of indoor air pollutants,methods such as active ventilation,plant adsorption,intelligent system environmental pollution control,and activated carbon adsorption can be adopted.It is expected that through the implementation of the above methods,harmful substances in the air can be effectively removed,indoor air quality can be improved,and the health of residents can be protected.
