How to detect the indoor environment in Langfang?

The basis of indoor environment detection consists of the following parts: 1, indoor air quality standard; 2. Public indoor environmental sanitation standards; 3. Limits of harmful substances in interior decoration materials; 4, civil construction engineering indoor environmental pollution control specification. Each standard has its own national standard.

Indoor environment detection method:

Indoor environmental detection is through indoor fixed-point sampling, and then take the data to the laboratory for further analysis and processing. Laboratory analysis methods include: spectrophotometry (formaldehyde, ammonia), gas chromatography (benzene, toluene, xylene), radon continuous monitor (radon) and stone radioactivity monitor (radioactivity).

Indoor environment management methods:

Pollution control mainly refers to the chemical pollution of formaldehyde, benzene and benzene series, ammonia and the control of pollution sources. According to the current technology, it is still difficult to control the radioactive source that releases radon gas, and it can only be controlled and used, and in serious cases, it can only be dismantled. Treatment methods include: photocatalyst treatment (formaldehyde, benzene, TVOC), ozone introduction treatment (benzene), negative ion treatment (formaldehyde, benzene, ammonia), carbon treatment (benzene), plant purification treatment, and nano-mineral crystal treatment.
