Problems solved by technology

[0004] This passive manual monitoring method cannot manage, prevent, and control the emission of malodorous gases in real time; it cannot detect and solve sneaky emissions, leaked emissions, and sudden environmental problems in time, which is not conducive to supervision
Moreover, the stench is very harmful to the body and spirit of the odor smeller, and its accuracy is often questioned
[0005] Therefore, the cu

Abstract

The invention discloses a dual-mode air peculiar smell monitoring and early warning system based on characteristic pollutants and an electron nose. The air monitoring and early warning device comprises a polluting substance concentration monitoring module and a peculiar smell monitoring module, wherein the polluting substance concentration monitoring module is arranged for monitoring the polluting substance concentration in the air; and the peculiar smell monitoring module is used for monitoring the peculiar smell in the air. According to the air monitoring and early warning device of the invention, the main polluting substance concentration can be measured continuously, the air peculiar smell sensing degree can be monitored quantitatively, the air peculiar smell monitoring management technical defects in the prior art are overcome, real-time, online and remote air sampling, monitoring and early warning can be carried out on the air environment, and the system of the invention can be applied to real-time remote monitoring, emergent early warning and coordinated control of an odor pollution source region, a frontier district and a surrounding sensitizing range.

Description

technical field [0001] The invention relates to the field of environmental monitoring, in particular to a dual-mode air odor monitoring and early warning system based on characteristic pollutants and an electronic nose. Background technique [0002] Air odors such as stench, pungent fragrance and other exhaust gases are more than other air pollution, which is a kind of environmental pollution mainly caused by the psychological impact on people. The health of the working people near the source of the air odor and the people in the surrounding sensitive areas will be directly harmful. [0003] At present, there are more than 4,000 kinds of odorous substances known, and the common ones are hydrogen sulfide, sulfur dioxide, mercaptans, sulfides, ammonia, volatile organic compounds (VOCs), indoles, etc., which emit odors similar to those of rotten eggs. , rotten onions, manure and other unpleasant or irritating odors, malodorous gases pollute the ambient air and have an impact o...
