Online collection and analysis system for biological aerosol released by anaerobic fermentation of household garbage and application of online collection and analysis system

Abstract

The invention discloses an online collection and analysis system for biological aerosol released by anaerobic fermentation of household garbage and application of the online collection and analysis system. The collection and analysis system comprises a detachable garbage fermentation reaction device, an aerosol collection device and an aerosol sampling device which are sequentially connected, the detachable garbage fermentation reaction device comprises a leachate collection tank, a circulating collector and a dosing tank, the circulating collector is connected with the leachate collection tank, and the leachate collection tank is connected with the dosing tank; the circulating collector is connected with the aerosol collecting device through a bolt flange structure; the aerosol sampling device comprises an aerosol sampling box and a sampler main machine, a sieve hole type impact disc is arranged in the aerosol sampling box, the aerosol sampling box is connected with the sampler main machine, the sampler main machine is connected with the circulating collector, and the leachate collection tank is embedded in the base. The system is good in sealing performance and convenient to sample, and can be used for fermentation of household garbage and collection, analysis and research of corresponding aerosol.

Description

technical field [0001] The invention belongs to the technical field of aerosol collection and analysis, and more specifically relates to an on-line collection and analysis system for anaerobic fermentation of domestic garbage to release bioaerosol and its application. Background technique [0002] Landfill is still the main domestic waste treatment method in my country. During the landfill process, organic waste undergoes mineralization and humification, and degradable organic components undergo continuous decomposition and transformation, which brings sensory impacts and effects on humans that cannot be ignored. Environmental pollution, during the fermentation process of garbage, solid and liquid substances, including bacteria, microorganisms and debris, are aerosolized and suspended in the air, which will cause the direct environment for human exposure. The rich gas production and microbial activities in the fermentation process have become a subject of many researches. focu...

Problems solved by technology

[0003] Drainage tanks and gas-collecting bags are often used in various waste fermentation reactors to collect gas or exhaust pipes are installed to discharge waste gas, but there are problems of being unable to store a large amount of gas and collect aerosols, and being able to store enough gas becomes the key to analyzing the composition of aerosols
