Embodiment 1

[0029] The invention provides a microbial aerosol collection device for sewage treatment plants / processing stations, which is used to overcome the problem that traditional atmospheric sampling devices cannot complete the collection of microbial aerosols at different vertical heights. Refer to attached figure 1 , the microbial aerosol collection device mainly includes a sampling system 1, an extension system 2 connected to the sampling system 1 and an extension fixing system 3 for the adjustable installation of the sampling system 1.

[0030] Among them, refer to the attached figure 2 and 3 , the above-mentioned sampling system 1 includes a sampler, the sampler is specifically a portable medium-flow air sampler, which includes a sampling pump 11 and a sampling head 12; the extension system 2 includes a flexible hose 21 and a Green Head 22, the green head 22 is connected to the flexible hose 21 through its multi-ring convex plug, and the green head 22 at the lower end is fixe...

Embodiment 2

[0036] Select a municipal sewage treatment plant whose sewage treatment process is the SBR process, apply the device of the present invention to collect the microbial gas at the gas-liquid interface of the aeration tank (-1.5m away from the top of the aeration tank) and the vertical height of 4m at the top of the aeration tank Sol.

[0037] The gas-liquid interface and microbial aerosol collection device at different vertical heights mainly includes a sampling system 1, an extension system 2 connected to the sampling system 1, and an extension fixing system 3 for the adjustable installation of the sampling system 1.

[0038] Among them, the sampler of sampling system 1 adopts TH-150C intelligent medium-flow total suspended particle sampler from Wuhan Tianhong Instrument Co., Ltd., equipped with a TSP particulate matter cutter with a flow rate of 100L / min, which consists of a sampling pump 11 and a sampling head 12 .

[0039] The above-mentioned extension system 2 is composed ...

Abstract

The invention discloses a sewage treatment plant or treatment station microbial aerosol collecting device.The collecting device is mainly composed of a sampling system, an extending system and an extending fixing system.The extending system is composed of a set of corrugated connectors and a flexible hose; the extending fixing system is mainly composed of a main body rod with adjustable height, a pulley support, locating supports, a sampling head hanging basket and the like.The sewage treatment plant or treatment station microbial aerosol collecting device is simple and reasonable in design and easy and rapid to spice and install; limitation of a traditional collecting device is broken through, and meanwhile the device can complete sampling of microbial aerosols on a gas-liquid interface and at different vertical heights of a sewage treatment plant or treatment station rapidly, easily and conveniently; the device has important practical value for researching the escaping characteristic and diffusion rule of microbial aerosols in different spaces.

Description

technical field [0001] The invention relates to the field of atmospheric environment monitoring, in particular to a microbial aerosol collection device for a sewage treatment plant / processing station. Background technique [0002] Microbial aerosols in sewage treatment plants / processing stations refer to aerosol particles containing a large number of active components such as bacteria, fungi, and viruses that are mainly released into the atmosphere during the sewage treatment process. Existing studies have shown that high concentrations of microbial aerosols can escape during the process of aeration, mechanical stirring, etc. in urban sewage treatment plants / treatment station aeration tanks, coarse screens, fine screens, etc. ProcessBiochemistry, 2011(46), 910-915"), and these microbial aerosol particles contain a certain amount of potential pathogenic microorganisms, which have great potential harm to the health of sewage treatment plant / treatment station staff, nearby resi...
