Technical field
The present invention relates to a kind of deodoration systems of garbage transfer station, belong to field of environment protection equipment.
Background technology
Garbage transfer station be municipal refuse collect after to before being transported to refuse landfill, first carry out concentrate pretreatment ground
Side promotes and uses, not only beautified environment, but also prevented secondary pollution, reduced the growth of mosquitos and flies, improved vehicle-mounted effect
Rate alleviates labor intensity, substantially reduces operating cost.As people's living standard is continuously improved, to environmental condition
It is required that also increasingly improving, the refuse depot of traditional sense has been unable to meet people and the new concepts such as efficient, environmentally friendly, low energy is wanted
It asks, therefore compressed garbage station comes into being.In compacting refuse transfer station, after rubbish is concentrated compression, in certain temperature
Under degree and pressure, contained compound can react in rubbish, give out a variety of volatile organic matters, according to detection in spring
47 kinds can be measured, summer can measure 64 kinds of volatile matters, and these volatile matters all have strong peculiar smell, seriously affect control matter
Amount.
In the prior art, multi-purpose microbiological treatment sends the volatile materials of peculiar smell that removal is also easy to produce, and this kind of method is not
Only workload is very big during microorganism is chosen seeds, and also relatively slow when handling volatile materials, and working efficiency is relatively low.
