The high-performance bio the deodorizing device below embodiment of the present invention being provided is described in detail.
As shown in Figure 1, a kind of high-performance bio deodorizing device, it specifically can comprise the following steps: trickling filter 1, air blast 2, bacterium flow container 3 and the first water pump 41; The inside of trickling filter 1 is provided with cylindricality cavity; This cylindricality cavity is provided with demister 9, the first spray thrower 71, the first porous aggregate bed 61, the second spray thrower 72, the second porous aggregate bed 62 and gaseous diffuser 5 from top to bottom successively; The bottom of trickling filter 1 is provided with air inlet, and gaseous diffuser 5 is communicated with the air blast 2 of trickling filter 1 outside by this air inlet; The bottom of trickling filter 1 is communicated with the inlet of bacterium flow container 3 and the inlet of the first water pump 41 respectively; The liquid outlet of bacterium flow container 3 is communicated with the inlet of the first water pump 41; The liquid outlet of the first water pump 41 is communicated with the inlet of the first spray thrower 71 and the inlet of the second spray thrower 72 respectively;
The foul smell of odor source enters gaseous diffuser 5 under the effect of air blast 2, and by gaseous diffuser 5, is diffused into the inside of trickling filter 1; Foul smell spreads from bottom to top in the inside of trickling filter 1, and is constantly cleaned, until discharge from being located at the gas outlet at trickling filter 1 top;
In bacterium flow container 3, be provided with deodorizing bacterium liquid; This deodorizing bacterium liquid comprises following each raw material by weight ratio: 800~1300 parts of the supernatants of the mixture of activated sludge and secondary matured waste, and the nitrobacteria after acclimation: 35~65 parts, 40~60 parts, the sulfuration bacterium after acclimation.
Particularly, the specific implementation of each parts of this high-performance bio deodorizing device can comprise:
(1) between the bottom of trickling filter 1 and the inlet of the first water pump 41, can be provided with the first valve 81; Between the inlet of the bottom of trickling filter 1 and bacterium flow container 3, can be provided with the second valve 82.
When the first valve 81 is closed, when the second valve 82 is opened, the deodorizing bacterium liquid in bacterium flow container 3 enters the first spray thrower 71 and the second spray thrower 72 under the effect of the first water pump 41, and by the first spray thrower 71 and the second spray thrower 72 sprays, arrives the inside of trickling filter 1; Deodorizing bacterium liquid can move downward gradually in the inside of trickling filter 1, and constantly foul smell is purified, until be collected at the bottom of trickling filter 1; The deodorizing bacterium liquid that is collected at trickling filter 1 bottom can turn back to bacterium flow container 3 by the second valve 82, thereby deodorizing bacterium liquid is circulated between trickling filter 1 and bacterium flow container 3.
When the first valve 81, open, when the second valve 82 is closed, the first water pump 41 obtains the deodorizing bacterium liquid that is collected at trickling filter 1 bottom by the first valve 81; Deodorizing bacterium liquid enters the first spray thrower 71 and the second spray thrower 72 under the effect of the first water pump 41, and by the first spray thrower 71 and the second spray thrower 72 sprays, arrives the inside of trickling filter 1; Deodorizing bacterium liquid can move downward gradually in the inside of trickling filter 1, and constantly foul smell is purified, until turn back to the bottom of trickling filter 1, thus make the self-loopa on trickling filter 1 of deodorizing bacterium liquid.
Generally, this high-performance bio deodorizing device adopts the method for operation of deodorizing bacterium liquid self-loopa on trickling filter 1, and the first valve 81 is opened, and the second valve 82 is closed; This method of operation can make deodorizing bacterium liquid have a circulation rate faster, has improved odor removal efficient and has processed load, has saved operating cost.When the odor concentration of gas outlet institute Exhaust Gas of being located at trickling filter 1 top is during lower than primary standard in emission standard for odor pollutants (GB GB14554-93) (when the deodorizing capability of high-performance bio deodorizing device declines), the method of operation that this high-performance bio deodorizing device adopts deodorizing bacterium liquid to circulate between trickling filter 1 and bacterium flow container 3, the first valve 81 is closed, and the second valve 82 is opened; This method of operation can add to the deodorizing bacterium liquid in bacterium flow container 3 in trickling filter 1, thereby has improved deodorizing capability.These two kinds of methods of operation are used as required, can save operating cost, can guarantee that again this high-performance bio deodorizing device has stronger deodorizing capability and odor removal efficient faster.
