Abstract

The utility model relates to an aerobe filtering bed deodorizing device, which is applied to a sewage treatment system. The aerobe filtering bed deodorizing device is formed by that an odour collecting device, an aerobic reaction tank, a chimney, etc. are orderly connected; the bottom of the aerobic reaction tank is provided with a micropore aeration disk; the aerobe filtering bed deodorizing device utilizes that microorganisms in the aerobic reaction tank bring about a biochemical reaction to absorb, sorb and decompose odour pollutants to complete a deodorizing process. In order to ensure deodorizing effect, aeration deodorizing can be circularly carried out.

Description

System Deodorant Device

Technical field the utility model relates to a kind of System Deodorant Device that is applicable to sewage treatment area, and stink in the sewage is removed as the deodorizing bacteria bed in the aerobic reaction pond.

Background technology sewage is the movable various polluted water that produce such as production, life, amusement, its definition has been contained sanitary sewage, rainwater and has been produced the industrial sewage that produces, and variously gives out diversified, odour nuisance by different ratios blended sewage.Especially fecal sewage, the smell that human desires is vomitted in more producing is to be difficult to the problem of evading in the water treatment., people are listed in the table below several main, odour nuisances and compound.These compounds are present in the sewage, or produce in sewage treatment process.

Several main odour nuisances in the fecal sewage

Compound	Typical case's molecular formula	Odor characteristics
			Amine	CH 3NH 2，(CH 3) 3N	Fishy smell
Ammonia	NH 3	The ammonia flavor
			Diamines	NH 2(CH 2) 4NH 2，NH 2(CH 2) 5NH 2	The slough flavor
Hydrogen sulfide	H 2S	Rotten-egg odour
			Mercaptan	CH 3SH，CH 3(CH 2)SH	The skunk flavor
Organic sulfide	(CH 3)S，CH 3SSCH 3	Mashed Chinese cabbage flavor
			Skatole	C 8H 5NHCH 3	The ight soil flavor

Existing sewage treatment process generally is to set up the deodoration system of a cover at foul smell outside water treatment system separately, in deodorizing tower, install gac additional, rely on charcoal absorption effect deodorizing, or in deodorizing tower, install bacteria bed additional, rely on the biochemical reaction deodorizing of biological bacteria.These odor removals exist investment bigger, and floor space is big, and the deodorizing raw material need regularly replace, and running cost is than problems such as height.

Summary of the invention

In order to solve the problem that existing Sewage treatment systems odor removal partly exists, existing odor removal and technology are reformed, the device that the utility model provides a kind of novel bacteria bed effect of making good use of oxygen reactor to dispose of sewage foul smell, this device can directly pass through the foul smell that produces in the sewage or exist the biochemical action of aerobe filter bed in the aerobic reaction pond, remove the stink in the gas, reach respective standard to guarantee the gaseous emission in the sewage disposal.

The utility model solves the scheme that its technical problem takes: collect through multiple spot from the foul smell that each foul smell leak point gives out, by the concentrated aerobic reaction pond of sending into of blower fan, throw in corresponding microorganism species in the aerobic reaction pond, form the bacteria bed of aerobic reactor, foul smell via wherein microorganism absorption, absorption, Decomposition after, removed the smelly compound that causes in the foul smell, discharged by exhaust port after the gas after being filtered by the aerobic reaction pond enters chimney.Can utilize the operation of cyclic aeration to eliminate the interior foul smell of native system in addition.

The beneficial effects of the utility model are: need not to design separately, install odor removal in Sewage treatment systems, avoid overlapping investment, the minimizing project is taken up an area of, and reduces working cost, guarantees foul smell processing up to standard, emission standards simultaneously.

Description of drawings

Below in conjunction with accompanying drawing and example the utility model is further specified

Fig. 1 is the utility model structural representation.Among the figure: the 1st, the foul smell inlet; The 2nd, blower fan; The 3rd, the aerobic reaction pond; The 4th, the micro-pore aeration dish; The 5th, chimney; The 6th, exhaust port; The 7th, the foul smell transport pipe.

Embodiment

Foul smell from Sewage treatment systems enters this device by foul smell transport pipe " 7 " by " 1 " foul smell inlet, and is transported to " 3 " aerobic reaction pond by " 2 " blower fan; In " 3 " aerobic reaction pond, by " 4 " micro-pore aeration dish aeration, foul smell is fully contacted with wherein microorganism, biochemical reaction takes place, the odor pollution thing is absorbed, adsorbs, decomposes the stink in the back elimination tail gas, the tail gas that produces is transported to " 5 " chimney, discharges in the high-altitude through " 6 " exhaust port.

Claims (3)

1) a kind of System Deodorant Device is characterized in that: foul smell transport pipe and aerobic reaction pond, chimney device are linked together.

2) the system as claimed in claim 1 odor removal is characterized in that: install the micro-pore aeration dish additional in the aerobic reaction pond, and be connected with the foul smell transport pipe.

3) the system as claimed in claim 1 odor removal is characterized in that: install blower fan additional on the foul smell transport pipe.
