Abstract
The invention provides a biological filtration and deodorization device which comprises a humidifier and a biological deodorization tower, wherein the biological deodorization tower comprises an air distribution system, an active biological filter bed and a top air exhaust from the bottom to the top. The invention further provides a biological filtration and deodorization method which comprises the following steps: stench collected by a draught fan is delivered in a humidification tower for pretreatment, flows into the air distribution system at the bottom of the biological deodorization tower, and slowly passes through the active biological filter bed from bottom to top for purification, and purified air leaves the surface of the filter bed in an air-flow diffusion mode, is discharged from the top of the biological deodorization tower, and enters the atmosphere.
Description
Technical field
The present invention relates to a kind of device and method that utilizes microorganism to carry out biological filter deodorizing, belong to field of Environment Protection.
Technical background
Various anaerobism discarded object component of refuse in biogas engineering are complicated, pretreatment stage can because of poor aeration and be subject to the effect of microorganism very easily corrupt, foul, produce with H
2s and NH
3be main, also have the foul gas of the compositions such as a small amount of methyl mercaptan, methylamine, methyl sulphur simultaneously.These gaseous volatilizations are larger, be easily diffused in atmosphere, and portion gas are poisonous, penetrating odor is large.Not only affect operating personnel's health, also can affect periphery resident's life, contaminated environment, especially even more serious in impact in summer.
Summary of the invention
The object of this invention is to provide a kind of device and method that utilizes microorganism to carry out biological filter deodorizing.
The device of a kind of biological filter deodorizing of the present invention, comprises humidifier and biological deodorizing tower, and described biological deodorizing tower is respectively air distribution system, active bio filter bed, top vent from lower to upper.
Further, in described active bio filter bed, filler is set.
Further, described filler is wood chip.
Further, described humidifier bottom arranges coil pipe, hot water control valve and temperature monitoring system.
Further, in described humidifier, be also provided with spray system.
The method of a kind of biological filter deodorizing of the present invention, that the foul smell of being collected by air-introduced machine is sent into and in humidification tower, carried out pretreatment, the gas obtaining enters the air distribution system of biological deodorizing tower bottom, slowly by active bio filter bed, purify from lower to upper, air after purification leaves filter bed surface in the mode of diffusion air-flow, and discharge from the top of biological deodorizing tower, enter in atmosphere.
Further, in described humidification tower, relative humidity is 90%-95%, and temperature is 10-40 ℃.
The beneficial effect that the present invention produces is, without specific conditions such as high temperature, high pressure, removal efficiency is high, and reaction speed is fast, does not produce secondary pollution, harmless, and investment is saved relatively, and operating cost is low.
The specific embodiment
The device of a kind of biological filter deodorizing of the present invention, mainly comprises humidifier and biological deodorizing tower two parts, and described biological deodorizing tower is respectively air distribution system, active bio filter bed, top vent from lower to upper.
The foul smell of being collected by air-introduced machine is the relative humidity to 90%-95% through humidifying device pretreatment, in humidifier, can also comprise temperature-adjusting device, be specially in humidifier bottom coil pipe and temperature monitoring system are set, by hot water control valve, adjust the temperature to 10-40 ℃; In described humidifier, spray system impact air-flow can also be set, particle is removed.
The gas of collecting after humidifier pretreatment is sent into the air distribution system that is positioned at biological deodorizing tower bottom, again slowly by active bio filter bed, in described active bio filter bed, filler is set, pollutant in gas is from gas phase main diffusion to the outer field moisture film of filler and adsorbed by filler, finally be degraded to carbon dioxide, water etc., air after purification leaves filter bed surface in the mode of diffusion air-flow, and discharges from the top of biological deodorizing tower, enters in atmosphere.
Packing layer in described biological deodorizing tower is the filtrate that has adsorptivity and contain a large amount of organic matters, as multiple different types of wood chip, for different types of growth of microorganism, optimizes the treatment effeciency of deodoration system.Alkane derivative can be removed effectively as propane, iso-butane by its abundant microbiologic population, to the biological easily better processing effect of degradation material such as ester and ethanol.
Causing the degradation process of smelly pollutant in biological deodorizing tower can represent with following reaction equation:
