Water-soluble odoring substance in waste gas, such as：Ammonia NH3 and hydrogen sulfide h2s and solid granule, and adjust the physical chemistry of air
Property, such as：Temperature and pH value.The humidity of air is improved, is that follow-up biofiltration creates conditions, after spray washing, air
Relative humidity reaches more than 95%, it is ensured that the water satisfied microorganism in filtering layer needs；Sprayed in pre- wash pool equipped with horizontal circulation
Humidification system, the horizontal circulation shower humidification system includes water circulating pump, shower nozzle, the circulating line being installed in pre- wash pool, should
The water that shower nozzle is sprayed nebulizes, and can cover whole pre- wash pool, in the absence of dead angle.Washing filler is provided with pre- wash pool, is washed
Filler is located at below shower nozzle, wherein, the washing filler uses PP materials.
S2, biofiltration：Air enters from the bottom of biological filter, and by first of setting in the middle part of biological filter
Air distribution plate is equably moved upwards, is fully contacted with the first air distribution plate and with the biologic packing material of certain humidity, smell
Material is first absorbed by biologic packing material, is then degraded by the microbiological oxidation in biologic packing material, to eliminate smell, completes removing for waste gas
Smelly process.Together with the pre- wash pool is built jointly with biological filter.
S3, UV photodissociation：Using UV photodissociation device to discharging the further deodorizing process of air from biological filter, and by rearmounted
Blower fan discharge is drawn, to be discharged into the external world.Foul gas behind biological filter substantially can qualified discharge, but due to micro-
Biological growth is influenceed that fluctuation, especially winter occurs by season, and the growth of microorganism is suppressed when temperature is relatively low, because
This, in end, increase UV photodissociation device can ensure processing system stably reaching standard, belong to end and ensure technique, this group technology can
To ensure that what the foul gas of the project can be steady in a long-term reaches discharge standard.
Feed manufacturing peculiar odor treatment technique of the present invention carries out Water spray using pre- wash pool 1 to waste gas, then using biofiltration
Pond 3 carries out microbiological oxidation degraded to waste gas, then carries out UV Photolytic deodorizations using UV photodissociation device 4, and three kinds of structures are passed through with this
And combinations thereof technique feed manufacturing waste gas is handled, and can effectively remove the waste gas produced during feed manufacturing and mainly have
Reach that national associated exhaust administers discharge standard after the foul gas such as ammonia, hydrogen sulfide, methyl mercaptan, processing, and will not produce secondary
Pollutant, the order present invention has the extremely strong market competitiveness.In addition, total investment of engineering of the present invention, operating cost are relatively low, give birth to relatively
Thing deodorization, plant liquid spraying processing waste gas technique, construction investment save about 20%, and operating cost saves more than 50%.
Certainly, the foregoing is only the specific embodiment of the present invention, not limit the scope of the present invention, it is all according to
The equivalent change or modification that construction, feature and principle described in scope of the present invention patent are done, all should be included in Shen of the present invention
Please be in the scope of the claims.
