Industrial waste gas pollutant bioremediation mainly contains biological washing bed, Biotrickling filter, biofiltration bed etc. at present; The problem that in the bioremediation process, exists has: the mass transfer process that is changed over to liquid phase by gas phase; Because of receiving the influence of factors such as bio-film colonization, air quantity, humidity, the time of staying, biological bacteria, pressure; Be prone to take place filtrate and problems such as the sex change of hanging film, microbial activity reduction, cause the short-circuit flow of air film contact, thereby the purification efficiency of pollutant waste gas is reduced.In addition; Water-soluble and biological degradability to gas pollutant requires also higher; The startup of bioreactor, microbial acclimation, processing procedure longer duration, and specific area of filler, porosity, flowing resistance etc. are the subject matter of present biological purification tower.Because biological purification tower exists effect not good enoughly to cause bacterial activity reduction, overstand, easy blocking, influences mass transfer effect, the equipment design is not ideal enough, and then directly influences operating cost of whole biological cleaning Tower System or the like.For this reason, many manufacturers and knowledgeable people develop and study, but so far solution are not preferably arranged as yet.

Summary of the invention

For overcome that existing biological purification tower exists above-mentioned defective, the purpose of the utility model provide a kind of simple and reasonable, flowing resistance is low, treatment effect is excellent, microorganism gives birth to and brings up, treating capacity big, the horizontal biological purification tower of operation high-efficiency and economic.

The utility model solves the problems of the technologies described above the technical scheme that is adopted; It comprises tower body, is fixed on the column foot on the tower body; Described tower body constitutes horizontal type structure by outside steelframe and the anticorrosion liner plate in inside that is fixed on the steelframe, and the horizontal inner cavity chamber of tower body is separated into one-level airflow uniform distribution expansion chamber, one-level process chamber, secondary air flow by screen successively and is uniformly distributed with expansion chamber, two stage treatment chamber and three grades of airflow uniform distribution expansion chambers; Fill one-level filler, the indoor filling secondary of said two stage treatment filler in the said one-level process chamber; Said one-level airflow uniform distribution expansion chamber is provided with air inlet; The top of said three grades of airflow uniform distribution expansion chambers is provided with demister, and the top is provided with air outlet.

The top correspondence that said one-level airflow uniform distribution expansion chamber and secondary air flow are uniformly distributed with expansion chamber is provided with spray head, and the bottom of said tower body is provided with liquid storage tank.

Be provided with reinforcing prop in the described tower body, screen is fixed on the reinforcing prop.

After adopting said structure; Following advantage and effect are compared with prior art arranged: owing to adopted a plurality of airflow uniform distribution expansion chambers and process chamber series connection structure; Exhaust emission is divided equally at airflow uniform distribution sedimentation indoor air flow, and big particles settling, exhaust emission are accomplished the mass transfer process that is changed over to liquid phase by gas phase in process chamber; Absorption at microbe stuffing absorbs under the interaction; Make the pellicle of exhaust emission from the Liquid Phase Diffusion to the microorganism, exhaust emission is decomposed by microorganism and utilizes, and the pellicle pollutant is changed in the cells of microorganisms; Get into microbial cell internal contamination thing as the energy of microbial life activity or support part and be decomposed and utilize, thereby make exhaust emission be able to remove.Accelerated the completion speed that gas phase changes the mass transfer process of liquid phase over to greatly; Flowing resistance is reduced, improved activation of microorganism, increased the biomass in the filler; Shortening is the time of staying in process chamber, thereby has improved the clean-up effect of exhaust emission greatly.
