The three modules are modularized, and when the three modules are installed, the complete trickling filtration tower can be formed by stacking and assembling, the assembly can be completed on site after the modularization, the single module can be transported, the transportation is convenient, and the difficulty of manufacturing is reduced; the assembled trickling filtration tower can treat odor, the fan works to enable the odor to enter the circulating outer shell through the air inlet arranged on the circulating outer shell, then the odor passes through the carbon filler filled in the filler module 1 from bottom to top under the suction effect of the fan, is captured and degraded by microorganisms attached to the surface of the carbon filler and in circulating liquid, the odor is purified and discharged, and finally the odor enters the air outlet pipe 5 through the gas collecting hood 4 and is discharged; the carbon material in the embodiment selects bamboo charcoal, and the filler is an important component of the biological deodorization tower, is not only a carrier for attaching and growing a biological membrane, but also determines the formation and flow state of a gas-liquid-solid three-phase interface, thereby influencing the deodorization efficiency and the treatment cost. Bark, shells, volcanic rocks and the like are mostly adopted as biological fillers of deodorization equipment in the market, and the fillers have the defects of small specific surface area, poor moisture retention, low compressive strength, easy decay or weathering, easy short circuit and the like, so that the biological deodorization efficiency is not high. When the device is operated for a long time, the phenomenon of reactor blockage caused by excessive growth of microorganisms occurs, meanwhile, the practical application of the biological deodorization technology is greatly influenced by the problems of low recovery speed after the device is shut down accidentally, short service life of the filler, environmental pollution caused by odor when the filler is replaced and the like, the bamboo wood has a special pore structure, the bamboo charcoal formed by high-temperature heat treatment inherits the original characteristic of a large pore structure, and the porosity of the common bamboo charcoal is 51%; 53.54 percent of the volume of the bamboo charcoal distributed in the pore diameter of 0.02-5 mu m, the bamboo charcoal is favorable for the growth of microorganisms, has the advantages of large specific surface area, strong adsorption capacity, high strength, low pressure drop in long-term operation and the like, is very suitable to be used as a filler in a biological deodorization process, screens the manufacturing and source of the bamboo charcoal in the market according to the good physicochemical property of the bamboo charcoal, and further modifies the bamboo charcoal. Finally, after modification, the carbon filler can be obtained by repeatedly washing with hydrochloric acid and deionized water. Through modes of carbonization, optimization of post-treatment modification conditions and the like, the surface of the filler is provided with positive charges, and attachment growth of microorganisms with negative charges is facilitated. The filler mainly comprises mesopores and macropores, is obviously different from coal-made active carbon, and can see obvious pores under a lower magnification, so that the special charcoal filler for biological deodorization, which is prepared by modifying and activating bamboo charcoal, overcomes the defects of low biomass, short service life and poor stability of the conventional filler; oxidative decomposition of hydrogen sulfide is due to the oxidation of autotrophic sulfur-oxidizing bacteria, which obtain energy from the oxidation of hydrogen sulfide and produce sulfuric acid. Because the microorganism produces sulfuric acid in the process of metabolism, the pH value of the circulating liquid can be rapidly reduced to 1-2 in the practical engineering. The carbon filler can resist acid corrosion and has long service life. The carbon filler has a porous structure, so that the carbon filler has good water retention capacity, the water consumption per unit volume is only 0.2 t/(m3 filler d), and the characteristic can reduce the intermittent spraying of the system for the whole system
The frequency of sprinkling is high, thereby greatly saving the water consumption. Meanwhile, when the deodorization device is shut down accidentally, the filler can be kept moist for a long time (10-15 days), and the activity of microorganisms is kept, so that when the device is recovered to operate, the deodorization effect can be rapidly recovered to the optimal state;
acidic substances are easily generated when the trickling filtration tower is used for treating malodorous substances such as hydrogen sulfide methyl mercaptan and the like, and the filler layer is easily acidified. Acidified fillers tend to cause packing compaction, and acidification changes the packing layer structure (porosity). In the actual operation process, the wind resistance of the biological packing layer at the unit height of the biological deodorization device (including the wind resistance of the over-wind of the packing, the resistance loss of the inlet and the outlet of the device and the wind resistance of the prewashing spraying section) has correlation with the flow rate of the empty bed, the void space ratio and the like, the high flow rate of the empty bed can increase the wind resistance of the packing at the unit height to further influence the air flow distribution and further influence the collection effect of the whole odor collection system and the treatment efficiency of the odor treatment device, the great reason for generating compaction is that the height of the carbon packing layer is too high, the carbon packing at the bottom can be compacted under the action of gravity, in order to solve the technical problem, the embodiment is provided with a plurality of floating support mechanisms 6 above the fixed support plate 8, the support grids 16 in the floating support mechanisms 6 and the fixed support plate 8 divide the space in the packing shell body 15 into a plurality of packing cavities in the vertical direction, and the relative positions of the fixed support plate 8 and the packing shell body 15 are unchanged, the upper part is filled with carbon filler, the fixed supporting plate 8 and the supporting grid 16 are both made of polyurethane, are porous and have good strength and corrosion resistance; the floating support mechanism 6 provided in this embodiment can support the filled carbon filler to a certain extent, the gravity for placing the carbon filler is all pressed on the fixed support plate 8, the carbon filler at the bottom is compacted, so that the compaction condition can be reduced, a plurality of support cylinders 17 are provided on a circle of the same plane in the filler outer shell 15, the support cylinders 17 can be fixed on the inner wall of the filler outer shell 15 by bolts or welding, as long as the position can be fixed, the support cylinders 17 need to bear the gravity of the carbon filler, the support cylinders 17 are of a cylindrical structure with an open upper end, cylindrical round holes are provided inside, support springs 19 are provided in the holes, the bottoms of the support springs 19 can be fixed at the bottoms of the round holes or not fixed, then the bottoms of the sliding support rods 18 are placed in the support cylinders 17 and pressed on the support springs 19, the sliding support rods 18 support the support grids 16, the first layer of carbon filler is filled on the fixed supporting plate 8, then the first floating supporting mechanism 6 above the fixed supporting plate 8 is installed, the bottom of the supporting grid 16 of the floating supporting mechanism 6 is contacted with the top of the first layer of carbon filler on the fixed supporting plate 8, then the supporting grid 16 is filled with the second layer of carbon filler, the second floating supporting mechanism 6 is installed on the second layer of carbon filler, the bottom of the supporting grid 16 is also placed on the second layer of carbon filler, so that the rest floating supporting mechanisms 6 are installed, thus the supporting grid 16 shares and supports the gravity of the carbon filler when each layer of carbon filler supports the carbon filler above, finally, part of the gravity is supported by the supporting cylinder 17, the supporting spring 19 arranged in the supporting cylinder 17 is compressed under the gravity bearing of the supporting grid 16, when the compaction condition is generated, the height of the carbon filler is changed, the height of the carbon filler below the supporting grid 16 is reduced, at this time, the supporting grid 16 is changed, part of supporting force of the carbon filler above the lower carbon filler is shared by the supporting cylinder 17, and at this time, the supporting spring 19 is further compressed, so that the bottom of the supporting grid 16 is always in contact fit with the top of each layer of carbon filler; can alleviate the condition of carbonaceous filler compaction through such design, still one benefit can increase the restriction of carbonaceous filler height, and traditional filler height upper limit is about two meters, can fill higher carbonaceous filler after the design like this, promotes the treatment effect of foul smell.
