condensing the dehydrated odor to dust-free odor with the temperature of about 35 ℃, washing with water again to remove dust, deacidifying, and deodorizing by biological bacteria, wherein the basic reaction formula is as follows: malodorous gas + O2 MicroorganismsCellular metabolites + CO2+H2And O. However, the malodorous gas has different components and different decomposition products, and different microorganisms have different decomposition and metabolism products. Therefore, the dust-free odor must be retained for 36 seconds or more to ensure that the sericin body secreted by the phage can adsorb odor molecules as much as possible. Meanwhile, when the PH of the deacidification solution recycled for a long time is between 4 and 6, the solution is recycled after neutralization and purification treatment by adding alkali.
In this process, the odor follows the reaction formula-malodor + O2 MicroorganismsCellular metabolites + CO2+H2O-reacting, adsorbing by phage mycelium secrete silk wool collagen, metabolizing by carbon through special enzyme of the phage mycelium, performing self-circulation metabolism on microbial flora and insect flora in the box, automatically controlling nutrient solution and self-circulation spraying to wash when the insect flora metabolite deposition standard exceeding detector gives an alarm after a period of time, and washing to obtain a mixed solution containing various insect flora metabolites, wherein the metabolites are recycled through flora self-reproduction restoration. The odor entering the biological bacteria phagocytosis filter bed processor is washed by weak base, dedusted and deacidified, the generated wastewater is precipitated by a sedimentation tank and reused, the washing liquid is automatically added when not enough, the sludge in the sedimentation tank enters a dryer for baking and dehydration, and then enters a carbonization system for treatment, so that no productive solid waste is generated completely.
In the specific implementation, the malodorous gas has different components and different decomposition products, and different microorganisms have different catabolic products. For nitrogen-free organic materials such as phenol, carboxylic acids, formaldehyde, etc., the final products are carbon dioxide and water; for sulfur-type malodorous components, the sulfur-type malodorous components are oxidized and decomposed into sulfate ions and sulfur under aerobic conditions; for nitrogen-containing malodorous substances such as amines, NH is released by ammoniation3，NH3Can be oxidized into nitrite ions by nitrosobacteria and then further oxidized into nitrate ions by nitrobacteria to finally generate H2O、CO2。
Energy metabolism mode:
the UV photolysis and plasma combined deodorization device 103 sends various missed peculiar smell molecular bodies into high-energy plasma deodorization equipment under the pushing of negative pressure air by using self-cleaning type circulating biological bacteria phage filter bed in discharged air without capturing the discharged air, and the high-energy plasma deodorization equipment is driven to deodorize every 1cm3The ozone generator can generate 1000 ten thousand positive ions and 800 ten thousand negative ions per second, a small amount of ozone molecules in the channel are scattered in the channel and collide with a large amount of positive ions and negative ions which are equally released in the channel to generate secondary activation, the ozone is excited and activated to generate more ionized oxygen in the air to form a large amount of positive ions, negative ions and active oxygen ion field environment in the space, so that the ozone generator can carry out oxidative decomposition on peculiar smell organic molecules passing through the space, and also has wall-breaking oxidability on protein molecule groups, so that various group or chain type peculiar smell pollutants in the air can be fully decomposed and oxidized into harmless and odorless CO2、H2O, NO molecules, thereby completely eliminating the peculiar smell molecule in the air.
TiO2Ozone and OH (hydroxyl radical) generated by the reaction carry out a synergistic decomposition oxidation reaction on malodorous gas (hydrogen sulfide, ammonia gas and mercaptan), and meanwhile, the molecular chain of the malodorous gas is structurally broken into whole chain under the action of ultraviolet rays, so that the malodorous gas is converted into a small molecular compound without odor or mineralized to generate water and CO2(ii) a Photolysis reaction mode:
organic waste gas → Wei wave + photolysis + O2→ O- + O (active oxygen) O + O2→CO2+H2O。
In this example, the odor molecule is various unimolecular bodies, microspores, single cells, and other odor molecule bodies that are not destroyed in the odor.
The system thoroughly abandons the traditional spraying method technology adopted for high-temperature waste gas, and the spraying method has the advantages of fast temperature reduction, low cost, large waste water amount, no odor reduction, tar-containing generation of corrosive sulfurous acid, high waste water treatment cost and far more defects than the advantages. This embodiment initiates the steam tar removal technique, and steam mixes in the pipeline with the high-temperature waste gas that contains tar with accurate proportion, adopts the heat exchanger of two kinds of velocity of flow of height of special design, and rapid cooling and constant temperature mode again fully prevent that tar from taking place because of the change of consistency and particulate matter bonding scale deposit in the cooling process, and constant temperature tar is the special collector of liquid inflow. After passing through the oil-water separator, the problem of tar in the waste gas is solved. No large amount of additive wastewater is generated in the production. The purified combustible gas is deacidified, whitened and stored under a constant pressure, and then enters a thermal cracking kettle 84 heating combustion system for secondary recycling. Therefore, the secondary energy utilization of tar and combustible gas in the anaerobic thermal radiation carbonization treatment process of the household garbage is realized, the high-heat mixed waste gas is purified in a segmented mode, the secondary energy is combusted and utilized in a zero-discharge mode, all resource utilization, harmless treatment and zero-discharge production of the household garbage are completely realized, compared with the traditional technology, a large amount of waste water generated by natural cooling pipe blockage of a pipeline and a spraying method is fundamentally and effectively avoided, and the waste water solves the defects of high cost, coking, blockage, explosion and the like in direct discharge cooling. Meanwhile, the odor treatment abandons the process technology of deacidification, decoking and dust removal by the traditional spraying method to generate a large amount of wastewater and waste resources and the advanced dry deacidification and decoking technology (mixed calcium tar powder needs to be burnt by a furnace and waste cloth bags need to be treated), innovatively adopts a waste heat rotary kiln drying and dehydration technology, a biological filter bed technology, a UV photolysis and high-energy plasma oxidation technology and other deodorization technologies to carry out combined odor removal, realizes the decoking and dust removal purification, waste heat utilization and odor retreatment of high-temperature odor discharged from the garbage final treatment thermal cracking kettle 84, finally realizes that the discharged gas reaches the national standard, and realizes the full zero discharge of solid, liquid and gas in the whole process.
