Description
Technical Field
The invention relates to a microbial waste gas purification device, and belongs to the technical field of waste gas purification treatment.
Background
With the development of economy, the problem of exhaust pollution such as malodor has been more and more emphasized. Taking malodorous gases as an example, the malodorous gases can be divided into two main categories: one is an organic pollutant gas and the other is an inorganic gas. The organic pollution gas mainly comprises hydrocarbons and thiols, and the inorganic gas mainly comprises sulfide, ammonia compounds and the like. The gases have the characteristics of complex components and high treatment difficulty, and particularly some long-chain macromolecular substances have poor water solubility and are difficult to biodegrade. With the further research and development of microorganisms in the field of pollution control, the utilization of microorganisms has deeper research and practice in the aspect of treating air pollutants, and the main principle of purifying air by a microbial method is to degrade harmful substances in the air by utilizing the assimilation of a microbial population which is widely distributed, vigorous in metabolism, rapid in propagation and beneficial to application, so as to achieve the purpose of purifying the air. The technical scheme adopted by the prior art is as follows: waste gas enters the purifier from the middle air duct on the side surface of the purifier, and high-efficiency biological fillers with basically consistent thickness are paved on the upper layer and the lower layer of the air inlet duct. After entering the purifier, the waste gas is divided into two parts for simultaneous treatment. One part is purified simultaneously by the filler on the upper layer of the air inlet duct and the other part is purified simultaneously by the filler under the air inlet duct, so that the effects of one air inlet, simultaneous biological treatment of the two layers of fillers and simultaneous air exhaust after treatment are achieved. The function of the equipment is equivalent to that of the traditional two-stage equipment. Because only one air inlet is provided, two layers of air outlets are processed simultaneously, thus greatly reducing the occupied area of the equipment. Meanwhile, the contact area of the waste gas and the biological filler is greatly increased due to the large area of the filler, so that the treatment efficiency of the equipment can be greatly improved. Meanwhile, the ventilation area is large, and the air outlet is large, so that the resistance of waste gas passing through the equipment can be obviously reduced. The upper and lower two layers of fillers are fixed with high-efficiency strains for specially treating the waste gas. When the waste gas passes through the filler, a large number of microorganisms on the filler can capture and transmit pollutants in the waste gas into biological cells for degradation and purification, the pollutants are converted into nontoxic, odorless and harmless substances, such as carbon dioxide and water, and the purified waste gas is discharged to the atmosphere.
Although the prior art improves the gas purification effect to a certain extent, the prior art does not have good temperature control for microbial growth and metabolism, the temperature of the environment is required, the optimal effect of microbial purification can be exerted only at the optimal temperature, when a large amount of gas passes through, harmful components in the gas are difficult to be completely purified, and the discharged gas contains a large amount of moisture and strains, so that the waste gas treatment effect is inevitably reduced. For this reason, a corresponding technical scheme needs to be designed for solution.
