Biological filter deodorization system

Technical Field

The utility model relates to a deodorization equipment technical field, concretely relates to biological filter deodorization system.

Background

With the development of modern science and technology, the products manufactured by industry are updated frequently, so that the waste gas and odor in industry are more and more, and the serious burden is brought to the sustainable development of China. Therefore, the environmental protection industry in China starts to be late in the aspects of waste gas treatment, deodorization treatment and other technologies, and environmental protection equipment and technologies attract national attention as early as decades ago. At present, environmental protection equipment has great development.

Taking deodorization as an example, currently common methods for odor treatment include physical adsorption, biological methods, chemical washing, ionic methods, catalytic combustion methods, deodorization by a deodorizing solution, and the like.

Physical adsorption method: the malodorous substances are adsorbed by porous media such as activated carbon, zeolite and the like, and the activated carbon is widely applied. The method has the advantages of simple process, less one-time investment, short service life of the medium (regeneration or even replacement is needed once the medium is saturated), unstable treatment efficiency and low treatment efficiency on high-concentration odor.

Chemical washing method: the chemical liquid medicine and the odor molecules are subjected to chemical reaction to generate an odorless substance so as to achieve the aim of deodorization. The method has quick effect, but high operation cost and secondary pollution.

Deodorizing with deodorizing solution: the natural plant odor removing liquid is used for absorbing odor molecules in the air and carrying out chemical reactions such as polymerization, decomposition and the like with the odor molecules so as to remove the odor. The method has the advantages of simple equipment installation, short construction period, low investment and low efficiency, and the natural plant odor removing liquid belongs to a consumable product and has high subsequent operation cost.

An ion method: high-density high-energy active ions are generated by high-frequency high-voltage electrostatic special pulse discharge, and the high-energy active ions are contacted with odor to open the chemical bonds of odor molecules and decompose into carbon dioxide and water, so that the gas is purified. The method has the advantages of relatively small volume of treatment equipment, light dead weight, suitability for occasions with compact arrangement, narrow site and the like, but higher one-time investment cost and higher operation and maintenance cost of the equipment.

A catalytic combustion method: a method for eliminating organic waste gas pollutants through thermal oxidation is characterized in that organic waste gas is catalytically combusted at the temperature of 200-500 ℃ and the residence time of 0.3-0.5 s, and is decomposed into CO2 and H2O, and the method is suitable for organic waste gas with high concentration.

The biological method comprises the following steps: the utilization is to utilize the microorganisms attached to the packing material in the reactor to degrade the pollutants in the waste gas into simple inorganic substances and microbial cytoplasm in the metabolism process. The technology has the advantages of high deodorization efficiency, thorough treatment, simple and convenient operation, no secondary pollution and low operating cost, and is called as a green deodorization technology.

The traditional biological deodorization process is to inoculate domesticated microorganisms on the surface of a filter material wrapped with a nutrient film, the microorganisms propagate by taking the nutrient film and pollutants as nutrient raw materials, and the physiological metabolic activity of the microorganisms converts the pollutants to achieve the aim of deodorization. The waste gas or odor of each pollution source is collected and then is intensively sent to the biological filter, and the waste gas or odor is humidified and dedusted, and then is absorbed by the wet, porous and active microbial filler layer, the filler and the biological membrane, and then is absorbed and degraded by the microbes in the filler, so that the pollutants are decomposed into nontoxic and harmless simple inorganic substances.
