There are many kinds of odorous substances and they come from a wide range of sources. They affect the human respiratory system, digestive system, cardiovascular system, endocrine system, and nervous system to varying degrees. The odor of rubbish is caused by the decomposition of organic components in the rubbish by bacteria.
The organic matter in the living garbage mainly includes peel, leafy vegetables stems, leftovers, poultry, animal and fish skins, hairs, internal organs, fats, excrement, leaves, waste paper, flowers and animals, etc., and certain moisture. In the process of natural digestion, under the influence of aerobic anaerobic fermentation, malodors are produced. Especially when the weather is hot, the odor becomes more serious due to the acceleration of fermentation. The odor of domestic garbage is ammonia, and vulcanization occurs. Hydrogen, organic amines, organic sulfur, volatile fatty acids, etc.
The methods of deodorization of household waste are as follows: 1. Liquid-gas reaction method of plants: effectively removes waste odors and suppresses the generation of odors, and has a long duration of action, allowing organic wastes to be quickly decomposed organically, combining the odor molecules With the principle of phase brake, it quickly decomposes and removes waste odor while inhibiting the generation of various odors such as hydrogen sulfide, mercaptans, volatile fatty acids and ammonia. Features: professional, fast and efficient, cost-effective, safe and environmentally friendly, no secondary pollution.
2. Microbiological method: The ability to use microorganisms to degrade organic substances into their own required nutrients. Applicable objects: Odorous organic substances. Characteristics: Smell odor spills in solids and liquids can be inhibited, but it is difficult to emit odors. Play a role, occupy a wide area, high investment, operation and management trouble.
3. Adsorption method: The use of porous media for the adsorption of odorous molecules. Applicable objects: Hydrocarbons, alkali-acidic odor molecules. Features: Simple equipment, good deodorization effect, suitable for the treatment of low-concentration odor gases, generally used for compound odor The last stage of purification, when the gas concentration is high, the gas needs to be pretreated by washing, pickling, caustic washing, etc. The gas with high dust content needs to be first dust-removed, which will cause secondary pollution.
5. Plasma method: plasma method, relying on molecular exciter, using high frequency, high pressure, using the principle of molecular resonance. Applicable objects: odor components that are easily decomposed, odor gases with unstable molecular structure. 6. Odor masking method: Obscured, covered with other strong gases odor, but can not remove the odor components.
Garbage and deodorization equipment is suitable for places with garbage and odor exhaust gas, such as garbage rooms, residential garbage transfer stations, landfills, slaughterhouses, feed mills, and farms.
