Process principle

云南十一选五 The odor is decomposed into a non-toxic and harmless simple inorganic substance by a moist, porous, nutrient-rich and active microbial filter layer, which utilizes the biofilm to adsorb, absorb and degrade the malodorous substance. The biofilter unit is suitable for low to medium odor environments. The biological deodorization process is mainly carried out in three steps:

1) Extracellular adsorption: When passing through a bio-filler, the malodorous substance is adsorbed by the highly functional microorganisms attached to the surface of the filler and the extracellular polymers and enzymes produced by the metabolism.
(2) Bioabsorption: The odorous substance adsorbed on the surface of the microorganism is transported into the body of the microorganism.
(3) Biological oxidation: Deodorant substances are decomposed into non-toxic and harmless water, carbon dioxide or inorganic salts in the metabolic cycle of microorganisms. Organic fillers provide inorganic salts, minerals and some carbon sources to microorganisms to promote microbial Reproduction.

Process characteristics

Good purification effect
Low energy consumption and low cost
Environmentally friendly, no secondary pollution

Simple operation and low maintenance workload
Odor treatment occasions using medium and low concentration odors of various air volumes

Process flow

The odor from the collection system enters the prewash basin through the fan, washes away some of the water soluble material and dust, and regulates the gas temperature. After sufficient pre-washing odor enters the biological filter, the microbial filter layer adsorbs, absorbs and degrades the malodorous substance, and decomposes into a gas that meets the discharge standard, and is discharged into the atmosphere through the exhaust port.

Application field

It can handle a variety of organic and inorganic waste gases and has high impact load resistance. Applicable to municipal sewage treatment plants, pumping stations, sanitation (including garbage collection, leachate, transfer station), light industry and daily chemical industry, printing and dyeing wastewater plant, petrochemical wastewater plant, hospital wastewater plant, chemical plant, sludge treatment plant, etc.
