Problems solved by technology

The main reasons are (1) the biodegradation rate of benzene rings and some toxic substances is limited, and it is difficult for organisms to open the chain of benzene rings, which limits the rate of biodegradation
(2) On the other hand, most organic solvents are organic compounds that are poorly soluble in water
Therefore, the rate of biodegradation is also limited by the mass transfer of hydrophobic substances from the gas phase to the liquid phase.

Embodiment Construction

[0029] The present invention will be further described below in conjunction with reality and accompanying drawing.

[0030] like figure 1 The high-efficiency biological purification system for organic waste gas of the present invention includes four parts, an oil mist separator, a UV decomposition chamber, a biological purifier, a water circulation humidification system and a surfactant adding system.

[0031] The organic waste gas enters the first-stage oil mist separator to separate the oil mist, and then decomposes through ultraviolet light to decompose the biodegradable benzene ring substances into small molecules or crack the benzene ring substances through UV. Thereby greatly improving the biodegradability of benzene ring substances. The substances decomposed by UV are then bio-degraded through biological filtration. Since organic solvents and benzene-ring organic substances are mostly hydrophobic substances that are difficult to dissolve in water, surfactants are adde...

Abstract

An efficient bio-cleaning process for organic waste gas includes such steps as oil fog separating, ultrasonic decomposing for cracking the high-molecular and benzene ring moleculae, biologic filtering for bio-degradation and bio-cleaning, adding surfactant for speeding up the transfer of hydrophilic organic substance from gas phase into liquid phase and improving the efficiency, and exhausting the treated waste gas into atmosphere. Its system is composed of oil fog separator, UV decomposing chamber, bio-cleaner, water circulating moistener and surfactant adding unit.

Description

technical field [0001] The patent of the present invention relates to a biological purification system for degrading and purifying organic waste gas in various industries by using microorganisms as the main method and physical and chemical methods as supplementary methods. This organic waste gas purification system can biodegrade the oil mist in the organic waste gas and various organic substances such as ketones, aldehydes, phenols, acids, aromatics, benzene, etc., into CO2 and water, etc., to achieve the purpose of organic waste gas purification. The purified exhaust gas is non-toxic, odorless and tasteless. Background technique [0002] The use of organic solvents is an important production link in many industries, involving a wide range of areas, such as automobile manufacturing, machining, hardware furniture, electronics, repair industry, painting process, etc. all need to use organic solvents. This also causes serious problems of organic waste gas pollution. These in...
