Problems solved by technology

During the treatment process of the sewage treatment station, multi-pollutant odorous gases such as hydrogen sulfide, ammonia / trimethylamine, mercaptan / sulfide / styrene / non-methane total hydrocarbons will be produced. The composition of these gases is relatively complex and the concentration is higher than that of other municipal industries. Higher, using a single biological filter bed technology can not achieve emission standards, it is necessary to use a combination of technologies to improve purification efficiency

Embodiment Construction

[0029] The invention discloses a method for purifying malodorous gas. The malodorous gas is subjected to biological oxidation treatment after cooling, dust removal, oxidation, neutralization and absorption treatment.

[0030] The malodorous gas contacts and reacts with the oxidizing spray liquid in the oxidizing packing layer, the malodorous gas is cooled, the dust in the malodorous gas is removed, the water-soluble components in the malodorous gas are dissolved in the oxidizing spray liquid, and the Hydrogen sulfide and reducing substances are removed by oxidation reaction with the oxidant in the oxidizing spray liquid; preferably, the malodorous gas after cooling, dust removal, and oxidation is contacted and reacted with the alkaline spray liquid in the humidifying and absorbing filler layer. , the acid, alcohol, and oil components of the malodorous gas undergo a neutralization reaction with the alkaline components in the alkaline spray liquid and are absorbed and removed.

Abstract

The invention discloses an odor gas purification method and purification device. The purification device comprises a box, an air inlet, an air outlet, a first processing segment, a second processing segment, and a biological filter bed segment. The air inlet and the air outlet are arranged in different sides of the box. The first processing segment, the second processing segment, and the biological filter bed segment are arranged between the air inlet and the air outlet in sequence in the box. The first processing segment cools, dedusts, and oxidizes odor gas. The second processing segment humidifies, neutralizes, and absorbs odor gas. The air inlet, the first processing segment, the second processing segment, the biological filter bed segment, and the air outlet are communicated with eachother in sequence. The odor gas introduced into the device is cooled, dedusted, oxidized, neutralized, absorbed, and biologically oxidized, and the processed gas completely meets the discharge standards.

Description

technical field [0001] The present invention relates to the technical field of malodorous gas treatment, in particular to a malodorous gas purification method and purification device. Background technique [0002] The waste incineration plant has various storage workshops, physicochemical workshops, solidification workshops and storage tank areas. Each workshop and area will produce different amounts of waste water and waste liquid, which needs to be transported to the sewage treatment station for treatment. During the treatment process of the sewage treatment station, multi-pollutant malodorous gases such as hydrogen sulfide, ammonia / trimethylamine, mercaptan / sulfide / styrene / non-methane total hydrocarbons will be produced. These gases are relatively complex and their concentration is higher than that of other municipal industries. Higher, the use of a single biological filter bed technology cannot achieve emission standards, and it is necessary to use a combination of techn...
