<span style="font family: Song typeface; In the sludge stacking and compression workshop, foul odors are generated, mainly composed of gases such as hydrogen sulfide, ammonia, alcohols, and hydrocarbons, which are extremely complex; If directly discharged, it will affect the physical and mental health of surrounding residents.

Sludge odor components

Most of the odorous substances in the sludge separated from sewage come from anaerobic biological reactions that consume organic matter, sulfur, and nitrogen. Municipal sewage sludge contains sufficient organic sulfur and inorganic sulfates, leading to the generation of odors. Its odorous gases are divided into organic gases and inorganic gases. Inorganic gases are mainly hydrogen sulfide and ammonia, while organic gases are a variety of extremely complex odorous substances produced during the degradation of organic matter, including indole, skatole, thiols, and amines.

Activated carbon adsorption scheme

When pharmaceutical waste gas enters the adsorption box and enters the activated carbon adsorption layer, due to the presence of unbalanced and unsaturated molecular attraction or chemical bonding forces on the activated carbon adsorption surface, when the surface of the activated carbon adsorbent comes into contact with gas, it can attract gas molecules, causing them to concentrate and remain on the solid surface. This phenomenon is called adsorption. By utilizing the adsorption capacity of activated carbon adsorbent surface, the exhaust gas is brought into contact with the porous activated carbon adsorbent on the large surface. The pollutants in the exhaust gas are adsorbed on the surface of the activated carbon, separated from the gas mixture, and the purified gas is discharged at high altitude.

scope of application

Activated carbon adsorption technology is widely used in industries such as petroleum, chemical, rubber, coating, printing, electronics, pharmaceuticals, textile printing and dyeing, food, furniture, coating, plastics, feed, leather, machinery, semiconductor manufacturing, and material synthesis for low concentration and high air volume waste gas treatment.

UV Photolysis Purification Solution

UV photolysis waste gas treatment technology refers to the use of high-energy UV beams to decompose oxygen molecules in the air, producing free oxygen (i.e. reactive oxygen species). Due to the imbalance of positive and negative electrons carried by free oxygen, it needs to combine with oxygen molecules to produce ozone, which has strong oxidizing properties. Through the synergistic photolysis and oxidation of organic waste gas and odorous gases by ozone, organic waste gas and odorous gases are degraded and converted into low molecular compounds, water, and carbon dioxide.

FEATURES

(1) Efficient Odor Removal: It can efficiently remove major pollutants such as volatile organic compounds (VOCs), inorganic substances, hydrogen sulfide, ammonia, thiols, and various odorous gases, with a deodorization efficiency of over 95%. The deodorization effect exceeds the national odor pollutant emission standard (GB14554-93) issued in 1993 and the comprehensive emission standard of atmospheric pollutants (GB16297-1996) issued in 1996.

No pre-treatment required: Organic gases do not require special pre-treatment, such as heating, humidification, etc. The equipment can work normally in an environment with a temperature between -30 ℃ and 95 ℃, humidity between 30% and 98%, and pH value between 2-11.

(2) No need to add any substances: just set up corresponding exhaust pipes and exhaust power, so that odorous gases and industrial waste gases can be deodorized, decomposed and purified through UV photolysis waste gas purification equipment, without adding any substances to participate in chemical reactions.

(3) Strong adaptability: It can adapt to the deodorization and purification treatment of low to medium concentrations and different industrial waste gases, and can work continuously 24 hours a day, with stable and reliable operation.

(4) Low operating cost: no mechanical action, no noise, no need for dedicated management and daily maintenance, only regular inspections are required, low equipment energy consumption, low equipment wind resistance<50pa, can save a lot of exhaust power energy consumption.

(5) Safe and reliable: Due to the use of photolysis principle and explosion-proof treatment of the module, safety hazards are eliminated, and the fire, explosion, and corrosion resistance are high. The equipment performance is safe and stable, especially suitable for industries with high explosion-proof requirements such as oil (gas) fields, petrochemicals, and pharmaceuticals.
