Malodorous gas treatment - ozonation

         Foul gas mainly composed of ammonia, hydrogen sulfide, mercaptans, sulfides, phenols, amines, amides, indole, alkanes, alkenes, alkynes, aromatic hydrocarbons, alcohols, aldehydes, ketones and organic acids, wherein the amount of ammonia , followed by the hydrogen sulfide (hydrogen sulfide odor greatest contribution), the design of these components are part of an important consideration. Comprehensive comparative study of acid absorption, bases and neutral absorption absorption absorption characteristics of the compound according to the above characteristics of the exhaust gas, the use of ozone (oxidation) chemical absorption process as waste pretreatment process, ozone is a potent oxidant neutral chemical absorption and goes pollution, oxidation reduction of oxygen (02) and water (H2O), low volatility. Chemical absorption part of the application concentration of 1 to 10% (mass) of ozone gas, if the water temperature can be appropriately added to improve the ozone oxidation. Ozone oxidation of ammonia removal by 90% and 50% of hydrogen sulfide removal. The chemical absorption (oxidation) after the stench of exhaust gas, ammonia, hydrogen sulfide lot lower, then the stench of exhaust gas is low concentrations of hydrogen sulfide and organic components, through a lot of data collection and analysis, in order to further reduce the low concentration of malodorous odor , while adsorption method can also be used for further processing foul gas is an effective method. Only need to set the appropriate exhaust pipes and exhaust impetus to malodorous gases through the deodorizing device exploded purification, without adding any substance involved in a chemical reaction. Odor of ozone in water is extremely effective. Water pollution caused by industrial odor substances in addition to outside, can also cause soil microbial smelly, musty, smelly and other algae. According to microbiological research, water aerobic actinomycetes to generate musty; due actinomycetes produce antibiotics that bacteria die and stink. The results show that emit smelly substance is water soil microbial metabolites, named geosmin (C 12 H 18 O 22), a compound known issue moldiness mucidune (C 12 H 18 O 2), odor, etc., add 4.8 ppm ozone, odor of 50 degrees can become odorless, adding in a small experimental device 2 ppm ozone, can smell from 20 down to 0 degrees. There are tests proved below 25 degrees in the removal of odor, ozone injection rate of 0.1-1.5 ppm.

Odor removal methods that can be used:

  1, malodorous gas source can be a simple single ozone oxidation (Zhongshan feed processing into a unified enterprise using our four sets of special ozone gas purification equipment)

  2, Ozone + Activated Carbon Adsorption: Ozone is a potent oxidant, oxidation malodorous gases but can also open up the carbon micro air play, activated carbon adsorption capacity to improve and prolong life, saving replacement costs. (Zhaoqing Lake Technology Sewage Plant Odor Treatment)

  3, ozone (oxidation) chemical absorption - carbon fiber adsorption - oxidation - aeration activated sludge (for sewage treatment plants, but can be used after the end of combustion, but more energy.)

By the above method can efficiently remove volatile organic compounds (VOC), inorganic substances, hydrogen sulfide, ammonia, mercaptans and other major pollutants, and various odor, deodorization efficiency up to 99%, much higher than the deodorizing effect National 1993 emission standards promulgated by the stench (GB14554-93).
