Treatment of odors in wastewater sludge drying rooms and odorous exhaust gases released at high altitudes?
Thread Content
The sludge processed in the sludge pressing and drying unit of our company’s wastewater treatment plant emits a strong odor. Even after washing and filtering it with activated carbon, the exhaust gas still has an unpleasant smell. Are there any effective methods to deal with this issue? Thank you all, gentlemen!
Send it to the boiler room to be burned; if there is no boiler room, biological filtration can only be used. You can contact me
For malodorous gases, low-temperature plasma combined with photochemical treatment can be used; this technology is already well-developed in China, with many successful applications You might as well check it out.
What solution is used for washing: water, alkali solution, or an oxidizing agent? It is recommended to try oxidizing agents, such as hydrogen peroxide or sodium dichloroisocyanurate.
Spraying micron-sized atomized plant liquid using a spray system to break down odors is cost-effective and practical, causing no damage to equipment, people, or buildings.
Ozone machine + photolysis + low-temperature plasma process!
There are two main approaches: one is photolysis, and the other is spraying plus biological adsorption; there are mature cases for both
For those upstairs, the key is to consider two issues: equipment investment costs and operating costs. The technical process isn’t an issue; the key is whether the customer can afford it. You might want to look into nano-catalytic oxidation – there are already cases of its use in oil processing plants, battery factories, and optoelectronic companies (in the field of magnetic materials). It can replace activated carbon directly, and there is no unpleasant odor when exporting; the filter elements can remain in use for at least 3 years without needing replacement.
