There is a hydrogen sulfide smell around the wastewater tanks in the gasification wastewater treatment plant – how to deal with it?
Thread Content
The wastewater from gasification is sent to the wastewater tank at the sewage treatment plant; the environmental protection agency believes it has an unpleasant odor, similar to that of hydrogen sulfide. Everyone, how is it handled? The cost of adding a lid is high; I think it’s more feasible. Because hydrogen sulfide is generated during the biochemical treatment tank process. How is gasification handled at the upstream stage?
A lid can’t stop it either, right? The gas will seep through
Wastewater desulfurization uses chemicals for desulfurization. Fixed hydrogen sulfide detection instruments are installed next to the sewage tank to monitor the PPM of hydrogen sulfide in the area in real time. To prevent safety accidents,
The water obtained from gasification is stripped, but it usually flashes in a flash vaporization system; a stripping step can be added, and the gas resulting from this stripping is sent for sulfur recovery. The amount of hydrogen sulfide is likely to be very small, and at high concentrations its odor becomes imperceptible.
Please explain in detail how desulfurization and decarbonization are carried out
Is it feasible to use activated carbon for adsorption after sealing, and then discharge the substance at high altitude via a fan?
What desulfurization agent is being used? Does the hydrogen sulfide detector you have come equipped with an alarm function?
There are water-soluble desulfurization agents; both the Meisan and Saina brands can detect hydrogen sulfide in the air, and they will issue an alarm when the concentration exceeds the set PPM value. If you need such desulfurization agents or a solution, please contact me at 18675594726, Xia. Thank you
