Treatment of ammonia-containing wastewater
Thread Content
Our ammonia-containing wastewater is supposed to be sent to the sewage treatment system, but the high level of ammonia nitrogen kills the bacteria used in sewage treatment. What should we do to deal with this? Isn’t it okay to emit directly while considering environmental protection?
The ammonia is stripped out using a stripping method; if the stripping gas consists solely of ammonia, it can be recovered, while if its ammonia content is low, it can be sent to a flare for combustion before being released.
Reply to 2# 654262293: Doesn’t the gas after distillation need to be cooled as well? Even after cooling, the ammonia content in the water remains at 3% or higher, and it still cannot be treated ； If it’s not cooled, there’s still a separation tank in front of the torch; the water from there is also sent to the wastewater system, so it still won’t work.
With an ammonia content of only 3%, it can be sent directly to the flare for combustion without the need for cooling. A small amount from the separator at the torch can be sent to wastewater treatment without any problems.
How could it take so long to realize that our E1409 has very poor heat exchange performance? We really need this liquid for the gasification process right now; there’s no need to discharge it into wastewater. There’s something wrong with our design – just take a look at Jiutai’s drawings to see. Let’s go out for dinner, brother
Ammonia-containing wastewater should first undergo ammonia evaporation; the ammonia solution can be recovered as required. As for liquid ammonia, it depends on the amount of ammonia present there – it will determine what the most appropriate approach is
Using steam to produce ammonia is too difficult for making liquid ammonia; considering the production of other products instead
What you’re saying is too general. It’s recommended to first test the quality of the water coming in, to determine where the problem lies; if the ammonia level is high, it might be due to an issue with the operation of the ammonia vaporization tower；
It is recommended to use LHE polymeric hydroxycarboxylates as the circulating water treatment agent. This treatment agent operates in the presence of ammonia, and after use, the ammonia-containing wastewater can be discharged into the circulating water for treatment.
