How to treat organic wastewater
Thread Content
At a concentration of around 10%, how can the total levels of COD and ammonia nitrogen be reduced?
High-concentration organic wastewater can be treated by incineration
Highly efficient biological treatment techniques can be used, which rely on the degradation action of specific microorganisms; this approach can generally reduce COD levels to below 1000. However, the data you have provided is insufficient – at least the conventional parameters need to be given, as well as information regarding salt concentration requirements.
What was said on the 4th floor is right! Generally speaking, for such high COD levels as you mentioned, biochemical treatment methods should be considered, but first it is necessary to assess the biodegradability of the substance, which requires testing first. Then, depending on the actual situation, UASB or anaerobic digestion can be used; or flocculants can be applied first followed by biochemical treatment. You can send the detailed information first, and we’ll take a look.
Aerobic biological treatment: COD removal rate as high as 90%
I’m sorry I wasn’t clear enough; it’s actually ammonium adipate and adipic acid buffer, with 1%-2% ammonium hydrogen phosphate added. There may also be trace amounts of Al ions, alumina, etc. Since it’s an organic substance, its biodegradability is good, and COD removal is significant, but the effects on ammonia nitrogen and phosphorus aren’t very noticeable. The treatment level of 2nd-grade discharge standards is sufficient (if that’s not possible, 3rd-grade standards will work as well; beyond that, wastewater treatment plants won’t accept it)
Just to add, it’s something like pH 6-7
The concentration is quite high! Burn and adsorb it; it’s definitely not possible to just discharge it!
The concentration is around 10%. How can the total levels of COD and ammonia nitrogen be reduced? The concentration value isn’t clear; what are the respective concentrations of COD and ammonia nitrogen?
Bro, how could it be any clearer? I’m telling you that ammonium adipate and adipic acid are basically neutral; I believe anyone in this field would understand this
A 10% organic content is too high; distillation separation or other separation methods can be considered to extract the organic substances, thereby recovering them and addressing environmental pollution – achieving two goals at once.
