| titleOfInvention | Ammonium removal apparatus and method using chemical treatment of wastewater generated by dehydrating digested sludge |
| abstract | Disclosed are: an ammonium removal method for removing ammonium, by means of a chemical treatment process, from a dehydrated filtrate of digested sludge discharged from an anaerobic digestion facility, which treats organic waste so as to convert same into sludge (microorganisms); and an apparatus to be used in the method, the method comprising: a) a first step of converting a bicarbonate (HCO3 -) in the dehydrated filtrate into carbonic acid (H2CO3) and removing same; b) a second step of converting an ammonium ion (NH4 +) in the dehydrated filtrate, having passed through the first step, into gaseous ammonia (NH3) and discharging same; and c) a third step of neutralizing the dehydrated filtrate having passed through the second step. When using chemical treatment comprising acidification, alkalinization and neutralization, high chemical treatment efficiency, that is, ammonium removal efficiency, can be implemented while optimizing the amount of chemicals to be consumed, and the efficiency of biological treatment of wastewater in the latter part thereof can also be greatly enhanced. |
