Abstract

Et sjøvannavgassavsvovlingssystem er i stand til å oksidere avløpsvann med høy effektivitet over en kort tid som unngår en ekstrem reduksjon i konsentrasjonene av svovelsyrling-baserte materialer i avløpsvannet utsluppet fra en sjøvannavgassavsvovlingsanordning og en reduksjon av avløpsvannets pH pga. oksidasjonsbehandlingen. Sjøvannavgassavsvovlingssystemet har et avsvovlingsabsorpsjonstårn 17 som anvender sjøvann som en absorberende løsning og en avløpsvannoksidasjonstank 20 som oksiderer svovelsyrling-baserte materialer inneholdt i avløpsvannet utsluppet fra avsvovlingsabsorpsjonstårnet. I avløpsvannoksidasjonstanken 20 innføres luft trinnvis i avløpsvannet inneholdende de svovelsyrling-baserte materialene gjennom minst to trinn av luftinntakdyser 33, som derved oksiderer de svovelsyrling-baserte materialene i avløpsvannet, og sjøvann innføres trinnvis i avløpsvannet gjennom minst to trinn av sjøvanninjeksjonsporter 26 i takt med den trinnvise oksidasjonsprogresjonen, som derved fortynner avløpsvannet.A seawater desulphurisation system is capable of oxidizing high-efficiency wastewater over a short period of time, avoiding an extreme reduction in the concentrations of sulfuric acid-based materials in the wastewater discharged from a seawater desulfurization device and a reduction of the wastewater pH. oxidation treatment. The seawater desulfurization system has a desulfurization absorption tower 17 which uses seawater as an absorbent solution and a wastewater oxidation tank 20 which oxidizes sulfuric acid-based materials contained in the wastewater absorbed from the desulfurization absorption tower. In the wastewater oxidation tank 20, air is introduced stepwise into the wastewater containing the sulfuric acid-based materials through at least two stages of air intake nozzles 33, thereby oxidizing the sulfuric acid-based materials in the wastewater, and seawater is introduced stepwise into the wastewater effluent 26 at least twice. stepwise oxidation progression, thereby diluting the wastewater.
