Urebye amakuru aherutse kugurishwa, umubare wibicuruzwa byakiriwe na Liding Environmental Protection kubikoresho bya AAO bikomeza kuba byinshi. Ni ibihe bintu bituma abakiriya bizera iki gikorwa kurushaho? Ibikurikira, Kurengera Ibidukikije bizamenyekanisha ishingiro ryibikorwa bya AAO.
Intandaro yimikorere ya AAO nugukoresha nitrification no gutandukanya ibinyabuzima mubihe bitandukanye kugirango ukureho azote, no gukoresha bagiteri zegeranya fosifore kugirango ikureho fosifore. Kubwibyo, iyi nzira irakwiriye cyane mumishinga ifite igenzura rikomeye rya azote na fosifore. Ibikorwa nyamukuru byibikoresho byo gutunganya imyanda yo mucyaro gahunda yo gutunganya AAO byibanze muburyo butatu bwo gukora, aribwo pisine ya anaerobic, pisine ya anoxic na pisine.
Mu gace ka reaction ya anaerobic, kubera kubura nitrate na ogisijeni mu mwanda w’ibikoresho byo gutunganya imyanda yo mu cyaro, fosifore ikusanya bagiteri ibika ingufu mu bintu byegeranya fosifore kandi ikarekura icyarimwe cya fosifike, mu gihe izindi bagiteri ahanini zidakora. . Muri iyi reaction module Izindi bagiteri zidakora cyane kandi bigoye gukura. Moderi ya anaerobic ikoreshwa mukugabanya COD no gutegura gukuramo fosifore.
Mu buryo bwa anoxic reaction module, imyanda y’ibikoresho byo gutunganya imyanda yo mu cyaro ifite urugero rwa nitrate idafite ogisijeni, kandi na bagiteri yanga gukoresha COD kugirango igabanye nitrate kuri azote, irekure alkali, kandi ibone imbaraga zo gukura. Kugabanya COD na azote.
Moderi ya reaction ya aerobic nigice cyibanze cyibikoresho byo gutunganya imyanda yo mucyaro. Hano, nitrifyinga bacteri oxyde ya azote ya azote kuri nitrate ya azote, ikarya alkaline na ogisijeni, PAOs ikuramo fosifore nyinshi, ikoresha ingufu muri PHAs kugirango ihuze polyphosifore, kandi OHO ikomeje gukuraho COD, PAOs, OHOs, na bagiteri nitrifingi zose zirakura. muriki gikorwa. Mugabanye COD, azote ya ammonia na fosifore.
Duhereye ku isesengura ry’ibisabwa mu mishinga yo gutunganya imyanda yo mu ngo yo mu cyaro, guhitamo uburyo bwo gutunganya imyanda bigomba kuba byujuje ibisabwa mu rwego rwo gutunganya, ibiranga imyanda, ubwiza bw’amazi meza ndetse n’amazi asohoka. Muri icyo gihe, uburyo bukwiye bwo kuvura bugomba gutoranywa ukurikije ibiranga imyanda yaho. Imanza nyinshi zerekana ko ibikoresho byo gutunganya imyanda yo mu cyaro AAO bifite imiterere ihuza n'imishinga itandukanye.
