Ngokukhula koqoqosho lwasemaphandleni kunye nokwanda kwabantu, ukukhutshelwa kwelindle lasemaphandleni kuyanda. Ukuze kukhuselwe okusingqongileyo emaphandleni kunye nempilo yabantu, kufuneka kwakhiwe amaziko angakumbi okucoca ilindle ukunyanga ilindle lasekhaya. Izixhobo ezidityanisiweyo zogutyulo lwamanzi amdaka ezilokishini ziye zavela ngeli xesha lembali, ukuba inkqubo yayo yomsebenzi kanye ngendlela, namhlanje ukuqonda.
Izixhobo ezidityanisiweyo zokucoca ugutyulo lwaselokishini ikakhulu zisebenzisa inkqubo yonyango lwebhayoloji yeAO ukususa ungcoliseko lwendalo kunye nenitrogen yeammonia. Umgaqo wayo wokusebenza ukwiklasi A, ngenxa yoxinzelelo oluphezulu lwezinto eziphilayo kwi-sewage, i-microorganisms zikwisimo se-hypoxia, ngeli xesha, i-microorganisms ziyi-microorganisms ezisebenzayo, ziya kubola i-nitrogen ephilayo kwi-sewage kwi-NH? -N, ngelixa usebenzisa umthombo wekhabhoni ophilayo njengomnikeli we-electron, i-NO?-N, NO?-N iguqulelwa ku-N? Kwaye usebenzisa ezinye zemithombo ye-organic carbon kunye ne-NH?-N yokwenziwa kwezinto ezintsha zeselula.
Ke ngoko, iklasi A ichibi lezixhobo zokucocwa kogutyulo oludityanisiweyo alunayo kuphela umsebenzi othile wokususwa kwezinto eziphilayo, ukunciphisa umthwalo we-organic wetanki ye-aerobic elandelayo, elungele ukuxutywa kwe-nitrification, kodwa ixhomekeke kuxinzelelo oluphezulu lwezinto eziphilayo ezikhoyo kwindawo. amanzi akrwada ukugqiba denitrification, yaye ekugqibeleni ukuphelisa ungcoliseko nitrogen eutrophic.
Kwiklasi ye-O, ngenxa yokuba i-concentration ye-organic matter iye yancitshiswa kakhulu, kodwa izixhobo zokucocwa kogutyulo oludibeneyo zisenomlinganiselo othile wezinto eziphilayo kunye ne-NH?-N ephezulu. Ukuze wenze ukubola okungaphezulu kwe-oxidation yezinto eziphilayo, kwaye phantsi kokugqitywa kwe-carbonization, amandla e-nitrification aqhubela phambili kakuhle, itanki ye-aerobic ye-biological contact oxidation kunye nomthwalo ophantsi we-organic ibekwe kwinqanaba le-O.
I-Aerobic microorganisms kunye ne-self-oxygenic bacteria zihlala zikhona kwiklasi ye-O-pool yezixhobo ezidibeneyo zokunyanga ilindle. Ngaba iimicroorganisms ze-aerobic zibola izinto eziphilayo zibe yiCO? Kwaye H? O, i-Inorganic carbon okanye i-CO emoyeni? Njengomthombo wezondlo, ingaba i-NO kugutyulo?-N, HAYI?-N iya kujika ibe ngu-N?. Amanzi amdaka echibi le-O aqukuqela ukuya kwichibi elingu-A, ebonelela ngesamkeli se-electron kwichibi elingu-A, kwaye ekugqibeleni aphelise ungcoliseko lwenitrogen ngokukhutshwa kwe-denitrification.
Izixhobo ezidityanisiweyo zemizi-mveliso yogutyulo lwamanzi amdaka ezilokishini kwiingingqi ezahlukeneyo kufuneka zikhethe ubuchwephesha bokucocwa kwelindle elifanelekileyo ngokwemeko ethile yeendawo zasemaphandleni, kwaye kufuneka kwakhona kuqwalaselwe ukuba nokwenzeka, uqoqosho kunye nefuthe lokusingqongileyo kobuchwephesha. I-Jiading ukukhuselwa kwendalo edibeneyo yokucoca izixhobo zokucocwa kwamanzi amdaka angakwazi ukuhlangabezana neemfuno ze-0.3-edibeneyo ye-10,000 yeetoni zokucocwa kwamanzi amdaka, kunye ne-9 uchungechunge lweemveliso zingakhethwa ngokukhululekileyo, ngokweemeko ezahlukeneyo.
