Ngophuhliso loqoqosho lwasemaphandleni nokwanda kwabantu, ukukhutshwa kwamanzi amdaka asekhaya asemaphandleni nako kuyanda. Ukuze kukhuselwe okusingqongileyo kwasemaphandleni kunye nempilo yabantu, kufuneka kwakhiwe izibonelelo zonyango lwamanzi amdaka ukuze kulungiswe amanzi amdaka asekhaya asemaphandleni. Izixhobo ezihlanganisiweyo zesityalo semanzi amdaka sasezidolophini zivele ngexesha lembali, ukuba inkqubo yaso yokusebenza iyafana nendlela, namhlanje.
Izixhobo ezidityanisiweyo zesityalo sokunyanga amanzi amdaka sasezidolophini zisebenzisa inkqubo yonyango lwebhayoloji ye-AO ukususa ungcoliseko lwezinto eziphilayo kunye ne-ammonia nitrogen. Umgaqo wayo osebenzayo ukwiklasi A, ngenxa yobuninzi bezinto eziphilayo kwi-sewage, ii-microorganisms zikwimeko ye-hypoxia, ngeli xesha, ii-microorganisms zii-facultative microorganisms, ziya kubolisa i-nitrogen yendalo kwi-sewage ziye kwi-NH?-N, ngelixa zisebenzisa umthombo we-carbon yendalo njengomnikeli we-electron, i-NO?-N、NO?-N iguqulwa ibe yi-N? Kwaye kusetyenziswa eminye yemithombo ye-carbon yendalo kunye ne-NH?-N ekwenzeni izinto ezintsha zeseli.
Ngoko ke, ichibi leklasi A lezixhobo zonyango lwelindle ezidibeneyo alinamsebenzi othile wokususa izinto eziphilayo kuphela, linciphisa umthwalo we-organic wetanki ye-aerobic elandelayo, evumela i-nitrification, kodwa likwaxhomekeke kuxinzelelo olukhulu lwezinto eziphilayo ezikhoyo emanzini aluhlaza ukuze ligqibezele i-denitrification, kwaye ekugqibeleni lisuse ungcoliseko lwe-nitrogen eutrophic.
Kwiklasi ye-O, kuba uxinano lwezinto eziphilayo luncitshisiwe kakhulu, kodwa izixhobo zonyango lwelindle ezidibeneyo zisenomlinganiselo othile wezinto eziphilayo kwaye kukho i-NH?-N ephezulu. Ukuze kwenziwe ukubola kwe-oxidation kwezinto eziphilayo, kwaye xa kugqityiwe i-carbonization, amandla e-nitrification aqhubeka kakuhle, itanki ye-aerobic biological contact oxidation enomthwalo ophantsi wezinto eziphilayo ibekwe kwinqanaba le-O.
Iintsholongwane ze-aerobic kunye neebhaktheriya ezizi-oxygenic zikho ikakhulu kwiklasi ye-O-pool yezixhobo zonyango lwendle ezidibeneyo. Ngaba iintsholongwane ze-aerobic zibolisa izinto eziphilayo zibe yi-CO? Kwaye i-H? O, i-Inorganic carbon okanye i-CO emoyeni? Njengomthombo wezondlo, ngaba i-NO kwi-sewage?-N、NO?-N iya kuba yi-N?. Ukungcola kwe-O pool kugeleza kwi-A pool, kubonelela nge-electron receiver ye-A pool, kwaye ekugqibeleni kuphelise ungcoliseko lwe-nitrogen ngokusebenzisa i-denitrification.
Izixhobo ezidityanisiweyo zezityalo zokunyanga amanzi amdaka zasezidolophini kwiindawo ezahlukeneyo kufuneka zikhethe iteknoloji efanelekileyo yokunyanga amanzi amdaka ngokwemeko ethile yeendawo zasemaphandleni, kwaye kufuneka ziqwalasele nokuba le teknoloji inokwenzeka na, iqoqosho kunye nempembelelo yokusingqongileyo. Izixhobo zokunyanga amanzi amdaka ezidityanisiweyo zeJiading zingahlangabezana neemfuno zokucoca amanzi amdaka ezidityanisiweyo ezingama-10,000 eetoni ezili-0.3, kwaye uthotho lweemveliso ezili-9 lunokukhethwa ngokukhululekileyo, ngokweemeko ezahlukeneyo.
