Ngokuthuthuka komnotho wasemakhaya kanye nokwanda kwabantu, ukuthuthwa kwendle yasemakhaya nakho kuyanda. Ukuze kuvikelwe imvelo yasemakhaya kanye nempilo yabantu, kudingeka kwakhiwe izindawo eziningi zokuhlanza indle ukuze kuphathwe indle yasemakhaya yasemakhaya. Imishini ehlanganisiwe yesitshalo sendle sasedolobheni ivele ngesikhathi somlando, ukuthi inqubo yayo yokusebenza injani ngempela, namuhla.
Imishini ehlanganisiwe yesitshalo sokwelapha indle sasedolobheni isebenzisa kakhulu inqubo yokwelapha ye-AO biological ukususa ukungcola okungokwemvelo kanye ne-ammonia nitrogen. Isimiso sayo sokusebenza sisesigabeni A, ngenxa yokugcwala okuphezulu kwezinto eziphilayo emanzini angcolile, izinto ezincane zisesimweni se-hypoxia, ngalesi sikhathi, izinto ezincane ziyizinto ezincane ezikwazi ukukhiqiza, zizobola i-nitrogen engokwemvelo emanzini angcolile zibe yi-NH?-N, kuyilapho zisebenzisa umthombo wekhabhoni ephilayo njengomnikeli we-electron, i-NO?-N、NO?-N iguqulwa ibe yi-N? Futhi kusetshenziswa eminye yemithombo yekhabhoni ephilayo kanye ne-NH?-N ekuhlanganiseni izinto ezintsha zeselula.
Ngakho-ke, ikilasi A lemishini yokwelapha indle ehlanganisiwe aligcini nje ngokuba nomsebenzi othile wokususa izinto eziphilayo, linciphisa umthwalo wezinto eziphilayo wethangi le-aerobic elilandelayo, elihambisana ne-nitrification, kodwa futhi lithembele ekugxilweni okuphezulu kwezinto eziphilayo ezikhona emanzini angavuthiwe ukuze kuqedwe i-denitrification, futhi ekugcineni liqede ukungcola kwe-nitrogen eutrophic.
Ekilasini le-O, ngoba ukugcwala kwezinto eziphilayo kuncishisiwe kakhulu, kodwa imishini yokwelapha indle ehlanganisiwe isenenani elithile lezinto eziphilayo futhi kukhona i-NH?-N ephezulu. Ukuze kwenziwe ukubola okwengeziwe kwe-oxidation kwezinto eziphilayo, futhi ngaphansi kokuqedwa kwe-carbonization, amandla e-nitrification aqhubeka kahle, ithangi le-aerobic biological contact oxidation elinomthwalo ophansi wezinto eziphilayo libekwa ezingeni le-O.
Ama-microorganism e-aerobic kanye nama-bacteria azi-oxygen akhona kakhulu ekilasini le-O-pool lemishini yokwelapha indle ehlanganisiwe. Ingabe ama-microorganism e-aerobic abola izinto eziphilayo zibe yi-CO? Futhi i-H? O, i-Inorganic carbon noma i-CO emoyeni? Njengomthombo wezakhamzimba, ingabe i-NO esendle?-N、NO?-N iphenduka i-N?. Ukungcola kwechibi le-O kugeleza echibini le-A, kunikeze isamukeli se-electron sechibi le-A, futhi ekugcineni kuqede ukungcola kwe-nitrogen ngokusebenzisa i-denitrification.
Imishini ehlanganisiwe yezitshalo zokuhlanza indle zasemalokishini ezifundeni ezahlukene idinga ukukhetha ubuchwepheshe bokuhlanza indle obufanele ngokwesimo esithile sezindawo zasemakhaya, futhi idinga nokucabangela ukusebenziseka, umnotho kanye nomthelela wezemvelo wobuchwepheshe. Imishini yokuhlanza indle ehlanganisiwe yokuvikela imvelo ye-Jiading ingahlangabezana nezidingo zokuhlanza indle ezingamathani ayi-10,000 ahlanganisiwe angu-0.3, kanye nochungechunge lwemikhiqizo engu-9 lungakhethwa ngokukhululeka, ngokwezimo ezahlukene.
