Uthini umahluko phakathi kwonyango lwamanzi angcolileyo?

Okwangoku, ngokutsho kweengcali, kukho ezininzi ezininzi, kwaye ezibaluleke kakhulu, iindlela zokusetyenziswa kwamanzi, eziquka i-biological, chemical and mechanical.

Kule nqaku, siza kuqwalasela ngokubhekiselele kulo mbuzo njengonyango lwe-biological yamanzi angcolileyo. Kule mihla yinto ethandwa kakhulu kwaye ngexesha elifanayo lisebenza.

Utyando lwamanzi angcolileyo lwe-Biological luqhutyelwa kuphela kulunye uhlobo lwezityalo zonyango lwamayeza-okubizwa ngokuba yindlela yokuzikhusela kwamanzi. Kakade ke, le ndlela iyingqungquthela, isekelwe ekusetyenzisweni kweebhaktheriya ezikhethekileyo, eziza kutshabalalisa i-organic compounds kwi-carbon kunye namanzi.

Kubalulekile ukuqaphela ukuba ii-microorganisms ezisetyenziswe kule ndlela, zahlula ngokwahlukileyo zibe ngamaqela amancinci amabini: i-aerobic kunye ne-anaerobic. Uhlobo oluphambili lwalo kukuba kwiintlobo zokuqala, amanzi atyebile e-oxygen ayadingeka. Kwimeko yesibini, ubukho be-O ₂ abukho mfuneko.

Ukuphathwa kwamanzi angcolileyo?

Okokuqala, emva kokufumana inkunkuma kwisikhululo esikhethekileyo, bahlala ixesha elide, kubangele kwinkqubo yokuvumba nokucaciswa.

Kwinqanaba elilandelayo, sele sele kucacisiwe amanzi angena kwelinye ikamelo, apho inqubo yokusebenza kwe-aeration bubble eqhubekayo eyenzekayo.

Kwinqanaba lokugqibela, ukucocwa kokugqibela kwenzeka ngenxa yobuninzi be-silt, sele sele buzaliswe kwisimo se-oxygen.

Kubalulekile ukukhumbuza ukuba unyango lwezinto eziphilayo lwamanzi angcolileyo lubhekisela ekungabikho ngokupheleleyo kwezinto ezimnandi. Ngokutsho kweengcali, le ndlela inexesha elininzi elihle, apho kubalulekile ukuphawula ukuba kungenzeka ukusetyenziswa kwakhona kwamanzi. Kodwa kulo mzekelo sele sele uphathwe ngamanzi okuphambi kwangaphambili kunokusetyenziswa kuphela kwiinjongo zoqoqosho, umzekelo, ukuthambisa izityalo.

Ngakolunye uhlangothi, unyango lwamanzi acoceko luthandwa ngokufanayo. Le ndlela idlalwa ngokusetyenziswa kweendlela ezintathu: ukungathathi hlangothi, i-oxidation kunye nokunciphisa. Ngokuqinisekileyo, esi sicombululo siphumelele kakhulu, nangona kunjalo, ngenxa yeendleko eziphezulu ze-electrochemical oxidation, isetyenziswa kakhulu.

Ekupheliseni, ku funeka kuqatshelwe ukuba ngoku, umbuzo onjalo njengonyango lwamanzi angcolileyo kunye nophatho lwamanzi angcolileyo lubonwa njengento efanelekileyo. Ngaphandle koko, ukuba wonke umntu angcolise uluntu, kuluntu olusondeleyo lijongene neentlekele eziphilayo ezimbi. Ngaphezu koko, xa usebenzisa, umzekelo, indlela yezinto eziphilayo, wonke umntu unelungelo, njengoko sele likhankanywe ngasentla, ukuphinda usetyenzise kwakhona amanzi afunyenweyo ngenjongo zoqoqosho, ebonisa ukulondolozwa kwemithombo yendalo. Sekudlulileyo namhlanje, iingcali zivakalisa i-alamu kwaye zikhuthaza ukuba zisebenzise indlela ye-biological, eyona nto ifanelekileyo kwaye isisombululo esifanayo.
