Uguqulo lwaManzi kunye naManzi amdaka
Ukucocwa kogutyulo yinkqubo esusa uninzi lwezinto ezingcolisayo kumanzi amdaka okanye ilindle kwaye ivelise zombini ulwelo olufanelekileyo olulungele ukulahlwa kwindalo esingqongileyo kunye nodaka.Ukuze kusebenze, ugutyulo lwelindle kufuneka luhanjiswe kwindawo yokucoca ngemibhobho efanelekileyo kunye neziseko ezingundoqo kwaye inkqubo ngokwayo kufuneka ixhomekeke kulawulo nolawulo.Amanye amanzi amdaka afuna iindlela ezahlukeneyo zokucocwa ngamanye amaxesha ezikhethekileyo.Kwelona nqanaba lilula lonyango lwelindle kunye namanzi amaninzi alahlwayo kungokwahlulwa kwezinto eziqinileyo kulwelo, ngokwesiqhelo ngokuhlaliswa kwazo.Ngokuguqula ngokuthe ngcembe imathiriyeli enyityilisiweyo ibe sisiqina, ngokuqhelekileyo umhlambi webhayoloji kunye nokulungisa oku, umlambo okhulayo wobunyulu uyaveliswa.
Inkcazo
Ugutyulo yinkunkuma engamanzi evela kwizindlu zangasese, iibhafu, iishawara, iikhitshi, njl. njl. elahlwa ngemijelo ephantsi komhlaba ehambisa amanzi amdaka.Kwiindawo ezininzi ilindle likwaquka inkunkuma engamanzi evela kushishino nakurhwebo.Kumazwe amaninzi, inkunkuma ephuma kwizindlu zangasese ibizwa ngokuba yinkunkuma emdaka, inkunkuma ephuma kwizinto ezifana nezitya, iibhafu namakhitshi abizwa ngokuba ngamanzi amdaka, kwaye inkunkuma yemizi-mveliso neyezorhwebo ibizwa ngokuba yinkunkuma yorhwebo.Ukwahlulwa kwamanzi asekhaya aphuma kumanzi angwevu kwaye amanzi amnyama aya exhaphake kakhulu kumazwe aphuhlileyo, namanzi angwevu avunyelwe ukuba asetyenziselwe ukunkcenkceshela izityalo okanye aphinde asetyenziswe ukugungxula izindlu zangasese.Ugutyulo oluninzi lukwaquka namanzi angaphezulu asuka kuphahla okanye kwiindawo eziqinileyo.Amanzi amdaka kamasipala ke ngoko abandakanya ukulahlwa kwenkunkuma yolwelo kwindawo yokuhlala, yorhwebo, kunye nolwemizi-mveliso, kwaye anokubandakanya ukuhamba kwamanzi esiphango.
Iiparamitha zivavanyiwe ngokubanzi:
• BOD (Imfuno yeOxygen yeBiochemical)
•COD (iMfuno yeOxygen yeChemical)
•I-MLSS (Iziqina Ezixutyiweyo Zotywala)
•Ioli kunye neGrisi
•pH
•Ukuqhuba
•Iziqina ezinyibilikileyo zizonke
I-BOD (Imfuno ye-Oxygen yeBiochemical):
Imfuno yeoksijini yebhayoloji okanye iBOD sisixa seoksijini enyityilisiweyo efunwa yi-aerobic biological organisms kumzimba wamanzi ukuqhekeza imathiriyeli ephilayo ekhoyo kwisampulu yamanzi enikiweyo kubushushu obuthile ngexesha elithile.Eli gama likwabhekiselele kwinkqubo yekhemikhali yokumisela le mali.Olu ayilovavanyo lobungakanani obuchanekileyo, nangona lusetyenziswa ngokubanzi njengesalathiso somgangatho wendalo wamanzi.I-BOD ingasetyenziswa njengegeyiji yokusebenza kwezityalo zokucocwa kwamanzi amdaka.Idweliswe njengongcoliseko oluqhelekileyo kumazwe amaninzi.
I-COD (iMfuno ye-Oxygen yeKhemikhali):
Kwimichiza yokusingqongileyo, uvavanyo lwemfuno yemichiza yeoksijini (COD) luqhele ukusetyenziswa ukulinganisa ngokungangqalanga ubungakanani bemixube ephilayo emanzini.Ukusetyenziswa okuninzi kweCOD kumisela ubungakanani bongcoliseko lwendalo olufumaneka kumanzi angaphezulu (umz. amachibi nemilambo) okanye amanzi amdaka, oko kwenza iCOD ibe ngumlinganiselo oluncedo wobulunga bamanzi.Oorhulumente abaninzi bamisela imimiselo engqongqo ngokuphathelele eyona mfuno iphezulu yemichiza yeoksijini evumelekileyo kumanzi amdaka ngaphambi kokuba abuyiselwe kwimekobume.
