Unyango lwamanzi amdaka

Uhlalutyo lwamanzi amdaka kunye namanzi amdaka
Unyango lwamanzi amdaka yinkqubo esusa uninzi lwezinto ezingcolisayo emanzini amdaka okanye amdaka kwaye ivelise ulwelo olufanelekileyo ukulahlwa kwindawo yendalo kunye nodaka. Ukuze isebenze kakuhle, amanzi amdaka kufuneka athunyelwe kwisityalo sokucoca ngemibhobho efanelekileyo kunye neziseko kwaye inkqubo ngokwayo kufuneka ilawulwe yimithetho kunye nolawulo. Amanye amanzi amdaka adla ngokufuna iindlela ezahlukeneyo zonyango kwaye ngamanye amaxesha ezikhethekileyo. Kwinqanaba elilula lonyango lwamanzi amdaka kwaye uninzi lwamanzi amdaka lukwahlulwa kwezinto eziqinileyo kulwelo, ngokuqhelekileyo ngokuhlaliswa. Ngokuguqula izinto ezinyibilikisiweyo zibe zizinto eziqinileyo, ngokuqhelekileyo umhlambi webhayoloji kwaye ulungise oku, kuvela umjelo wokungcola okhulayo wobunyulu.
Inkcazo
Inkunkuma yamanzi amdaka yinkunkuma engamanzi evela kwizindlu zangasese, kwiibhafu, kwiishawa, kwiikhitshi, njl.njl. elahlwa ngemijelo yamanzi amdaka. Kwiindawo ezininzi inkunkuma yamanzi amdaka ikwaquka nenkunkuma engamanzi evela kwimizi-mveliso nakwizorhwebo. Kumazwe amaninzi, inkunkuma evela kwizindlu zangasese ibizwa ngokuba yinkunkuma engcolileyo, inkunkuma evela kwizinto ezifana nezitya, iibhafu kunye neekhitshi ibizwa ngokuba ngamanzi amdaka, kwaye inkunkuma yemizi-mveliso neyezorhwebo ibizwa ngokuba yinkunkuma yorhwebo. Ukwahlulwa kwamanzi amdaka emakhaya kuphuma emanzini amdaka namanzi amnyama kuya kuxhaphaka kwihlabathi eliphuhlileyo, apho amanzi amdaka evunyelwa ukuba asetyenziselwe ukunkcenkceshela izityalo okanye aphinde asetyenziswe ekuhlambeni izindlu zangasese. Inkunkuma eninzi ikwaquka amanzi angaphezulu avela eluphahleni okanye kwiindawo eziqinileyo. Ke ngoko amanzi amdaka kamasipala aquka ukukhutshwa kwenkunkuma engamanzi emakhaya, ezorhwebo, kunye nemizi-mveliso, kwaye anokubandakanya ukugeleza kwamanzi esiphepho.

Iiparameters ezivavanywa ngokubanzi:

• I-BOD (Imfuno ye-oksijini yeBiochemical)

•I-COD (Imfuno yeOksijini yeKhemikhali)

•I-MLSS (Ii-Mixed Liquor Suspended Solids)

•Ioyile kunye neGreyishi

•pH

•Ukuqhuba

•Izinto eziQinisiweyo eziPheleleyo

I-BOD (Imfuno ye-oksijini yeBiochemical):
Imfuno ye-oksijini yebhayoloji okanye i-BOD sisixa se-oksijini enyibilikisiweyo efunekayo zizinto eziphilayo ze-aerobic emzimbeni wamanzi ukuze ziqhekeze izinto eziphilayo ezikhoyo kwisampulu yamanzi ethile kubushushu obuthile kwixesha elithile. Eli gama likwabhekisa kwinkqubo yekhemikhali yokumisela esi sixa. Olu asilovavanyo oluchanekileyo lobungakanani, nangona lusetyenziswa kakhulu njengophawu lomgangatho wamanzi we-organic. I-BOD ingasetyenziswa njengomlinganiselo wokusebenza kwezityalo zonyango lwamanzi amdaka. Idweliswe njengongcoliseko oluqhelekileyo kumazwe amaninzi.
I-COD (Imfuno ye-Oxygen yeKhemikhali):
Kwikhemistri yokusingqongileyo, uvavanyo lwe-chemical oxygen demand (COD) lusetyenziswa rhoqo ukulinganisa ngokungathanga ngqo ubungakanani beekhompawundi ze-organic emanzini. Uninzi lwezicelo ze-COD zimisela ubungakanani bezinto ezingcolisayo ze-organic ezifumaneka emanzini angaphezulu (umz. amachibi nemilambo) okanye amanzi amdaka, nto leyo eyenza i-COD ibe yindlela eluncedo yokulinganisa umgangatho wamanzi. Oorhulumente abaninzi babeka imithetho engqongqo malunga nemfuno ephezulu ye-chemical oxygen evumelekileyo emanzini amdaka ngaphambi kokuba abuyiselwe kwindalo esingqongileyo.
