Yini Eyenza Udaka Lube Umsebenzi Onzima Kunamanzi Angcolile
Ithangi lodaka libukeka njengethangi lamanzi angcolile, kodwa liwumsebenzi onzima ngezindlela ezintathu ezicekela phansi ngokuthula imiklamo engacaciswanga kahle. Udaka lunzima kunamanzi angcolile ngenxa yezinto eziqinile eziphezulu, indawo yegesi ecebile nge-hydrogen sulphide, kanye nezinhlobo ezikhwishayo nezigxilile ezilumayo, konke lokhu okudinga ukumbozwa kwezindawo kanye nokuphathwa kwegesi umsebenzi wamanzi angcolile nje ongenakho.
Ukuqhathanisa umsebenzi wodaka namanzi angcolile kusho ukubona ukuthi udaka, ingxenye ehlala phansi, egxilile, engenawo umoya, lubeka izinto eziqinile, i-H2S yesigaba segesi kanye nokugqwala okukhwishayo okungatholakali emanzini angcolile agelezayo ahlanjululwe.
Izici Eziyinhloko, Izingxenye Nezinhlobo
Okuqinile okuphezulu: I-sludge ithwala izinto eziqinile ezimisiwe neziguquguqukayo ezihlala phansi, zenze uqweqwe futhi zihlikihle, ngokungafani namanzi angcolile angahlanjululwanga.
Indawo yegesi ye-H2S: I-sludge engasebenzi ngomoya idala i-H2S eqoqeka futhi ijike ibe amanzi endaweni engaphezulu, okuyindawo embi kakhulu yokugqwala.
Ukuhlikihla: Isihlabathi, izinhlayiya nezinto eziqinile kuhlikihla izindawo ngesikhathi sokuxuba nokukhipha.
Ukugxila: Ama-salts, ama-sulphide nezinto eziphilayo zigxile kakhulu kunasemthonjeni wokufaka.
Izinhlelo zokusebenza nezimo zokusetshenziswa
Ukugaywa nokugcinwa kwe-sludge kamasipala, i-sludge yezimboni, ukwamukela indle, nanoma yikuphi ukugcinwa kwamanzi agxilile angenawo umoya-mpilo.
Ukucatshangelwa Kwezobuchwepheshe
Amathangi e-wastewater avame ukubhekana nokugeleza, umoya, uketshezi olunama-solids aphansi lapho indawo engaphansi komhlaba ibusa khona futhi i-coating ingafana. Amathangi e-sludge engeza indawo yegesi embi kanye nebhande lomugqa woketshezi lapho ukujikeleza komanzi/okomile kanye ne-H2S kugxila khona, kanye nama-solids ahlabayo. Impendulo yokuklama i-coating esezingeni eliphezulu ehlukaniswe ngezindawo (2C2F/3C3F endaweni yegesi), ukuphathwa kwegesi endaweni emboziwe, kanye nokuxuba nokukhipha okulinganiselwe ama-solids.
Ithangi elichazwe ngokuthi 'elinye nje ithangi le-wastewater' lizobona indawo yalo yegesi ihluleka kuqala, njengoba umgomo wokugqwala kwendawo yomhwamuko ubikezela.
Izinzuzo Nezinkinga
Izinzuzo:
Ukuqaphela i-sludge njengomsebenzi ohlukile, onzima kakhulu kukuvumela ukuthi uhlukanise isivikelo futhi wengeze ukuphathwa kwegesi lapho umsebenzi we-wastewater ubungeke uwudinge, ukuvimbela ukuhluleka kwangaphambi kwesikhathi.
Izinkinga:
Ukuhlelwa kwezindawo kanye nokuphathwa kwegesi kunezela umzamo wokucacisa kanye nezindleko uma kuqhathaniswa nomklamo ofanayo wamanzi angcolile; umsebenzi kufanele uchazwe ngokweqiniso, 'udaka' olungamakwe kabi empeleni luhlanjululwe lushintsha impendulo.
Umhlahlandlela Wokuqhathanisa Nokukhetha
Isici | Amanzi angcolile | I-sludge |
Izinto eziqinile | Phansi, kuyageleza | Phezulu, kuyahlala futhi kuyahlikihla |
Indawo yegesi i-H2S | Okuncane (kunomoya) | Kubi kakhulu (akunamoya-mpilo) |
Ukuhlikihla | Phansi | Phezulu (isihlabathi/izinto eziqinile) |
Ukumboza | Kuyafana | Izindawo ezisezingeni eliphezulu |
Ukuphatha igesi | Ngokuvamile akukho | Kudingeka indawo yokukhipha/ukubamba |
Izinqubo ezingcono kakhulu nokuthi ungalikhetha kanjani
Chaza umsebenzi ngokweqiniso: uma ugxilile, ungenawo umoya-mpilo futhi une-sulphide, hlukanisa indawo yokumboza (izinga eliphezulu endaweni yegesi kanye nomugqa woketshezi), engeza ukuphathwa kwegesi emathangini amboziwe, futhi usebenzise ukuxuba nokukhipha okulinganiselwe izinto eziqinile. Ungaphindi usebenzise incazelo efanayo yamanzi angcolile.
Indle (sludge) iwumsebenzi onzima ukwedlula amanzi angcolile ngenxa yezinto eziqinile eziphezulu, indawo yegesi ye-H2S embi kanye nokuguga. Yiphatha ngezingubo eziphezulu ezihlukanisiwe kanye nokuphathwa kwegesi ngamabomu, hhayi umklamo ofanayo wamanzi angcolile.
Imibuzo Evame Ukubuzwa (FAQ)
Kungani indle (sludge) igqwala kakhulu kunamanzi angcolile?
Indle (sludge) igxilile futhi ayinayo umoya-mpilo, ikhiqiza i-H2S eqoqeka futhi ijike ibe amanzi endaweni yekhanda, okuyindawo embi kakhulu yokugqwala, kuyilapho amanzi angcolile evamise ukugeleza, abe nomoya-mpilo futhi abe mncane.
Ingabe indle (sludge) iguga ithangi?
Yebo. Izinhlayiya eziqinile kanye nezinto ezinganyakazi zihlikihla izindawo ngesikhathi sokuxuba nokukhipha, zigqize imbozo ngokushesha kunamanzi angcolile angahlanjululwanga. Ukuxuba okukalwa ngezinto eziqinile kanye nokukhethwa kwamaphampu kubalulekile.
Ngingasebenzisa isicaciso sethangi lamanzi angcolile emdaka?
Akuphephile. Umdaka udinga imbozo esezingeni eliphezulu ehlukaniswe ngezindawo endaweni yegesi kanye nomugqa wamanzi, kanye nokuphathwa kwegesi emathangini amboziwe, okungekho kukho okunikezwa isicaciso samanzi angcolile afanayo.
Ukugqwala kwethangi lomdaka kuqala kuphi?
Esikhaleni somhwamuko kanye nasemugqeni wamanzi, lapho i-H2S ne-asidi kujiya khona futhi ukujikeleza kwamanzi nokoma kugxilisa ukugqwala, hhayi ngokufanayo ngaphansi kwamanzi.
Ingabe indawo yekhanda ihlala iyingozi?
Uma umdaka ungenawo umoya (anaerobic) ukhiqiza i-H2S, igesi enobuthi nengozi yokuqhuma, ngakho amathangi omdaka amboziwe adinga ukungeniswa komoya, ukuvikelwa komlilo kanye nokuhlukaniswa kwezindawo eziyingozi.
