Kufanele aphathwe kanjani amanzi angcolile asensimini kawoyela?
Njengoba isidingo sikawoyela ezweni lami silokhu sikhula, izinkampani zikawoyela zinaka kakhulu ubuchwepheshe bokumba uwoyela, nokuxhashazwa kwezizinda zikawoyela kuyanda.Nokho, amanzi amaningi angcolile azokhiqizwa ngesikhathi sokumbiwa kwezizinda zikawoyela, ikakhulukazi ezimayini ezinkulu zikawoyela.Okuqukethwe kwamanzi oketshezini olukhiqiziwe kuphezulu uma kuqhathaniswa.Ukuchithwa okuqondile kwamanzi angcolile asuka ezimayini zikawoyela ngeke nje kubangele umonakalo omkhulu emvelweni, kodwa futhi kungcolisa amanzi angaphezulu nezolimo., okuholela ekufeni kwezilwane nezitshalo kanye nezifo ezingase zibe khona kubantu, okubangela ukulimala okukhulu ezimpilweni zabantu bendawo. .Ngaphezu kwalokho, amagesi ane-asidi noma usawoti emanzini angcolile kawoyela azosheshisa ukugqwala kwemishini yamapayipi;okuqinile okumisiwe emanzini angcolile kawoyela kuzovimba ukwakheka;amagciwane ezimboni emanzini angcolile kawoyela azogqwala amapayipi, avimbe amapayipi, futhi adale umonakalo wamanzi.Ukuwohloka kwekhwalithi.Njengoba sibhekene nesimo samanzi angcolile asensimini kawoyela, singasebenzisa indlela yokuhwamuka kwezinga lokushisa eliphansi ukuze sihlanze amanzi angcolile.
Iyini i-oilfield wastewater
Ngokwemiphumela efanele yokuhlaziya, izingxenye eziyinhloko emanzini angcolile anamafutha zihlanganisa uwoyela ongahluziwe osindayo, izinto ezinamafutha acid, izinto zokuqeda amandla, izinto ze-mercaptan, izinto ze-colloid, ama-sulfide, ama-carbonates, ama-sulfate, njll. Ngenxa yokuthi i-organic matter ne-inorganic matter esele emanzini ine ukwakheka okuyinkimbinkimbi, kuletha izinga elithile lobunzima ekwelapheni kwamanzi angcolile kawoyela.Amanzi angcolile anamafutha anomthamo omkhulu kawoyela, futhi isimo sokwakheka nokuba khona kwezinto ezingcolisa uwoyela emanzini nazo zihlukile.Cishe kunezinhlobo ezinhlanu zamafutha ezikhona emanzini angcolile anamafutha:
(1) Izinga eliphezulu lokugaywa kwamaminerali lisheshisa izinga lokugqwala futhi lenza ukucocwa kwamanzi angcolile kube nzima;
(2) Okuqukethwe kukawoyela kuphakeme, kukhulu kakhulu kunezindinganiso zekhwalithi yamanzi ezidingwa izitolo ezihlukahlukene;
(3) Iqukethe inani elikhulu lamagciwane, futhi ukwanda okukhulu kwamagciwane ngeke nje kucekele phansi amapayipi kodwa futhi kubangele ukuvaleka okukhulu kokwakheka kwawo;
(4) Iqukethe inani elikhulu lama-ion enza isikali, futhi amanzi akhiqiziwe aqukethe i-SO42-, CO32-, Ca2+, Mg2+, Ba2+ namanye ama-ion alula ukukala;
(5) Okuqukethwe kwezinto eziqinile ezimisiwe (i-polymer endaweni yomjovo) iphakeme futhi izinhlayiya zincane, ezingabangela kalula ukuvinjelwa kokwakheka.
Indlela yokuhwamuka kwezinga lokushisa eliphansi lamanzi angcolile ase-oilfield
Indlela yokuhwamuka kwezinga lokushisa eliphansi yamanzi angcolile asezindaweni zikawoyela iyindlela yokulahlwa ngokomzimba esetshenziswa kakhulu ukwelapha amanzi angcolile asendaweni kawoyela kanye namanzi angcolile anamafutha.Ngaphansi kwesenzo sesistimu ye-vacuum ku-evaporator yezinga lokushisa eliphansi, idigri ye-vacuum ku-vacuum evaporation degree iyakhuphuka.Amanzi angcolile amuncwa okokusebenza ngevalvu yokufaka amanzi aluhlaza ngosizo lwevacuum ku-evaporator.Lapho amanzi angcolile efika ezingeni likaketshezi elimaphakathi ethangini lokuhwamuka, ukuphakela uketshezi kuyama.Ngemuva kokuthi i-vacuum degree ifinyelele inani elibekiwe, umusi wangaphandle usetshenziselwa ukushisa.Izingxenye zamaphuzu aphansi abilayo ziyahwamuka.Izingxenye ezibilisa kakhulu zamanzi angcolile zihlala ku-evaporator ngendlela yokugxila.I-concentrate ikhishwa ngokuzenzakalelayo ngocingo.Isitimu singena endaweni epholile eduze kwepayipi, ukushintshana nesistimu ye-condensation yangaphandle ibe uketshezi, futhi amanzi acwecwe akhishwe eduze kwepayipi lokuphuma.
Umdwebo wohlelo lwe-evaporator yokushisa okuphansi
Ikristali yokuhwamuka kwezinga lokushisa eliphansi, impumelelo yobuchwepheshe enelungelo lobunikazi ye-Kunshan WSD Environmental Protection Equipment Co., Ltd., isetshenziswe kabanzi emkhakheni wamanzi angcolile ezimayini zikawoyela, ithola imiphumela emihle impela yokwelapha futhi izuza ukunconywa kubasebenzisi abaningi.Inqubo ye-WSD yokuhwamuka kwezinga lokushisa eliphansi kanye ne-crystallization ingasiza amanzi angcolile ase-oilfield afinyelele ukukhishwa kweqanda, ukuxazulula ngokuphelele amaphuzu obuhlungu wokuqukethwe okuphezulu kawoyela kanye nokulahlwa kwamanzi angcolile aphezulu e-COD ekupheleni kwamanzi angcolile ase-oilfield.
Izinzuzo zenqubo ye-WSD yezinga lokushisa eliphansi lecrystallization evumelana nemvelo
Ikristalu enezinga lokushisa eliphansi lehlisa umthamo wotshwala kamama ngaphezu kuka-80%, yehlisa kakhulu izindleko zenkampani zokulahla imfucuza eyingozi futhi ivule lonke uchungechunge lwezinqubo.
Isimo sokusebenza sokuhwamuka kwezinga lokushisa eliphansi singathuthukisa kakhulu umphumela wamanzi wokuhwamuka.Izinga lokususwa kwe-COD lamanzi akhiqiziwe liphezulu ngaphezu kwama-95%, futhi amanzi ajiyile angemuva angena ohlelweni lwe-biochemical ukuze alashwe.
I-crystallizer ye-evaporation esezingeni eliphansi inesakhiwo sayo esikhethekile futhi ayijwayele ukuvala, ukupheka kanye nokukala lapho isebenza ne-COD ephezulu kanye namanzi angcolile anosawoti omningi.
Imishini ngokwayo ihlanganisiwe, ihlakaniphile, futhi iklanywe ngezimiso ezilula zenqubo.Akudingi izisebenzi ezikhethekile zokusebenza nokuhlola, okunciphisa kakhulu izindleko zabasebenzi.
