Ucwaningo mayelana nokuguquguquka kwe-polymeric ferric sulfate ekwelapheni izinga lokushisa eliphansi kanye namanzi angcolile ane-turbidity ephansi
2025-03-03
Izinga lokushisa eliphansi kanye ne-turbidity ephansiUkwelapha Amanzi Angcolileingenye yezinkinga zezobuchwepheshe emkhakheni wokuhlanza amanzi. Izinga lokushisa eliphansi (ngokuvamile elingaphansi kuka-20 ℃) lizonciphisa izinga lokusabela kwamakhemikhali futhi linciphise ukusebenza kahle kwe-hydrolysis yama-coagulants; I-turbidity ephansi ibangelwa inani elincane lezinhlayiya ezimisiwe kanye nokuzinza okuphezulu kwe-colloidal, okwenza kube nzima ukwenza ama-flocs.I-Polyferric sulfate (PFS), njenge-inorganic polymer coagulant, ibonise izinzuzo ezibalulekile ekuphathweni kwamanzi angcolile asezingeni eliphansi kanye ne-turbidity ephansi eminyakeni yamuva ngenxa yezakhiwo zayo eziyingqayizivele ze-physicochemical. Lesi sihloko sihlanganisa idatha yokuhlola kanye nezimo zohlelo lokusebenza ukuhlola ukuguquguquka kwayo kanye nendlela yokwenza.
Izinselelo Ekwelapheni Izinga Lokushisa Eliphansi kanye Namanzi Angcolile Anesibhuqu Esiphansi
1. Izinga lokushisa eliphansi imI-Pact:
Ngaphansi kwezimo zokushisa eziphansi, ukunyakaza kwama-molecule e-Brownian kuba buthaka, amandla okukhangisa ezinhlayiya ze-colloidal ayancipha, izinga le-hydrolysis lama-coagulants liyancipha, okuholela ekwakhekeni kwe-floc kancane futhi okuxekethile kanye nokunciphisa ukusebenza kahle kokuxazulula.
2. Izici ze-turbidity ephansi:
Ukuhlangana kwezinto eziqinile ezimisiwe emanzini ane-turbidity ephansi iphansi, futhi ukushaja okungaphezulu kwezinhlayiya ze-colloidal kuzinzile. Ama-coagulant endabuko anzima ukuwohloka ngempumelelo ngokusebenzisa i-electrostatic neutralization futhi adinga ikhono eliqinile le-adsorption bridging.
Izakhiwo zomzimba namakhemikhali kanye nezinzuzo ze-polymeric ferric sulfate
1. Indawo ebanzi yokuguquguquka kwe-pH:
I-Polymeric ferric sulfate ingasebenza ngempumelelo phakathi kwebanga le-pH elingu-411, ilungele ikakhulukazi amanzi aluhlaza anezinga lokushisa eliphansi kanye ne-turbidity ephansi (i-pH 69 iyibanga elifanele), ibe nomthelela omncane ku-alkalinity yamanzi aluhlaza futhi inciphise ubungozi bokugqwala kwemishini.
2. Ikhono elisebenzayo lokuhlanganisa:
Umkhiqizo wayo we-hydrolysis uyinkimbinkimbi enama-multi-core, eshesha ukuwohloka kwezinhlayiya ze-colloidal ngokusebenzisa izindlela ezinjengokungathathi hlangothi kukagesi kanye ne-adsorption bridging, yakhe izimbali eziminyene ze-alum ezinejubane lokuxazulula ngokushesha, okuthuthukisa kakhulu ukusebenza kahle kokuhlukaniswa koketshezi oluqinile ezindaweni ezisezingeni eliphansi.
3. Indlela yokuguquguquka kwezinga lokushisa eliphansi:
Izici zokuncibilika kanye ne-hydrolysis: Uma izinga lokushisa lehla laya ku-2 ℃, izinga le-hydrolysis le-polymeric ferric sulfate lehla kakhulu, kodwa uma liqhathaniswa namanye ama-coagulant ensimbi noma e-aluminium kasawoti, imikhiqizo yayo ye-hydrolysis isengakwazi ukugcina umsebenzi ophezulu. Ngokulungisa umthamo (ngokuvamile ukhuphuka ngo-10% noma ngo-20%), umphumela wezinga lokushisa eliphansi unganxeshezelwa ngokwengxenye.
Ukuzinza kwesakhiwo se-floc: Ama-floc akhiqiziwe aminyene futhi anokumelana okuqinile kwe-shear, futhi angagcina ukusebenza kahle kokuxazulula ngisho nasezingeni eliphansi lokushisa.
Ukuhlaziywa Komphumela Wokuhlola Nokusebenzisa
1. Umphumela we-coagulation ngaphansi kwezimo zokushisa eziphansi:
Ukuhlola kubonise ukuthi uma izinga lokushisa lamanzi lingaphansi kuka-20 ℃, izinga lokususwa kwe-turbidity kanye ne-COD nge-polymeric ferric sulfate kusengafinyelela ngaphezu kwama-85%, kangcono kakhulu kunama-coagulant endabuko afana ne-polyaluminium chloride (PAC). Isibonelo, ebusika (emazingeni okushisa amanzi angama-25 ℃), indawo yokuhlanza indle esenyakatho isebenzisa i-polymeric ferric sulfate, enyuse izinga lokususwa kwe-COD ukusuka ku-70% kuya ku-90% futhi yanciphisa isikhathi sokumisa ama-flocs ngama-30%.
2. Izinzuzo zokwelapha amanzi aluhlaza ane-turbidity ephansi:
Emanzini aluhlaza ane-turbidity engaphansi kwe-10 NTU, i-polymeric ferric sulfate inganciphisa ukuthuthumela ibe ngaphansi kwe-1 NTU ngokuthuthukisa umphumela we-adsorption bridging, ofaneleka ngokukhethekile ukuhlanzwa kwamanzi angcoliswe kancane kanye nolwelwe oluqukethe amanzi angcolile.
Imikhawulo yohlelo lokusebenza nezinyathelo zokuthuthukisa
1. Imikhawulo:
Ukuncika emazingeni okushisa: Uma izinga lokushisa lamanzi lingaphansi kuka-2 ℃, kufanele kuthathwe izinyathelo zokuhlukanisa (njengokushisa kwangaphakathi noma ukushisisa amapayipi), ngaphandle kwalokho ukusabela kwe-hydrolysis kuzocishe kumile.
Ingozi yokugqwala kwezinto: Ama-ion e-iron agxile kakhulu angase abangele ukugqwala kwamapayipi ensimbi, adinge ukusetshenziswa kwezinto ezimelana nokugqwala noma ukwengezwa kwezivimbela ukugqwala.
2. Isiqondiso sokuthuthukisa:
Inhlanganisela yama-ejenti ahlanganisiwe: Uma ihlanganiswa ne-polyacrylamide (PAM), ingathuthukisa isakhiwo se-floc futhi inciphise umthamo emazingeni okushisa aphansi.
Ukulungiswa kwepharamitha yenqubo: Thola umthamo ophelele (ngokuvamile u-550 mg/L) kanye nomfutho onyakazayo ngokuhlolwa kwebhika ukuze ubhalansise izindleko nokusebenza kahle.
Isiphetho kanye neProspect
I-Polymeric ferric sulfate isiphenduke enye yezinto ezithandwayo zokwelapha amanzi angcolile anezinga lokushisa eliphansi kanye ne-turbidity ephansi ngenxa yokuguquguquka kwawo okubanzi kwe-pH, ikhono lokugeleza elisebenzayo, nokuzinza ezindaweni ezinezinga lokushisa eliphansi. Ucwaningo lwesikhathi esizayo lungaqhubeka luhlole ukusetshenziswa kwalo okuyinhlanganisela ngezinto ezintsha ezifana ne-diatomaceous earth eguquliwe, noma luthuthukise ukusebenza kahle kwe-hydrolysis esezingeni eliphansi ngokuthuthukisa izinqubo zokukhiqiza. Kubunjiniyela obusebenzayo, kuyadingeka ukuklama ngokwesayensi izikimu zokudosa ngokusekelwe ezicini zekhwalithi yamanzi nezimo zezulu ukuze kuzuzwe izinjongo zokwelashwa kwamanzi ezisebenza kahle, ezongayo neziqhubekayo.
