Ukuphumelela kwezinga lokushisa eliphansi kanye nokwelashwa kwamanzi okuxubekile okuphansi: ukusetshenziswa kobunjiniyela be-polymer iron sulfate turbidity remove performance

Lizinga lokushisa eliphansi lamanzi ane-turbidity ephansi (izinga lokushisa elingu-Ukwelapha Amanzingenxa yokuzinza kwayo okuphezulu kwe-colloid nokusebenza kahle kwe-flocculation ephansi. Ngokuguquguquka kwayo okuhlukile kwe-ferric sulfate nokuvumelana nobunjiniyela, i-polyric sulfate (PFS) izuze ukusebenza ngempumelelo kulo mkhakha eminyakeni yamuva nje futhi ibe obunye bobuchwepheshe obuyisisekelo bokuthuthukisa izinga lekhwalithi yamanzi.

1. Ubunzima ekushiseni okuphansi kanye nokwelashwa kwamanzi ane-turbidity ephansi kanye nezinzuzo zobuchwepheshe be-PFS

1. Izinga lokushisa eliphansi kanye nenselelo ephansi yokwelashwa kwamanzi anemfucumfucu ephansi

Umkhawulo wokushisa ophansi: ukwehla kwezinga lokushisa kwamanzi kuholela ekwehleni kwamandla e-kinetic yamangqamuzana, izinga le-hydrolysis ye-coagulant liyancipha cishe izikhathi ezingu-2-4, ama-flocs akhiwe akhululekile futhi abuthakathaka, futhi umjikelezo wokuxazulula unwetshwa ngo-30% -50%.

Isici se-turbidity ephansi: ukugxila okuphansi kwezinto ezimisiwe (

2. Izinzuzo eziyinhloko zobuchwepheshe ze-PFS

Izici ze-hydrolysis esheshayo: I-PFS isengakhishwa nge-hydrolyzed ngokushesha ezingeni lokushisa eliphansi ukuze ikhiqize i-multinucleated hydroxyl complex (efana ne-[Fe_3 (OH) _4] ^ {5 +}), eyenza ngokushesha ingabi namandla inkokhiso ye-colloidal surface ngokusebenzisa ukuminyana kokushaja okuphezulu okuhle (ngaphezulu kuka-+30 mV).

Ukuqinisa ibhuloho le-adsorption: ukwakheka kweketango le-polymer kungawela umgoqo wamandla endaweni yokushisa ephansi, kukhangise ngokuqondile izinhlayiya ezinhle ukuze zakhe imbali ye-alum ecinene (usayizi wezinhlayiyana> 1 mm), futhi izinga lokuhlala likhuphuka ngo-40% -60% uma liqhathaniswa nama-agent wendabuko.

I-Synergy of oxidation: i-iron trivalent iron (Fe³) isenga-oxidize enye into ephilayo encibilikayo (njenge-humic acid) ezingeni lokushisa eliphansi, elingasuswa ngokugeleza, kanye nezinga lokususwa kwe-turbidity likhuphuka ngo-15% -20%.

2. Izimo ezisemqoka kanye namacala okusebenza kobunjiniyela

1. UmasipalaUkuphuza Ukwelapha Amanzi

Isitshalo samanzi asenyakatho (izinga lokushisa lamanzi aluhlaza 4℃, i-turbidity 15 NTU) esetshenziswa i-PFS esikhundleni se-polyaluminium chloride (PAC), inani elingeziwe lehla lisuka ku-50 mg/L laya ku-30 ​​mg/L, isikhathi sokukhokha sama-catkins sancishiswa ukusuka kumaminithi angu-45 kuya kumaminithi angu-25, futhi ukuguquguquka kwamanzi kwefektri kwaba ngaphansi kwe-NTU ye-50.

2. Uhlelo lwamanzi ajikelezayo ezimbonini

Ukuphrinta nokudaya kabusha ukusetshenziswa kwamanzi angcolile: ngaphansi kwezimo zokusebenza ezingu-10℃, i-PFS kanye ne-anionic polyacrylamide (AP AM) ukusetshenziswa kabusha, izinga lokususwa kwemfucumfucu likhuphuka lisuka ku-78% liye ku-95%, futhi ukukhiqizwa kodaka kwehliswa ngo-20%.

Ukulungiswa kwamanzi e-ultrapure embonini ye-elekthronikhi: izinhlayiya ze-silicon ye-nanoscale (usayizi wezinhlayiyana

3. Isu lokuthuthukisa ubunjiniyela kanye nokuqamba okusha kwezobuchwepheshe

1. Ukufakwa kwe-Dynamic nokulawula ubuchwepheshe bokwengeza

Ngokusekelwe ohlelweni lokuqapha lwe-inthanethi lwe-turbidity / izinga lokushisa, ukulungiswa okuguquguqukayo komthamo we-PFS (10-80 mg/L) kutholwa ukuze kugwenywe ukuphindaphinda kwe-turbidity kanye nezinsalela ze-iron ion ezibangelwa ukwengezwa ngokweqile.

Icala: Isikhungo sokuhlanza indle samukele i-algorithm yokulawula ye-PID engacacile, izindleko ze-ejenti zehliswa ngo-18%, futhi ukugcwala kwe-ferric yama-ion ensimbi kumfucumfucu bezinzile

2. Inhlanganisela kanye nenqubo yokwandisa ukusebenza kahle

Inhlanganisela ye-PFS + PAM: ngemva kokungathathi hlangothi kukagesi kwe-PFS, engeza amandla e-flocs angu-0.1-0.5 mg/L APAM athuthukisiwe, afanele ikhwalithi yamanzi axubile aphansi kakhulu ane-turbidity

Ukuthuthukiswa kwe-pre-oxidation: i-potassium permanganate ehlanganisiwe (0.2-0.5 mg/L) pre-oxidation, uqhekeke ungqimba oluvikelayo lwe-colloid lwento ephilayo ekushiseni okuphansi, kanye nomthamo we-PFS uphinde wehliswe ngo-25%.

3. Ukuzivumelanisa nezisetshenziswa kanye nokuthuthukiswa kokuvumelana nezimo

Ukuthuthukisa i-Tubular mixer: ngokwandisa inani le-G (> 500s ¹), isikhathi sokuhlanganisa sifinyezwa sibe amasekhondi angu-10, futhi isivuno se-alum peanut sikhuphuka ngo-30%.

Inqubo yokuhlanganisa i-gas flotation-precipitation: iyunithi ye-air flotation encibilikisiwe yengezwa ekugcineni kwethangi le-sedimentation, futhi i-microflocs (0.2-0.5 mm) eyakhiwe yi-PFS inothiswa kabili, futhi izinga lokususwa kwe-turbidity lenyuka ngo-8% -12%.

4. Umnotho wezobuchwepheshe kanye nezinzuzo zemvelo

Ukuqhathaniswa kwezindleko zokusebenza: Izindleko zokuhlanza amanzi amathani e-PFS zehliswa ngo-0.05-0.12 yuan ngaphansi kwe-PAC, i-sludge yehla ngo-15% -30%, futhi izinga lokugqwala kwemishini liyancipha ngaphezu kuka-50%.

Inzuzo yokusimama: Azikho izici zezinsalela ze-aluminium ion eziyenza ihlangabezane nezinga le-GB 5749-2022 lamanzi okuphuza ukuze kugwenywe ingozi ye-neurotoxicity kasawoti we-aluminium wendabuko.

5. Isiqondiso sentuthuko yesikhathi esizayo

Ukuthuthukiswa kwesistimu yokudosa ehlakaniphile: bikezela ukuguquguquka kwekhwalithi yamanzi okuhlanganiswe nemodeli yokufunda yomshini, futhi uthole ukulawulwa okuzenzakalelayo nokunembile komjovo we-PFS.

Ucwaningo nokuthuthukiswa kwama-ejenti ahlanganisiwe: ukuthuthukisa ukulungiswa okuyinhlanganisela ye-PFS ngama-enzyme e-biological kanye nama-nanomaterials ukuze kuthuthukiswe amandla okubamba ama-nanocolluids aphansi lokushisa (

Ngokusungula ubuchwepheshe obusha bobunjiniyela, i-polymer iron sulfate ikhuthaza ukukhuphuka kwezinga lokushisa eliphansi kanye nokwelashwa kwamanzi okuxubekile okuphansi ukusuka "ebunzimeni obujwayelekile" kuya "kumnotho osebenzayo", ukuhlinzeka ngosekelo olubalulekile lobuchwepheshe lokuphepha kwamanzi kanye nokonga amanzi ezimbonini ezindaweni eziphakeme nezibandayo.
