I-coagulant yokwelapha indle kanye ne-flocculant zinomphumela omuhle uma zisetshenziswa ndawonye

In I-Coagulant (I-Polyaluminum Chloride, eyaziwa kakhulu ngokuthi i-ejenti yokuhlanza amanzi, eyaziwa nangokuthi i-polyaluminum chloride, i-polyaluminum ngamafuphi,I-PAC) kanyeI-Flocculant (i-polyacrylamide, okungeyama-polymer amaningi anama-molecule,I-PAM) Ngaphansi kwesenzo, into elengayo idlula ekunyakazeni ngokomzimba kanye nasekunyakazeni kwamakhemikhali, ngaleyo ndlela yakhe ama-floc amakhulu ento elengayo. Ngaphansi kokuntanta kweqembu lama-bubble, “ama-floccule” ayantanta aye endaweni ewuketshezi ukuze akhe i-scum, ehlukaniswa namanzi ngokusebenzisa i-slag scraper. Ukuhlanza umlomo ngeke kubangele ukuvaleka, futhi ukusetshenziswa kwe-coagulant kanye ne-flocculant ekuhlanzweni kwendle kuyasebenza.

I-Coagulant (i-polyaluminum chloride, eyaziwa nangokuthi i-water purifier, eyaziwa nangokuthi i-polyaluminum chloride, ebizwa nangokuthi i-polyaluminum, i-PAC) isetshenziswa kakhulu ekuhlanzeni amanzi okuphuza namanzi angcolile ezimbonini, kanye nokwelashwa kwekhwalithi yamanzi ekhethekile (njengendle enamafutha, ukuphrinta nokudaya indle yokwenza amaphepha, indle yokuncibilikisa, equkethe izakhiwo zemisebe, izinsimbi ezisindayo ezinobuthi njenge-Pb, Cr kanye nendle equkethe i-F, njll.), ngaphezu kwalokho, isetshenziswa kabanzi ekubunjweni okunembile, ukubhoboza uwoyela, isikhumba, iphepha lensimbi, njll., i-coagulant isetshenziswa emanzini Ngesikhathi senqubo yokwelapha, izinhlayiya ze-colloidal emanzini zingahlanganiswa futhi zihlanganiswe ndawonye. Ngokuvamile, inqubo yokuhlanganisa amanzi iwukufaka amakhemikhali ngesikhathi senqubo yokwelapha amanzi ukuze kubangele ukungcola ukuthi kuhlangane, kushintshe umbala, kususe izinto eziqinile ezilengisiwe, kususe ukungcola namagciwane.

I-Polyaluminum ferric chloride inomphumela omuhle wokujiya. I-Polyaluminum ferric chloride (PAFC) uhlobo olusha lwe-flocculant ye-cationic composite esebenza kahle kakhulu. Inezinzuzo zobuso obubanzi, umphumela omuhle wokususa ukungcola, kanye nokugqwala okuncane kumapayipi emishini; futhi inezici zokuxazulula ukujiya kwe-flocculant yensimbi ngokushesha, ukuhlukaniswa okulula, ukusebenza okuhle ekuphathweni kwamanzi okushisa okuphansi, kanye nobubanzi benani le-PH ekuphathweni kwamanzi. Njengamanje, i-polyaluminum ferric chloride isetshenziswe ngempumelelo ekwelapheni amanzi okuphuza, amanzi ezimboni kanye namanzi angcolile ahlukahlukene ezimboni.

I-Coagulant (i-polyaluminum chloride, eyaziwa kakhulu ngokuthi i-ejenti yokuhlanza amanzi, eyaziwa nangokuthi i-polyaluminum chloride, ebizwa nangokuthi i-polyaluminum, i-PAC) inamandla okususa umbala nokususa ukungcola, kanti umphumela wokuhlanza amanzi uphindwe ka-4-6 kunowe-AL2(SO4)3. Iphindwe ka-3-5 inani le-ALCL3, umthamo mncane, umphumela mkhulu, izindleko ziphansi, inzuzo iphezulu, ukuzivumelanisa nobubanzi benani le-pH, ukwehla kwenani le-pH lamanzi aluhlaza kuncane, ngakho-ke ayinawo umphumela wokugqwala emishinini yamapayipi, asikho isidingo sokwengeza ezinye izithasiselo, futhi ama-floc akha ngokushesha Kodwa-ke, ijiyile, inomsebenzi ophezulu, ukucwila okuphezulu, kanye nemvula esheshayo, ngakho-ke umphumela wokuhlanza emanzini anomswakama ophezulu usobala kakhulu.
