I-coagulant yokwelapha indle kanye ne-flocculant inomphumela omuhle uma isetshenziswa ndawonye

In I-coagulant (I-Polyaluminium Chloride, eyaziwa ngokuthi i-ejenti yokuhlanza amanzi, eyaziwa nangokuthi i-polyaluminium chloride, i-polyaluminium ngamafuphi,I-PAC) kanyeI-Flocculant (i-polyacrylamide, okuyingxenye ye-polymer ephezulu yamangqamuzana,PAM) Ngaphansi kwesenzo, udaba olumisiwe luba ne-flocculation ebonakalayo kanye ne-chemical flocculation, ngaleyo ndlela yakhe ama-subject flocs amakhulu amisiwe.Ngaphansi kwe-buoyancy yeqembu lamabhamuza, "ama-floccules" antanta endaweni ewuketshezi ukuze akhe udoti, ohlukaniswa emanzini kusetshenziswa i-slag scraper.Ukuhlanza i-nozzle ngeke kubangele ukuvala, futhi ukusetshenziswa kwe-coagulant ne-flocculant ekwelapheni indle kusebenza kahle.

I-coagulant (i-polyaluminium chloride, eyaziwa ngokuthi i-water purifier, eyaziwa nangokuthi i-polyaluminium chloride, ebizwa ngokuthi i-polyaluminium, i-PAC) isetshenziselwa ikakhulukazi ukuhlanzwa kwamanzi okuphuza kanye namanzi angcolile ezimbonini, kanye nokwelashwa kwekhwalithi yamanzi ekhethekile (njengendle enamafutha, Ukuphrinta nokudaya indle yokwenza iphepha, indle encibilikayo, equkethe izinto ezikhipha imisebe, izinsimbi ezinobuthi ezinobuthi njenge-Pb, Cr kanye nendle equkethe u-F, njll.), ngaphezu kwalokho, ibuye isetshenziswe kabanzi ekubunjweni okunembayo, ukumba uwoyela, isikhumba, ukwenza amaphepha okusansimbi, njll., i-coagulant isetshenziswa emanzini Ngesikhathi senqubo yokwelapha, izinhlayiya ze-colloidal emanzini zingahlanganiswa futhi zihlanganiswe ndawonye.Ngokuvamile, inqubo yokuhlanganisa iwukwengeza amakhemikhali phakathi nenqubo yokwelapha amanzi ukuze kubangele ukungcola kugoqene, kushintshe umbala, kususe okuqinile okumisiwe, kususe i-turbidity kanye namagciwane.

I-Polyaluminium ferric chloride inomphumela omuhle we-coagulation.I-Polyaluminium ferric chloride (PAFC) iwuhlobo olusha lwe-inorganic cationic composite flocculant esebenza kahle kakhulu.Inezinzuzo zendawo ebanzi, umphumela omuhle wokususwa kwe-turbidity, kanye nokugqwala okuncane kumapayipi wemishini;ibuye ibe nezici ze-iron fast iron flocculant flocculation settlement, ukuhlukaniswa okulula, ukusebenza kahle ekwelashweni kwamanzi okushisa okuphansi, kanye nohlu olubanzi lwenani le-PH ekwelapheni kwamanzi.Njengamanje, i-polyaluminium ferric chloride isetshenziswe ngempumelelo ekwelapheni amanzi okuphuza, amanzi ezimboni kanye namanzi angcolile ahlukahlukene ezimbonini.

I-coagulant (i-polyaluminium chloride, evame ukubizwa ngokuthi i-ejenti yokuhlanza amanzi, eyaziwa nangokuthi i-polyaluminium chloride, ebizwa ngokuthi i-polyaluminium, i-PAC) inamandla okuqeda umbala nokuqeda ukungcola, futhi umphumela wokuhlanza amanzi izikhathi ezingu-4-6 kune-AL2(SO4)3.Izikhathi ezi-3-5 inani le-ALCL3, umthamo mncane, umphumela mkhulu, izindleko ziphansi, inzuzo iphezulu, ukuguquguquka kwenani elibanzi le-pH, ukuncipha kwenani le-pH lamanzi aluhlaza kuncane. , ngakho-ke ayinawo umthelela wokugqwala emishinini yamapayipi, asikho isidingo sokwengeza ezinye izithasiselo, futhi ama-flocs akheka ngokushesha Nokho, iwugqinsi, inomsebenzi omningi, ikwazi ukucwila kakhulu, kanye nemvula esheshayo, ngakho-ke umphumela wokuhlanza emanzini anemfucumfucu ephezulu ikakhulukazi. sobala.
