Esimweni sanamuhla, izinkinga zendle ezibangelwa ukuthuthukiswa kwezimboni ziye zaphathwa kahle ekhaya nakwamanye amazwe. Uma sikhuluma ngalokhu, kufanele sikhulume ngesimo sokususa umbala we-flocculant ekuhlanzweni kwamanzi. Ngokuyisisekelo, indle ekhiqizwa yizimboni eziningi idinga ukusebenzisa i-flocculant esusa umbala. I-Yixing Cleanwater izokwethula ulwazi olufanele kanye nezicelo emikhakheni ehlukene.
Ama-flocculant ahlukahlukene asusa umbala e-polymer asetshenziswa kabanzi emkhakheni wokwelashwa kwamanzi nendle yezimboni kwamanye amazwe, phakathi kwawo i-polyacrylamide (PAM) iwuhlobo oluyinhloko lwe-flocculant esusa umbala. Uma kuqhathaniswa nama-flocculant kasawoti angaphili, i-PAM, njengohlobo olusha lwe-ejenti yokwelapha amanzi, inezinzuzo eziningi: kulula futhi kulula ukuyisebenzisa, umphumela we-flocculation uphakeme kaningi kune-flocculant kasawoti angaphili; isivinini sokugeleza okusheshayo kanye nokuthungwa kwendle, ukusebenza kahle kokukhipha amanzi odakeni; umphumela wokwelapha okhethekile emanzini athile angcolile; imishini elula edingekayo, indawo encane; izindleko zokwelashwa eziphansi; indle ingaphinde isetshenziswe futhi isetshenziswe kabusha, njll.
Ukusetshenziswa kweI-flocculant ye-PAM esusa umbala emikhakheni ehlukene yohlelo lokusebenza:
1. Ukusetshenziswa embonini yokwenza amaphepha
Ukusebenzisa i-PAM enesisindo esikhulu sama-molecule njenge-flocculant esusa umbala kungandisa izinga lokuna kwe-pigment nezinye izinto emanzini amhlophe futhi kunciphise ukulahleka kwazo. Ukwengeza i-PAM engu-0.25 ~ 0.5% ku-pulp kungandisa izinga lokusaphazeka kwe-pulp ngezikhathi ezingu-40 ~ 80, kunciphise okuqukethwe okuqinile emanzini amhlophe cishe ngo-66%, kwandise okuqukethwe komlotha ephepheni, kwandise izinga lokugcina le-pigment njengobumba olumhlophe ngo-8 ~ 18%, futhi konge u-20kg we-pulp ngethani lephepha. Ngaphezu kwalokho, ngemva kokusebenzisa i-PAM, ukungcoliswa kwamanzi amhlophe kuncishiswa kakhulu, kunciphisa ukungcola kwemvelo. Isibonelo, izinto eziqinile ezimisiwe zamanzi amdaka e-pulp amhlophe anobisi ane-pH = 6.8 zingama-3000ppm. Ngemva kokwelashwa nge-PAM ngezinga le-hydrolysis elingu-5 ~ 10%, isisindo se-molecule esingu-5.5 ~ 10 million, kanye ne-500ppm ye-aluminium sulfate, amanzi amhlophe angaguqulwa abe uketshezi olungenambala nolusobala, kanti izinto eziqinile ezimisiwe zincishiswa zibe ngaphansi kuka-50ppm.
2. Ukusetshenziswa kwama-flocculant asusa umbala ekuhlanzweni kwamanzi
①Ukulwa nokukhula nokunciphisa izinga
Ekuhlanzweni kwamanzi nendle yezimboni, amanzi angaphekiwe kumele aqale acaciswe. Ama-flocculant e-PAM asusa umbala kanye nama-coagulant angaphili avame ukusetshenziswa ngokuhlanganiswa, okunganciphisa kakhulu ukusetshenziswa kwama-coagulant angaphili, kugweme ukuvaleka kwemishini kanye nokugqwala ngenxa yokusetshenziswa ngokweqile kwama-coagulant angaphili, futhi kuvimbele ukwakheka kwesikali. Izingxenye ezingu-37.5 ze-PAM ezinesisindo sama-molecule esingaphansi kwesigidi esingu-1 kanye nezingxenye ezingu-50 ze-sodium tripolyphosphate zisetshenziselwa ukwakha i-scale inhibitor, okungavimbela ngokuyisisekelo isikali sama-heat exchanger alinganiswe kakhulu.
②Ukwelashwa kwendle yezimboni
3. Ukusetshenziswa kwe-flocculants yokususa umbala ekuphathweni kwamanzi amdaka embonini kashukela
Ijusi likamoba elikhishwa emshinini wokunyathelisa yizimboni zikashukela livame ukuba mdaka futhi ukwakheka kwalo nakho kuyinkimbinkimbi kakhulu. Ukuze kutholakale ijusi likamoba elihlanzekile, kudingeka kufakwe izihlungi zamakhemikhali. Esikhathini esidlule, ama-flocculant angabonakali ayevame ukusetshenziswa, kodwa ngokuthuthuka kwemboni kashukela, ama-flocculant angabonakali awasakwazi ukuhlangabezana nezidingo zokukhiqiza. Eminyakeni yamuva nje, ukusetshenziswa kwe-PAM embonini kashukela kungakhuphula izinga lokuchitheka kwenhlabathi ngokuphindwe ka-20.
Ngamafuphi, uma sikhetha i-polyacrylamide PAM decolorization flocculant ngokwesimo sangempela, kufanele siyikhethe ngokwezimo nezimo zokusetshenziswa ezahlukene. Ngakho-ke, ukukhethwa kwe-polyacrylamide nakho kubaluleke kakhulu.
Uma udinga imikhiqizo yethu, sicela ukhululekeXhumana nathi!
