Esimeni sanamuhla, izinkinga zendle ezibangelwa ukuthuthukiswa kwezimboni ziye zaphathwa kahle ekhaya naphesheya. Ekhuluma ngalokhu, kufanele sikhulume isimo se-decolorizing flocculants ekwelapheni kwamanzi. Ngokuyisisekelo, indle ekhiqizwa izimboni eziningi idinga ukusebenzisa ama-decolorizing flocculants. I-Yixing Cleanwater izokwethula olwazini olufanele kanye nokusetshenziswa emikhakheni ehlukene.
Ama-flocculants ahlukahlukene e-polymer decolorizing asetshenziswa kabanzi emkhakheni wamanzi ezimboni kanye nokwelashwa kwendle phesheya, phakathi kwawo i-polyacrylamide (PAM) iwuhlobo oluyinhloko lwe-decolorizing flocculant. Uma kuqhathaniswa ne-flocculants yendabuko kasawoti we-inorganic, i-PAM, njengohlobo olusha lwe-ejenti yokwelashwa kwamanzi, inezinzuzo eziningi: ilula futhi kulula ukuyisebenzisa, umphumela we-flocculation uphakeme izikhathi eziningi kune-flocculants yendabuko ye-inorganic decolorizing; i-flocculation esheshayo kanye nesivinini se-sedimentation, ukusebenza kahle kokukhipha amanzi ngodaka; umphumela okhethekile wokwelapha emanzini athile angcolile; imishini elula edingekayo, izinyawo ezincane; izindleko eziphansi zokwelashwa; indle ingabuyekezwa futhi isetshenziswe kabusha, njll.
Isicelo seI-PAM decolorizing flocculant emikhakheni ehlukene yohlelo lokusebenza:
1. Isicelo embonini yokwenza iphepha
Ukusebenzisa i-PAM yesisindo samangqamuzana aphezulu njenge-flocculant esusa umbala kungakhuphula izinga lokuna kwemibala nezinye izinto emanzini amhlophe futhi kunciphise ukulahlekelwa kwazo. Ukwengeza i-0.25~0.5% PAM ku-pulp kungakhuphula izinga le-sedimentation ye-pulp izikhathi ezingu-40 ~ 80, ukunciphisa okuqukethwe okuqinile emanzini amhlophe cishe ngo-66%, kwandise okuqukethwe komlotha wephepha, kukhuphule izinga lokugcinwa kwemibala efana nobumba olumhlophe ngo-8~18%, futhi yonge u-20kg we-pulp ngethani lephepha. Ngaphezu kwalokho, ngemva kokusebenzisa i-PAM, ukuthuthumela kwamanzi amhlophe kuyancipha kakhulu, kunciphisa ukungcoliswa kwemvelo. Isibonelo, izinto eziqinile ezimisiwe zamanzi angcolile e-milky amhlophe ane-pH=6.8 angu-3000ppm. Ngemva kokuphathwa nge-PAM nge-hydrolysis degree engu-5 ~ 10%, isisindo samangqamuzana esiyizigidi ezingu-5.5 ~ 10, kanye ne-500ppm ye-aluminium sulfate, amanzi amhlophe angashintshwa abe uketshezi olungenambala futhi olusobala, futhi okuqinile okumisiwe kuyehliswa kube ngaphansi kuka-50ppm.
2. Ukusetshenziswa kwe-decolorizing flocculants ekwelashweni kwamanzi
①I-Anti-scaling kanye nokwehliswa
Emanzini wezimboni kanye nokuhlanza indle, amanzi aluhlaza kufanele aqale acaciswe. I-PAM decolorizing flocculants kanye nama-coagulants e-inorganic avame ukusetshenziswa ngokuhlanganiswa, okunganciphisa kakhulu ukusetshenziswa kwama-coagulants angaphili, ukugwema ukuvinjelwa kwemishini kanye nokugqwala ngenxa yokusetshenziswa ngokweqile kwama-coagulants angaphili, futhi kuvimbele ukwakheka kwesikali. Izingxenye ezingu-37.5 ze-PAM ezinesisindo se-molecular esingaphansi kwesigidi esingu-1 kanye nezingxenye ezingu-50 ze-sodium tripolyphosphate zisetshenziselwa ukwakha i-scale inhibitor, engavimbela ngokuyisisekelo isikali sezishintshisi zokushisa ezilinganiselwe kakhulu.
②Ukwelashwa kwendle yezimboni
3. Ukusetshenziswa kwe-decolorizing flocculants ekuhlanzeni amanzi angcolile embonini kashukela
Ijusi yomoba ekhishwa ezimbonini zikashukela emshinini wokunyathelisa ngokuvamile iba nemfucumfucu futhi nokwakheka kwawo kuyinkimbinkimbi kakhulu. Ukuze kutholwe ijusi yomoba ehlanzekile, kudingeka kufakwe izinto zokucacisa amakhemikhali. Esikhathini esedlule, i-inorganic decolorizing flocculants yayivame ukusetshenziswa, kodwa ngokuthuthukiswa kwemboni kashukela, ama-inorganic decolorizing flocculants awasakwazi ukuhlangabezana nezidingo zokukhiqiza. Eminyakeni yamuva nje, ukusetshenziswa kwe-PAM embonini kashukela kungakhuphula izinga le-sedimentation izikhathi ezingu-20.
Kafushane, lapho sikhetha i-polyacrylamide PAM decolorization flocculant ngokuya ngesimo sangempela, kufanele siyikhethe ngokuya ngezimo nemibandela ehlukene yohlelo lokusebenza. Ngakho-ke, ukukhethwa kwe-polyacrylamide nakho kubaluleke kakhulu.
Uma udinga imikhiqizo yethu, sicela ukhululekeXhumana nathi!
