Kwindawo yanamhlanje, iingxaki zelindle ezibangelwa luphuhliso lwemizi-mveliso ziye zaphathwa ngokufanelekileyo ekhaya nakwamanye amazwe. Sithetha ngale nto, kufuneka sikhankanye imeko ye-flocculants esusa umbala ekucoceni amanzi. Ngokusisiseko, i-lindle eveliswa ngamashishini amaninzi kufuneka isebenzise i-flocculants esusa umbala. I-Yixing Cleanwater iya kukwazisa ulwazi olufanelekileyo kunye nokusetyenziswa kwiindawo ezahlukeneyo.
Ii-flocculants ezahlukeneyo ezisusa umbala kwi-polymer zisetyenziswa kakhulu kwicandelo lokunyanga amanzi amdaka kwimizi-mveliso nakwamanye amazwe, apho i-polyacrylamide (PAM) lolona hlobo luphambili lwe-flocculant esusa umbala. Xa kuthelekiswa ne-flocculants zetyuwa ezingaphiliyo, i-PAM, njengohlobo olutsha lwearhente yonyango lwamanzi, ineengenelo ezininzi: ilula kwaye kulula ukuyisebenzisa, isiphumo se-flocculation siphezulu kakhulu kune-flocculants zetyuwa ezingaphiliyo; isantya se-flocculation esikhawulezayo kunye nesantya se-sedimentation, ukusebenza kakuhle kokukhupha amanzi ngodaka; isiphumo sonyango olukhethekileyo kwi-sediment ethile; izixhobo ezilula ezifunekayo, indawo encinci; iindleko zonyango eziphantsi; i-sediment ingaphinda isetyenziswe kwaye isetyenziswe kwakhona, njl.
Ukusetyenziswa kweI-flocculant yokususa umbala kwi-PAM kwiindawo ezahlukeneyo zesicelo:
1. Ukusetyenziswa kwishishini lokwenza amaphepha
Ukusebenzisa i-PAM enobunzima obukhulu njenge-flocculant esusa umbala kunokunyusa izinga lokuna kwemibala kunye nezinye izinto emanzini amhlophe kwaye kunciphise ukulahleka kwazo. Ukongeza i-0.25 ~ 0.5% ye-PAM kwi-pulp kunokunyusa izinga lokutsalwa kwe-pulp ngamaxesha angama-40 ~ 80, ukunciphisa umxholo oqinileyo emanzini amhlophe malunga ne-66%, ukwandisa umxholo womlotha wephepha, ukwandisa izinga lokugcina imibala efana nodongwe olumhlophe nge-8 ~ 18%, kwaye konge i-20kg ye-pulp ngetoni nganye yephepha. Ngaphezu koko, emva kokusebenzisa i-PAM, ukungcoliseka kwamanzi amhlophe kuyancipha kakhulu, kunciphisa ungcoliseko lokusingqongileyo. Umzekelo, izinto eziqinileyo ezixhonyiweyo zamanzi amdaka e-milky white pulp ane-pH = 6.8 yi-3000ppm. Emva kokunyangwa nge-PAM nge-hydrolysis degree ye-5 ~ 10%, ubunzima be-molecular be-5.5 ~ 10 yezigidi, kunye ne-500ppm ye-aluminium sulfate, amanzi amhlophe anokuguqulwa abe lulwelo olungenambala nolucacileyo, kwaye izinto eziqinileyo ezixhonyiweyo zincitshiswa zibe ngaphantsi kwe-50ppm.
2. Ukusetyenziswa kwee-flocculants ezisusa umbala kunyango lwamanzi
①Ukungakhulisi nokunciphisa iikali
Kwindlela yokucoca amanzi kunye nelindle kwimizi-mveliso, amanzi aluhlaza kufuneka aqale acaciswe. Ii-flocculants ezisusa umbala kwi-PAM kunye nee-coagulants ezingaphiliyo zihlala zisetyenziswa kunye, nto leyo enokunciphisa kakhulu ukusetyenziswa kwee-coagulants ezingaphiliyo, ithintele ukuvaleka kwezixhobo kunye nokugqwala ngenxa yokusetyenziswa kakhulu kwee-coagulants ezingaphiliyo, kwaye ithintele ukwakheka kwesikali. Iinxalenye ezingama-37.5 ze-PAM ezinobunzima beemolekyuli ezingaphantsi kwesigidi esi-1 kunye neenxalenye ezingama-50 ze-sodium tripolyphosphate zisetyenziselwa ukwenza isikali esithintelayo, esinokuthintela isikali see-heat exchangers ezilinganiswe kakhulu.
②Unyango lwelindle lemizi-mveliso
3. Ukusetyenziswa kwe-flocculants yokususa umbala kunyango lwamanzi amdaka kwishishini leswekile
Ijusi yomoba ekhutshwa kwi-press ziifektri zeswekile idla ngokuba yi-dumbbid kwaye ukwakheka kwayo kuyinkimbinkimbi kakhulu. Ukuze kufunyanwe ijusi yomoba ecocekileyo, kufuneka kongezwe izihluzi zeekhemikhali. Ngaphambili, ii-flocculants ezisusa umbala kwi-inorganic zazisetyenziswa rhoqo, kodwa ngophuhliso lweshishini leswekile, ii-flocculants ezisusa umbala kwi-inorganic azisakwazi ukuhlangabezana neemfuno zemveliso. Kwiminyaka yakutshanje, ukusetyenziswa kwe-PAM kwishishini leswekile kunokunyusa izinga lokutsalwa kwetyuwa ngama-20.
Ngamafutshane, xa sikhetha i-polyacrylamide PAM decolorization flocculant ngokwemeko yokwenyani, kufuneka siyikhethe ngokweemeko ezahlukeneyo zokusetyenziswa kunye neemeko. Ke ngoko, ukukhetha i-polyacrylamide nako kubaluleke kakhulu.
