Yintoni ehanjiswayo namhlanje yiseti yezixhobo zomatshini we-flotation wokucoca ukungcola kwiPhepha lokusila!
Izixhobo zokucocwa kwamanzi amdaka ngamaphepha-Umatshini wokuNyulwa koMoya oNyibilikileyoibhekisa kwizixhobo ezinciphisa i-SS kunye neCOD kumanzi amdaka aveliswa lishishini lephepha, ngenjongo yokunciphisa iingozi zongcoliseko.
Ishishini lephepha lelinye lamashishini asebenzisa amandla aphezulu kunye nongcoliseko olukhulu lokusingqongileyo.Ungcoliseko lokusingqongileyo olubangelwa kuko luphawulwa ngobuninzi bokukhutshwa kwamanzi amdaka, imfuno ephezulu ye-oksijini ye-Biochemical (BOD), kunye ne-fiber eninzi emisiwe emanzini amdaka, equlethe i-Hemicellulose, i-lignin, i-Mineral acid salts, i-fibers emihle, i-inorganic. izihluzi, i-inki yokushicilela, iidayi, namanzi amdaka kunye negesi eyinkunkuma equlethe i-divalent sulfur, enevumba elibi nombala.I-Lignin kunye ne-Hemicellulose ikakhulu zenza i-COD kunye ne-BOD yamanzi amdaka;Iifiber ezincinci, iifayili ze-inorganic, njl njl kufuneka zenze i-SS;I-inki, iidayi, njl njl. ikakhulu zenza ichromaticity kunye neCOD.Ezi zingcolisi zibonakalisa ngokubanzi izikhombisi eziphezulu ze-SS kunye ne-COD zamanzi amdaka.
Izixhobo zokucocwa kwamanzi amdaka ezenziwe ngamaphepha-Umatshini wokuNyulwa koMoya oNyibilikileyoinokunciphisa i-SS kunye ne-COD kumanzi amdaka ngoncedo lwee-chemical flocculants.Kwishishini lokwenza iphepha, esi sixhobo singasetyenziselwa unyango lomatshini wephepha wamanzi amhlophe kunye namanzi amdaka aphakathi anje nge-deinking amanzi amdaka.Ngakolunye uhlangothi, inokubuyisela iintsinga, kwaye kwelinye icala, ingaphinda isebenzise okanye ikhuphe amanzi amdaka acociweyo ukuhlangabezana nemigangatho, ukunciphisa kakhulu uxinzelelo kukhuseleko lokusingqongileyo.Esi sixhobo siyilwe ngokweeprototypes ezidumileyo eUnited States, ngetekhnoloji ephucukileyo, ulwakhiwo olulula, kunye nolondolozo olufanelekileyo
Ukuqukuqela okuthe tyeUmatshini wokuNyulwa koMoya oNyibilikileyosisixhobo sokwahlula esilulwelo esisetyenziswa ngokuqhelekileyo kushishino lokucoca ilindle, esinokususa ngokufanelekileyo izinto eziqinileyo ezimisiweyo, igrisi, kunye neentsini kugutyulo.Sesona sixhobo siphambili sokucocwa kwelindle kwangoko.
1. Iimpawu zesakhiwoUmatshini wokuNyulwa koMoya oNyibilikileyo: Umzimba oyintloko wesixhobo sisakhiwo sentsimbi esixande.Amacandelo aphambili aqulunqwe yimpompo yomoya enyibilikileyo, i-compressor yomoya, itanki yomoya enyibilikileyo, ibhokisi yoxande, inkqubo yokujikeleza komoya, inkqubo yokukhuhla udaka, njl.
1I-tank yegesi ivelisa amaqamza amancinci kunye nobukhulu be-particle ye-20-40um, kwaye i-adhesive flocculent iqinile, enokufikelela kwisiphumo esihle sokuhamba emoyeni;
2Ukusetyenziswa okuncinci kweeflocculants kunye neendleko ezincitshisiweyo;
3）.Iinkqubo zokusebenza zilula ukuyiqonda, umgangatho wamanzi kunye nobuninzi bulula ukulawula, kwaye ulawulo lulula;
4）.Ukuxhotyiswa ngenkqubo yokuhlamba umva, isixhobo sokukhulula asivalwanga lula.
2. Umgaqo wokuSebenza weUmatshini wokuNyulwa koMoya oNyibilikileyo: Itanki yegesi ivelisa amanzi anyibilikisiweyo, akhutshwa emanzini ukuba aphathwe ngesixhobo soxinzelelo.Umoya onyibilikisiweyo emanzini uphuma emanzini, wenze amaqamza amancinci angama-20-40um.Amaqamza amancinci adityaniswa nezinto eziqinileyo ezinqunyanyisiweyo kugutyulo, enze ubunzima obuthile bezinto eziqinileyo ezinqunyanyisiweyo zibe mncinci kunezo zamanzi kwaye ngokuthe ngcembe zidada kumphezulu ukuze zenze umgquba.Kukho inkqubo ye-scraper kumphezulu wamanzi ukukrazula i-scum kwi-tank ye-sludge.Amanzi acocekileyo angena kwitanki yamanzi acocekileyo ngomjelo wokuphuphuma kwamanzi ukusuka ezantsi.
3. Umda wokusetyenziswa kwe Umatshini wokuNyulwa koMoya oNyibilikileyo:
1) Isetyenziselwa ukususa izinto eziqinileyo ezimisiweyo, amafutha, kunye nezinto ezahlukeneyo ze-colloidal kumanzi amdaka, njengokucocwa kwamanzi amdaka kumashishini anje ngepetrochemical, imigodi yamalahle, ukwenza iphepha, ukuprinta kunye nokudaya, ukuxhela kunye nokutywala;
2).Isetyenziselwa ukurisayikilishwa kwezinto eziluncedo, ezifana nokuqokelelwa kweentsinga ezicolekileyo kumanzi amhlophe okwenza iphepha.
