Ukucocwa kwamanzi amdaka yinkqubo enzima efuna ukusetyenziswa kweekhemikhali ezahlukeneyo ukunceda ukuhlambulula amanzi.I-flocculants yenye yeekhemikhali ezibalulekileyo ezidlala indima ebalulekileyo kwinkqubo yokucocwa kwamanzi amdaka.Eli nqaku liza kwazisa ngokweenkcukacha idosi yeekhemikhali zokucoca ugutyulo, amashishini esicelo se-flocculants kunyango lwamanzi amdaka, indima yeekhemikhali zelindle, kunye nezilumkiso zokusebenzisa i-flocculants.
Umthamo weekhemikhali zokucocwa kwamanzi amdaka kuxhomekeke kumgangatho wamanzi amdaka, inkqubo yonyango kunye neemeko zangempela.Le ilandelayo yimizekelo yeedosi zemichiza eqhelekileyo yokucoca ilindle:
Ipolyaluminiyam chloride (PAC):Ngokuqhelekileyo isetyenziswe njenge-flocculant, inokusabela ngamasuntswana e-colloidal ahlawuliswa kakubi ukuvelisa i-hydroxide micelles yokumisa ukususa izinto eziqinileyo kunye ne-ion zetsimbi enzima.Kwiimeko eziqhelekileyo, idosi ngetoni yamanzi akrwada imalunga namashumi amagremu, kodwa idosi eyiyo kufuneka ihlengahlengiswe ngokomgangatho wamanzi akrwada kunye neemeko zenkqubo.
I-Polyacrylamide (PAM):isetyenziswe njenge-coagulant ukuphucula ukuqina kunye nokuzinza kwe-floc.Ngokuqhelekileyo isetyenziswe ngokubambisana ne-polyaluminium chloride, i-dosage ngetoni yamanzi akrwada imalunga neegremu ezimbalwa, kodwa eyona dosi kufuneka ilungiswe ngokufanelekileyo ngokwemiqathango yenkqubo kunye neentlobo zezinto ezingcolisayo.
Iiflocculants zisetyenziswa kakhulu kunyango lwamanzi amdaka, ikakhulu kubandakanywa ezi ndidi zilandelayo:
Ukucocwa kwamanzi amdaka kwimizi-mveliso: Amanzi amdaka akwimizi-mveliso aqulethe isixa esikhulu sezinto eziqinileyo ezinqunyanyisiweyo, ii-ion zesinyithi esinzima kunye nezingcolisi eziphilayo.Ukusetyenziswa kwe-flocculants kunokususa ngokufanelekileyo oku kungcola kunye nokucoca amanzi amdaka.
Ukucocwa kwamanzi amdaka asekhaya: Ilindle lasekhaya liqulethe isixa esikhulu sezinto eziphilayo kunye nezinto eziqinileyo ezixhonyiweyo.Ukusetyenziswa kwe-flocculants kunokususa ngokufanelekileyo ezi zinto zingcolileyo kunye nokuphucula umgangatho wamanzi.
Ukucocwa kwamanzi amdaka asefama: Amanzi amdaka asefama aqulethe isixa esikhulu sezinto eziphilayo, i-ammonia nitrogen kunye nezinye izinto eziyingozi.Ukusetyenziswa kwe-flocculants kunokususa ngokufanelekileyo ezi zinto zingcolileyo kunye nokuphucula umgangatho wamanzi.
Amanzi amdaka emizi-mveliso: Ukusetyenziswa kweeflocculants kunokususa ngokufanelekileyo izinto eziqinileyo ezimisiweyo, ii-ion zesinyithi esinzima kunye nezingcolisi eziphilayo emanzini kunye nokuphucula umgangatho wamanzi.
Imisebenzi yemichiza yogutyulo ibandakanya ikakhulu ezi ndidi zilandelayo:
Ukususwa kwezinto eziqinileyo ezinqunyanyisiweyo: Ngokusebenzisa i-flocculants, izinto eziqinileyo ezinqunyanyisiweyo kumanzi amdaka ziyadityaniswa zibe ziziqhuma ukwenzela ukuba kube lula ukuntywila kunye nokuhluzwa.
Ukususwa kwee-ion zentsimbi enzima: Ngokusetyenziswa kwee-flocculants, ii-ion zetsimbi ezinzima emanzini amdaka ziguqulwa zibe yi-hydroxide precipitates ukuze zisuswe lula.
Ukususwa kwezinto ezingcolisayo eziphilayo: Ngokusebenzisa i-flocculants, ukungcola kwezinto eziphilayo kumanzi amdaka aguqulwa abe yi-hydroxide precipitates okanye i-oxidized kwezinye izinto ukuze zisuswe lula.
Uhlengahlengiso lwe-pH: Lungisa i-pH yamanzi amdaka ngokusebenzisa isenzo sealkali okanye iasidi ukucoca amanzi amdaka.
Izinto ekufuneka uziqwalasele xa usebenzisa i-flocculants:
Khetha i-flocculant efanelekileyo: Iiflocculants ezahlukeneyo zinemisebenzi eyahlukeneyo kunye nemiphumo.Kuyimfuneko ukuba ukhethe i-flocculant efanelekileyo ngokweyona meko.
Lawula idosi yeyeza: Ukungonelanga kwedosi kuya kuchaphazela umphumo, kwaye umthamo ogqithisileyo uya kubangela inkunkuma kunye nokulahlekelwa kwezoqoqosho.Ngoko ke, kuyimfuneko ukulawula idosi efanelekileyo ngokweyona meko.
Gxuma ngokucokisekileyo: Gxuma i-flocculant kunye namanzi ngokucokisekileyo ukuze unyibilike ngokupheleleyo kwaye usabele.
Nika ingqalelo kwiqondo lokushisa kunye nexabiso le-pH: Ubushushu kunye nexabiso le-pH linempembelelo kwimpembelelo ye-flocculant kwaye kufuneka ilawulwe ngononophelo.
