Polyaluminium kloride:PAC mwachidule, yomwe imadziwikanso kuti basic aluminium chloride kapena hydroxyl aluminium chloride.
Mfundo:kudzera mu hydrolysis mankhwala a polyaluminium kolorayidi kapena polyaluminium mankhwala enaake, mpweya colloidal mu zimbudzi kapena sludge mofulumira anapanga, amene n'zosavuta kupatukana lalikulu particles wa mpweya.Kachitidwe:Mawonekedwe ndi magwiridwe antchito a PAC amagwirizana ndi alkalinity, njira yokonzekera, kapangidwe kazonyansa ndi zomwe zili ndi alumina.
1, pamene alkalinity wa koyera madzi polyaluminium kolorayidi ndi mkati osiyanasiyana 40% ~ 60%, ndi kuwala chikasu mandala madzi.Pamene alkalinity ndi yoposa 60%, pang'onopang'ono imakhala madzi osawoneka bwino.
2, pamene alkalinity ndi zosakwana 30%, olimba polyaluminium kolorayidi ndi mandala.
3, pamene alkalinity ili mkati mwa 30% ~ 60%, ndi colloidal zakuthupi.
4, pamene alkalinity ndi wamkulu kuposa 60%, pang'onopang'ono amakhala galasi kapena resin.Solid polyaluminium kolorayidi zopangidwa ndi bauxite kapena dongo mchere ndi chikasu kapena zofiirira.

22-24% zomwe zili:ng'oma kuyanika ndondomeko kupanga, popanda mbale ndi chimango kusefa, madzi insoluble zinthu ndi apamwamba, ndi panopa mtengo msika wa mankhwala mafakitale, makamaka ntchito mankhwala otayidwa mafakitale mafakitale.
26% yazinthu:ng'oma kuyanika ndondomeko kupanga, popanda mbale ndi chimango zosefera, madzi insoluble zinthu ndi otsika kuposa 22-24%, mankhwala ndi muyezo dziko lonse mafakitale kalasi, mtengo ndi apamwamba pang'ono, makamaka ntchito mafakitale zinyalala mankhwala.
28% yazinthu:izi ali ndi mitundu iwiri ya ndondomeko ya ng'oma kuyanika ndi utsi kuyanika, madzi kudzera mbale chimango fyuluta, madzi insoluble kuposa woyamba awiri otsika, ndi PAC mankhwala apamwamba kalasi, angagwiritsidwe ntchito otsika turbidity zimbudzi mankhwala ndi mpopi madzi chomera pretreatment.
30% yazinthu:pali mitundu iwiri ya ng'oma kuyanika ndi utsi kuyanika, mayi madzi kudzera mbale chimango fyuluta, ali apamwamba kalasi mankhwala PAC, makamaka ntchito pa chomera madzi wapampopi ndi otsika turbidity wa mankhwala m'nyumba.
32% yazinthu:izi zimapangidwa ndi kuyanika kutsitsi, ndizosiyana ndi zinthu zina, mawonekedwe a PAC awa ndi oyera, ndi oyera kwambiri omwe si achitsulo polyaluminium chloride, omwe amagwiritsidwa ntchito kwambiri m'mafakitale abwino opangira mankhwala ndi zodzoladzola, amakhala mgulu lazakudya.
Polyacrylamide:yotchedwa PA M, yomwe imadziwika kuti flocculant kapena coagulant
Mfundo:PAM unyolo wa molekyulu ndi gawo lobalalika kudzera mumitundu yosiyanasiyana yamakina, thupi, mankhwala ndi zina, gawo lobalalika limalumikizidwa palimodzi, kupanga maukonde, motero kukulitsa gawolo.
Kachitidwe:PAM ndi ufa woyera, sungunuka m'madzi, pafupifupi insoluble mu benzene, etha, lipids, acetone ndi zina zonse organic solvents, polyacrylamide amadzimadzi njira ndi pafupifupi mandala viscous madzi, ndi sanali owopsa katundu, sanali poizoni, sanali zikuwononga, olimba. PAM ili ndi hygroscopicity, hygroscopicity imawonjezeka ndi kuwonjezeka kwa digiri ya ionic.

PAM malinga ndi makhalidwe ake a gulu dissociable anawagawa anionic Polyacrylamide, cationic Polyacrylamide ndi sanali ionic Polyacrylamide.Ionic polyacrylamide.
Cationic PAM:adamulowetsa sludge opangidwa ndi biochemical njira
Anionic PAM:zimbudzi ndi sludge ndi mlandu zabwino, monga zitsulo chomera, electroplating chomera, zitsulo, kutsuka malasha, kuchotsa fumbi ndi zimbudzi zina, ndi zotsatira bwino
Nonionic PAM:pakuti cationic ndi anionic zimakhala ndi zotsatira zabwino, koma mtengo wake ndi wokwera mtengo kwambiri, nthawi zambiri sagwiritsidwa ntchito kawirikawiri

Kodi flocculation ndi chiyani? Pambuyo powonjezera coagulant kumadzi osaphika, kusakanikirana kwathunthu ndi thupi lamadzi, zonyansa zambiri za colloid m'madzi zimataya kukhazikika, ndipo tinthu tating'onoting'ono ta colloid timagundana ndikulumikizana wina ndi mnzake mu dziwe la flocculation, ndiyeno kupanga floc yomwe imatha kuchotsedwa ndi njira yamvula.
Zomwe zimayambitsa za flocculation
Njira ya kukula kwa floc ndi njira yolumikizana ndi kugunda kwa tinthu tating'onoting'ono.
Ubwino wa flocculation zotsatira zimadalira zinthu ziwiri zotsatirazi:
1 kuthekera kwa ma polima opangidwa ndi coagulant hydrolysis kuti apange adsorption chimango mlatho, womwe umatsimikiziridwa ndi katundu wa coagulants.
2 kuthekera kwa kugunda kwa tinthu tating'onoting'ono komanso momwe mungawathandizire kuti azitha kugundana koyenera komanso kothandiza.Malangizo opangira mankhwala amadzi amakhulupilira kuti kuti awonjezere kuthekera kwa kugundana, liwiro lokwera liyenera kuwonjezeka, komanso kugwiritsa ntchito mphamvu kwamadzi am'madzi kuyenera kukhala. kuchulukitsidwa pakuwonjezeka kwa liwiro, ndiko kuti, kukulitsa kuthamanga kwa dziwe la flocculation (chowonjezera: ngati tinthu tating'ono tating'ono tating'ono tating'ono tating'ono tating'ono tating'ono tating'ono tating'ono ta flocculation, titha kuwonongedwa. Pali mavuto awiri: 1 floc kukula mwachangu kwambiri mphamvu yake ndi kufooka, mu otaya ndondomeko anakumana kukameta ubweya amphamvu adzapanga adsorption chimango mlatho kudulidwa, kudula adsorption chimango mlatho n'zovuta kupitiriza mmwamba, kotero ndondomeko flocculation ndi ndondomeko yochepa, ndi kukula kwa floc, kuyenda liwiro ayenera. kuchepetsedwa, kotero kuti anapanga floc n'kovuta kuti wosweka 2 ena floc mofulumira kukula adzapanga madzi floc enieni padziko m'dera lakuthwa yafupika, ena anachita si wangwiro particles anataya anachita zinthu, izi particles ang'onoang'ono ndi particles lalikulu kugunda; Mwinanso yafupika kwambiri, ndizovuta kukulanso, tinthu tating'onoting'ono tating'ono tating'ono tomwe timasungidwa, ndizovutanso kusunga fyuluta.)
Onjezani zofunika
Kumayambiriro kwa zochita za kuwonjezera coagulant, m`pofunika kuonjezera mwayi kukhudzana ndi zimbudzi mmene ndingathere, kuonjezera kusanganikirana kapena otaya mlingo.Malingana ndi kugunda kwa madzi otaya ndi lopinda mbale ndi otaya madzi pakati. Kupinda mbale kuonjezera liwiro, kuti madzi particles kugunda mwayi ukuwonjezeka, kotero kuti floc condensation.Ndipo mochedwa anachita, pofuna kuchepetsa liwiro gradient, akhoza bwino flocculation, mpweya kwenikweni.
Zowonjezera zida:chidebe cha mankhwala, thanki yosungiramo mankhwala, choyambitsa dosing, mpope wa dosing ndi zida zoyezera.Okonzeka ndi kugwiritsa ntchito njira
PAC, PAM dispensing concentration (yotengedwa m'thumba la mankhwala ndi kuwonjezeredwa ku thanki yowonongeka) PAC ndi PAM yogawa ndende Malingana ndi zomwe zinachitikira: PAC dissolution pool concentration ya 5% -10%, PAM concentration ya 0.1% -0.3%, the pamwamba deta mogwirizana ndi khalidwe, ndiko kuti, aliyense kiyubiki madzi PAC 50-100kg, PAM 1-3kg. ndende Izi ndi mkulu, PAM Kutha mphamvu ndi ochepa, ayenera kusonkhezera mokwanira oyambitsa sing'anga liwiro kuti kotheratu dissolved. Kusungunuka kwa PAM kumatha kukulitsidwa bwino mpaka 0.3-0.5%.Tengani PAC kuvunda ndende ya 10%, PAM kuvunda ndende ya 0.5%, ndiye aliyense kiyubiki madzi kusungunuka PAC100kg, PAM5kg, kusintha diaphragm otaya mita mpope otaya, malinga 1 kiyubiki mita. / 24 hours mawerengedwe, ndiye, Q = 42 malita / ola, akhoza kukwaniritsa abwino zimbudzi mankhwala flocculation kwenikweni.PAC, PAM sewage treatment agent mlingo (kusungunuka m'madzi oyambirira) Mlingo wa wothandizila zachimbudzi nthawi zambiri ndi PAC 50-100ppm, PAM 2-5ppm, ppm unit ndi miliyoni imodzi, kotero amasandulika 50-100 magalamu a PAC pa tani ya zimbudzi, 2-5 magalamu a PAM, tikulimbikitsidwa kuti kawirikawiri molingana ndi mayesowa a mlingo.Ngati mphamvu yachimbudzi ya tsiku ndi tsiku ndi 2000 cubic metres, PAC mlingo wa PAC malinga ndi 50ppm, PAM mlingo wa ndende malinga ndi 2ppm mawerengedwe, ndiye tsiku lililonse mlingo wa PAC ndi 100kg, mlingo wa PAM ndi 4kg. Mlingo womwe uli pamwambawu umawerengedwa molingana ndi zochitika zambiri, mlingo weniweni ndi ndondomeko ya mlingo uyenera kukhazikitsidwa pa kuyesa kwapadera kwa madzi.Werengani mtengo womwe wakhazikitsidwa mu mita yotaya pampu ya dosing
Pambuyo powonjezera wothandizira ku zimbudzi kapena sludge, ziyenera kusakanikirana bwino.Nthawi yosakaniza nthawi zambiri imakhala masekondi 10-30, nthawi zambiri osapitilira mphindi ziwiri.Mlingo yeniyeni wa wothandizira ndi ndende ya colloidal particles, inaimitsidwa zolimba mu zinyalala kapena sludge, chikhalidwe ndi mankhwala zida ndi ubale waukulu, sludge mankhwala mlingo kwa ena, mlingo wabwino kwambiri analandira kudzera ambiri experiments.According to Mlingo wabwino kwambiri wa mlingo (ppm1 kuti muwonjezere ndende) ndi kutuluka kwa madzi (t/h) ndi kasinthidwe ka ndende ya yankho (ppm2 kukonzekera ndende), zitha kuwerengedwa pamtengo wowonetsa pampu flowmeter display value (LPM). dosing mpope flowmeter (LPM) = madzi otaya (t/h)/60×PPM1 kuwonjezera ndende /PPM2 kukonzekera ndende.
Zindikirani: ppm ndi miliyoni imodzi; mlingo wa pump flowmeter value units, LPM ndi malita/miniti;GPM ndi magaloni/miniti
