Polyaluminium chloride:PAC kwenguva pfupi, inozivikanwawo seyakakosha aluminium chloride kana hydroxyl aluminium chloride.
Musimboti:kuburikidza ne hydrolysis chigadzirwa che polyaluminium chloride kana polyaluminium chloride, iyo colloidal precipitation mumvura yetsvina kana sludge inokurumidza kuumbwa, iyo iri nyore kuparadzanisa zvidimbu zvakakura zvemvura.Kuita:Kutaridzika uye kuita kwePAC kune hukama nealkalinity, nzira yekugadzirira, kusachena kuumbwa uye alumina zvemukati.
1, kana alkalinity ye pure liquid polyaluminium chloride iri mukati me 40% ~ 60%, imvura yero yakajeka inoonekera.Kana iyo alkalinity inopfuura 60%, zvishoma nezvishoma inova isina ruvara inopenya mvura.
2, apo alkalinity iri pasi pe30%, yakasimba polyaluminium chloride irenzi.
3, kana iyo alkalinity iri mukati mechikamu che30% ~ 60%, icolloidal material.
4, apo alkalinity yakakura kudarika 60%, zvishoma nezvishoma inova girazi kana resin.Solid polyaluminium chloride yakagadzirwa nebauxite kana yevhu yemaminerari ndeyero kana shava.

Polyacrylamide:inonzi PA M, inowanzozivikanwa se flocculant kana coagulant
Musimboti:PAM molecular chain uye chikamu chakapararira kuburikidza nemhando dzakasiyana-siyana dzemuchina, muviri, kemikari uye zvimwe zvinokonzeresa, chikamu chakapararira chakabatana pamwe chete, kugadzira network, nekudaro kusimudzira basa.
Kuita:PAM iupfu chena, inonyungudika mumvura, inenge isinganyungudike mubenzene, ether, lipids, acetone nezvimwe zvinonyungudutsa zvega zvega, polyacrylamide aqueous solution inenge iri transparent viscous fluid, is a non-dangerery goods, non-toxic, non-corrosive, solid. PAM ine hygroscopicity, hygroscopicity inowedzera nekuwedzera kweionic degree.

Chii chinonzi flocculation?Mushure mekuwedzera coagulant kumvura mbishi, kusanganiswa zvizere nemuviri wemvura, yakawanda yetsvina yecolloid iri mumvura inorasikirwa nekugadzikana, uye iyo isingagadzike colloid particles inodhumhana uye kudhumhana mune imwe flocculation pool, yobva yagadzira floc inogona kubviswa nenzira yekunaya.
Izvo zvinofurira zvinhu zve flocculation
Iyo nzira yekukura kwefloc ndiyo nzira yekubata uye kudhumhana kwezvimedu zvidiki.
Hunhu hwe flocculation effect hunoenderana nezvinhu zviviri zvinotevera:
1 kugona kwepolymer complexes inoumbwa necoagulant hydrolysis kuumba adsorption furemu bhiriji, iro rinotemerwa nezvimiro zvecoagulants.
2 mukana wekudhumhana kwezvimedu zvidiki uye kuti ungazvidzora sei kune zvine musoro uye zvinobudirira kudhumhana.Marapirwo einjiniya ekurapwa kwemvura anotenda kuti kuitira kuti kuwedzere mukana wekudhumhana, kumhanya kunofanirwa kuwedzerwa, uye kushandiswa kwesimba kwemuviri wemvura kunofanirwa kunge kuri. kuwedzera nekuwedzera speed gradient, ndiko kuti, kuwedzera kuyerera kwechidziva cheflocculation (addendum: kana zvimedu zvikaungana uye zvikakura nekukurumidza mukubhururuka, zvichaparadzwa. Pane matambudziko maviri: 1 floc kukura zvakanyanya nekukurumidza simba rayo isina simba, mukuyerera kwakasangana nekuveura kwakasimba kuchaita kuti adsorption furemu zambuko rigurwe, iyo yakatemwa adsorption furemu bhiriji yakaoma kuenderera kumusoro, saka iyo flocculation process zvakare ishoma maitiro, nekukura kwefloc, kuyerera kwevhavha kunofanirwa. kuderedzwa, kuitira kuti kuumbwa floc hakusi nyore kuputswa 2 vamwe floc kukurumidza kukura kuchaita kuti mvura floc chaiyo pamusoro nharaunda inopinza kuderedzwa, vamwe kuita haisi akakwana particles akarasika maitiro ezvinhu, zvidimbu izvi zviduku uye hombe particles kudhumhana; mukana wakaderedzwa zvakanyanya, zvakaoma kukura zvakare, zvimedu izvi hazvigone chete kune sedimentation tank yakachengetwa, zvakare zvakaoma kuchengetedza sefa.)
Wedzera zvinodiwa
Muchikamu chekutanga chekuita kwekuwedzera coagulant, zvakakosha kuwedzera mukana wekubatana netsvina zvakanyanya sezvinobvira, kuwedzera kusanganiswa kana kuyerera kwehuwandu.Zvichienderana nekudhumhana kwekuyerera kwemvura uye kupeta ndiro uye kuyerera kwemvura pakati. kupeta ndiro kuwedzera kumhanya, kuitira kuti mvura zvimedu kudhumhana mukana kuwedzera, kuti floc condensation.Uye kuti kunonoka kuita, kuitira kuderedza kumhanya gradient, anogona kuwana nani flocculation, kunaya mugumisiro.
Kuwedzera midziyo:mudziyo wezvinodhaka, tangi rekuchengetedza zvinodhaka, dosing stirrer, dosing pombi uye metering michina.Yakashongedzerwa nekushandisa nzira
PAC, PAM yekuisa pfungwa (yakatorwa kubva mubhegi rekurongedza zvinodhaka uye yakawedzerwa kune tangi yekunyungudika) PAC nePAM yekuparadzira concentration Maererano nechiitiko: PAC dissolution pool concentration ye5% -10%, PAM concentration ye0.1% -0.3%, iyo pamusoro pe data maererano nehuhu, kureva, yega yega cubic mvura PAC 50-100kg, PAM 1-3kg.Iyi fungidziro yakakwira zvishoma, PAM yekuparara kwesimba ishoma, inoda kunyandura yakazara inonyandura yepakati kumhanya kusvika yakanyungudika zvachose. PAM dissolution concentration inogona kunyatsowedzerwa kusvika 0.3-0.5%.Tora PAC dissolution concentration ye10%, PAM dissolution concentration ye0.5%, then every cubic water yakanyungudutswa PAC100kg, PAM5kg, gadzirisa diaphragm flow meter pump flow, zvichienderana ne1 cubic mita. / 24 maawa kuverenga, kureva kuti, Q = 42 malita / awa, inogona kuwana yakanakira sewage treatment flocculation effect.PAC, PAM sewage treatment agent dosage (yakanyungudika mumvura yepakutanga)Sewage treatment agent dosage inowanzo PAC 50-100ppm, PAM 2-5ppm, ppm unit imiriyoni imwe, saka inoshandurwa kuita 50-100 magiramu ePAC patani yetsvina, 2-5 magiramu ePAM, zvinokurudzirwa kuti kazhinji zvinoenderana neiyi dosage kuyedzwa.Kana zuva rega rega rekuchenesa tsvina iri 2000 cubic metres, PAC dosage concentration zvinoenderana ne50ppm, PAM dosage concentration zvinoenderana ne2ppm calculation, saka mazuva ese PAC dosage is 100kg, PAM dosage ndeye 4kg. Iyo iri pamusoro peyero inotarwa zvichienderana neruzivo rwese, iyo chaiyo dosage uye dosage yekumisikidza inofanirwa kuve yakavakirwa pane chaiyo kuyedza yemhando yemvura.Verenga kukosha kweseti mune dosing pombi kuyerera mita
Mushure mekuwedzera mumiririri kune tsvina kana sludge, inofanira kunyatsosanganiswa.Nguva yekusanganisa kazhinji 10-30 masekonzi, kazhinji isingapfuuri maminetsi maviri.Iyo chaiyo dosage yemumiririri uye kuungana kwecolloidal particles, yakaturikwa yakasimba mutsvina kana sludge, hunhu nemidziyo yekurapa zvine hukama hukuru, sludge kurapwa dosage kune vamwe, iyo yakanakisa dosage inowanikwa kuburikidza nenhamba huru yekuedza.According to The best dosage concentration (ppm1 kuwedzera concentration) uye kuyerera kwemvura (t/h) uye configuration of the solution concentration (ppm2 preparation concentration), inogona kuverengerwa padosing pump flowmeter display value (LPM) . dosing pombi flowmeter (LPM) = kuyerera kwemvura (t/h)/60×PPM1 kuwedzera fungidziro /PPM2 kugadzirira kusungwa.
Cherechedza: ppm imiriyoni imwe; dosing pombi flowmeter value units, LPM imarita/miniti;GPM imarita/miniti
