PAC / PAM Txoj Kev Siv

Polyaluminium chloride:PAC rau luv luv, tseem hu ua kev yooj yim txhuas chloride lossis hydroxyl txhuas chloride.

Lub hauv paus ntsiab lus:Los ntawm cov khoom siv hydrolysis ntawm polyaluminum chloride lossis polyaluminum cov tshuaj tsw qab, sludge tau yooj yim tsim, uas yog ib qho yooj yim cais cov khoom loj ntawm nag lossis daus.Performance:Cov tsos thiab kev ua tau zoo ntawm PAC muaj feem cuam tshuam rau Alkalinity, npaj txoj kev, impred muaj pes tsawg leeg thiab alumina cov ntsiab lus.

1, thaum ib qho Alkalination ntawm cov ntshiab kua ua kua polyaluminum tshuaj polyaluminum yog nyob hauv thaj tsam ntawm 40% ~ 60%, nws yog lub teeb daj pob tshab. Thaum lub alkalinity muaj ntau dua 60%, nws maj mam ua ib cov kua tsis muaj kob.

2, Thaum lub alkalinity yog tsawg dua 30%, khoom polyaluminum tshuaj chloride yog lub lens.

3, Thaum lub alkalinity nyob hauv thaj tsam ntawm 30% ~ 60%, nws yog cov khoom siv colloidal.

4, Thaum lub alkalinity loj dua 60%, nws maj tiav niam txiv lossis resin.Solid polyaluminum chloride ua los ntawm bauxite lossis av nplaum ntxhia lossis xim av.

22-24% cov ntsiab lus:Nruas kom yooj yim txheej txheem kev tsim khoom, tsis muaj phaj thiab ncej lim, cov khoom lag luam tsis muaj dej ntawm cov khoom lag luam, feem ntau yog siv rau kev lag luam khib nyiab.

26% cov ntsiab lus:Nruas kom ua kom tiav cov txheej txheem ua kom qhuav, tsis muaj phaj thiab cov khoom siv hauv ntiaj teb, tus nqi yog ib nyuag qib, feem ntau yog siv hauv kev kho kom muaj kev kho dej khib nyiab.

28% cov ntsiab lus:Qhov no muaj ob yam txheej txheem ntawm cov nruas ua kom qhuav thiab ua kua los ntawm thawj ob lub qis, tuaj yeem siv rau cov khoom lag luam qib siab, ua kua rau rau cov dej tsis huv thiab coj mus rhaub dej cog etricement.

30% cov ntsiab lus:Muaj ob hom nruas kom qhuav thiab ua kom qhuav, niam kua los ntawm cov phaj ncej roj, tsuas yog siv rau hauv cov dej cog thiab qis turidity ntawm kev kho dej hauv tsev.

32% cov ntsiab lus:Qhov no yog tsim los ntawm cov tshuaj tsuag ziab, yog txawv ntawm lwm cov khoom lag luam, feem ntau yog cov tshuaj lom neeg tsis yog-ferrous polyaluminum chloride, tshuaj pleev ib ce tsim khoom, yog rau cov zaub mov qib.

Polyacrylamide:hu ua Pa m, feem ntau yog hu ua flocculant lossis coagulant

Lub hauv paus ntsiab lus:Pam molecular saw thiab dispersed theem dhau los ntawm ntau yam ntawm ntau yam kev siv zog, kev coj noj coj ua, sib sau ua ke, yog li txhim kho lub luag haujlwm.

Performance:Pam yog hmoov dawb, soluble hauv dej, yuav luag Incegent cov khoom siv egents, acetone thiab lwm yam kev lom zem, kev lom zem ntxiv nrog kev nce ntawm ionic degree.

Pam raws li nws cov yam ntxwv ntawm cov pab pawg sib cais tau muab faib ua anionic polyacrylamide, cationic polyacrylamide thiab ionic polyacrylamide. Ionic polyacrylamide.

Cationic Pam:Ua kom qis qis qis los ntawm cov qauv biochemical

Anionic Pam:Dej phwj thiab sludge nrog kev them nqi zoo, xws li cov nroj tsuag steel, metallurgy, thee ntxuav, thee kev ntxuav thiab lwm yam dej phwj tuaj thiab lwm yam dej phwj tuaj

Nonionic pam:rau cationic thiab anionic muaj cov nyhuv zoo, tab sis chav tsev yog kim heev, feem ntau tsis siv

Ob qho tib si ntxiv rau siv cov lus qhia

What is flocculation?After adding coagulant to the raw water, fully mixing with the water body, most of the colloid impurities in the water lose stability, and the unstable colloid particles collide and condense with each other in the flocculation pool, and then form the floc that can be removed by precipitation method.

Cov yam ntxwv ntawm flocculation

Cov txheej txheem ntawm floc kev loj hlob yog txheej txheem ntawm kev sib cuag thiab kev sib tsoo ntawm cov me me.

Cov txiaj ntsig ntawm flocculation zoo nyob ntawm ob yam hauv qab no:

1 Lub peev xwm ntawm cov polymer comped los ntawm coagulant hydrolysis los tsim adsorption tus choj, uas yog txiav txim siab los ntawm cov khoom ntawm Coagulants

2 Qhov tshwm sim ntawm kev sib tsoo me me thiab yuav ua li cas los tswj hwm lawv rau kev ua kom muaj zog thiab muaj peev xwm ua kom muaj zog ntxiv, ntxiv rau cov kev sib tsoo hauv flocculation thiab loj hlob sai sai ntawm flocculation, lawv yuav raug rhuav tshem. Muaj ob Teeb meem: 1 floc kev loj hlob sai heev nws lub zog yog tsis muaj zog, yog li cov txheej txheem floccity tseem yuav ua rau cov dej floc tshwj xeeb, qee qhov kev tawm tsam Tsis yog zoo meej me me cov tshuaj tiv thaiv kev mob, cov ntu me me no tsis tuaj yeem tsuas yog rau lub tank tank kom tau txais, nws tseem nyuaj rau khaws cia rau lub lim.)

Ntxiv Yuav Tsum Tau

In the early stage of the reaction of adding coagulant, it is necessary to increase the chance of contact with sewage as much as possible, increase the mixing or flow rate.Depending on the collision of water flow and folding plate and the flow of water between folding plate to increase the speed, so that the water particles collision opportunity increases, so that the floc condensation.And to the late reaction, in order to reduce the speed gradient, can get better flocculation, precipitation effect.

Ntxiv Khoom Siv:Cov ntim yeeb tshuaj yeeb, tshuaj tso tshuaj tu tshuaj, Dosing Stirrer, Dosing twj tso kua mis thiab metering cov khoom siv. Nruab nrog kev siv cov hau kev

PAC, PAM discensing concentration (coj tawm ntawm lub hnab ntim tshuaj thiab ntxiv rau cov khoom siv ua kom tiav raws li kev ua kom zoo nkauj, yog txwv, yuav tsum tau do tag nrho cov khoom nruab nrab ntawm cov pa roj teeb uas muaj 10% = 42 litres / teev, tuaj yeem ua tiav cov kev kho dej phwj tuaj zoo focculation. PAC, PAM DEJ DEJ DOSAGE (yaj hauv cov dej uas muaj txiaj ntsig, yog ib qho kev hloov kho txhua hnub, yog li hloov pauv ntawm cov dej phwj. Cov koob tshuaj ntau dua li 50ppm, Pam Dosage concentration, ces txhua hnub pac tau xav tau raws li kev sim cov dej zoo. Laij cov teev tus nqi hauv Dosing twj tso dej ntws

Tom qab ntxiv tus neeg sawv cev rau cov dej phwj tuaj lossis sludge, nws yuav tsum muaj kev sib xyaw zoo. Lub sijhawm sib xyaw yog feem ntau 10-30 vib nas this, feem ntau tsis muaj ntau tshaj 2 feeb. Cov tshuaj tshwj xeeb ntawm tus neeg sawv cev thiab cov khoom siv sib xyaw (PPM) muaj kev sib raug zoo ntxiv (PPM) thiab cov khoom siv ntws tawm (T / H) thiab kev teeb tsa ntawm kev daws teeb meem (PPM2 npaj kev xav tau), tuaj yeem suav rau ntawm Dosing twj Floughet zaub muaj txiaj ntsig (LPM

Nco tseg: PPM yog ib lab;
