Kev Sib Piv Kev Ntsuam Xyuas ntawm StandalonePAMvs.PAC+ PAM Cov Txheej Txheem Ua Ke hauv Kev Kho Dej Siv Hluav Taws Xob

Standalone PAM lossis PAC + PAM Kev Sib Txuas? Yuav Ua Li Cas Xaiv Ib Lub Tswv Yim Zoo Tshaj Plaws rau Kev Kho Dej Wastewater

Nyob rau hauv cov txheej txheem ntawm kev kho dej khib nyiab, ntau lub lag luam vam tias yuav daws tau cov teeb meem ntawm kev tshem tawm cov khib nyiab, sludge daws, thiab dej zoo stabilization los ntawm ib qho yooj yim tshuaj reagent. Txawm li cas los xij, muaj pes tsawg leeg ntawm cov pa phem hauv cov dej khib nyiab sib txawv sib txawv heev. Piv txwv li, tshem tawm cov khib nyiab, colloidal hais, emulsified roj, xim tshuaj, surfactants, thiab hlau ions tag nrho yuav cuam tshuam cov nyhuv flocculation.

Raws li tus kws tshaj lij kev kho dej tshuaj, ECOLINK TECHNOLOGY ntseeg tias tsis muaj "universal single solution" siv tau rau txhua qhov kev lag luam hauv kev kho dej khib nyiab. Raws li cov yam ntxwv ntawm cov dej khib nyiab thiab cov hom phiaj kev kho mob, cov lag luam feem ntau tuaj yeem xaiv ob txoj hauv kev tseem ceeb hauv qab no:

Siv polyacrylamide (PAM) ib leeg ua flocculant

Ib ob -txoj kev kho mob uas siv cov coagulant (PAC) ua ntej, ua ke nrog polyacrylamide (PAM)

Kev xaiv kom raug yog nyob ntawm qhov ruaj khov, cov dej tsis zoo, thiab cov phiaj xwm kho zaum kawg hauv cov dej khib nyiab, xws li kev txhim kho sedimentation efficiency, txhim khu kev ua tau zoo ntawm cov huab cua flotation (DAF), optimizing sludge dewatering kev ua tau zoo, los yog txhim kho kev ua haujlwm ruaj khov.

Hauv kev siv cov dej khib nyiab pov tseg, polyacrylamide (PAM) feem ntau ua lub luag haujlwm flocculating, thaum coagulant (PAC) feem ntau yog siv los rhuav tshem cov qauv colloidal ruaj khov, ua kom cov khoom zoo tsim micro-flocs uas nyob yooj yim dua. Thaum sib xyaw ua ke, PAC + PAM cov txheej txheem kho dej ruaj khov tuaj yeem tsim tau.

1. Txoj Cai Ua Haujlwm ntawm Polyacrylamide (PAM) hauv kev kho dej khib nyiab

Polyacrylamide (PAM) yog ib qho siab -molecular polymer dav siv nyob rau hauv industrial wastewater kho, sludge dewatering, mine tailings kev kho mob, thiab papermaking wastewater kho mob.

Lub luag haujlwm tseem ceeb ntawm kev ua ntawm PAM yog txhawm rau txuas cov khoom raug tshem tawm hauv dej los ntawm Polymer Bridging ntawm siab- cov saw hlau molecular, ua rau lawv tsim cov flocs loj thiab nruj, yog li txhim kho:

Qhov no yuav txo tau:

Tshuaj khib nyiab;

Tus nqi khiav lag luam nce;

Risk ntawm effluent fluctuation.

14. ECOLINK TECHNOLOGY muab kev kho dej khib nyiab muaj tshuaj thiab cov kev daws teeb meem

Raws li tus kws tshaj lij cov khoom lag luam kho dej, ECOLINK TECHNOLOGY tsis tsuas yog muab siab tshaj -zoo polyacrylamide (PAM), tab sis kuj muab:

Poly Aluminium Chloride (PAC);

Anionic Polyacrylamide (APAM);

Cationic Polyacrylamide (CPAM);

Nonionic Polyacrylamide (NPAM);

Cov khoom siv kho dej khib nyiab muaj;

Sludge dewatering daws.

Rau ntau hom kev lag luam khib nyiab, raws li:

Kev lag luam dej khib nyiab;

pH ntau yam;

turbidity;

Khoom hnyav;

Cov cuab yeej sib cais;

Peb pab cov neeg siv khoom xaiv cov qauv tshuaj tsim nyog.

Piv txwv li:

Sedimentation tank systems;

Dissolved Air Flotation (DAF) cov khoom siv;

Siv lim xovxwm;

Cov khoom siv centrifugal dewatering;

Phaj thiab ncej lim presses;

Txhua yam yuav tsum ua kom sib txawv ntawm PAM cov khoom lag luam thiab cov tswv yim siv tshuaj.

ECOLINK TECHNOLOGY hais kom muab cov kev daws teeb meem rau kev kho dej los ntawm kev kho cov teebmeem tiag tiag, tsis yog kev pom zoo ib qho "universal model".

Yog tias koj tab tom nrhiav rau cov txheej txheem kev kho dej khib nyiab nrog kev ua haujlwm zoo dua PAC thiab PAM, lossis xav ua kom zoo dua cov txheej txheem ntawm PAM hauv kev kho dej khib nyiab, txais tos hu rau peb. Peb tuaj yeem muab cov lus qhia tshwj xeeb raws li koj cov qauv dej thiab cov txheej txheem txheej txheem.

15. Cov lus nug nquag nug (FAQ)

Q1: PAM puas tuaj yeem siv ib leeg hauv kev kho dej khib nyiab?

Yog lawm.

Yog tias cov khoom raug tshem tawm hauv cov dej khib nyiab sib sau ua ke yooj yim thiab cov ntsiab lus colloidal tsawg, siv PAM ib leeg tuaj yeem ua tiav cov txiaj ntsig zoo flocculation. Txawm li cas los xij, rau oily, siab -xim, thiab siab - cov dej khib nyiab colloidal, PAC + PAM ua ke feem ntau pom zoo.

Q2: Vim li cas PAC thiab PAM yuav tsum tau siv ua ke?

PAC feem ntau yog lub luag haujlwm rau colloidal destabilization, them nyiaj nruab nrab, thiab micro-floc tsim.

PAM yog lub luag haujlwm tseem ceeb rau kev loj hlob ntawm floc, ua kom nrawm nrawm, thiab txhim kho kev ua haujlwm dewatering.

Ob leeg muaj cov haujlwm sib txawv, yog li kev siv ua ke tuaj yeem txhim kho kev ruaj ntseg.

Q3: Dab tsi yog qhov ntau npaum li cas ntawm PAM hauv kev kho dej khib nyiab?

Nws txawv heev ntawm cov dej khib nyiab sib txawv. Raws li kev siv tswv yim:

Kev piav qhia kev kho ntau yam yog kwv yees li0.2-5.0 mg / L;

Electroplating wastewater settling test yog kwv yees li0.5-3.0 mg / L;

Textile wastewater kuaj ntau yam yog kwv yees li0.5-2.0 mg / L.

Cov koob tshuaj zaum kawg yuav tsum tau txiav txim siab los ntawm kev xeem lub thawv.

Q4: Yuav ua li cas xaiv cov kev kho dej khib nyiab flocculants tsim nyog?

Kev txiav txim siab dav dav yog xav tau rau cov pa phem, kev lag luam dej khib nyiab, pH tej yam kev mob, cov khoom muaj zog, thiab cov khoom siv kho mob hauv qab. ECOLINK TECHNOLOGY pom zoo kom txiav txim siab qhov kev pom zoo los ntawm ntawm -qhov chaw kuaj dej.
