FAQ

A: Peb muab ntau yam tshuaj kho dej rau hauv nroog, kev lag luam, kev lag luam, thiab lwm yam kev kho dej. Peb cov khoom tseem ceeb series muaj xws li:
Aluminium Sulfate (Alum)
Ammonium hmoov
Polyaluminium Chloride (PAC)
Polyacrylamide (PAM)
Ferrous Sulfate
Cov khoom sib txawv yog tsim rau cov txheej txheem kev kho mob sib txawv thiab cov dej tsis zoo. Cov khoom qib, specification, concentration, thiab lub cev daim ntawv kuj txawv raws li lub hom phiaj daim ntawv thov.

A: Cov tshuaj zoo yog nyob ntawm koj cov dej zoo, lub hom phiaj kev kho mob, txheej txheem tsim, thiab kev ua haujlwm. Piv txwv li, txhuas sulfate thiab PAC feem ntau yog siv los ua coagulants, thaum sib txawv qib ntawm polyacrylamide tuaj yeem siv los ua flocculants hauv cov khoom sib cais - cov txheej txheem ua kua. Ferrous sulfate tuaj yeem siv rau hauv kev coagulation thiab kev kho dej khib nyiab. Rau qhov kev pom zoo ntau dua, peb xav muab koj hom dej, lub hom phiaj kho, txheej txheem kev kho tam sim no, thiab cov ntaub ntawv muaj dej zoo. Peb pab pawg kws tshaj lij tuaj yeem pab txheeb xyuas cov khoom tsim nyog thiab cov lus qhia tshwj xeeb.

A: Yog. Dej zoo yog ib qho tseem ceeb tshaj plaws thaum xaiv cov tshuaj kho mob. Yog tias muaj, thov muab cov kev txwv xws li turbidity, pH, COD, BOD, tshem tawm cov khib nyiab, hardness, phosphorus, hlau, lossis lwm yam ntsuas. Cov ntaub ntawv hais txog cov txheej txheem kho thiab cov tshuaj siv tam sim no kuj tseem pab tau. Raws li cov ntaub ntawv muaj, peb tuaj yeem sib tham txog kev xaiv cov khoom, cov lus pom zoo, kev kuaj ntau npaum li cas, thiab daim ntawv thov.

A: Aluminium sulfate yog siv dav hauv inorganic coagulant. Thaum ntxiv rau cov dej nyob rau hauv qhov tsim nyog, cov tsiaj txhu tsim tawm thaum lub sij hawm hydrolysis tuaj yeem pab tshem tawm cov khoom tsis zoo thiab txhawb kev coagulation thiab floc tsim. Nws tuaj yeem siv rau hauv kev kho dej haus, kev kho dej khib nyiab, thiab lwm yam kev siv uas yuav tsum tau coagulation. Qhov kev noj kom tsim nyog yog nyob ntawm dej zoo, pH, kub, turbidity, tshem tawm cov khib nyiab, thiab lwm yam txheej txheem txheej txheem. Kev sim lub thawv yog pom zoo ua ntej txiav txim siab qhov kev ua haujlwm zaum kawg.

A: Ob leeg txhuas sulfate thiab PAC tuaj yeem siv los ua coagulants, tab sis lawv cov yam ntxwv tshuaj thiab kev kho mob sib txawv. Qhov kev xaiv zoo dua yog nyob ntawm qhov tshwj xeeb ntawm cov dej zoo thiab cov txheej txheem kev kho mob ntau dua li tsuas yog xaiv ib yam khoom thoob ntiaj teb. Cov yam tseem ceeb uas yuav tsum tau xav txog suav nrog cov yam ntxwv ntawm cov dej nyoos, pH qhov yuav tsum tau muaj, turbidity thiab tshem tawm cov khib nyiab, cov khoom organic, cov yam ntxwv floc xav tau, sludge ntau lawm, cov khoom siv uas twb muaj lawm, thiab tag nrho cov nqi kho mob. Rau ib txoj haujlwm tshiab, kev sim ntsuas lub thawv tuaj yeem pab sib piv cov coagulants sib txawv hauv cov dej tib yam.

A: Qhov sib txawv tseem ceeb yog lawv cov yam ntxwv ionic thiab kev cuam tshuam nrog cov khoom hauv cov txheej txheem kho. Anionic PAM nqa cov pab pawg ua haujlwm tsis zoo thiab feem ntau yog siv rau hauv cov ntawv thov uas adsorption thiab bridging nrog cov khoom muaj txiaj ntsig zoo lossis hlau hydroxide flocs xav tau. Cationic PAM nqa cov pab pawg ua haujlwm tau zoo thiab yog siv dav hauv cov dej txias thiab cov khoom sib cais - kua. Noionic PAM muaj tus cwj pwm ionic tsawg thiab tej zaum yuav raug xaiv rau cov dej chemistry qhov twg ionic polymers tsis haum. Qhov kev xaiv zaum kawg yuav tsum txiav txim siab los ntawm kev xeem daim ntawv thov.

A: Ob leeg tuaj yeem koom nrog cov txheej txheem coagulation, tab sis lawv yog raws li cov hlau ions sib txawv thiab yog li coj txawv txawv hauv kev kho dej. Aluminium sulfate yog ib qho txhuas-raws li coagulant, thaum ferrous sulfate yog hlau-raws li kev kho tshuaj. Qhov kev xaiv tsim nyog yog nyob ntawm lub hom phiaj muaj kuab paug, cov yam ntxwv ntawm cov dej nyoos, pH, oxidation tej yam kev mob, sludge zog, thiab kev kho cov dej hauv qab. Rau daim ntawv thov tshiab, kev sib piv lub thawv tuaj yeem pab txiav txim siab seb qhov kev kho mob twg yog qhov tsim nyog dua.

A: Kev xaiv PAM yuav tsum xav txog hom ionic, qhov hnyav molecular, qib ntawm hydrolysis los yog nqi them ceev, dej chemistry, khoom concentration, sludge yam ntxwv, pH, khoom kho mob, thiab yuav tsum tau daws los yog dewatering kev ua tau zoo. Rau sludge dewatering daim ntaub ntawv, cov khoom zoo tshaj plaws tsis tuaj yeem xaiv qhov kev ntseeg siab ntawm cov dej khib nyiab ib leeg. Kev sim kuaj nrog cov sludge tiag tiag yog pom zoo.

A: Yog, ntau npaum li cas tuaj yeem sib tham raws li cov khoom lag luam, dej zoo, lub hom phiaj kev kho mob, thiab cov txheej txheem txheej txheem. Txawm li cas los xij, tsis muaj universal ntau npaum li cas siv rau txhua qhov dej. Cov koob tshuaj tiag tiag yuav tsum tau txiav txim siab los ntawm kev kuaj sim lossis kev sim ntsuas thaum twg ua tau. Rau kev siv coagulation thiab flocculation, lub thawv kuaj yog ib txoj hauv kev zoo rau kev sib piv ntau npaum li cas thiab kev kho mob.

A: Cov qauv ntsuas tuaj yeem sib tham rau cov haujlwm uas xaiv cov khoom nyob ntawm qhov tseeb dej lossis cov yam ntxwv sludge. Piv txwv li, PAM xaiv rau sludge dewatering yog nyob ntawm cov khoom sludge, thaum xaiv coagulant tuaj yeem sib txawv nrog cov dej tsis huv. Yog xav tau kev sim, cov qauv yuav tsum tau ua thiab cov txheej txheem xeem yuav tsum tau pom zoo ua ntej.

A: Nyob ntawm cov khoom thiab kev txiav txim, peb tuaj yeem sib tham txog cov ntaub ntawv xws li Daim Ntawv Pov Thawj Kev Ntsuam Xyuas (COA), Daim Ntawv Pov Thawj Kev Nyab Xeeb (SDS), daim ntawv qhia cov khoom, Daim Ntawv Teev Npe (TDS), Daim Ntawv Pov Thawj Keeb Kwm, cov ntaub ntawv ntim khoom, tshuaj xyuas lossis cov ntaub ntawv xeem, thiab cov ntaub ntawv pov thawj siv tau nyob qhov twg. Cov ntaub ntawv qhia tseeb pob yuav tsum tau lees paub ua ntej xa khoom raws li cov khoom, lub teb chaws qhov chaw, thiab cov kev cai ntshuam.

A: Daim Ntawv Pov Thawj Kev Ntsuam Xyuas tuaj yeem muab tau raws li cov khoom lag luam pom zoo thiab kev txiav txim yuav tsum tau ua. COA tuaj yeem siv los ntawm tus neeg yuav khoom los txheeb xyuas qhov tseem ceeb tsis zoo tiv thaiv qhov kev pom zoo. Rau cov kev pabcuam tsis tu ncua, cov kev qhia tshwj xeeb thiab kev tshuaj xyuas yuav tsum tau pom zoo ua ntej los txhawb kev yuav khoom thiab kev tswj xyuas kom zoo.

A: Qee yam ntawm peb cov khoom tuaj yeem muab rau cov ntawv thov kev kho dej, suav nrog kev kho dej haus, nyob ntawm qib khoom, kev qhia tshwj xeeb, ntawv pov thawj, thiab qhov chaw nyob - kev ua lag luam. Rau cov dej haus cov dej num, cov tshuaj tshwj xeeb yuav tsum tau lees paub ua ntej yuav khoom, vim tias cov kev cai yuav tsum tau sib txawv ntawm cov teb chaws thiab cheeb tsam. Cov qauv xws li NSF / ANSI / CAN 60 hais txog kev noj qab haus huv yuav tsum tau siv rau cov tshuaj siv hauv kev kho dej haus, thiab txhuas sulfate thiab PAC yog cov tshuaj kho mob uas tau them los ntawm cov peev txheej. Cov neeg siv khoom yuav tsum paub meej txog cov kev cai hauv zos ua ntej muab qhov kev txiav txim.

A: Ntim nyob ntawm cov khoom, daim ntawv lub cev, kom muaj nuj nqis, txoj kev thauj mus los, thiab cov neeg siv khoom xav tau. Cov kev xav txog kev ntim khoom feem ntau suav nrog lub hnab loj, sab hauv liner, tiv thaiv ya raws, palletization, ntim ntim, thiab cov neeg siv khoom- cov ntawv tshwj xeeb. Ua ntej ua zaub mov xa tuaj, ntim cov ntsiab lus yuav tsum tau lees paub raws li cov khoom specifications thiab kev thauj mus los.

A: MOQ nyob ntawm cov khoom, specification, ntim txoj kev, thiab kev txiav txim yuav tsum tau. Rau qee cov khoom lag luam, loj dua - ntim xaj yuav tsim nyog rau cov khoom xa tuaj thoob ntiaj teb. Kev txiav txim me me lossis cov qauv coj mus kuaj kuj tuaj yeem sib tham nyob ntawm cov khoom. Thov qhia rau peb cov khoom koj xav tau, lub teb chaws lo lus uas peb, thiab kwv yees kom muaj nuj nqis kom peb thiaj li paub meej txog MOQ.

A: Kev cia khoom sib txawv ntawm cov tshuaj. Feem ntau, cov khoom yuav tsum tau muab khaws cia raws li SDS thiab cov khoom siv - cov kev cai tshwj xeeb tuav. Cov yam ntxwv xws li ya raws, cua sov, tshav ntuj ncaj qha, cov tshuaj tsis sib xws, qhov cua, thiab kev ntim khoom yuav tsum raug txiav txim siab. Rau hygroscopic lossis noo noo- cov khoom lag luam rhiab heev, kev tiv thaiv dej kom tsim nyog yog qhov tseem ceeb tshwj xeeb.

A: Cov qauv ntsuas tuaj yeem sib tham ua ntej kev txiav txim ntau, tshwj xeeb tshaj yog thaum cov tshuaj yuav siv rau hauv cov txheej txheem dej tshiab. Rau daim ntawv thov - cov khoom lag luam rhiab heev xws li PAM thiab coagulants, peb pom zoo kom kuaj cov khoom nrog dej los yog sludge thaum twg los tau. Cov qauv xav tau, ntau npaum li cas, txoj kev xa khoom, thiab cov nqi siv tau tuaj yeem lees paub raws li cov khoom lag luam thiab lub hom phiaj.

A: Txhawm rau pab peb teb tau zoo, thov muab cov ntaub ntawv hauv qab no kom ntau li ntau tau:
