Daim ntawv thov ntawm PAC hauv kev lag luam ntawv

Polyaluminum Chloride (PAC) yog ib yam tshuaj tseem ceeb hauv kev lag luam ua ntawv, ua lub luag haujlwm tseem ceeb hauv ntau theem ntawm cov txheej txheem ua ntawv. PAC yog ib qho coagulant feem ntau siv los txhim kho kev khaws cia cov khoom me me, cov khoom sau, thiab cov fibers, yog li txhim kho kev ua haujlwm zoo thiab zoo ntawm kev tsim ntawv.

Kev coagulation thiab flocculation

Lub luag haujlwm tseem ceeb ntawm PAC hauv kev ua ntawv yog nws cov khoom coagulation thiab flocculation. Thaum lub sijhawm ua ntawv, dej sib xyaw nrog cov cellulose fibers los ua cov slurry. Cov slurry no muaj cov khoom me me thiab cov organic uas yaj uas yuav tsum tau tshem tawm kom tsim tau cov ntawv zoo. PAC, thaum ntxiv rau hauv cov slurry, ua rau cov nqi tsis zoo ntawm cov khoom raug tshem tawm, ua rau lawv sib sau ua ke rau hauv cov aggregates loj dua lossis flocs. Cov txheej txheem no pab tau zoo heev rau kev tshem tawm cov khoom me me no thaum lub sijhawm ua kua dej, ua rau dej ntshiab dua thiab txhim kho cov fiber khaws cia.

Kev Khaws Cia thiab Kev Nqus Dej Zoo Dua

Kev khaws cov fibers thiab cov khoom sau yog qhov tseem ceeb hauv kev ua ntawv vim nws cuam tshuam ncaj qha rau daim ntawv lub zog, kev ntxhib los mos, thiab qhov zoo tag nrho. PAC txhim kho kev khaws cia ntawm cov ntaub ntawv no los ntawm kev tsim cov flocs loj dua uas tuaj yeem khaws cia yooj yim ntawm cov hlau tshuab ntawv. Qhov no tsis yog tsuas yog ua kom lub zog thiab zoo ntawm daim ntawv xwb tab sis kuj txo qhov ntau ntawm cov khoom siv raw poob, ua rau kev txuag nqi. Ntxiv mus, kev ntws dej zoo dua los ntawm PAC txo cov dej hauv daim ntawv, yog li txo cov zog uas xav tau rau kev ziab thiab txhim kho kev ua haujlwm tag nrho ntawm cov txheej txheem ua ntawv.

Kev Txhim Kho Qhov Zoo ntawm Daim Ntawv

Kev siv PAC hauv kev ua ntawv pab txhawb rau kev txhim kho qhov zoo ntawm daim ntawv. Los ntawm kev txhim kho kev khaws cia ntawm cov nplua thiab cov khoom sau, PAC pab tsim cov ntawv nrog kev tsim zoo dua, kev sib npaug, thiab cov khoom nto. Qhov no ua rau kev luam ntawv zoo dua, kev du, thiab qhov zoo li ntawm daim ntawv, ua rau nws tsim nyog dua rau kev luam ntawv zoo thiab kev ntim khoom.

Kev txo qis ntawm BOD thiab COD hauv kev kho dej khib nyiab los ntawm kev ua ntawv

Kev Xav Tau Oxygen Biochemical (BOD) thiab Kev Xav Tau Oxygen Chemical (COD) yog kev ntsuas ntawm qhov ntau ntawm cov organic teeb meem uas muaj nyob rau hauv cov dej khib nyiab uas tsim los ntawm cov txheej txheem ua ntawv. Cov theem siab ntawm BOD thiab COD qhia txog qib siab ntawm kev ua qias tuaj, uas tuaj yeem ua rau puas tsuaj rau ib puag ncig. PAC ua kom txo qis BOD thiab COD los ntawm kev sib sau ua ke thiab tshem tawm cov organic contaminations ntawm cov dej khib nyiab. Qhov no tsis yog tsuas yog pab ua raws li cov cai ib puag ncig xwb tab sis kuj txo cov nqi kho mob uas cuam tshuam nrog kev tswj hwm dej khib nyiab.

Hauv kev xaus lus, polyaluminum chloride yog ib qho tseem ceeb hauv kev lag luam ua ntawv, muab ntau yam txiaj ntsig uas txhim kho kev ua haujlwm ntawm cov txheej txheem ua ntawv thiab qhov zoo ntawm cov khoom kawg. Nws lub luag haujlwm hauv kev coagulation thiab flocculation, txhim kho kev khaws cia thiab kev ntws tawm, txo qis BOD thiab COD, thiab kev txhim kho tag nrho ntawm cov ntawv zoo ua rau nws yog ib qho tseem ceeb hauv kev ua ntawv niaj hnub.
