01 Membrane puas
Cov tsos mob: kev tsim dej dej ntau ntxiv, kev poob qis qis tus nqi, thiab kev ua kom muaj zog ntau ntxiv.
Qhov tshwm sim: kev ua qias tuaj ntawm cov dej inlet, rupture ntawm frp plhaub raws cov kev taw qhia Axial, thiab kev tawm tsam ntawm cov dej inlet daim phiaj. Tom qab daim nyias nyias muaj dissected, npuas thiab stratification tshwm rau ntawm daim nyias nyias.
Cov teeb meem: kev ua haujlwm tsis raug, ua rau rov qab siab, xws li tsis nco qab qhib lub qhov dej ntau lawm qhib lub valve tom qab tu; Ntau dhau dej inlet siab sib txawv; Hlau oxidants lossis lwm yam kev cuam tshuam hauv cov dej pub mis ua rau hnav rau lub ntsej muag.
Kev daws: Ua haujlwm raws li cov kev cai, nruj me ntsis tiv thaiv rov qab siab; txhim kho pretricatment, huv si hauv lub sijhawm, tiv thaiv kev sib txawv ntau dhau; Hloov cov ntsiab lus.
02 microbial me me
Cov tsos mob: Cov dej tsim dej tsawg dua, kev poob qis qis tus nqi, thiab ua kom muaj qhov sib txawv ua kom tau ntau dua.
Qhov tshwm sim: cov kab mob me me microorganisms yug menyuam, thiab tom qab lub plhaub mis tau muab tso rau sab hauv daim tawv nqaij, thiab cov dej hauv qab ndig channel, nrog tus ntxhiab tsw phem.
Cause: Tus neeg muaj peev xwm nplua nuj yog nplua nuj nyob rau hauv cov as-ham, xws li HIGHT toc thiab cod; Tus dej tsis muaj cov kab mob sib xws yog qhov tsis muaj kom tsis muaj menyuam lossis tsis muaj tsis muaj ncua; Cov nplai inhibitor tau dhau -}} Lub thawv tshuaj yog qhov tsis muaj paug; Cov dej ntws tom qab kaw lawm tsis tau raws sijhawm, ua rau cov kab mob me me tsis huv; Ntau dhau ntawm kev txo tus neeg sawv cev ua rau txoj kev loj hlob ntawm cov kab mob anaerobic.
Kev daws: Teeb cov khoom tsis muaj menyuam lossis kho cov tshuaj kom tiv thaiv cov microbial paug ntawm cov dej nyoos; Kho cov tshuaj ntawm tus neeg sawv cev txo qis; Siv tsis - oxidizing bactericides, xws li dbnpa kom muaj kev cuam tshuam kom tsis muaj menyuam kom tsis muaj menyuam; disinfect the entire system, including pretreatment and membrane, to prevent re-contamination; Siv ph =12-13} muaj zog} muaj zog alkali kom tu thiab rov qab, thiab n}} sds lossis na4edta tuaj yeem siv rau kev ntxuav.
03 sediment particle purution
Cov tsos mob: Kev tsim dej dej yuav txo qis, tus nqi desalination txo qis, siab qhov sib txawv ntxiv, thiab inlet siab.
Qhov tshwm sim: kev ua kom pom cov nplais ua rau ntawm qhov inlet kawg ntawm thawj ob peb membrane cov ntsiab lus hauv thawj ntu.
Cause: Raw dej yog kuab paug; Pretricatment tsis txaus; Coagulant yog siv tsis raug. Qhov ntau npaum li cas ntawm pretreatment tsis tsim nyog, thiab ntau dhau ntawm FLOCCCULANT ua rau flocculation theem ob; Flocculant yog incomple haum nrog cov dej zoo; Qhov sib raug zoo ntawm cov neeg saib xyuas dej yog muaj teeb meem.
Kev daws: Txheeb xyuas cov txheej txheem ua haujlwm thiab kho cov haujlwm ua haujlwm; Kho cov hom thiab noj tshuaj ntawm coagulant; Ntxiv cov kab mob tshwj xeeb; Ntxuav daim nyias nyias.
04 Membrane Oxidation
Cov tsos mob: Cov dej tsim kev tsim tawm dej ntau ntxiv, qhov kev cia siab tsawg, thiab siab sib txawv tseem tiaj.
Qhov tshwm sim: Tom qab kev sim ua kom tsis txaus siab, cov kev sim sim hauv Fujiwara kev sim hloov pauv liab, thiab chlorine lossis bromine hais los ntawm atomic spectrochemical tsom xam (esca).
Cause: Ntau dhau ntawm pretreatment oxidizing txaws; Ua tsis tiav ntawm kev txo tus neeg sawv cev lossis tsis txaus ntxiv.
Kev daws: Kev ntsuas kev cais tawm; Kev tswj nruj ntawm tus nqi tsis muaj txiaj ntsig lossis tus nqi ep; Lub ntsiab lus me me yog irreversibly puas thiab nyuaj kho, yog li daim nyias nyias muaj peev xwm hloov tau.
