Kev Tshawb Fawb Txog Kev Ua Haujlwm Ntawm Kev Ua Kom Zoo Ntawm Cov Khoom Siv Thiab Organic Micro Pollutants Los Ntawm Lim Element Ntawm Cov Dej Purifier Hauv Tsev

Nrog rau kev txhim kho ntawm kev ua neej nyob, kev noj qab haus huv thiab kev nyab xeeb ntawm cov dej haus hauv tsev tau muaj kev txhawj xeeb ntau hauv xyoo tas los no. Cov txheej txheem kev kho cov pa uas tau txais los ntawm Waterworks hauv peb lub teb chaws tsis tuaj yeem ua tau raws li qhov xav tau ntawm cov neeg siv khoom siv rau kev haus dej ncaj qha, thiab cov dej kais dej yog ib qho yooj yim ua rau muaj kuab paug thib ob tom qab raug thauj los ntawm qee cov kav dej hauv nroog hauv kev puas tsuaj rau lub sijhawm ntev. Feem ntau ntawm cov neeg nyob hauv peb lub teb chaws siv thoob cov dej lim dej rau haus, tab sis cov thoob dej tsis yooj yim siv, yog li cov dej lim dej hauv tsev muaj kev txhawj xeeb ntau dua. Lub tshuab lim dej hauv tsev yog tsim los ntawm cov lim dej ntawm cov khoom sib txawv thiab cov txheej txheem, thiab txhua lub lim dej muaj nws cov haujlwm tshwj xeeb ntawm kev tshem tawm cov pa phem. Tam sim no, tsis muaj kev tshawb fawb me me ntawm kev ua kom huv ntawm monomer lim caij. Daim ntawv no txheeb xyuas qhov teeb meem nrhiav pom los ntawm kev kawm txog cov qauv kev lag luam dej lim dej uas twb muaj lawm hauv tsev thiab txawv teb chaws. Nyob rau hauv daim ntawv no, lub monomer purification ntawm ntau PPC lim, activated carbon lim thiab rov qab osmosis lim nyob rau hauv tsev neeg cov dej purifier tau kawm. Kev ua kom huv huv ntawm cov lim tau pom los ntawm kev hloov chaw ua haujlwm thiab qhov muaj zog ntawm cov lim dej. Peb hom 5 μ m PPC lim cov ntsiab lus nrog qhov ceev ntawm a, B thiab C tau siv; cov txheej txheem kev daws teeb meem nrog turbidity ntawm 15ntu tau npaj thiab dhau los ntawm peb hom PPC lim ntsiab nrog siab ntawm 0.3MPa. Lub txee particle tau siv los soj ntsuam cov qauv micro ntawm PP paj rwb lim. Nws tau pom tias cov khoom uas muaj qhov me me tsawg dua 5 μ m suav nrog 90.4%, 83.58% thiab 81.49% feem. Qhov nruab nrab particle loj ntawm lim a yog qhov tsawg tshaj plaws, ua raws li lim B thiab lim C. Nyob rau hauv cov nqe lus ntawm kev hloov ntawm purification efficiency nrog tus nqi ntawm cov dej purified, thawj purification efficiency ntawm lim a yog siab tshaj, thiab nws thawj purification efficiency. nce mus txog 94%, ua raws li cov lim B, uas nce mus txog 92%, thiab cov lim C yog qhov qis tshaj. Nrog rau qhov nce ntawm cov dej huv huv, kev ua kom huv huv ntawm peb hom PP lim cov ntsiab lus pom qhov kev poob qis, thiab tus nqi qis kuj txawv. Lub attenuation ntawm purification efficiency ntawm lim lub caij a thiab lim B yog qeeb dua li lub lim dej C, thiab lim caij C mus txog lub xeev scrapped ua ntej. Nyob rau tib lub sijhawm, kev sib raug zoo ntawm tus nqi ntws thiab kev ua kom huv huv tau pom, uas yog qhov pab tau rau cov neeg siv khoom xaiv PP lim cov khoom uas zoo dua qub thiab hloov lub sijhawm. Los ntawm kev kho lub twj tso kua mis lub twj tso kua mis ntawm cov cuab yeej thiab tswj tus nqi ntws ntawm 25ml / s-55ml / s, qhov kev sim ntawm kev hloov pauv tus nqi ntws ntawm cov tshuab lim dej lim dej qhia tau hais tias cov dej lim dej huv ntawm cov lim dej lim dej lim dej tau tswj xyuas. ntawm li 35ml / s, uas tuaj yeem ua kom muaj kev ua kom huv huv thiab ua kom dej nrawm; Qhov kev sim ntawm kev hloov cov concentration ntawm cov kuab paug muaj kuab paug nyob rau hauv lub activated carbon lim caij qhia tau hais tias thaum lub influent concentration yog tsawg, lub purification efficiency ntawm activated carbon lim caij yuav guaranteed, lub purification efficiency ntawm peb hom activated carbon lim ntsiab. rau cov organic teeb meem yog ntau tshaj 90%, nrog rau kev nce ntawm influent concentration, lub purification efficiency qhia ib tug downward qauv; Nrog rau qhov nce ntawm cov dej huv huv, kev ua kom huv huv ntawm peb hom activated carbon lim cov ntsiab lus qhia tau hais tias kev poob qis, thiab kev ua kom huv ntawm peb hom activated carbon lim cov ntsiab lus txo mus rau 33%, 50% thiab 45% raws li tom qab cov dej tas li. mov ntawm 3.6m3, Tom qab ntawd lub durability ntawm peb hom activated carbon lim ntsiab tau soj ntsuam. Thaum kawg, qhov kev sim sib txawv ntawm qhov rov qab osmosis lim caij hauv lub tshuab lim dej hauv tsev tau ua tiav. Los ntawm kev hloov cov dej inlet kub, inlet dej siab, inlet concentration thiab raw cov dej rov qab tus nqi ntawm lub rov qab osmosis lim caij, nws tau pom tias cov dej inlet kub yuav hloov tau cov dej purified flow rate ntawm rov qab osmosis lim caij, qhov kub thiab txias. tuaj yeem nce mus rau qib siab dua, thiab cov dej ua kom nrawm dua, uas piav qhia tias yog vim li cas cov dej ua kom ceev ntawm tsev neeg rov qab osmosis lim caij qeeb qeeb hauv lub caij ntuj no dua li lub caij ntuj sov, Nws tau pom tias qhov dej kub ntawm tsev neeg thim rov qab. osmosis dej purifier yuav tsum tau khaws cia ntawm 15-30 ℃. Cov tshuaj lead ion concentrations yog 0.2 mg / L, 0.3 mg / L, 0.4 mg / L, 0.5 mg / L, 1 mg / L, 1.5 mg / L thiab 2 mg / L raws li. Los ntawm qhov rov qab osmosis lim caij, nws tau pom tias cov dej purification ceev thiab purification efficiency tau txo qis. Los ntawm kev hloov lub zog siab los tshawb xyuas cov nyhuv purification ntawm lub rov qab osmosis lim caij, nws pom tau tias qhov nce ntawm lub zog siab yuav ua rau cov net siab ntawm rov qab osmosis membrane, thiab cov dej tawm los kuj yuav nce ntxiv. Feem ntau hais lus, lub zog siab ntawm qhov rov qab osmosis lim caij ntawm lub tshuab lim dej hauv tsev yog qhov zoo tshaj plaws kom tswj tau ntawm 0.4-0.5mpa. Los ntawm qhov kev sim no, peb cia siab tias yuav txhawb txoj kev loj hlob ntawm kev lag luam hauv tsev dej purifier.
