Rau cov neeg siv ntawm sodium hypochlorite generators, muaj tseeb kho ncaj qha cuam tshuam, tus nqi tswj, thiab ua raws li cov qauv dej. Hauv qab no yog cov kev ua tiav, cov qauv {{{{1} {{{2} -}) kom phim koj lub tshuab hluav taws xob kom phim rau koj cov kev xav tau tshwj xeeb.
Koob tshuaj noj kom zoo
Ua ntej kev txiav txim siab cov sodium hypochlorite generator koob, nws yog qhov tseem ceeb kom paub meej tias cov corrorine xav tau, uas tau txais txiaj ntsig ua qauv qauv xaiv. Tus Qauv Txheej Txheem yog:
Muaj Chlaline Xav Tau (G / H)=Cov dej ntim ntim (T / D) × Tag nrho cov chlorine cov phiaj xwm (Mg / L) ÷ 24 teev
NCO TSEG: Tam sim no tsis muaj chaw ua haujlwm hauv lub teb chaws tus qauv rau cov tshuaj chlorine ntau hla lub cev dej txawv txawv. Cov ntaub ntawv hauv qab no yog cov lus pov thawj hauv qab no yog cov lus pov thawj, thiab kev tshuaj dosing yuav tsum txiav txim siab txog ntawm -} qhov chaw ntsuas kom meej raws li kev ua raws thiab ua hauj lwm zoo.
Daim Ntawv Thov: Cov Khoom Siv Hauv Nroog
Muaj cov xwm txheej muaj feem xyuam
Cov chaw dej me me thiab nruab nrab rau cov nroj tsuag dej loj, raws li cov tshuaj hauv cov nroj tsuag zoo, uas xav tau cov tshuaj ntsuab hauv cog kom 0.3-2 mg / l.
(1) cov dej tsis huv
Cov dej saum npoo av (dej ntws, cov dej khov nab):
Tsim Dose=1}} - 2 mg / l
Vim li cas: saum npoo dej muaj ntau dua algae thiab cov organic teeb meem, xav tau cov tshuaj chlorine ntau dua rau cov oxidize impurities thiab ua tiav kev txhim kho kev txhim kho.
Cov av hauv av (Whs, Springs):
Tsim Dose=0.5} - 1 mg / l
Vim li cas: Avwater yog lim thiab nqus dej, tso cai rau cov tshuaj xhlorine qis kom tau raws li kev zam kev nyab xeeb tshaj plaws hauv chlorine.
(2) nruab nrab thiab cov nroj tsuag loj
Yuav tsum koom ua ke nrog peb -} Cov txheej txheem tua kab mob theem: Pre6 1} → post {2} → noj tshuaj chlorination.
Pre6 - phlorination: 1-1.5 mg / l
Thov ua ntej lub turimentation tank rau oxidation thiab algae inhibition.
Post - phlorination: 2-2.5 mg / l
Thov ua ntej siv tshuaj tua kab mob tank; Ua kom muaj ntau dua lossis sib npaug rau 30 feeb thaum lub sij hawm hu rau tag nrho cov pathogens.
Dosing chlorination: 0.5-1 mg / l
Saib xyuas ntau dua los yog sib npaug rau 0.05 mg / l seem ntawm cov tshuaj pua ntawm cov raj xa dej kom tiv thaiv kom tsis muaj kuab paug theem nrab.
Daim Ntawv Thov: Kev lim dej hauv tsev
Muaj cov xwm txheej muaj feem xyuam
Dej phwj dej kho cov nroj tsuag ntawm theem kev kho ntau yam. Cov koob tshuaj uas yuav tsum muaj nyob ntawm cov℃ntawm cov pa phem tshem tawm.
Tom qab Kev Kho Mob Koom Tes: 20-30 mg / l
Vim li cas: cov ntsiab lus siab ntawm cov organic teeb meem thiab cov khib nyiab tshem tawm xav tau muaj zog oxidation thiab kev siv tshuaj tua kab mob. *
Tom qab kev kho tsis tiav theem nrab: 10-15 mg / l
Vim li cas: muaj pes tsawg tus neeg muaj kuab paug qias kom yuav tsum muaj koob tshuaj lom zem rau ob qho kev khwv tau thiab kev lag luam. *
Tom qab ua tiav kev kho mob theem nrab: 5-10 mg / l
Yog vim li cas: qis dua lub cev thiab cov tawv tawv tso cai txo cov tshuaj chlorine thaum tseem sib tham tsawg dua lossis sib npaug ntawm 1000 CFU / L).
Daim Ntawv Thov: Ua luam dej Pas Dej Khab
Muaj cov xwm txheej muaj feem xyuam
Pej xeem thiab ntiav pas dej da, ua raws GB37488-2019 txoj kev nyiam huv si thiab txwv rau cov chaw pej xeem.
Residual chlorine yuav tsum:
Tswj 0.3-1.0 mg / l dawb chlorine hauv pas dej dej. Tseeb {{3} Kev saib xyuas lub sijhawm yog qhov tseem ceeb kom tiv thaiv kev txob khaus los ntawm cov chlorine ntau dhau.
Discpicction koob tshuaj tiv thaiv:
2 mg / l Dawb chlorine ua tiav tau tag nrho cov tshuaj tua kab mob (99.99% tshem tawm ntawm E. coli thiab fungi).
Dynamic hloov kho cov ntsiab cai:
Nce los ntawm 0.2-0.5 mg / u thaum siab- tsheb khiav (hnub so, hnub so).
Txo los ntawm 0.1-0.2 mg / u thaum tsawg - lub sijhawm tsheb los txo cov khib nyiab tsawg.
Daim Ntawv Thov Daim Ntawv Thov: Tsev Kho Mob Lim & Thermal Fais Fab Tsob Nroj Kev
Siv tau rau hauv tsev hauv tsev thiab kev kho mob, suav nrog kuaj thiab muaj chav dej lim dej.
Pom zoo xyaum:
Ua kev sim ib qho kev sim nrog 15-25 MG / L tshuaj, tom qab ntawd kho raws li "tag nrho cov coliforms tsawg dua lossis sib npaug nrog 500 CFU / DISCED tus qauv.
Nce koob tshuaj los ntawm 5-10 mg / u rau hom kab mob sib kis.
(2) thermal zog cog cov kab ncig
Siv rau kev ua kom txias cov dej tua kab, tiv thaiv algae kev loj hlob thiab xeb.
Tsawg - hardness dej (tsawg dua los yog sib luag rau 200 mg / l li caco₃): 3-5 mg / l
High-Hardness Water (>200 mg / l li caco₃): 5-8 mg / l
Lub hom phiaj seem seem: 0.5-1.0 mg / l
Ua kom muaj kev cuam tshuam tau zoo ntawm biofouling hauv kev sib ncig ntawm cov kab sib ncig.
Tseem Ceeb Tshaj Qhia
Txhua cov tshuaj cov ntaub ntawv muab tag nrho cov lus tshaj ntawd yog cov lus pov thawj. Rau kev ua tau zoo tshaj plaws:
Tsis tu ncua saib xyuas cov tshuaj nplaum uas siv cov tshuaj chlorine.
Kho cov kev siv tshuaj dynamically raws li kev kuaj ntsuas microbial tiag tiag (piv txwv li, nce los ntawm 10-20% yog tias fliforms ntau dua cov qauv).
Ib txwm ua raws li cov dej hauv zos thiab ib puag ncig cov cai, suav nrog cov dej phwj tuaj thiab cov qauv dej haus.
Yuav ua li cas kho Sodium Hypochlorite Generator koob raws li qhov tseeb
Kho cov koob tshuaj ntawm sodium hypochlorite generator tsis yog qhov hloov pauv cov hom phiaj zoo, thiab cov khoom sab nraud (piv txwv li cov neeg siv khoom). Hauv qab no yog qhov xwm txheej -}} kev hloov kho kev hloov kho, ua raws li cov qauv yav dhau los (GB3748-8) thiab cov ntaub ntawv txheeb xyuas.
Cov Ntsiab Cai Tseem Ceeb rau Dose Haum
Ua ntej tshaj, rov qab hais txog cov tseem ceeb ua kev laij zauv rau cov kev thov chlorine (mus rau lub nkoj kev hloov kho):
Yuav tsum muaj chlorine (g / h)=Cov dej ntim ntim (T / D) × kev sib zog chlorine concentration (mg / l) ÷ 24
Txhua qhov kev kho kom hloov mus ib puag ncig ntawm kev hloov kho "lub hom phiaj chlorine" (thaum ua kom txaus rau lub "Tsim kev hloov chaw"
1. Kho kom haum rau cov dej tshuaj (me me / nruab nrab- dej nroj tsuag loj)
Txheeb Xyuas Tseem Ceeb Saib Xyuas
Residual Dawb Chlorine (yuav tsum tau ntsib GB5749-2022: 0.3-2 mg / u hauv cov nroj tsuag)
Dej Qhov Zoo: NTU), algae cov ntsiab lus, cov teeb meem organic (COD / MN)
Dej Flowage tus nqi (yog tias nws deviates los ntawm cov khoom "tsim qauv dej")
Hloov kho cov qauv tshiab & cov hau kev
2. Kev hloov kho rau kev kho dej phwj tuaj
Txheeb Xyuas Tseem Ceeb Saib Xyuas
Residual Chlorine (tsis muaj tus qauv tsis tsim nyog, tab sis xa mus rau Empirical Ranges: 5-30 mg / l raws li kev kho theem)
Dej Phwj Zoo: COD (cov tshuaj uas muaj tshuaj lom), lub cev (biochemical oxygen thov), tshem tawm cov khib nyiab (ss)
Kev Kho Mob Theem (Thawj / theem nrab / tsis tiav thib ob)
3. Kev hloov kho rau cov dej da dej da dej
Txheeb Xyuas Tseem Ceeb Saib Xyuas
Residual Dawb Chlorine (GB37488-2019: 0.3-1.0 mg / u; koob tshuaj zoo: 2 mg / l)
Tus Neeg Siv Thauj (Tus naj npawb ntawm cov neeg ua luam dej ib teev)
Dej kub (ntau dua lossis sib npaug rau 28℃accelerates noj tshuaj)
pH value (optimal 7.2–7.8; pH >8 txo cov tshuaj chlorine ua tau zoo)
4. General hloov kho cov kauj ruam (tsim nyog rau txhua qhov xwm txheej)
Soj ntsuam ua ntej: Siv cov kab hluav taws xob uas tseem ceeb tshaj plaws (lossis online sensor) los sim ua cov ntsiav tshuaj tam sim no; Ib txhij teev cov ntawv dej zoo (xaim / cod) thiab ntws / thauj khoom.
Xam hloov kho kev kho kom haum: raws li tus txhais ua kom zoo (piv txwv li, ntws mus txog 0.2 mg / l), rov hais dua cov neeg yuav tsum muaj tshuaj chlorine (G / H) ntawm cov qauv tseem ceeb.
Kho lub tshuab hluav taws xob: hloov kho lub tshuab hluav taws xob cov zis tawm (ntawm kev tswj hwm vaj huam sib luag / txo cov ntsev ntxiv lossis ntsuas cov tshuaj chlorine.
Txheeb xyuas & ruaj khov: kev sim cov tshuaj hauv cheeb tsam 30 feeb-1 teev tom qab hloov kho; Yog tias nws raws cov qauv, khaws cov koob tshuaj tshiab; Yog tias tsis yog, rov ua cov kauj ruam 2-3 (nplua - saib los ntawm 0.1-0.3 mg / l txhua lub sijhawm).
