Nyob rau hauv cov txheej txheem ntawm cov dej phwj tuaj, a
Ntau dhau aeration
Ntau qhov tshwm sim yog hais txog qhov tshwm sim uas tus nqi txhaj tshuaj oxygen txhaj rau hauv dej ib lub sijhawm ntau dua qhov xav tau ntawm cov kab mob dej thaum lub sijhawm dej kho mob. Kev Aeration ntau dhau yuav ua rau cov hauv qab no:
1. Desolved oxygen (ua) concentration yog ntau dhau
2. Sludge kev laus
3. Sludge nthuav dav
4. Cov nyhuv txo
5. Khib ntawm lub zog
Qhov cuam tshuam ntawm kev ua haujlwm ntau dhau hauv kev kho kom muaj dej
1. Ua kom nrawm nrawm
Ntau dhau ntawm kev ua haujlwm tuaj yeem ua rau muaj kev sib txuam ntawm cov pa oxygen, ua rau cov kab mob sib txawv, ua rau cov kab mob sib kis tau ua lub xeev ntawm oxidation ntau dhau. Hauv qhov no, cov metabolic tus nqi ntawm cov kab mob metabganisms accelerates, sludge muaj hnub nyoog luv, thiab cov kev ua haujlwm txo qis.
Thaum cov ntawv tshwm sim hauv qab no tshwm sim, nws qhia tau tias lub sludge yuav muaj hnub nyoog:
(1) Sescated Sludge ntim ntsuas phoo (SVI): Svi yog qhov taw qhia ntawm sludge daws kev ua tau zoo, thiab ntau dua svi tus nqi, qhov tsis zoo tshaj plaws sludge daws kev ua tau zoo. Thaum ntau dhau kev ua kom loog rau sludge laus, tus nqi svi yuav nce ntxiv.
(2) Cov xim ntawm sludge ua ntais: nyob rau hauv ib txwm muaj xwm txheej, ua kom zoo sludge tshwm xim dub lossis xim av. Ntau dhau Aeration ua rau txo qis qis rau hnub nyoog thiab maj me me hauv cov xim.
(3) Cov xoob xoob ntawm sludge: ntau dhau ntawm kev ua kom dhau los ua rau cov microorganism hauv cov flocs, ua rau xoob xoob thiab tawg yooj yim.
Cov kev ntsuas hauv qab no tuaj yeem raug coj los daws qhov teeb meem ntawm sludge laus:
(1) Mob siab rau sludge tso tawm: Muaj hnub nyoog tsis tu ncua, txo qis qis hnub nyoog, thiab saib xyuas cov haujlwm sludge.
(2) Kho lub nra: thaum lub nra hnyav dhau, cov as-ham tuaj yeem txuas ntxiv lossis cov roj hmab kev loj hlob, thiab qeeb qeeb qeeb kev laus.
(3) Txo cov pa oxygen yaj: los ntawm kev kho cov khoom siv Aeration thiab txo cov pa Aeration, cov pa oxygen tuaj yeem raug tswj kom muaj kev tsim nyog.
2. Sludge nthuav dav
Ntau dhau ntawm aeration tuaj yeem ua rau cov pa oxygen ua rau muaj kev kub ntxhov dhau los, ua rau cov kab mob overgrowth thiab tsim ntawm ntau ntawm cov npuas. Cov npuas no ua rau cov sludge flocs, ua rau ib tug poob qis hauv sludge ceev thiab ua rau sludge o. Sludge nthuav kev tuaj yeem ua rau cov teeb meem hauv qab no:
(1) Cov kev ua tsis zoo ntawm sludge daws kev ua tau zoo cuam tshuam rau qhov zoo effluent zoo.
(2) sludge poob nce qhov nyuaj ntawm kev kho tom ntej.
(3) Cov khoom thauj ntawm cov khoom siv AERERATER ANANTS, uas ua rau muaj kev nce hauv kev siv hluav taws xob.
Txhawm rau tiv thaiv sludge nthuav dav, ntsuas hauv qab no tuaj yeem coj:
(1) Kho tus nqi aeration kom tswj cov pa ocygen concentration nyob rau hauv ib qho tsim nyog.
(2) ntxiv dag zog rau sludge reflux thiab nce sludge concentration.
(3) Ntxiv coagulants los txhim kho sludge daws kev ua tau zoo.
3. Cov nyhuv txo
Kev Aeration ntau dhau yuav ua rau cov teeb meem hauv qab no, uas nyob rau hauv lem cuam tshuam rau cov nyhuv kho:
(1) Txo cov kev ua haujlwm sludge: ntau dhau ntawm kev ua kom dhau los ua rau cov kab mob ntawm cov kab mob ntawm cov kab mob thiab cuam tshuam rau qhov kev ua tsis raws li orgeic.
(2) Kev rhuav tshem ntawm sludge Floc qauv: ntau dhau ntawm kev ua txhaum rau cov so ntawm sludge flocs, cuam tshuam rau cov adsorption thiab kev tsis txaus siab ntawm cov kab mob me me.
(3) Kev hloov pauv hauv cov pa oxygen ua rau muaj kev hloov pauv hauv kev hloov pauv pa, cuam tshuam rau kev loj hlob ib puag ncig, ib puag ncig kev loj hlob ntawm cov kab mob sib xws.
Tus txheej txheem aeration yuav tsum muaj qhov tseem ceeb ntawm kev siv hluav taws xob. Ntau lub aeration tsis tsuas yog ua tsis tiav los txhim kho kev txuag nyiaj, tab sis qee zaum kev siv hluav taws xob ntau dua 50% ntawm kev siv hluav taws xob hauv txhua cov dej phwj tuaj.
Yuav ua li cas kom tsis txhob muaj kev mob siab rau hauv dej phwj
1. Ua kom zoo rau cov khoom siv pov tseg kom muaj zog: Xaiv txuag thiab txuag hluav taws xob pa taws kom txhim kho kev siv oxygen thiab txo kev siv hluav taws xob. Zog kev ua haujlwm submicible submersible ererators tau muab los ntawm peb, koj tuaj yeem tshawb xyuas peb cov khoom lag luam hauv peb cov kev xav tau, yuav pom zoo cov qauv, yuav raug pom zoo.
2. Lub sijhawm saib xyuas lub sijhawm: los ntawm kev siv cov cuab yeej saib xyuas online, ntsuas kom haum rau hauv lub sijhawm, thiab cov kev ntsuas Aeration tuaj yeem hloov kho raws li qhov xwm txheej tiag tiag.
3. Kev tswj ntse tswj: Siv lub khoos phis tawj kom hloov kho cov txheej txheem AERLation thiab tswj cov pa oxygen nyob rau hauv ib qho uas tsim nyog.
