Cov Khoom Siv Kho Dej Pov Tseg: Cov Yam Tseem Ceeb Rau Cov Neeg Siv Khoom
Hauv kev kho cov dej khib nyiab, cov khoom siv (lossis cov khoom nqa) yog cov "chav tsev" rau cov kab mob me me. Thaum peb cov neeg siv khoom xaiv cov khoom siv, lawv tsis yog tsuas yog saib tus nqi xwb - lawv tsom mus rau qhov ua tau zoo ntawm biofilm, lub neej ntev, thiab kev nyuaj rau kev saib xyuas.
Nov yog cov lus nug uas cov neeg siv khoom feem ntau nug, nrog rau cov kev nkag siab txog kev tshaj lij uas lawv tab tom nrhiav:
- "Yuav siv sijhawm ntev npaum li cas rau cov biofilm los tsim?"
Cov Lus Teb: Nws nyob ntawm qhov kub ntawm dej thiab cov organic load. Feem ntau, nyob rau hauv ib puag ncig ntawm 20°C thiab 30°C, aerobic biofilm yuav siv sijhawm 7–15 hnub, thaum anaerobic biofilm yuav siv sijhawm 15–30 hnub.
Lub Tswv Yim Zoo: Hais txog kev hloov pauv hydrophilic (ntxiv cov pawg polar rau saum npoo). Cov thev naus laus zis no ua rau cov kab mob pib sib txuas sai dua.
- "Qhov chaw tshwj xeeb uas siv tau zoo yog dab tsi?"
Lub Logic: Thaj chaw loj dua tso cai rau ntau cov kab mob txuas, ua rau muaj peev xwm kho tau ntau dua.
Cov lus teb: Koj yuav tsum paub qhov txawv ntawm thaj chaw theoretical thiab thaj chaw ua haujlwm tau zoo. Yog tias tus neeg nqa khoom raug tsim tsis zoo thiab txhaws sab hauv, thaj chaw sab hauv ntawd yuav dhau los ua "cheeb tsam tuag" thiab tsis muaj txiaj ntsig rau kev kho mob.
- "Nws puas yuav txhaws? Peb yuav kho nws li cas?"
Rau cov xov xwm ruaj khov lossis Tus Neeg Teeb Meem Hauv Rajs, clogging yog ib qho kev ua haujlwm phem heev.
Lub Logic: Kev loj hlob ntawm biofilm ntau dhau lossis cov sludge ntau dhau tuaj yeem thaiv cov channel, ua rau "luv luv" lossis txawm tias cov qauv ntawm cov xov xwm puas tsuaj.
Cov lus teb: * Mbbr Media: Cov no txav mus tas li vim muaj cua nkag, siv kev sib tsoo kom tshem tawm cov biofilm ntau dhau (kev ntxuav tus kheej).
Cov Khoom Siv Ruaj Kho: Yuav tsum tau cov qauv ua kom cua nkag tau zoo lossis ntxuav rov qab tas li kom tiv thaiv cov av qias neeg.
- "Lub neej yuav ntev npaum li cas? Puas yuav tawg yooj yim?"
Lub Logic: Qhov zoo ntawm cov khoom txiav txim siab qhov ruaj khov.
Kev Sib Piv:
Cov Khoom Siv Rov Siv Dua: Nws yooj yim tawg; tej zaum yuav lwj hauv 1-2 xyoos, ua rau TSS (Total Suspended Solids) nce siab hauv cov dej khib nyiab.
Virgin HDPE (High-Density Polyethylene): Nrog UV stabilizers thiab antioxidants, cov no feem ntau kav ntev tshaj 10 xyoo.
- Tus nqi ntim khoom uas pom zoo yog dab tsi?
Lub Logic: Ntau dua tsis yog ib txwm zoo dua.
Cov Lus Qhia: * Rau cov kab ke MBBR, tus nqi sau feem ntau yog ntawm 30% thiab 67%. Tshaj 67% cuam tshuam kev ua kua (kev txav mus los) ntawm cov xov xwm, txo qhov kev hloov pauv oxygen.
Rau Cov Xov Xwm Ruaj Kho, nws feem ntau yog xam los ntawm qhov ntim ntawm thaj chaw nyob hauv qab dej.
Thaum koj nug cov lus nug no, sim nug koj tus kheej ib qho rov qab: "Koj lub tshuab aeration puas muaj zog txaus rau cov xov xwm no?" Feem ntau, kev ua haujlwm tsis zoo ntawm cov xov xwm tsis yog qhov txhaum ntawm cov yas nws tus kheej, tab sis tsis muaj kev sib xyaw kom zoo lossis oxygen, uas ua rau "cheeb tsam tuag" lossis anaerobic sludge accumulation.
