Taw qhia
Cov txheej txheem txav txaj Biofilm Reactor (MBBR) tso siab rau cov xov xwm tshwj xeeb los txhawb kev loj hlob ntawm biofilm rau kev kho dej khib nyiab. Ntawm cov khoom siv feem ntau, High-Density Polyethylene (HDPE) thiab Polypropylene (PP) tau siv dav vim lawv cov kav ntev thiab tshuaj lom neeg ruaj khov. Kab lus no qhia txog lawv cov yam ntxwv ntawm cov khoom siv thiab muab kev taw qhia rau kev xaiv cov xov xwm tsim nyog raws li kev kho mob sib txawv.
Qhov sib txawv tseem ceeb ntawm HDPE thiab PP hauv Cov Khoom Siv Khoom thiab Tus Cwj Pwm
Kev ua tau zoo ntawm MBBR media yog cuam tshuam los ntawm cov khoom siv hauv paus. HDPE thiab PP sib txawv hauv cov qauv molecular, uas cuam tshuam rau lawv lub cev tus cwj pwm hauv kev kho mob.
HDPE has a more linear and dense molecular arrangement, contributing to its strength and resistance to deformation. PP, nrog nws cov qauv molecular, nthuav tawm txawv rigidity thiab thermal teb yam ntxwv. Cov txheej txheem sib txawv no cuam tshuam li cas cov xov xwm coj tus cwj pwm nyob rau hauv kev txav mus tas li hauv cov tso tsheb hlau luam aerated.
Kev tiv thaiv kub yog lwm qhov tseem ceeb. Polypropylene (PP) feem ntau muaj cov ntsiab lus melting nyob rau hauv thaj tsam ntawm 160-170 degree, tso cai rau nws kom muaj kev ntseeg ruaj khov nyob rau hauv qhov kub thiab txias. High-Density Polyethylene (HDPE), nrog lub melting point ntawm kwv yees li 120-135 degree, ua tau zoo nyob rau hauv ntau yam kev khiav hauj lwm ntawm cov dej khib nyiab, uas feem ntau yog nyob nruab nrab ntawm 10-40℃. Cov yam ntxwv thermal no cuam tshuam li cas txhua yam khoom coj ua raws li qhov sib txawv ntawm qhov kub thiab txias hauv kev siv tswv yim.
Tsis tas li ntawd, mechanical tus cwj pwm plays lub luag haujlwm tseem ceeb. MBBR xov xwm tseem nyob tas li, muaj kev sib tsoo thiab kev sib txhuam. Cov khoom vaj khoom tsev cuam tshuam li cas cov xov xwm teb rau ntev - lub sij hawm mechanical stress, uas nyob rau hauv lem influences durability thiab kev khiav hauj lwm sib xws.
Yam tseem ceeb uas yuav tsum tau xav txog thaum xaiv HDPE lossis PP raws li MBBR Media Materials
Kev xaiv cov khoom tsim nyog suav nrog kev tshuaj xyuas ntau yam tseem ceeb ntsig txog kev kho mob.
Cov yam ntxwv dej khib nyiab
Cov dej khib nyiab yog ib qho ntawm cov kev txiav txim siab tseem ceeb thaum xaiv MBBR cov ntaub ntawv xov xwm. Cov dej khib nyiab hauv nroog feem ntau muaj cov khoom siv organic thiab cov khoom noj khoom haus, thaum cov dej khib nyiab tuaj yeem suav nrog cov khoom siv tshuaj lom neeg ntau dua lossis hnyav dua. Cov khoom siv uas tau xaiv yuav tsum tau sib xws nrog cov ntsiab lus tshwj xeeb ntawm cov dej uas raug kho kom ruaj khov thiab txhim khu kev qha.
Cov xwm txheej ua haujlwm
Cov txheej txheem ua haujlwm ua lub luag haujlwm tseem ceeb hauv kev ua haujlwm ntawm cov khoom siv. Cov yam ntxwv xws li kub, aeration siv, thiab hydraulic ntws ncaj qha cuam tshuam li cas cov xov xwm coj tus cwj pwm hauv lub cev. Ib puag ncig uas muaj zog aeration lossis siab txaus yuav ua rau cov xov xwm ua rau muaj kev ntxhov siab ntau ntxiv, xav tau cov khoom siv uas tuaj yeem tswj hwm cov qauv kev ntseeg siab dhau sijhawm.
Biofilm Development Requirements
Kev tsim Biofilm yog qhov tseem ceeb rau kev ua haujlwm ntawm MBBR txheej txheem. Cov khoom nto ntawm cov xov xwm cuam tshuam li cas microorganisms txuas, loj hlob, thiab rov tsim dua tshiab. Tsis tas li ntawd, kev tsim cov xov xwm -xws li nws cov cheeb tsam tshwj xeeb thiab cov qauv sab hauv- ua haujlwm ua ke nrog cov khoom siv los txhawb kev ua haujlwm lom neeg thiab kev kho mob.
Ntev -Lub Sij Hawm Stability thiab Durability
Lub sijhawm ntev - ruaj khov yog qhov tseem ceeb rau kev ua haujlwm tas mus li. MBBR cov xov xwm yuav tsum tiv thaiv tsis tu ncua raug tshuaj lom neeg, lub cev txav mus los, thiab kev hloov pauv ib puag ncig. Cov khoom siv nrog cov khoom ruaj khov pab txo qis kev saib xyuas ntau zaus, ncua kev pab cuam lub neej, thiab ua kom muaj kev kho mob zoo ib yam.
Khoom haum rau txawv daim ntawv thov scenarios
Raws li cov kev xav no, kev xaiv cov khoom siv tau zoo dua thaum ntsuas hauv cov xwm txheej tshwj xeeb hauv kev kho dej khib nyiab.
