Cov khoom siv lim dej rau lub thoob dej yug ntses yog qhov tseem ceeb los xyuas kom meej tias dej zoo thiab muab ib puag ncig zoo rau cov ntses. Cov kab mob ntau dua hauv lub thoob dej yug ntses, qhov tsim nyog dua los lim. Muaj ntau hom khoom siv lim rau lub thoob dej yug ntses, kuv yuav qhia ntau hom uas siv ntau heev.
Nta: Cov khoom siv lim dej feem ntau siv muaj cov qhov loj thiab permeability zoo, uas tuaj yeem cog cov kab mob nitrifying.
Kev Ua Haujlwm: Feem ntau yog siv los ntes cov khoom me me xws li cov khoom noj seem thiab cov quav ntses hauv cov thoob dej ntses.
- Cov pa roj carbon ua kom sov
Cov yam ntxwv: Cov khoom siv carbonaceous uas muaj peev xwm nqus tau cov khoom me me, cov xim, cov ntxhiab tsw, thiab lwm yam hauv dej.
Kev Ua Haujlwm: Tshem tawm cov tshuaj lom neeg tawm hauv dej, tab sis yuav tsum tau ceev faj thaum siv nws. Yog tias lub thoob ntses tab tom ntxiv tshuaj, cov pa roj carbon activated yuav tsum tau tshem tawm ua ntej kom tsis txhob muaj cov tshuaj lom neeg.
Yam ntxwv: Qhov ceev ceev, tawv tawv, feem ntau yog xim dub lossis xiav xiav.
Kev Ua Haujlwm: Nws muaj ob qho tib si lub cev thiab kev lim dej ntawm cov kab mob, tuaj yeem cog cov kab mob nitrifying, thiab rhuav tshem cov tshuaj lom xws li ammonia thiab nitrite hauv dej.
Yam ntxwv: Qhov chaw roughness, cov qauv porous, tsim rau kev txuas ntawm cov kab mob nitrifying thiab lwm yam kab mob me me.
Kev Ua Haujlwm: Muab qhov chaw rau kev loj hlob ntawm cov kab mob nitrifying thiab pab rhuav tshem cov tshuaj lom xws li ammonia thiab nitrite hauv dej.
Nta: Cov qauv ntau daim ntawv, sab hauv porous, thaj chaw loj, tsim rau kev cog cov kab mob nitrifying.
Kev Ua Haujlwm: Nws yog qhov tshwj xeeb tshaj yog rau kev siv hauv cov lim dej ntws, tab sis nws tsis pom zoo kom ntub nws ncaj qha rau hauv dej vim nws yuav pov tseg nws cov haujlwm coj kev ntws ntawm qhov chaw.
Cov yam ntxwv: Zoo ib yam li lub nplhaib ceramic loj dua, nws muaj cua zoo thiab qhov chaw ntxhib.
Kev Ua Haujlwm: Siv rau kev cog cov probiotics, pab ntxuav cov dej kom huv, tsim nyog rau cov thoob dej loj hauv qab lim dej.
- Mbbr lim dej
1. MBBR cov khoom siv filler feem ntau yog ua los ntawm cov khoom siv polyethylene (HDPE), uas muaj kev tiv thaiv corrosion zoo thiab kub kub.
2. Qhov saum npoo ntawm cov khoom siv filler muaj ntau cov qauv me me concave convex, uas ua rau thaj chaw tshwj xeeb thiab muab ntau cov ntsiab lus txuas.
3. MBBR cov khoom siv filler media yog qhov sib dua thiab tuaj yeem txav mus los hauv dej yam tsis tau nyob hauv qab.
4. Vim nws tsim tshwj xeeb, MBBR lim xov xwm muaj thaj chaw loj dua thiab tuaj yeem txhawb nqa kev loj hlob ntawm biofilm.
5. Tus qauv tsim ntawm Mbbr lim dej tso cai rau dej ntws kom sib npaug, zam kev tsim cov cheeb tsam tuag thiab txhim kho kev ua haujlwm ntawm cov tshuaj tiv thaiv.
