Vim yog muaj ntau yam dej khib nyiab hauv kev lag luam thiab hauv tsev, peb muaj cov khoom siv kho dej sib txawv los kho thiab ntxuav cov dej kom huv si kom ua tau raws li cov kev xav tau thiab lub hom phiaj sib txawv.
Ib lub hnab ntim khoom uas muaj qhov nqus dej uas ua los ntawm cov polyethylene siab (HDPE) nrog cov qauv tshwj xeeb ntawm qhov chaw kom nce thaj chaw tshwj xeeb (feem ntau yog 500-900 ㎡/m ³), nrog qhov ceev ze rau dej (0.96-0.98 g/cm ³), thiab tuaj yeem txav mus los tau yooj yim nrog dej ntws.
Daim Ntawv Thov:
Siv rau cov thoob dej biochemical hauv cov chaw kho dej phwj tuaj (xws li AO, AAO cov txheej txheem), kev kho dej khib nyiab hauv kev lag luam (khoom noj, tshuaj, thiab lwm yam), kev kho dua tshiab ntawm tus dej, thiab lwm yam.
Cov txiaj ntsig:
Tsis tas yuav tsum muaj cov brackets ruaj khov, txuag kev siv hluav taws xob;
Cov biofilm muaj peev xwm ua kom rov ua dua tshiab thiab tiv taus kev poob siab;
Lub kaw lus sludge uas twb muaj lawm tuaj yeem hloov kho dua tshiab.
Qauv:
Lub hauv nruab nrab yog ib txoj hlua yas lossis ib pob fiber, qhwv ib ncig ntawm ib lub nplhaib yas "zoo li paj daus" lossis xov fiber los ua ib lub qauv mesh peb-seem.
Kev Ua Haujlwm:
Kev loj hlob ntawm cov kab mob sib txuas ua ke qhov chaw siab ntawm cov khoom siv mos mos nrog lub zog kho tshuab ntawm cov khoom siv semi-soft.
Daim Ntawv Thov:
Cov thoob dej oxidation, cov thoob dej hydrolysis acidification, cov chaw lim dej biological, thiab lwm yam yog qhov tsim nyog rau cov dej khib nyiab organic uas muaj cov concentration siab (xws li kev tua tsiaj, kev luam ntawv thiab kev zas xim dej khib nyiab).
Khoom siv:
Cov xov polyester lossis polyethylene raug xaws ua cov hlua lossis cov strips, nrog rau qhov chaw ntxhib uas yooj yim lo rau zaj duab xis.
Qhov Zoo:
Kev teeb tsa ntsug, tsim rau cov pas dej tob;
Corrosion resistant, nrog lub neej ntev tshaj 10 xyoo.
Daim Ntawv Thov:
Kev kho dej hauv dej hiav txwv aquaculture, lwm txoj hauv kev siv MBBR, thiab kev kho kom zoo dua ntawm cov av noo dag.
Feem ntau nws yog ib lub thawv yas modular (xws li PP khoom) nrog lub honeycomb lossis corrugated board qauv sab hauv, thiab porosity ntawm> 90%.
Kev Ua Haujlwm:
Cov dej khib nyiab ntws los ntawm txheej ntim khoom los ntawm sab saud mus rau hauv qab thiab kov tau huab cua kom ua tiav kev puas tsuaj ntawm cov organic thiab nitrification.
Daim Ntawv Thov:
Kev kho dej phwj tsis muaj chaw nruab nrab hauv cov zos thiab cov nroog, kev kho cov dej khib nyiab, thiab cov lim dej tsw ntxhiab.
Hom:
Daim txhuam cev hydrophilic nrog qhov qhib ntawm ≥ 95%, nrog qhov loj me ntawm qhov hws hloov kho tau (xws li 10-60 PPI).
Cov txiaj ntsig:
Ntes cov khoom khov uas raug tshem tawm thaum cog cov kab mob anaerobic/aerobic;
Yooj yim los ntxuav thiab rov ua dua tshiab, tsim rau cov khoom siv me me.
Daim Ntawv Thov:
Cov ntses thiab zaub sib xyaw ua ke, kev lim dej nag, MBR membrane pretreatment.
Cov hom uas feem ntau siv:
Lub tshuab ua pa me me (EPDM membrane, lub voj voog npuas 1-3 hli, tus nqi siv oxygen ≥ 30%);
Cyclone aerator (tiv thaiv kev txhaws, tsim nyog rau cov dej khib nyiab SS siab);
Cov yeeb nkab aerator (yooj yim rau nruab, feem ntau siv rau cov dej khib nyiab hauv kev lag luam).
Cov ntsiab lus xaiv tseem ceeb:
Raws li qhov ntim cua, qhov tob ntawm dej, thiab qhov concentration ntawm cov sludge, yuav tsum tau ntxuav tsis tu ncua kom tiv thaiv kev thaiv.
Khoom siv:
Stainless hlau 316L lossis ABS engineering yas, nrog qhov dav sib txawv ntawm 0.2-0.5 hli.
Kev Ua Haujlwm:
Nruab rau hauv qab ntawm lub phaj lim, faib dej / cua kom sib npaug, thiab tiv thaiv kev poob ntawm cov khoom siv lim thaum lub sijhawm rov qab ntxuav.
Cov Lus Qhia:
Feem ntau siv rau cov lim dej zoo li V thiab cov kem pauv ion, nrog cov tes tuav ntev thiab luv thiab tus nqi ntws ntawm 1-2m ³/h ib chav.
Cov Lus Qhia:
Kev kho dej khib nyiab:MBBR lim meida + ua ke filler + cyclone aerator;
Kev lim tob tob:Lim nozzle + lim ua npuas ncauj;
Cov khoom siv me me:bio trickling lim media + kauv hlua braided hlua filler
