MBBR (Moving Bed Biofilm Reactor) siv cov khoom siv yas biofilm tshem tawm dawb los pab txhawb kev loj hlob ntawm microbial. These plastic carriers have a density close to that of water and remain suspended through continuous aeration, ensuring effective contact between pollutants and the attached biofilm for efficient BOD removal.
Cov yam ntxwv ntawm MBBR:
1. Kev tsim kho yooj yim thiab kev ua haujlwm yooj yim.
2. High organic tshem tawm efficiency nrog zoo nitrogen thiab phosphorus tshem tawm.
3. Resistant rau clogging thiab tsis tas yuav rov qab ntxuav.
4. Yuav tsum muaj cov txheej txheem sedimentation tom qab kho.
MBR (Membrane Biofilm Reactor) yog cov txheej txheem uas sib xyaw ua ke cov txheej txheem sib cais nrog cov activated sludge. Feem ntau cov tshuab MBR yog submerged hauv cov dej khib nyiab, siv cov kab mob uas txuas nrog rau daim nyias nyias kom degrade organic teeb meem.
Feature ntawm MBR:
1. Muaj peev xwm ua haujlwm nyob rau hauv siab ntim loading thiab tsis tshua muaj sludge loading, ua rau qis tshaj sludge ntau lawm (theoretically ua tiav xoom sludge paug) thiab txo cov nqi kho sludge.
2. Ua kom siab MLSS concentration nyob rau hauv lub reactor, tso cai rau siab ntim loading thiab txo hneev taw.
3. Cov kab mob microbial siab yuav tsum muaj aeration txaus, ua rau muaj kev siv zog ntau dua.
4. Ntxim rau daim nyias nyias fouling, yuav tsum tau periodic membrane tu los yog rov qab ntxuav.
FBR (Fixed Bed Biofilm Reactor) ua haujlwm ntawm lub hauv paus ntsiab lus zoo ib yam li MBBR, nrog qhov sib txawv tseem ceeb yog tias biofilm txuas rau cov khoom siv ruaj khov. Aeration yog muab rau hauv qab cov khoom siv los muab cov pa oxygen rau biofilm kev loj hlob thiab tswj kev tu biofilm.
Feature ntawm FBR:
1. Muaj peev xwm kho cov dej khib nyiab nrog kev hloov pauv loj hauv cov dej ntws thiab cov ntsiab lus organic.
2. Kev ua haujlwm yooj yim dua thiab kev siv hluav taws xob qis dua piv rau MBBR (vim ncaj qha hauv qab aeration).
