MBR System FAQs & Solutions

Xyoo 2022-08-19

Membrane bioreactor yog cov cuab yeej siv dej kho dej uas sib xyaw ua ke cov txheej txheem membrane thiab biochemical cov tshuaj tiv thaiv hauv cov dej phwj tuaj. Membrane bioreactor (MBR) lim cov dej phwj hauv biochemical cov tshuaj tiv thaiv tank nrog daim nyias nyias thiab cais cov sludge thiab dej. Ntawm ib sab, daim nyias nyias cuam tshuam cov kab mob hauv cov tshuaj tiv thaiv tank, uas ua rau kom cov concentration ntawm cov activated sludge nyob rau hauv lub tank mus rau theem siab, thiaj li hais tias cov biochemical cov tshuaj tiv thaiv ntawm cov dej khib nyiab degradation khiav sai thiab meej. Ntawm qhov tod tes, cov dej ntau lawm yog huv si thiab meej vim siab pom precision ntawm daim nyias nyias.

Txhawm rau pab txhawb kev ua haujlwm thiab kev saib xyuas ntawm MBR, daws cov teeb meem hauv cov txheej txheem kev ua haujlwm raws sijhawm, cov teeb meem tshwm sim thiab cov kev daws teeb meem tau sau tseg raws li hauv qab no:

FAQ	Yog vim li cas	Kev daws
Kev txo qis ntawm flux sai Kev nce nrawm ntawm trans membrane siab	Substandard influent zoo	Pretreat thiab tshem tawm cov roj & roj, organicsolvent, polymeric flocculant, epoxy resins txheej, yaj teeb meem ntawm ion pauv resin, thiab lwm yam.
	Abnormal aeration system	Teem tsim nyog aeration siv thiab cov huab cua sib xws (kab rov tav installation ntawm daim nyias nyias)
	Ntau dhau concentration ntawm activated sludge	Txheeb xyuas qhov concentration ntawm cov activated sludge thiab kho nws mus rau qib qub ntawm kev tswj xyuas
	Ntau dhau ntawm daim tawv nqaij flux	Txo tus nqi nqus, txiav txim siab tsim nyog flux los ntawm kev sim
Cov zis dej tsis zoo deteriorates Turbidity nce	Kos los ntawm cov khoom loj hauv cov dej nyoos	Ntxiv 2 hli zoo tshuaj ntsuam ua ntej membrane system
	Kev puas tsuaj thaum ntxuav lossis khawb los ntawm cov khoom me me	Kho lossis hloov cov txheej membrane
	Connector leakage	Kho qhov taw tes ntawm cov membrane element connector
	Membrane kev pab cuam lub neej tas sij hawm	Hloov cov txheej membrane
Aeration yeeb nkab yog thaiv Aeration tsis sib xws	Tsis tsim nyog tsim ntawm aeration pipeline	Downward qhov ntawm aeration yeeb nkab, pore loj 3-4mm
	Aeration pipeline tsis siv ntev, sludge ntws mus rau hauv cov kav dej aeration thiab thaiv cov pores	Thaum lub sij hawm kaw lub kaw lus, ib ntus pib nws ib pliag kom cov kav dej tsis thaiv
	Lub tshuab tsis ua haujlwm	Teem lub kos valve ntawm cov kav dej kom tiv thaiv cov dej phwj rov qab mus rau lub tshuab
	Membrane ncej tsis horizontally ntsia	Membrane thav duab yuav tsum tau ntsia rau kab rov tav thiab khaws cov qhov aeration ntawm tib qib kua
Lub peev xwm tsim dej tsis ncav cuag tus nqi tsim	Tsawg flux thaum pib tshiab system	Kev xaiv lub twj tso kua mis tsis tsim nyog, kev xaiv tsis tsim nyog ntawm lub qhov pore membrane, thaj chaw me me, tsis sib haum ntawm cov kav dej, thiab lwm yam.
	Membrane kev pab lub neej tas sij hawm los yog fouling	Hloov los yog huv membrane modules
	Tsawg dej kub	Nce dej kub los yog ntxiv cov khoom membrane
