Ubuchwephesha be-MBR buguqula ukucocwa kwamanzi amdaka ngokuSebenza okuPhezulu

MBR(inwebu I-Bio-Reactor) yinkqubo yokucoca amanzi amdaka esebenza kakuhle kakhulu edibanisa unyango lwebhayoloji lwendabuko (njengendlela yokulahla inkunkuma esebenzayo) kunye netekhnoloji yokwahlula i-membrane. Eyona nto iphambili kuyo kukutshintsha itanki yendabuko yokulahla inkunkuma yesibini nge-ultrafiltration okanye i-microfiltration membrane (ubungakanani be-pore 0.01 ~ 0.4 μm) ukuze kufezekiswe ukwahlulwahlulwa kwamanzi amdaka kunye nokuphucula umgangatho wokungcola ngaxeshanye. inwebu yembr Itekhnoloji iqala ngokususa ungcoliseko lwezinto eziphilayo olubolayo emanzini ngokusebenzisa udaka olusebenzayo, ize emva koko isebenzise iimodyuli ze-membrane ukuze ithintele udaka olusebenzayo kunye noninzi lwezinto eziqinileyo ezixhonyiweyo kwi-bioreactor ukuze kufezekiswe ukwahlulwa kolwelo oluqinileyo lwamanzi acocekileyo kunye nodaka olusebenzayo, ngaloo ndlela iqinisa impendulo ye-biochemical kwaye iphucule isiphumo sonyango lwelindle kunye nomgangatho wokungcola.

Inkqubo yonyango ye-MBR yayinempembelelo enkulu kunyango lwe-COD kumanzi amdaka kushishino lwesichumisi se-nitrogen, kunye neentlobo ze-biochemical zinenqanaba elifutshane lempilo kunye nokukhawuleza, kwaye umphumo wawuzinzile ukususela ngosuku lwesithathu. Kuzo zombini inqanaba lonyango oluzinzileyo kunye nenqanaba lokusebenza eliqhelekileyo, izinga lokususa i-COD lingagcinwa, kwaye izinga lokususa ngokusisiseko lingaphezulu kwe-90%. Umndilili we-COD yokuthumela ngaphandle ilawulwa ngaphantsi kwe-30mg/L.

I-MBR yindibaniselwano esebenzayo yetekhnoloji yokwahlula inwebu kunye nendlela yonyango lwebhayoloji, kwaye imvelaphi yayo kukubuyisela itanki yentlenga yesibini kwindlela yodaka olusebenzayo kunye neteknoloji yokwahlula inwebu yokwahlulwa kolwelo oluqinileyo. Le nkqubo ayiphumeleli kuphela ngokufanelekileyo injongo yokwahlulwa kodaka, kodwa ineengenelo ezingenakuthelekiswa nanto zenkqubo yemveli yokucocwa kogutyulo lwelindle:

1. Ukwahlula okusebenzayo okuqinileyo-olulwelo, umphumo wokwahlula ungcono kakhulu kunetanki yentlenga yesiqhelo, umgangatho wamanzi amdaka ulungile, ukungcola okunyhashiweyo okuxhonyiweyo kunye ne-turbidity kusondele kwi-zero, kwaye kunokusetyenziswa ngokuthe ngqo kwakhona, ukuqonda ukuphinda kusetyenziswe ugutyulo.

2. Impembelelo esebenzayo yokuthintela i-membrane yenza i-microorganisms ibanjwe ngokupheleleyo kwi-bioreactor, iqonda ukuhlukana okupheleleyo kwexesha lokugcinwa kwe-reactor hydraulic retention (HRT) kunye nobudala be-sludge (SRT), kwaye ulawulo lokusebenza luguquguqukayo kwaye luzinzile.

3. Ngenxa yokuba i-MBR idibanisa itanki yokufaka umoya kunye nesesibini sedimentation tank yokucoca ugutyulo lwelindle ibenye, kwaye ithathela indawo yonke inkqubo yonyango oluphezulu, inokunciphisa kakhulu umgangatho kwaye isindise utyalo-mali lobunjineli boluntu.

4. Kukulungele ukungenelela kunye nokuveliswa kwebhaktheriya ye-nitrifying, kwaye inkqubo inokusebenza okuphezulu kwe-nitrification. Ngokutshintsha kwendlela yokusebenza, inokuba nomsebenzi we-deammonization kunye nokususwa kwe-phosphorus.

5. Ngenxa yokuba ixesha lodaka linokuba lide kakhulu, ukusebenza kakuhle kokuthotywa kwe-refractory organic matter kuphuculwe kakhulu.

6. I-reactor isebenza phantsi komthwalo ophezulu we-volumetric, umthwalo ophantsi we-sludge kunye nobudala be-sludge ende, kunye nokukhutshwa kwe-sludge eseleyo kuphantsi kakhulu.

7. Inkqubo iqonda ulawulo lwe-PLC, kwaye ukusebenza kunye nolawulo lufanelekile
