"Iqhawe elingabonakaliyo" kwi-Sewage Treatment - i-Biological Filler

Ngaba wakha wazibuza ukuba njaniIzixhobo zokucoca ugutyuloUkuguqula ilindle elimdaka libe ngamanzi acocekileyo? Ukongeza kwiminikelo ye-microorganisms, kukho kwakhona izinto eziphathekayo ezincedisayo - i-biological filler. Kufana "nendlu yendalo" emanzini, ukubonelela ngendawo yokuhlala ye-microorganisms kunye nokuphinda kabini ukusebenza kakuhle kokucocwa kwamanzi amdaka. Namhlanje, makhe sijonge eli "gorha elingabonakaliyo"!

I. Yintoni isihluzi sebhayoloji?

Ingcaciso:I-Biofiller yeyona nto iphambili ekuphatheni inkqubo yokucocwa kwamanzi amdaka e-biofilm, idla ngokuba yi-porous, i-high-surface-area solid substance. Iyakwazi ukubhengeza ii-microorganisms ukwenza i-biofilms kwaye isuse ungcoliseko ngokusebenzisa i-biodegradation kunye ne-adsorption yomzimba.
Imisebenzi engundoqo:
Ukubonelela ngendawo yokuba ii-microorganisms zincamathele kwaye zandise i-biomass ngomthamo weyunithi nganye.
Yandisa ixesha lokuhlala le-microorganisms kunye nokuphucula ukusebenza kakuhle kokususa izinto ezingcolileyo eziyinkimbinkimbi (ezifana ne-ammonia nitrogen kunye ne-organic matter).

Umzobo.1 Inkqubo yokwenziwa kwebhayoloji yesigcwalisi sebhayoloji

II. Iimpawu zokugcwaliswa kwebhayoloji

1. Uyilo lokuphucula ukusebenza kweHydraulic
Iipropati ze-fluid mechanics fillers zebhayoloji zibonakaliswa ubukhulu becala kwimilinganiselo emine: indawo ethile yomphezulu, ubume bepore, imorphology yejometri kunye nokupakisha ukuxinana. Umgangatho ophezulu womgangatho othile yimeko esisiseko yokugcina ugxininiso oluphezulu lwe-biomass kwi-reactor, kwaye inqanaba le-biomass limisela ngokuthe ngqo ukuthotywa kokungcoliseka kokuchaneka kwenkqubo. Nangona kunjalo, ukonyuka kwendawo ethile kuya kwandisa ukuxhathisa ulwelo ngaxeshanye, okukhokelela ekunyukeni kokusetyenziswa kwamandla omoya.

Ubungakanani be-porosity buchaphazela ngokuthe ngqo ukusetyenziswa komthamo osebenzayo we-reactor. I-porosity ephezulu inokwandisa ixesha langempela lokuhlala lamanzi amdaka, ukunciphisa ukuchasana kokuhamba, ukunciphisa umngcipheko wokuvaleka kunye nokuhamba okufutshane, kunye nokunciphisa inani le-biological filler kunye neendleko zeziseko.

2. Iimfuno zokuzinza kweekhemikhali
I-biofiller kufuneka ibe ne-corrosion-resistant kwaye ikwazi ukumelana nokukhukuliseka kwamacandelo amanzi amdaka kunye ne-microbial metabolites. Izinto eziphathekayo ngokwazo kufuneka zibe ne-inert ukuphepha ukuchithwa kwezinto ezinobungozi ezibangela ukungcola okwesibini, kwaye akufanele zibe neekhemikhali ezivimbela umsebenzi we-microbial. Umgangatho womzimba kufuneka uhlangabezane neemfuno zamandla omatshini ngelixa ugcina iimpawu ezilula ukunciphisa umthwalo wenkqubo.

3. Iinkqubo ezikhuthaza uncamathiselo lwebhayofilm
Ukusebenza kokubunjwa kwe-biofilm kuxhomekeke kwiipropati ze-physicochemical ze-biofiller:

Iimpawu ezibonakalayo:Uburhabaxa bomphezulu kunye nesakhiwo se-microporous zizinto eziphambili. Imiphezulu erhabaxa inokukhawulezisa inkqubo yokwenziwa kwebhayofilm, ngelixa izakhiwo ze-microporous zonyusa ukugcinwa kwe-microbial ngokusebenzisa isenzo se-capillary.

Iimpawu zemichiza:Iimpawu zokuhlawula umphezulu kunye neepropati ze-hydrophilic kunye ne-hydrophobic zidlala indima ephambili. Umphezulu webhaktheriya udla ngokuhlawuliswa kakubi, kwaye amandla afanelekileyo kumphezulu we-biofiller anokukhuthaza ukuncamathelwa kweeseli ngokusebenzisa i-electrostatic adsorption. Imiphezulu ye-Hydrophilic inokunciphisa kakhulu umjikelo wokwenza i-biofilm.

4. Iimpawu zezinto eziphathekayo
Ukulinganisela kufuneka kubethelwe phakathi kokukhanya kunye namandla aphezulu. I-biofiller efanelekileyo kufuneka ibe namandla okwaneleyo okucinezela ukuxhathisa impembelelo yokuhamba kwamanzi, ngelixa igcina ubuninzi obuphantsi ukunciphisa ukusetyenziswa kwamandla kwenkqubo.

5. Iingqwalasela zezoqoqosho
Iindleko ze-biofillers zidla ngokubala i-30% -40% yotyalo-mali lulonke kwinkqubo ye-biofilm, ngoko ke kubalulekile ukukhetha izinto ezingabizi kakhulu. Imathiriyeli ekrwada enoluhlu olubanzi lwemithombo kunye nokusetyenzwa okufanelekileyo kufuneka kukhethwe ukuphumeza ukuphuculwa kweendleko ngelixa uqinisekisa ukusebenza.

III. IThekhnoloji "yeQela eliQelekileyo" leBiofillers

1.MBBR(I-Bed eshukumayo ye-Biofilm Reactor)
Iimbonakalo:Isigcwali sebhayoloji sihamba ngokukhululekileyo echibini, kwaye akukho kuhlamba umva kuyadingeka.
Iyasebenza:Ugutyulo logutyulo oluphezulu, ukuphuculwa kwezixhobo ezidala zokucocwa kwelindle.

Isazobe 2. Ukusetyenziswa okusebenzayo kwenkqubo ye-MBBR yokugcwaliswa kwebhayoloji

2. Biological contact oxidation ichibi
Iimbonakalo:Izihluzi zebhayoloji zimiselwe echibini kwaye kufuneka zicocwe rhoqo.
Iyasebenza:ugutyulo lwasekhaya, amanzi amdaka aphantsi koxinaniso lwemizi-mveliso.

IV. Isishwankathelo: Khetha isigcwali sebhayoloji esifanelekileyo ukwenza unyango lwelindle lusebenze ngakumbi

Isigcwalisi sebhayoloji "lilitye lembombo yendalo" yokucoca ilindle. Ukukhetha izinto ezifanelekileyo kunye nenkqubo kunokuphucula kakhulu umphumo wonyango. Kwixesha elizayo, ngokuphuculwa kweemfuno zokhuseleko lokusingqongileyo, izihluzi ezintsha zebhayoloji ezifana negraphene kunye ne-zeolite ziya kuba yindawo yophando.

Ixabiso lobuchwephesha lokuzalisa i-biological fillers alibonakali nje ekucocweni kwamanzi ngokwalo, kodwa nangokudityaniswa kwezinto ezintsha kunye nenkqubo, likhuthaza ukucocwa kwelindle ngokubhekiselele kwikhabhoni ephantsi kunye nophuhliso olusekelwe kubutyebi, kwaye luba yinkxaso yobugcisa eyimfuneko kwinkqubo yolawulo lwangoku lwamanzi.
