Indlela yokujongana ne-RO inwebu yokungcola

Ukungcola kweMembrane kubhekiselele kwinto engenakuguquleka apho amasuntswana, amasuntswana e-colloidal, okanye i-solute macromolecules kwisisombululo sokutya ngokudibana ne-membrane adsorb kunye nediphozithi kumphezulu wenwebu okanye iipores ngenxa yokunxibelelana ngokomzimba okanye kweekhemikhali kunye nenwebu, okanye ukugxilwa kwe-polarization ebangela ukuba izinyibilikisi ezithile zigqithise ukunyibilika kwazo kunye nokuncipha kobungakanani benwebu, isiphumo esibalulekileyo se-membrane kunye nokuncipha kwe-membrane. ukuguquguquka kunye neempawu zokwahlukana.

Usulelo lweMicrobial

1）Izizathu zokuyilwa kwayo

Ungcoliseko lweMicrobial lubhekisa kwinto apho iimicroorganisms ziqokelelana kwi-membrane yojongano lwamanzi, ngaloo ndlela ichaphazela ukusebenza kwenkqubo. Ezi microorganisms ziyaphindaphindeka kwaye zikhule zisebenzisa i-osmosis membranes njengabathwali kunye nezondlo ezivela kwicandelo eligxininisiweyo lamanzi le-osmosis ebuyela umva, zenza umaleko we-biofilm kumphezulu we-osmosis ebuyela umva. Oku kukhokelela ekonyukeni ngokukhawuleza koxinzelelo phakathi kokungena kunye nokuphuma kwenkqubo ye-osmosis ebuyela umva, ukwehla okukhawulezayo kwimveliso yamanzi kunye nesantya sokukhupha ityuwa, kunye nongcoliseko lwamanzi emveliso. I-Biofilm eyenziwe nge-microorganisms inokuthe ngqo (ngesenzo se-enzymatic) okanye ngokungathanga ngqo (nge-pH yendawo okanye ukunciphisa amandla) ukuthobisa iipolymers ze-membrane okanye ezinye iinqununu zeyunithi ye-osmosis, okukhokelela kubomi obufutshane be-membrane, umonakalo kwingqibelelo yesakhiwo senwebu, kunye nokungaphumeleli okukhulu kwenkqubo.

2) Indlela yokulawula

Indlela yokulawula ungcoliseko lwebhayoloji inokufezekiswa ngokuqhubeka okanye ngokunqanda ukucoca kunye nokubulala iintsholongwane emanzini angenayo. Ukubulala inzala kunye nezixhobo zokulinganisa kufuneka zifakelwe amanzi akrwada aqokelelwe kumphezulu kunye nophantsi komhlaba ongekho nzulu, kwaye imichiza yokungunda iklorin kufuneka yongezwe. Idosi ngokuqhelekileyo isekelwe kumxholo weklorini oshiyekileyo kwimpembelelo ibe mkhulu kune-1mg/L.

Ukungacoceki kwemichiza

1) Izizathu zokubunjwa kwayo

Ezona zizathu zixhaphakileyo zongcoliseko lweekhemikhali kukubekwa kwesikali sekhabhoni ngaphakathi kumalungu e-membrane, okubangelwa ikakhulu kukungasebenzi kakuhle, inkqubo yokudosi ye-inhibitor engaphelelanga, kunye nokuphazamiseka kwesikali se-inhibitor dosing ngexesha lokusebenza. Ukuba ayibonwanga ngexesha elifanelekileyo, isenzeko sokunyuka koxinzelelo lokusebenza, ukuhluka koxinzelelo olwandisiweyo, kunye nokunciphisa izinga lokuvelisa amanzi kuya kwenzeka kwiintsuku ezimbalwa. Ukuba i-scaling inhibitor ekhethiweyo ayihambelani nomgangatho wamanzi okanye i-dosage ayanelanga, ukukala ngaphakathi kwe-membrane element kuya kwenzeka. Ukulinganisa okuphakathi ngaphakathi kwento ye-membrane kunokubuyiselwa emsebenzini wayo ngokucocwa kweekhemikhali, kwaye kwiimeko ezinzima, kunokubangela ukuba ezinye izinto ezingcolisekileyo ze-membrane zikhutshwe.

2) Indlela yokulawula

Indlela yokulawula ukuthintela ukukala ngaphakathi kwi-membrane element kukuqala ukhethe i-reverse osmosis scale inhibitor efanelekileyo yomgangatho womthombo wamanzi wenkqubo, kwaye umisele idosi efanelekileyo. Okwesibini, ukuqinisa ukubekwa esweni kwenkqubo yokudosa, ukubeka iliso ngononophelo utshintsho olufihlakeleyo kwiiparamitha zokusebenza, kwaye uchonge ngokukhawuleza unobangela wazo naziphi na izinto ezingaqhelekanga. Ukongeza, i-Fe3 + ephezulu emanzini ibangelwa kakhulu ziinkqubo zemibhobho. Ngoko ke, imibhobho yeplastiki enentsimbi kufuneka isetyenziswe kangangoko kwimibhobho yenkqubo, kubandakanywa nemibhobho yomthombo wamanzi, ukunciphisa umxholo we-Fe3+.

I-particle enqunyiweyo kunye nongcoliseko lwe-colloidal

1) Izizathu zokubunjwa kwayo

Amasuntswana axhonyiweyo kunye ne-colloids zizinto eziphambili ezivala ii-membrane ze-osmosis, kwaye zikwazona zizathu eziphambili zokugqithisa i-SDI yamanzi amdaka (i-sludge density index). Ngenxa yokungafani kwimithombo yamanzi kunye nemimandla, kukho ukuhluka okuphawulekayo ekubunjweni kweengqungquthela ezimisiweyo kunye ne-colloids. Izinto eziphambili zamanzi angaphezulu angangcoliswanga kunye namanzi aphantsi komhlaba angekho nzulu ziibhaktheriya, udongwe, i-silica ye-colloidal, i-iron oxides, iimveliso ze-humic acid, kunye negalelo eligqithisileyo le-coagulants kunye ne-coagulants (njengeetyuwa zentsimbi, iityuwa ze-aluminiyam, njl.) kwinkqubo yonyango. Ukongeza, imvula eyenziwe ngokudityaniswa kweepolima ezityalwayo ngokufanelekileyo kumanzi akrwada kunye nezithinteli zesikali esichasayo kwiinkqubo ze-osmosis ezibuyela umva ngomnye woonobangela bongcoliseko olunjalo.

2) Indlela yokulawula

Xa umxholo wezinto eziqinileyo ezimisiweyo kumanzi akrwada udlula i-70mg/L, i-coagulation, ingcaciso, kunye neendlela zokucoca kwangaphambili zisetyenziswa rhoqo; Xa umxholo wezinto eziqinileyo ezimisiweyo kumanzi akrwada ungaphantsi kwe-70mg/L, i-coagulation filtration idla ngokusetyenziselwa unyango lwangaphambili; Xa umxholo wezinto eziqinileyo ezimisiweyo kumanzi akrwada ungaphantsi kwe-10mg/L, indlela yokucoca ngokuthe ngqo idla ngokusetyenziswa. Ukongeza, i-microfiltration okanye i-ultrafiltration yindlela yonyango ye-membrane esebenzayo ye-turbidity kunye ne-insoluble organic matter evele kutshanje. Inokususa zonke izinto eziqinileyo ezimisiweyo, iibhaktheriya, uninzi lwe-colloids, kunye nezinto ezinganyibilikiyo zezinto eziphilayo, kwaye yinkqubo efanelekileyo yonyango lwangaphambili lweenkqubo ze-osmosis ezibuyela umva.
