Ts'ebetsong ea metsi a litšila, ho lekola meroalo ea lintho tse phelang, haholoholo Total Organic Carbon (TOC), e se e le bohlokoa ho boloka ts'ebetso e sebetsang hantle le e sebetsang. Sena ke 'nete haholo liindastering tse nang le melapo ea litšila e fapaneng haholo, joalo ka lekala la lijo le lino (F&B).
Puisanong ena, Jens Neubauer le Christian Kuijlaars ba tsoang Veolia Water Technologies & Solutions ba buisana le AZoMaterials ka bohlokoa ba ho beha leihlo TOC le kamoo tsoelo-pele ea theknoloji ea TOC e fetolang mekhoa ea ho hloekisa metsi a litšila.
Hobaneng ho lekola meroalo ea lintho tse phelang, haholo Total Organic Carbon (TOC), ho le bohlokoa ho hloekisoeng ha metsi a litšila?
Jens: Metsing a mangata a litšila, boholo ba litšila ke tsa tlhaho, 'me sena ke 'nete haholo bakeng sa lekala la F&B. Ka hona, mosebetsi o ka sehloohong oa setsi sa ho hloekisa likhoerekhoere ke ho qhaqha lintho tsena tse phelang le ho li ntša metsing a litšila. Ho matlafatsa ts'ebetso ho etsa hore ho hloekisa metsi a litšila ka potlako le ho sebetsa hantle. Sena se hloka tlhokomelo e sa khaotseng ea motsoako oa metsi a litšila ho rarolla ka potlako liphetoho leha e le life, ho etsa bonnete ba ho hloekisa ka katleho ho sa tsotellehe nako e khutšoanyane ea phekolo.
Mekhoa e tloaelehileng ea ho lekanya litšila tse phelang metsing, joalo ka tlhokahalo ea oksijene ea lik'hemik'hale (COD) le liteko tsa biochemical oxygen demand (BOD), li lieha haholo - li nka lihora ho fihlela matsatsi - li etsa hore li se ke tsa tšoanela mekhoa ea kajeno ea phekolo e potlakileng. COD e ne e boetse e hloka li-reagents tse chefo, tse sa rateheng. Ha ho bapisoa, tlhahlobo ea mojaro oa organic e sebelisang tlhahlobo ea TOC e nka metsotso e seng mekae feela mme ha e kenyelle li-reagents tse chefo. E loketse hantle bakeng sa tlhahlobo ea ts'ebetso hape e fana ka liphetho tse nepahetseng haholoanyane. Phetoho ena e lebisang ho tekanyo ea TOC e boetse e bonahala ho litekanyetso tsa morao-rao tsa EU mabapi le taolo ea ho ntša metsi, moo tekanyo ea TOC e leng mokhoa o ratoang. Komisi ea Phethahatso ea Qeto (EU) 2016/902 e thehile liqeto tse molemo ka ho fetisisa tse fumanehang (BAT) tlas'a Directive 2010/75/EU bakeng sa mekhoa e tloaelehileng ea ho hloekisa / tsamaiso ea metsi a litšila lekaleng la lik'hemik'hale. Liqeto tse latelang tsa BAT le tsona li ka buuoa ka taba ena.
Tekolo ea TOC e phetha karolo efe ho boloka ts'ebetso le ts'ebetso ea lits'ebetso tsa ho hloekisa metsi a litšila?
Jens: Tlhokomelo ea TOC e fana ka leseli la bohlokoa mabapi le phallo ea khabone libakeng tse fapaneng ts'ebetsong.
Ho beha TOC leihlo pele ho kalafo ea baeloji ho e lumella ho bona litšitiso tsa phallo ea khabone le ho e khelosetsa ho litanka tsa buffer kamoo ho hlokahalang. Sena se ka qoba ho jarisa baeloji le ho e khutlisetsa tšebetsong hamorao, ho lumella ho sebetsa ka mokhoa o sireletsehileng le o tsitsitseng oa semela. Ho lekanya TOC pele le ka mor'a mohato oa ho lokisa ho boetse ho lumella basebetsi ho laola coagulant dosing ka ho ntlafatsa ho eketsa carbon e le hore ba se ke ba lapa kapa ba fepa libaktheria ka har'a litanka tsa aeration le / kapa nakong ea mekhahlelo ea anoxic.
Tlhokomelo ea TOC e fana ka tlhahisoleseling mabapi le maemo a khabone sebakeng sa ho tsoa le katleho ea ho tlosa. Ho beha leihlo TOC ka mor'a sedimentation ea bobeli ho fana ka litekanyo tsa nako ea 'nete tsa khabone e lokollotsoeng tikolohong le ho paka hore meeli e fihletsoe. Ho feta moo, tlhahlobo ea lintho tse phelang e fana ka tlhahisoleseling mabapi le maemo a khabone ho ntlafatsa kalafo ea thuto e phahameng molemong oa tšebeliso hape 'me e ka thusa ho ntlafatsa tekanyetso ea lik'hemik'hale, kalafo ea pele ho membrane, le ozone le dosing ea UV.
