Phekolo ea metsi a litšila ka likokoana-hlokoke mokhoa o sebelisoang haholo oa likhoerekhoere lefatšeng. Theknoloji e sebelisa mefuta e fapaneng ea libaktheria le likokoana-hloko tse ling ho phekola le ho hloekisa metsi a silafetseng.
Tlhokomelo ea metsi a litšila e bohlokoa ka ho tšoanang bophelong ba batho le ho sireletsa tikoloho. Ha e le hantle, tšebeliso ea libaktheria tsena e potlakisa phekolo ea tšilafalo e nyenyane ea holim'a metsi: limela tsa decontamination. Sena se molemo ho feta ho lumella noka hore e sebetsane le eona, hobane le hoja e le mokhoa o tšoanang oa tlhoekiso o hlahang tlhahong, palo ea tšilafalo e hlahisoang kajeno e phahame haholo ho boloka potoloho ea tlhaho e ntse e le teng. Kahoo, limela tsa likhoerekhoere li thibela ho ata ha linōka hape li thibela ho ata ha mafu.
Metsi a litšila a masepala le a indasteri ke mehloli e meholo ea metsi a litšila. Ka lebaka la tšebeliso ealikokoana-hloko, re khona ho nyenyefatsa litaba tsa litšila tsena tsa tlhaho kaha li sebelisoa e le mohloli oa lijo le matla a ho hōla le

Libaktheria li bohareng ba ts'ebetso ena. Qetellong, setsi sa ho hloekisa likhoerekhoere ke polasi e hōlisang likokoana-hloko ka tekanyo e kholo.
Libaktheria li lula hokae?
Hohle, ho tloha metsing a fihlang setsing sa phekolo ho ea moo ho tsoang teng. Mekhahlelo ea ts'ebetso e behiloeng ka tanka ea phekolo e ama nts'etsopele ea mefuta e sa tšoaneng ea likokoana-hloko le mefuta e li etsang. Ho fapana le ts'ebeliso ea li-monocultures, sehlopha sena sa likokoana-hloko se ruisitsoe ka mefuta e mengata 'me se ka finyella maemo a phahameng a biodegradation holim'a mefuta e mengata ea substrates. Lena ke lona lebaka le ka sehloohong le amang boleng ba a

Ka tloaelo, likokoana-hloko tsena lia bokellana 'me li kopana ho ba lintho tse kang lakane tse bitsoang "flocs" ka setso sa mahala. Li-floe tsena tse kholo li na le lisele tse phelang le tse shoeleng tsa libaktheria, li-fungus, protozoa le metabolites. Li bokellana ho pota-pota lintho tse phelang tse fanyehiloeng tse jang ka tsona. Ho joalo, ka mohlala, ka li-slurries tse kentsoeng. Ho feta moo, litsong tse tsitsitseng, li-biofilms tse tšoanang li thehoa holim'a libaka tse hokahaneng. Mohlala, li-biofilters le li-biodisc ke litso tse tsitsitseng.
Limela tse ling li na le li-reactors tsa UV kapa ente ea khase ea chlorine ho felisa libaktheria tse ntseng li le teng metsing a tsoang pele a ntšetsoa ka linōkeng. Sena ke 'nete Australia le New Zealand.
Likokoana-hloko tsee ke bo-mang?
Taba ea pele, pele re utloisisa hore na ke bo-mang, re tlameha ho utloisisa maemo a amang kholo ea bona. Ntlha ea pele, sebaka sa libaka. Ea bobeli, mofuta oa letamo leo baktheria e hōlang ho lona. Ea boraro ke litšobotsi tsa metsi a litšila a kenang fekthering. Qetellong, likarolo tsa ts'ebetso ea sistimi, joalo ka aeration, agitation, ente ea lik'hemik'hale. Lintlha tsena kaofela li hlahisa phapang ea bongata lipakeng tsa autotrophic le heterotrophiclibaktheria.
Mocheso o ka ama boteng ba mefuta e itseng. Kahoo, phello ea sebaka sa libaka e ka ama sebopeho sa mefuta. Ka lehlakoreng le leng, mohlala, indastering, boteng ba likokoana-hloko tse hlalositsoeng hantle li ka hlalosoa ke bokhoni ba tsona ba ho senya likarolo tse itseng tsa metsi a litšila a indasteri.
Libaktheria li boetse li aroloa ho latela tsela eo li fumanang oksijene ka eona. Ho hloekisoa ha metsi a litšila, libaktheria tse sebelisoang ho hloekisa metsi a litšila tse kenang setsing sa ho hloekisa li arotsoe ka mefuta e meraro: baktheria ea aerobic, baktheria ea anaerobic le baktheria ea facultative.
