Peb qhov kev thov kom muaj dej tshiab tau nce mus rau qhov txo qis hauv nws cov peev txheej. Cov kws tshawb fawb tau sim nrhiav cov tswv yim los ntxuav cov dej huv kom rov siv tau kom tau raws li qhov xav tau yav tom ntej. Tam sim no, cov txheej txheem kho dej khib nyiab feem ntau cuam tshuam nrog kev siv tshuaj lom neeg lossisultraviolet hluav taws xobtua cov kab mob me me lossis tshem cov pa phem. Txawm li cas los xij, cov thev naus laus zis ib txwm muaj ob peb qhov tsis zoo, xws li cov tshuaj lom lom ntawm tshuaj lom neeg rau peb kev noj qab haus huv lossis lub zog siab xav tau ntawm cov chaw kho mob. Txhawm rau tsim cov txheej txheem kho cov dej khib nyiab kom ruaj khov, lub hom phiaj tau hloov mus rau ib puag ncig tus phooj ywg thiab thev naus laus zis tsim txiaj.
Ib qho xws li thev naus laus zis tau tshawb fawb cuam tshuam nrog kev siv cov kab mob hauv dej, xws li algae, uas paub tias ua rau cov txheej txheem nyuaj. Tsis ntev los no, ib pawg kws tshawb fawb los ntawm Is Nrias teb (kev tshawb fawb algae thiab bioenergy Laboratory ntawm Northern University; Lub Tsev Kawm Ntawv ntawm Kev Tshawb Fawb thiab Biotechnology ntawm sholini University; thiab Biotechnology Department of Korean dolphin (PG) Institute of biomedical and Natural Sciences) (Department of environmental engineering, Seoul University) thiab Russia (Lub koom haum sib koom ua haujlwm siab ntawm Lavxias Academy ntawm Kev Tshawb Fawb thiab Lub Chaw Saib Xyuas ib puag ncig thiab kev kwv yees ntawm RUDN University), coj los ntawm Dr. Pankaj Kumar chauhan ntawm shoolini University hauv Is Nrias teb, tsim cov txheej txheem kho dej khib nyiab raws li algae bioremediation. Lawv cov kev tshawb fawb tau tshaj tawm hauv kev tshawb fawb ib puag ncig.
Algae siv nitrogen, carbon, phosphorus lossis hnyav hlau hauv dej ua cov as -ham kom npog cov dej hauv lub cev nrog zaj duab xis ntsuab lossis ua rau dej ntws liab. Ib qho loj ntawm cov algae hauv dej yuav sib tw nrog lwm cov kab mob me me rau cov as -ham thiab tshav ntuj, yog li txhawm rau txo tus naj npawb ntawm cov kab mob hauv dej. Nov yog qee qhov yam ntxwv uas ua rau algae dhau los ua cov dej ntxuav cov dej huv. Ib qho ntxiv, lawv yog tus phooj ywg ib puag ncig thiab muaj tus kheej uas yog cov neeg ua haujlwm kho cov dej pov tseg Kev saib xyuas thiab tus yam ntxwv tsim txiaj ntsig.
Dr. chauhan piav qhia lub hauv paus txheej txheem ntawm nws pab neeg' txoj kev txhim kho:" Peb tau xaiv cov kab mob microalgae tshiab pseudochlorella pringsheimii vim tias nws tuaj yeem tiv taus cov pa phem ntau thiab loj hlob thoob qhov kub thiab txias. Ib qho ntxiv, pseudochlorella tau paub los ua kom muaj cov lipids ntau hauv nws cov cell hauv qab siab, uas qhib qhov muaj peev xwm siv cov algal biomass no rau kev sib xyaw roj.
Hauv lawv qhov kev sim, cov kws tshawb fawb tau sau pseudochlorella pringsheimii microalgae cov kab mob los ntawm cov pas dej ntuj thiab coj lawv mus rau hauv cov pob zeb dag uas muaj cov dej hauv lub nroog nyoos uas muaj ntau cov pa phem hnyav hlau thiab cov tshuaj tua kab mob tiv thaiv kab mob. Tom qab 14 hnub ntawm kev coj noj coj ua, lawv ntsuas peb qhov ntsuas hauv cov tso tsheb hlau luam no: cov dej zoo, kev loj hlob thiab cov tshuaj lom neeg muaj pes tsawg leeg ntawm P. pringsheimii. Lawv Lawv tseem txheeb xyuas qhov ua tau ntawm kev siv microalgae dej kho rau ntses kab lis kev cai.
Cov txiaj ntsig ntawm txoj kev tshawb fawb no tau txhawb nqa heev. P. pringsheimii kev cog qoob loo tau txhim kho cov dej zoo los ntawm kev tshem cov hlau hnyav thiab cov kab mob phem. Dr. Johan tau piav qhia zoo siab tias tom qab kho tas, peb pom cov tshuaj oxygen xav tau (COD) Cov qib ntsuas dej muaj kuab paug xws li, alkalinity thiab tawv tawv tau txo los ntawm 83.2%, 66.7% thiab 69.6% feem. Ib qho ntxiv, kev loj hlob ntawm algae yuav luag tshem tawm tag nrho cov kab mob thiab coliforms hauv dej. Peb kuj pom tias lipid cov ntsiab lus hauv algae biomass loj hlob hauv cov dej khib nyiab tau nce ntau dua piv nrog cov algae cog hauv nruab nrab tswj. Qhov no txhais tau tias cov algae no tuaj yeem rov ua dua tshiab rau kev sib xyaw roj av.
Ib qho ntxiv, txawm hais tias tsis muaj cov ntses nqus tau muaj sia nyob hauv cov dej khib nyiab qub, 84% ntawm cov dej khib nyiab kho tsis tsuas yog muaj txoj sia nyob ntev dua 10 hnub, tab sis kuj ua rau lawv lub cev hnyav li 47%.
Yog li no, thev naus laus zis tshiab no tau ua tiav qhov ua tau zoo hauv kev tshawb fawb txog kev kho cov dej khib nyiab ib puag ncig, thiab hais txog qhov siv tau cov dej kho rau cov kab lis kev cai ntses qis. Dr. chauhan vam tias lawv cov microalgae raws li bioremediation thev naus laus zis yuav ua rau txoj hauv kev ntsuab dua thiab muaj kev nyab xeeb yav tom ntej.
