Nrog rau kev txwv tsis pub siv cov khoom yas pov tseg, ntau thiab ntau lub tuam txhab thiab cov neeg siv khoom tau tig lawv lub ntsej muag rau ib puag ncig hnub qub - cov ntaub ntawv biodegradable.
Peb txhua tus paub txog cov pa phem yas, hu ua "dawb paug", vim tias ntau cov khoom yas yog dawb thiab tuaj yeem muaj nyob hauv av tau ntau pua xyoo, ua rau cov av, dej, thiab huab cua phem heev, yog li lawv muab pov tseg.
Tab sis koj paub ntau npaum li cas txog cov ntaub ntawv biodegradable? Lub hauv paus ntsiab lus ntawm biodegradation yog dab tsi? Niaj hnub no, peb yuav kawm zaj dab neeg tom qab biodegradable cov ntaub ntawv ua ke.
Raws li kev tshawb fawb thev naus laus zis, lub hauv paus ntsiab lus ntawm biodegradation feem ntau cuam tshuam nrog ob txheej txheem.
Thawj kauj ruam yog kom decompose cov khoom biodegradable rau hauv me me nyob rau hauv ib puag ncig ntuj, thiab hydrolytic enzymes secreted los ntawm cov kab mob ua ke nrog rau saum npoo ntawm cov khoom me me degradable los hydrolyze cov saw hlau rau hauv cov khoom me me molecular, xws li cov organic acids. , qab zib, thiab lwm yam.
Hauv qhov thib ob, cov khoom sib xyaw me me tau nkag mus rau hauv lub cev los ntawm cov kab mob, metabolized thiab hloov mus rau hauv cov khoom hauv cov kab mob los yog lub zog rau cov kab mob microbial, thiab thaum kawg hloov mus rau carbon dioxide thiab dej, uas tau tawm ntawm lub cev. Cov pa roj carbon dioxide thiab dej tuaj yeem dhau los ua cov khoom noj uas xav tau los ntawm cov nroj tsuag, pab cov ecosystems tswj lub voj voog tsim txiaj thiab ua tiav cov hom phiaj tiv thaiv ib puag ncig.
