Decomposition vs Combustion

Ob qho tib si decomposition thiab combustion yog cov txheej txheem tshuaj ntawm kev hloov cov khoom nyuaj rau hauv ntau cov tebchaw yooj yim dua.

Txhob Cia Siab

Decomposition yog txheej txheem ntuj. Thaum cov tsiaj txhu thiab cov nroj tsuag tuag thiab tso tawm, lawv lub cev thiab lwm yam khoom siv pov tseg tau tawg ua cov khoom me me thiab thaum kawg mus rau cov ntaub ntawv yooj yim dua. Cov txheej txheem no hu ua decomposition. Yog tias tsis yog rau txoj haujlwm no, tag nrho lub cev tuag yuav raug khaws cia rau hauv lub ntiaj teb, thiab yuav tsis muaj chaw rau cov kab mob tshiab. Yog li ntawd, decomposition yog ib qho tseem ceeb rau recycle qhov teeb meem kom tshem tawm qhov chaw hauv biome. Nyob rau hauv ib qho ecosystem, invertebrates zoo li earthworm, kab mob thiab fungi yog lub luag hauj lwm rau decomposing khoom. Lawv ua lub luag haujlwm tseem ceeb hauv cov saw zaub mov, los ntawm kev muab cov as-ham rau cov nroj tsuag los ntawm decomposing. Lub caij no, decomposers noj zaub mov rau lawv los ntawm kev rho tawm cov tshuaj los ntawm lub cev tuag thiab siv cov no los tsim lub zog. Thaum decomposers tuag thiab tso tawm, cov ntaub ntawv no kuj decompose. Yog li ntawd, qhov no yog lub voj voog ntawm cov khoom noj khoom haus ntws hauv ecosystems. Decomposition ntawm ib tug kab mob pib sai tom qab tuag, thiab nws undergoes ib theem ntawm cov theem, uas yog ib txwm rau txhua yam kab mob. Cov txheej txheem no muaj tsib theem xws li tshiab, bloat, active decay, advanced decay, thiab qhuav / seem nyob rau theem. Cov theem tshiab yog theem tom qab kev tuag ntawm cov kab mob. Cov dej num ib txwm tau nres, thiab lub cev maj mam txias. Txij li thaum cov pa oxygen nthuav tawm hauv lub cev sai sai, cov kab mob anaerobic pib loj hlob sai hauv lub cev. Hauv theem plab, qhov ua haujlwm anaerobic kab mob siab heev. Yog li ntawd, cov gases uas tsim los ntawm lawv cov txheej txheem yuav tsub zuj zuj nyob rau hauv lub cev tuag thiab muab ib tug bloated tsos. Nyob rau hauv lub active decay theem, lub cev loj hlob sai heev. Los ntawm theem kev lwj siab heev, cov kev ua kom lwj tau cuam tshuam loj heev. Thiab nyob rau theem kawg tsuas yog cov pob txha, pob txha mos thiab tawv nqaij. Cov qib siab ntawm cov as-ham yuav muaj nyob rau hauv cov av ib puag ncig ntawm qhov qhuav / seem.

Muaj ntau yam, uas ua rau tus nqi decomposition. Piv txwv li, cov khoom raug dej thiab huab cua yuav decompose sai dua li cov khoom uas tsis muaj dej thiab cua. Qhov kub thiab txias, qib oxygen, dej, nkag tau los ntawm scavengers, thiab qhov loj ntawm lub cev yog qee yam uas txiav txim siab tus nqi decomposition.

Combustion

Combustion yog ib qho tshuaj tiv thaiv exothermic, uas ua rau cua sov los ntawm cov tshuaj tiv thaiv ntawm cov roj thiab cov oxidant. Hauv cov txheej txheem no, cov khoom pib yuav raug hloov mus rau lwm hom kev sib txuas, thaum ua kom sov. Roj yuav ua tau hydrocarbons nyob rau hauv cov khoom, kua los yog gaseous daim ntawv. Feem ntau cov oxidant yog cov pa oxygen. Hauv hydrocarbon combustion, carbon dioxide thiab dej yog tsim los ua cov khoom tseem ceeb. Feem ntau thaum cov oxidant yog oxygen, cov khoom yog oxides ntawm cov ntsiab lus sib txawv nyob rau hauv cov roj. Cov tshuaj tiv thaiv combustion yog siv los tsim lub zog hauv lub cav tsheb thiab cov tshuab, rau kev ua noj, thiab lwm yam. Kev sib txuas tuaj yeem yog ob hom kev sib xyaw ua tiav thiab tsis tiav. Kev tawg tsis tiav tshwm sim thaum tsis muaj oxygen txaus. Qhov no yuav tsim ntau hom by-products thiab particulate teeb meem, uas ua rau ib puag ncig muaj kuab paug. Kev combustion tsis tiav, tsuas yog ib qho tsawg ntawm cov khoom yuav raug tsim.

Dab tsi yog qhov txawv ntawm Decomposition thiab combustion?

• Decomposition is a natural process. Tab sis combustion tuaj yeem yog ntuj lossis tib neeg pib txheej txheem.

• Decomposition yog ua los ntawm decomposers zoo li invertebrates, fungi thiab kab mob.

• Lub hom phiaj ntawm combustion yog tsim kom muaj zog. Qhov tseem ceeb ntawm kev decomposition yog rov ua dua cov khoom thiab muab cov as-ham thiab chaw rau cov kab mob tshiab.
