Surfactants ib txwm muaj tau tsim los ntawm tib neeg thiab tuaj yeem tsim kev puas tsuaj rau ib puag ncig, tshwj xeeb tshaj yog dej ecosystems. Hauv kev sib zog los txo qhov kev cuam tshuam tsis zoo no, cov kws tshawb fawb tau tsim cov biodegradable surfactants.
Cov surfactants cuam tshuam li cas rau ib puag ncig?
Nws tau txiav txim siab tias lub luag haujlwm ntawm anionic surfactants nyob rau hauv ib puag ncig yog tsis meej: lawv tuaj yeem ua rau muaj kuab paug ib puag ncig loj nrog cov tshuaj lom rau cov kab mob nyob; txwv tsis pub, lawv tuaj yeem txhawb qhov kev puas tsuaj thiab / lossis tshem tawm lwm yam tsis zoo thiab cov organic ua paug los ntawm ib puag ncig.
Dab tsi yog qhov phem ntawm surfactants?
Ntau tus surfactant uas muaj cov dej khib nyiab pov tseg rau hauv ib puag ncig, ua rau ua phem rau lub neej hauv dej, ua paug dej thiab ua rau tib neeg noj qab haus huv. Yog li ntawd, nws yog ib qho tseem ceeb los saib xyuas thiab tswj emissions ntawm surfactants nyob rau hauv ib puag ncig dej.
Dab tsi surfactants yog biodegradable?
Qhov kawg degradation tau hais tias tau tshwm sim thaum lub surfactant molecule tau muab rau CO2, CH4, dej, ntxhia ntsev thiab biomass. LAS feem ntau suav tias yog biodegradable surfactants. Cov qib biodegradation siab heev (97–99%) tau pom hauv qee qhov WWTP siv cov txheej txheem aerobic [7], [8], [9].
Yuav ua li cas surfactants biodegrade?
Kev tshuaj ntsuam ntawm kev tshuaj ntsuam-kev ntsuam xyuas qhia tau hais tias rau txhua qhov kev sim ntsuas cov roj-cawv ethoxylates, muaj qhov kev nyiam tshaj plaws surfactant biodegradation ntawm surfactant nrog ntev alkyl saw thiab siab dua. Qib ntawm ethoxylation.

Kev ua phem ua qias puas cuam tshuam rau ib puag ncig?
Kev ua phem ua qias tuaj yeem cuam tshuam rau ib puag ncig los ntawm ua rau qee hom tsiajNws ua rau cov tsiaj txhu uas raug kev puas tsuaj mus rau qhov kawg, yog li tsim kev cuam tshuam hauv cov saw hlau. Thaum kawg, nws yuav ua rau muaj kev hloov pauv tshiab ntawm cov tsiaj, thiab/lossis hom dhau ntawm tib neeg kev tswj hwm .
Puas yog cov steamboats phem rau ib puag ncig?
Pib nrog, lub nkoj ua haujlwm hloov pauv ib puag ncig nyob rau sab hnub poobSteamboats xav tau cov ntoo loj heev rau roj. … Cov neeg nyob ntawm tus dej yuav txiav ntoo thiab muab lawv tso rau ntawm ntug dej thiab tau txais cov nyiaj them los ntawm cov neeg tsav nkoj rau lawv cov khoom .
Cov roj teeb lithium puas phem rau ib puag ncig?
Kev cuam tshuam ib puag ncig Lithium-ion roj teeb muaj cov hlau tsis muaj tshuaj lom ntau dua li lwm cov roj teeb uas tuaj yeem muaj cov hlau toxic xws li txhuas lossis cadmium, lawv feem ntau suav tias yog tsis muaj kev phom sij . Puas yog lithium roj teeb muaj kev ruaj ntseg?
Puas yog aerosols phem rau ib puag ncig?
Tsis muaj teeb meem cuam tshuam ntawm ib puag ncig Feem ntau, txhua lub aerosols muaj cov tshuaj sib txuas uas nyob rau hauv ib txoj kev los yog lwm qhov, muaj kev phom sij rau ib puag ncig. Cov tshuaj lom neeg los ntawm aerosols yog tshuaj lom thaum lawv paug dej, av, thiab lwm yam ntuj tsim .
Puas foob pob hluav taws phem rau ib puag ncig?
Ib tus kws tshawb fawb tau hais rau Forbes tias thaum lub foob pob hluav taws tawm mus, cov hlau ntsev thiab cov khoom tawg tau raug tshuaj lom neeg cov tshuaj tiv thaiv uas tso pa taws thiab pa tawm rau saum huab cua. Qhov ntawd suav nrog cov pa roj carbon dioxide, carbon monoxide, thiab nitrogen-peb lub tsev cog khoom roj uas hmoov tsis muaj lub luag haujlwm rau kev hloov pauv huab cua Pob foob pob hluav taws ntxiv rau lub ntiaj teb ua kom sov?
