Qhov cuam tshuam ntawm cov ntaub ntawv ntim rau ntawm ib puag ncig thiab cov peev txheej
Cov ntaub ntawv yog lub hauv paus thiab forerunner ntawm kev lag luam hauv tebchaws thiab kev sib raug zoo. Nyob rau hauv cov txheej txheem ntawm cov khoom sau qoob, extraction, kev tsim khoom, kev thauj khoom, nws txhawb nqa kev sib raug zoo thiab kev nce qib ntawm tib neeg kev vam meej, ntawm qhov tod tes. Nws tseem yuav noj ntau lub zog thiab peev txheej, thiab tso tawm ntau cov roj pov tseg, khib nyiab dej thiab khib nyiab nyob rau tib neeg. Ntau cov ntaub ntawv txheeb cais qhia tau tias, los ntawm kev tsom xam tus txheeb ze lub zog ntawm lub zog thiab kev tsim khoom noj thiab cov khoom lag luam yog noj ib puag ncig, kev siv hluav taws xob ntau thiab txawm tias qhov chaw ua haujlwm. Nrog txoj kev vam meej ntawm cov khoom lag luam thiab nce siab heev ntawm kev lag luam ntim khoom siv, ntim cov ntaub ntawv tseem ntsib tib qho teeb meem. Raws li cov txheeb cais tsis tiav, tam sim no rau kev noj cov khoom ntim hauv lub ntiaj teb yog 145Kg ib xyoos. Ntawm 600 lab tons ntawm cov kua thiab cov khib nyiab tsim nyob hauv lub ntiaj teb txhua xyoo, ntim ntaub pua chaw yog li 16 lab tons, suav nyiaj rau 25% ntawm cov chaw hauv nroog pov tseg. 15% ntawm qhov loj. Nws yog conceivable hais tias tus lej zoo heev yuav ua rau ib puag ncig kev muaj kuab paug thiab pov tseg ntawm cov khoom siv hauv kev khiav ntev. Tshwj xeeb, cov kuab paug dawb "tshwm sim los ntawm cov ntaub ntim ntaub ntim ntaub pua ntxiv uas tsis tuaj yeem pom zoo 200 txog 400 xyoo yog pom tseeb thiab txhawj xeeb.

Qhov cuam tshuam ntawm cov ntaub ntawv ntim ntim rau ntawm ib puag ncig thiab cov kev pab cuam hauv peb yam.
(1) kev ua qias tuaj tshwm sim los ntawm cov txheej txheem ntau lawm ntawm cov khoom ntim
Hauv kev tsim cov khoom ntim, qee cov ntaub ntawv raw tau ua tiav rau cov ntaub ntawv ntim khoom, thiab qee cov khoom siv nyoos ua kuab paug thiab raug tso tawm rau hauv ib puag ncig. Piv txwv li, cov dej khib nyiab pov tseg, khib nyiab khib nyiab, khib nyiab tsis zoo thiab cov khoom muaj kuab, ua rau muaj kev phom sij, ua rau muaj kev phom sij rau ib puag ncig ib puag ncig.

(2) Qhov tsis muaj qab ntawm cov khoom ntim ntim nws tus kheej ua rau muaj kuab paug
Ntim ntaub ntawv (suav nrog kev zam tshwj xeeb) yuav ua rau cov ntsiab lus lossis ib puag ncig vim kev hloov pauv ntawm lawv cov tshuaj lom neeg. Piv txwv li, polyvinyl chloride (PVC) muaj kev txom nyem thermal stability. Nyob rau ntawm ib qho kub (txog 14 ° c), hydrogen thiab toxic chlorine yuav muaj decomposed, uas yuav ua rau cov ntsiab lus (ntau lub teb chaws txwv tsis pub dhau khoom noj). Thaum hlawv tshuaj chloride (HCI) yog tsim tawm, ua rau muaj cov kua qaub. Yog tias cov nplaum siv rau kev ntim khoom yog cov kuab tshuaj, nws tseem yuav ua kom muaj kuab paug vim nws cov kuab lom. Cov chlorofluorocarbon (CFC) siv rau kev lag luam ntim khoom siv ntau yam kev ua npuas dej yog cov khoom siv ua npuas dej loj yog cov khoom siv hluav taws xob ntau hauv ntiaj teb, nqa cov kev puas tsuaj loj rau tib neeg.

(3) Cov khib nyiab ntawm cov khoom ntim khoom ua rau muaj kuab paug
Ntim khoom yog feem ntau ib zaug siv, thiab txog 80% ntawm cov khoom ntim ntau ntawm cov khoom pov tseg. Los ntawm kev pom thoob ntiaj teb, cov khoom pov tseg tau tsim los ntawm cov ntim khoom khib nyiab rau txog li 1/3 ntawm qhov zoo ntawm Urban cov khoom khib nyiab. Cov ntaub ntawv ntim ntim ua rau cov khoom pov tseg loj, thiab ntau qhov tsis muaj kuab lom, tshwj xeeb yog cov khoom siv hluav taws xob ib puag ncig, tshwj xeeb yog cov yas ua npuas dej thiab cov yas pov tseg. Qhov "dawb paug" tsim los ntawm cov hnab yuav khoom yog qhov qias neeg loj tshaj plaws rau ib puag ncig.
