Cov rov ua dua tshiab yog cov txheej txheem physiochemical lossis mechanical nrog uas a teeb meem twb tau siv dhau qhov kev kho mob uas tso cai kom tau txais qhov tshiab raw khoom lossis khoom tshiab.
Ua tsaug rau kev rov ua dua tshiab, kev tsis siv cov ntaub ntawv uas tuaj yeem muaj txiaj ntsig zoo yog tiv thaiv, tib lub sijhawm uas kev siv cov khoom siv raw tshiab raug txo qis thaum cov khoom lag luam tshiab tuaj yeem tau txais. Ua li no, kev tsim cov khib nyiab hauv ntiaj teb raug txo ob txoj hauv kev thaum cov txheej txheem rov ua dua tshiab tiav.
Keeb kwm ntawm kev rov ua dua tshiab
Lub hauv paus pib ntawm kev rov ua dua tshiab rov qab tau ntau xyoo BC, raws li qhov uas thoob khib nyiab Nws tau muaj los ntawm lub sijhawm uas tib neeg tau tshwm sim nyob rau ntiaj chaw: txij li thawj haiv neeg kev vam meej nws yog qhov pov tseg ntawm cov khib nyiab tau ua teeb meem uas tau nce zuj zus.
Tsis ntseeg, ib lub sijhawm uas hloov pauv keeb kwm ntawm kev rov ua dua tshiab yog Kev Lag Luam Kev Lag Luam, lub sijhawm thaum tsim khoom tshiab khoom, tso cai rau ntau lub tuam txhab kom tsim cov khoom lawv thawj zaug.
Txawm li cas los xij, kev nyuaj nyiaj txiag tshwm sim los ntawm kev kub ntxhov xyoo 1929, thiab tom qab ntawd Tsov Rog Ntiaj Teb Zaum Ob, txhais tau tias cov nyiaj pov tseg tau txwv rau qhov tsawg kawg nkaus, uas tau txo qis mus txog rau xyoo 1970: thaum lub sijhawm ntawd cov pej xeem nyiam pib siv dua tshiab, thiab ntsuas los txhawb txoj kev xyaum no.

Neeg kho tshuab thiab qhov chaw rov ua dua tshiab
Kev rov ua dua tshiab yog qhov tseem ceeb hauv kev lag luam thiab kev lag luam, nrog rau hauv ib puag ncig hauv tsev. Kev nthuav dav thoob plaws feem ntau yog cov khoom siv rov ua dua tshiab, txheej txheem lub cev los ntawm cov ntsiab lus xws li yas Lawv tau rov qab siv tom qab.
Txawm li cas los xij, tseem muaj rov ua dua tshiab ntawm qhov chaw, uas yog koom nrog kev tshawb fawb, kev txhim kho thiab tsim khoom ntawm cov khoom siv tsawg dua txhais tau tias: los ntawm kev siv cov khoom siv raw tsawg dua, pov tseg tsawg dua thiab tsim cov peev txheej zoo dua.
Khib nyiab sib cais
Ib qho tseem ceeb ntawm kev rov ua dua tshiab yog pov tseg sib cais, txog qhov uas tsis yog txhua yam khoom tsim nyog sib npaug los ntsib qhov txheej txheem rov tsim dua tshiab: lawv raug hu cov khoom siv rov ua dua tshiab rau cov neeg uas ua tau rov siv dua.
Hauv qhov kev nkag siab no, kev nthuav dav cais kev cais cov khib nyiab yog qhov tseem ceeb uas yuav tsum tau ua los ntawm cov pej xeem, uas qhov sib txawv tau ua los ntawm cov xim ntawm lub ntim: xiav feem ntau yog npaj rau ntawv thiab duab los qhia, daj rau yas thiab cov kaus poom, ntsuab rau iav, liab rau pov tseg pov tseg, txiv kab ntxwv rau organic pov tseg, thiab grey rau qhov seem ntawm qhov seem uas tsis yog ntawm cov pab pawg ntawd.
