Qhov sib txawv tseem ceeb ntawm cheeb tsam ntawm aeration thiab cheeb tsam ntawm saturation yog tias cheeb tsam ntawm aeration nyob nruab nrab ntawm lub ntiaj teb saum npoo av thiab dej rooj thaum thaj tsam ntawm saturation nyob hauv qab lub rooj dej saturated nrog dej.
Cov dej hauv av uas tau nkag mus rau hauv lub ntiaj teb saum npoo yog pom nyob rau hauv ob txheej av. Lawv yog thaj tsam ntawm aeration thiab cheeb tsam ntawm saturation. Lub rooj dej ua raws li ciam teb ntawm ob txheej no. Raws li tus nqi ntawm cov dej hauv av hloov pauv, lub rooj dej nce thiab poob raws li. Cov dej uas muaj peev xwm tuav tau hauv av yog hu ua porosity. Tus nqi ntawm cov dej ntws los ntawm cov av yog permeability. Qhov chaw aeration thiab saturation zone tuav cov dej sib txawv thiab nqus dej sib txawv.
Zone of Aeration (Unsaturated Zone) yog dab tsi?
Thaj chaw ntawm aeration yog thaj av uas nyob nruab nrab ntawm lub ntiaj teb saum npoo av thiab lub rooj dej. Cov khoom tseem ceeb ntawm thaj chaw aeration yog av thiab pob zeb. Lub cheeb tsam ntawm aeration tseem hu ua thaj chaw unsaturated. Cov pores nyob rau hauv cheeb tsam no feem ntau yog ntim nrog huab cua thiab dej. Aeration tshwm sim thaum huab cua thiab dej los ze zog. Lub xub ntiag ntawm huab cua thiab dej ua rau muaj kev tsim cov av noo. Huab cua qhia tias muaj oxygen, uas cuam tshuam tus nqi ntawm corrosion ntawm cov khoom hlau faus hauv av.
Daim duab 01: Thaj Chaw ntawm Aeration thiab Zone ntawm Saturation
Qhov muaj pes tsawg leeg thiab qhov tob ntawm thaj chaw no txawv ntawm ib cheeb tsam mus rau lwm qhov. Qhov ntawd cuam tshuam los ntawm yam xws li qhov siab, hom av thiab cov qauv, hom pob zeb, kev nyab xeeb, tib neeg kev ua ub no, toj roob hauv pes, thiab nroj tsuag. Cov dej hauv av hauv thaj tsam ntawm aeration yog los ntawm ntau qhov chaw, xws li infiltration ntawm cov dej saum npoo av los ntawm cov nag, dej ntws, thiab cov dej khib nyiab thiab cov nyhuv capillary ntawm cov dej los ntawm thaj tsam ntawm cov dej hauv qab rooj dej. Qhov no tseem cuam tshuam rau cov dej noo hauv thaj tsam ntawm aeration vim qhov hloov pauv ntawm huab cua thiab dej cuam tshuam rau oxygen. Yog li ntawd, tus nqi ntawm corrosion nyob rau hauv cov khoom hlau nce nrog cov ntsiab lus oxygen. Tej yam xws li lwm yam ntaub ntawv nyob rau hauv cov av, muaj ntau yam hlau, impurities nyob rau hauv dej kuj muaj feem xyuam rau tus nqi ntawm corrosion nyob rau hauv faus cov khoom nyob rau hauv lub cheeb tsam ntawm aeration.
Zoo ntawm Saturation (Phreatic Zone) yog dab tsi?
Thaj chaw saturation yog thaj av tam sim ntawd hauv qab lub rooj dej. Nws tseem hu ua thaj tsam phreatic. Hauv cheeb tsam no, cov pores yog saturated nrog dej tab sis kuj muaj cov av thiab pob zeb. Lub cheeb tsam ntawm saturation yog tsawg corrosive, thiab cov ntsiab lus noo noo nyob rau hauv cheeb tsam no yog nyob rau ntawm ib tug huab. Yog li ntawd, qhov siab tshaj plaws corrosion tshwm sim nyob rau hauv nruab nrab ntawm ob qho kawg. Cov cheeb tsam ntawm saturation feem ntau pom nyob nruab nrab ntawm ob peb taw thiab ntau txhiab ko taw hauv qab lub ntiaj teb saum npoo av.
Cov dej haus feem ntau muaj nyob hauv thaj av no thaum muaj dej ntws, qhov dej, thiab qhov dej. Cov dej no muaj kuab paug los ntawm tib neeg kev ua ub no xws li kev siv tshuaj chiv, tshuaj tua kab, pov tseg, thiab septic tanks. Qhov tob thiab qhov loj ntawm cheeb tsam no nyob ntawm qhov hloov raws caij nyoog. Yog li ntawd, theem ntawm cheeb tsam nyob ntawm seb nws yog lub sijhawm qhuav lossis ntub dej. Lwm yam xws li tib neeg kev ua ub no thiab kev nqus dej los ntawm qhov dej, qhov dej, thiab cov dej ntws kuj cuam tshuam rau qhov tob thiab qhov loj. Qhov qis corrosive cua yog tshwm sim los ntawm qhov tsis tshua muaj siab ntawm oxygen hauv cov av. Tab sis yam xws li yaj ions xws li chloride ions, sulphates, thiab lwm yam aggressive tshuaj cuam tshuam rau corrosion nyob rau hauv cheeb tsam ntawm saturation.
Dab tsi zoo sib xws ntawm Zone ntawm Aeration thiab Zone ntawm Saturation?
- Zone of aeration and azone of saturation is on the ground.
- Lawv muaj av thiab pob zeb.
- Lawv tuaj yeem cuam tshuam los ntawm tib neeg kev ua haujlwm thiab huab cua.
- Zone ntawm aeration thiab saturation muaj dej.
Dab tsi yog qhov txawv ntawm Zone ntawm Aeration thiab Zone ntawm Saturation?
Zone ntawm aeration muaj cov txheej txheej sab saud ntawm cov av uas muaj huab cua puv qhov hws lossis cov hnab ntim cua tsis muaj dej. Thaj chaw ntawm saturation muaj cov pores thiab pob txha tawg uas saturated nrog dej. Yog li, qhov no yog qhov sib txawv tseem ceeb ntawm cheeb tsam ntawm aeration thiab cheeb tsam ntawm saturation. Tsis tas li ntawd, thaj tsam ntawm aeration muaj cov pa oxygen ntau, yog li lawv yooj yim dua rau corrode cov khoom faus hauv av. Meanwhile, thaj tsam ntawm saturation yog tsawg corrosive tshaj qhov unsaturated cheeb tsam vim cov dej noo thiab oxygen nyob rau hauv cov av yog tsawg.
Cov hauv qab no infographic nthuav tawm qhov sib txawv ntawm cheeb tsam ntawm aeration thiab cheeb tsam ntawm saturation hauv daim ntawv tabular rau ib sab ntawm kev sib piv.
Summary – Zone of Aeration vs Zone of Saturation
Zone ntawm aeration thiab cheeb tsam ntawm saturation yog ob txheej ntawm lub ntiaj teb nto. Lub cheeb tsam ntawm aeration yog nyob nruab nrab ntawm lub ntiaj teb nto thiab lub rooj dej. Zone ntawm saturation nyob hauv qab lub rooj dej. Cov pores nyob rau hauv cheeb tsam ntawm aeration feem ntau yog ntim nrog huab cua thiab dej. Aeration tshwm sim thaum huab cua thiab dej los ze zog. Vim muaj dej thiab huab cua, muaj cov dej noo ntau. Yog li ntawd, nws muaj peev xwm corrode cov khoom yooj yim. Nyob rau hauv cheeb tsam ntawm saturation, pores yog saturated nrog dej tab sis kuj muaj xws li av thiab pob zeb. Cov dej haus feem ntau yog tuav hauv cheeb tsam no. Qhov chaw uas tsis muaj corrosive yog qhov tshwm sim ntawm qhov tsis tshua muaj oxygen hauv cov av hauv cheeb tsam no. Yog li, qhov no qhia txog qhov sib txawv ntawm cheeb tsam ntawm aeration thiab cheeb tsam ntawm saturation.
