Lub ntiaj teb yog qhov tseem ceeb tshaj plaws rau peb kom peb dim. Yuav ua li cas tiv thaiv lub ntiaj teb ib puag ncig yeej ib txwm yog ib feem tseem ceeb ntawm kev tshawb fawb tib neeg. Environmental testing laboratories kuj tsim ntau cov kuab tshuaj nyob rau hauv tus txheej txheem ntawm kev pom thiab tsom, thiab ntau lub cheeb tsam muaj Tag nrho hom kev soj ntsuam, tiam sis, muaj cov ua kua uas tsim cov pa phem. Ua li cas hom kev phom sij puas muaj thiab seb cov kua qaub puas tau hloov lawm? Koj puas tau kawm txog cov teeb meem no?
Feem ntau cov pa phem nyob hauv chaw kuaj kab mob hauv tsev yog cov dej khib nyiab, khib nyiab, thiab cov seem pov tseg. Txawm li cas los xij, peb tuaj yeem faib lawv raws li cov huab cua phem: tshuaj lom neeg ua paug, ua paug lom neeg, thiab cov kab mob kis tsis huv. Raws li daim ntawv ntawm cov kuab paug: Cov dej khib nyiab, nkev roj, khib nyiab
Tsis tas li ntawd, nyob rau hauv qhov kev ntsuam xyuas ib puag ncig, kev sim kev qias neeg ntawm nws qhov project yog tshwj xeeb heev. Cov nram qab no Xiaobian ntawm BOKA qhia nws mus rau ib qhov teeb meem no:
Kev soj ntsuam ntawm cov dej khib nyiab feem ntau ntawm Cl - (feem ntau cov luam ntawv thiab dyeing wastewaters muaj Cl-), 0.4 g ntawm HgSO4 yuav tsum muab ntxiv rau tshem tawm Cl - interference . Yog tias koj tsis suav cov kab ntau los sis hnoos thiab tsuas siv ib qho qauv dej xwb, tag nrho cov mercury muaj tshwm sim los ntawm 0.4 grams HgSO4 yuav tsum tau dilution nrog 5.4 m 3 dej tshiab kom ua tiav. Qhov noj tau ntawm HgSO4 hauv ib lub county-theem chaw nres tsheb hauv qab Jiangsu tau mus txog 200 grams lossis ntau dua. Dab tsi ntxiv, kev paug qoob loo los ntawm COD tsom tsis yog tsuas yog HgSO4, tab sis nws muaj teeb meem zoo li lwm cov yeeb tshuaj reagents. Silver sulfate, potassium dichromate thiab sulfuric acid tag nrho cov ua rau cov pa phem heev. Tom qab nyeem ntawv nws, nws scares peb. Muaj. Ib qhov project yuav tsim muaj ntau thiab ntau cov kuab paug, uas yuav muaj kev rau txim loj.
Cia wb mus saib cov kev txuas peb yuav tsum xyuam xim rau hauv kev ua haujlwm li cas ntawm ib puag ncig kev sim tshuaj.
1. Tsis muaj cov khoom pov tseg tsis zoo: Yuav tsum muab cov pov tseg tsis txhob pov tseg rau hauv txoj kev hauv tsev. Nws yuav tsum muab cia rau hauv lub chaw kuaj mob nrog cov hnab khib nyiab los sis tej kas tham. Thaum twg tus nqi raug ncav, nws yuav tsum muab pov tseg rau qhov chaw thiab koom siab. Cov dej khoob khoob khoob iav uas tsis zoo yuav tsum tsis raug muab pov tseg thiab yuav tsum muab khaws cia rau hauv ntau lub chaw soj ntsuam kom zoo dua qub.
2. Kev tsim txom khib nyiab: Txhua qhov chaw kuaj yuav tsum npaj ib lub phom los yog lub thawv tshwj xeeb rau kev ceev cov khoom pov tseg, thiab ua tiav ib qho kev kho mob zoo li cas.
3. Cov dej tsis zoo rau organic: Cov tshuaj tsis haum organic, cov tshuaj khib nyiab, thiab lwm yam yuav tsum tsis txhob muab pov rau hauv cov dej phwj tuaj. Lawv yuav tsum tau dej num raws li "hydrocarbons", "halogenated hydrocarbons", thiab lwm yam thiab muab khaws cia rau hauv cov khib nyiab pov tseg tshwj xeeb organic. . Tom qab lub thauv pov tseg tag nrho, nws yuav raug xa mus rau hauv chav pov tseg cia thiab tos rau kev kho mob.
4. Cov dej hauv inorganic kua: Cov dej tsis huv inorganic uas muaj cov hlau tsis tov hauv hlau yuav tsum tsis raug xa tawm ncaj qha los ntawm cov kav dej, tab sis yuav tsum tau muab pov tseg rau hauv cov dej khib nyiab tshwj xeeb. Tom qab lub thauv pov tseg tag nrho, nws yuav raug xa mus rau hauv chav pov tseg cia thiab tos rau kev kho mob. Inorganic khib acid yuav tsum neutralized nrog alkali thiab discharged los ntawm ib cov dej phwj tuaj.
5. Cov nkev nyom: Txhua yam kev sim nrog cov roj siv yuav tsum tau ua nyob rau hauv lub fume hood. Cov kev kuaj mob uas tsim muaj ntau ntau cov roj teeb meem yuav tsum tau txais kev kho mob uas tsim nyog los yog kev tiv thaiv kev tiv thaiv.
Ib puag ncig ntawm ib puag ncig kuaj sim yuav raug cuam tshuam los ntawm huab cua, dej ntws, thiab ib puag ncig. Environmental testing laboratories yog qee zaum zoo li cov chaw muaj kuab paug me me, yog li hom kev kuaj no yuav tsum tau saib xyuas kom muaj kev tiv thaiv ib puag ncig. Nrog rau lub zej zog puas tsuaj, muaj ntau hom ntau hom kev soj ntsuam thiab ntau qhov chaw soj ntsuam ntau dua. Lub teb chaws tau tawm tswv yim txhawb qhov kev tsim kho ntawm kev ua huab cua eco-environmental laboratories. Thaum nws tuaj kuaj kev tsim thiab kev tsim kho, nws yog qhov tsim nyog yuav tau nrhiav cov tuam txhab tsim los tsim, txo cov kev yug me nyuam ntawm cov chaw muaj kuab paug.
