Kev lag luam pov tseg yog cov khoom siv pov tseg, cov ntaub ntawv nyoos thiab lwm yam uas tau ua tsis tau zoo. Lub hauv paus ntawm cov khib nyiab nyob ntawm qhov tshwj xeeb ntawm cov kev lag luam (metallurgical, lub teeb, hnyav, tshuaj lom neeg). Lawv tsim nyob rau hauv ntau hom kev lag luam, tab sis yav tom ntej lawv tau muab pov tseg los yog rov siv dua.
Muaj cov khoom pov tseg
Kev lag luam pov tseg yog ntau yam:
- kho vajtse;
- yas;
- tshauv thiab slag;
- tawv;
- roj hmab;
- iav;
- ntoo;
- plaub;
- ntawv thiab duab los qhia;
- Cov Khoom Siv Khoom Siv;
- textile;
- cov khoom noj seem, thiab lwm yam.
Txhua pawg ntawm cov khib nyiab no ua rau muaj kev phom sij ntau rau ib puag ncig, thiab yog hais tias qhov muaj pes tsawg leeg muaj tshuaj lom, muaj mercury thiab lwm yam khoom phem, ces qhov no ua rau muaj kev phom sij rau ib puag ncig.
Cov cai tswj kev lag luam khib nyiab
Cov khib nyiab raug sau ntawm cov lag luam, txheeb raws li kev faib raws li kev txaus ntshai. Muaj cov ntaub ntawv uas tswj kev tswj hwm pov tseg. Tom qab sau khib nyiab, nws yuav tsum raug coj mus pov tseg rau ntawm cov khib nyiab thiab pov tseg. Qhov no tsuas yog ua tau los ntawm cov tuam txhab uas muaj cov ntawv tso cai tshwj xeeb. Lawv yuav tsum ua kom muaj kev nyab xeeb thauj khoom thiab siv cov khoom tshwj xeeb. Cov tshuaj phom sij yuav tsum thauj hauv cov thawv ntim khoom. Txhua yam khoom siv uas rov ua dua tshiab yuav tsum muab xa mus rau qhov chaw tsim khoom rov qab.
Cov yam ntxwv ntawm kev lag luam pov tseg
Txhawm rau txiav txim siab ntxiv hmoo ntawm pov tseg los ntawm cov chaw tsim khoom, nws yog qhov tsim nyog los txiav txim siab cov yam ntxwv ntawm cov ntaub ntawv no:
- dab tsi ceg ceg ntawm kev lag luam tsim;
- ntawm dab tsi theem ntawm kev tsim khoom pov tseg;
- nws cuam tshuam rau tib neeg kev noj qab haus huv;
- dab tsi tsim txom ua rau ib puag ncig;
- tus nqi ntawm cov khib nyiab;
- nws tuaj yeem tsim rov qab;
- yuav siv txoj kev pov tseg twg siv.
Cov ntsiab lus lom hauv cov khoom pov tseg lag luam
Ntau hom kev lag luam pov tseg muaj cov khoom lom uas tsis zoo rau ib puag ncig xwb, tab sis kuj cuam tshuam tsis zoo rau tib neeg kev noj qab haus huv. Siv tsis tau cov khoom siv li no. Lawv yuav tsum tau muab tshuaj ntxuav tawm thiab tom qab pov tseg. Rau qhov no, muaj cov kev faus tshwj xeeb thiab cov av khib nyiab rau qhov muaj kev pheej hmoo siab. Cov paib ua rau muaj kev phom sij muaj xws li cov khoom siv ua haujlwm nrog tshuaj, cov khoom siv roj av, cov khoom siv tshuaj lom neeg, cov tshuaj siv hauv lub chaw soj nstuam thiab tshuaj, khoom siv tso roj. Cov no thiab lwm hom kev pov tseg yuav tsum ua nrog kev saib xyuas zoo.
Cov chav kawm phom sij
Raws li cov neeg kawm ntawv muaj teeb meem ntawm ib puag ncig, muaj tsib chav kawm txog kev nyab xeeb ntawm kev lag luam pov tseg:
- 1 - cov khoom pov tseg ntau tshaj plaws muaj cov mercury thiab galvanic sludge. Cov khoom siv no ua rau muaj kev cuam tshuam tsis zoo rau ib puag ncig thiab tuaj yeem ua rau muaj kev puas tsuaj hauv ib puag ncig.
- 2 - chav kawm phom sij. Cov cawv ntawm cov tshuaj ntawm pawg no yog tshem tawm tsuas yog hauv 30 xyoo. Cov no suav nrog roj teeb, roj, xim tsev, kua roj vanish, cov khoom siv nrog cov hmoov txhuas thiab cov kua qaub.
- 3 - qhov nruab nrab txaus ntshai. Tom qab tus ntawm cov pov tseg no, ib puag ncig tau txum tim rov qab los ntawm 10 xyoo. Cov no yog lubee thiab txhuas khoom.
- 4 - siv cov khoom uas tsis muaj kev phom sij, vim tias cov txiaj ntsig zoo raug tshem tawm hauv 3 xyoos xwb. Feem ntau, cov pab pawg no suav nrog cov khib nyiab hauv kev tsim kho.
- 5 - chav kawm ntawm cov khib nyiab tsis muaj kev phom sij. Cov no yog cov hlau, cov ntawv lag luam, ntoo thiab lwm yam ntaub ntawv. Txhua yam pov tseg no tuaj yeem siv tau thiab tsis ua teeb meem rau ib puag ncig.
Cov txheej txheem rau pov tseg ntawm cov pov tseg industrial
Cov kev cai tau tsim kho rau cov pov tseg ntawm cov pov tseg. Cov khib nyiab raug sau thawj zaug thiab khaws cia rau hauv ib qho chaw raug xaiv. Tom qab ntawd lawv muab faib ua cov uas yuav muab pov tseg thiab cov uas yuav rov ua dua tshiab. Nws yuav tsum raug sau tseg tias zaub mov pov tseg yuav raug xa mus rau tsiaj pub tsiaj. Thaum txhua lub sijhawm ua tiav tag, qhov khib nyiab tshem tawm. Cov khib nyiab uas xa rau pov tseg yuav muab faus hauv qhov av. Feem ntau, cov khib nyiab ua kua tau ntxuav rau hauv cov dej hauv lub cev, tab sis ua ntej ua ntej lawv yuav tsum tau muab tshuaj tua kab mob.
Cov yam ntxwv export
Txhawm rau tshem tawm cov pov tseg kev lag luam, lub tuam txhab yuav tsum muaj daim ntawv tso cai rau cov haujlwm no. Cov khib nyiab yog thauj los ntawm cov tsheb tshwj xeeb. Feem ntau, cov khib nyiab thauj mus rau hauv ib qho twb tau txheeb lawm, uas tau ua tiav ua ntej raws li kev sau npe tshwj xeeb. Txhua yam khoom muaj nws tus kheej qhov xav tau ntawm kev thauj khoom. Piv txwv, pov tseg ntawm chav kawm kev nyab xeeb thib 1 yuav tsum thauj kom zoo zoo hauv cov ntim tshwj xeeb kom tsis txhob ua mob rau ib puag ncig.
Kev saib xyuas pov tseg
Txhawm rau kom txo cov teeb meem kev puas tsuaj ntawm cov khib nyiab ntawm thaj chaw ib puag ncig, muaj cov txheej txheem tswj kev pov tseg. Lub cev tshwj xeeb soj ntsuam kev siv cov kev nyiam huv thiab ib puag ncig. Nws tseem saib xyuas cov txheej txheem ntawm kev tshem cov khib nyiab, los ntawm nws sau mus ua kom tiav kev rhuav tshem. Txhua lub koom haum thauj mus los yuav tshuaj xyuas tas li. Cov no thiab lwm yam kev ntsuas pab tiv thaiv ib puag ncig ntuj los ntawm tus ntawm pov tseg kev lag luam.
