Cov av khib nyiab yog ib qho ntawm cov pa phem tseem ceeb hauv kev lag luam roj thiab roj.Txhawm rau tiv thaiv kev ua qias tuaj ib puag ncig los ntawm khib nyiab drilling av, nws yuav tsum tau kho.Raws li kev kho mob sib txawv thiab kev tso tawm, muaj ntau txoj hauv kev kho cov av nkos hauv tsev thiab txawv teb chaws.Kev kho mob Solidification yog ib txoj hauv kev siv ntau tshaj plaws, tshwj xeeb tshaj yog tsim rau cov av nkos uas tsis haum rau kev cog qoob loo.
1. Solidification ntawm khib nyiab drilling av nkos
Solidification kev kho mob yog muab ib qho kev faib ua feem ntawm curing tus neeg saib xyuas mus rau hauv lub anti-seepage pov tseg av nkos qhov, sib tov nws tusyees raws li tej yam kev cai, thiab hloov cov teeb meem Cheebtsam mus rau hauv ib tug uas tsis yog-polluting khoom los ntawm lub cev thiab tshuaj hloov rau ib lub sij hawm.
Kev suav cov av nkos solidification: qhov sib npaug ntawm cov theem tom qab cov khoom sib cais ntawm cov cement slurry thiab desander, desilter, khib nyiab pov tseg los ntawm centrifuge, thiab grit tawm ntawm grit tank.
2. MTC technology
Kev hloov cov av nkos rau hauv cov cement slurry, luv luv li MTC (Mud To Cement) thev naus laus zis, yog lub ntiaj teb ua cov tshuab cementing.Slag MTC yog hais txog kev ntxiv dej-quenched blast furnace slag, activator, dispersant thiab lwm yam tshuaj kho rau hauv slurry los hloov cov slurry rau hauv cov cement slurry.Cov tshuab no txo cov nqi kho cov khib nyiab slurry thiab kuj txo cov nqi ntawm cementing.
3. Tshuaj kho kom zoo-kua sib cais
Cov txheej txheem tshuaj kho kom zoo-kua sib cais ua ntej ua cov tshuaj destabilization thiab kev kho flocculation ntawm cov av nkos drilling, ntxiv dag zog rau cov khoom sib cais-kua sib cais, thiab hloov cov khoom tsis zoo hauv cov av nkos rau hauv cov khoom tsis zoo los yog tsis muaj teeb meem lossis txo nws cov leaching tus nqi. Thaum lub sij hawm tshuaj destabilization thiab kev kho flocculation.Tom qab ntawd, cov av tsis ruaj khov thiab flocculated pov tseg yog pumped rau hauv turbo-type drilling kua centrifuge.Lub rotating swirl nyob rau hauv lub drilling kua centrifuge thiab cov agitation generated los ntawm lub rotating nruas sib koom ua ke ua ib tug zoo dynamic nyhuv, uas muaj ib tug muaj zog nyhuv ntawm lub semi-static sedimentation nyob rau hauv lub centrifuge, thiab paub txog cov khoom-kua sib cais, kom cov dej dawb. nruab nrab ntawm cov floc hais thiab ib feem ntawm cov dej intermolecular yog sib cais los ntawm centrifugation.Tom qab kev sib cais ntawm cov kua-kua, tus nqi ntawm cov pa phem (sludge) raug txo, qhov ntim tau txo qis, thiab tus nqi ntawm kev kho mob tsis zoo yog ob npaug.
4. Kev pov tseg cov av nkos los ntawm ntug dej hiav txwv drilling
(1) Kev kho cov av nkos
(2) Kev kho cov roj av nkos
Txheej txheem khiav ntawm av nkos tsis-tav kev kho
(1) Chav tsev khaws khoom.Cov khib nyiab drilling av nkag mus rau hauv cov ntsia hlau conveyor los ntawm cov khoom tswj cov khoom, thiab dej ntxiv rau dilution thiab sib tov.
(2) Khoom-kua sib cais chav tsev.Txhawm rau txo cov ntsiab lus dej thiab cov pa phem ntawm cov av nkos ncuav mog qab zib, nws yog ib qho tsim nyog yuav tsum tau ntxiv cov tshuaj kho mob thiab rov ua dua thiab ntxuav.
(3) Chav tsev kho dej khib nyiab.Cov ntsiab lus ntawm suspended solids nyob rau hauv dej sib cais los ntawm centrifugation yog siab.Cov khib nyiab tshem tawm hauv cov dej raug tshem tawm los ntawm huab cua flotation sedimentation thiab pom qhov system kom txo cov ntsiab lus ntawm cov organic teeb meem hauv cov dej khib nyiab, thiab tom qab ntawd nkag mus rau qhov rov qab osmosis system rau kev kho cov concentration.
