Cov ntsiab lus ntawm kev kho dej khib nyiab rau kev lag luam pov tseg phom sij
Txheej txheem qhia txog kev tswj cov khib nyiab pov tseg
Nrog rau txoj kev loj hlob ntawm kev lag luam, tus naj npawb ntawm cov khib nyiab pov tseg pov tseg los ntawm cov txheej txheem tsim khoom yog nce, xws li cov dej khib nyiab tsim los ntawm kev cob qhia incineration, kev cob qhia kev kho lub cev thiab tshuaj lom neeg, kev cob qhia kev siv dav thiab cov chaw tank.Qhov kev kho cov dej khib nyiab hauv kev lag luam phom sij yog nyuaj vim ntau yam. Cov dej khib nyiab pov tseg tsis zoo no tuaj yeem ua tau raws li cov qauv emission tom qab raug kho los ntawm cov tuam txhab kev tiv thaiv ib puag ncig.
Raws li Txoj Cai Kev Ua Haujlwm Ntawm Cov Khoom Siv Hluav Taws Xob Hluav Taws Xob Hluav Taws Xob Hauv Tsev Thiab Sab Nraud, Cov Txheej Txheem Kev Kho Mob tseem ceeb siv rau cov khib nyiab phom sij yog:
① Kev kho lub cev / tshuaj lom neeg;
② Stabilization/solidification kho;
③ Kev kho mob incineration;
④ Kev kho qhov chaw nyab xeeb.
Qhov zoo ntawm cov dej khib nyiab tsim los ntawm txhua txoj kev sib txawv heev.
Tsis tas li ntawd, ntau yam khoom siv pov tseg uas muaj kev phom sij kho tau ua rau cov dej khib nyiab pov tseg hauv cov chaw pov tseg uas muaj kev phom sij muaj cov yam ntxwv ntawm cov kev hloov pauv loj ntawm cov dej tsis zoo thiab qhov ntau, cov kuab paug tsis zoo thiab nyuaj rau kev kho.
Cov yam ntxwv tseem ceeb thiab teeb meem ntawm lub cev thiab cov dej khib nyiab
► Yam ntxwv ntawm Cov Khoom Siv Hluav Taws Xob Cov Khoom Siv Hluav Taws Xob thiab Cov Khoom Siv Hluav Taws Xob thiab Cov Khoom Siv Hluav Taws Xob
Cov dej khib nyiab, khib nyiab ntsev thiab cov seem uas tsim los ntawm kev lag luam pov tseg uas muaj kev phom sij muaj cov yam ntxwv ntawm ntau qhov chaw, ntau hom, complex muaj pes tsawg leeg, cov ntsiab lus siab ntawm cov tshuaj lom thiab tsis zoo, muaj kev phom sij loj thiab cov nqi kho mob siab, uas nyuaj rau kev kho mob, tshwj xeeb tshaj yog cov tshuaj khib nyiab ntsev. thiab pov tseg residue, uas muaj complex muaj pes tsawg leeg, siab toxicity thiab nyuaj rau kev kho mob.
► Txheej Txheem Txheej Txheem rau Kev Kho Dej Ncua Dej Tsis Zoo:
Kev kho lub cev thiab tshuaj lom neeg yog cov txheej txheem tseem ceeb hauv kev pov tseg cov khoom pov tseg. Nws lub hom phiaj yog txhawm rau txo lossis txawm tias tshem tawm cov teeb meem ntawm cov dej khib nyiab pov tseg tom qab kev kho mob, thiab xa mus rau cov txheej txheem tom ntej rau kev pov tseg zaum kawg. Cov txheej txheem ntawm lub cev thiab tshuaj lom neeg feem ntau yog kho cov khib nyiab pov tseg uas muaj dej ntau, tsis muaj calorific nqi, thiab tsis tuaj yeem muab pov tseg ncaj qha, xws li cov hlau khib nyiab hnyav, cov kua qaub pov tseg, khib nyiab alkali, pov tseg emulsion, thiab cyanide pov tseg kua. Nws cov kua dej tsuas yog los ntawm cov dej khib nyiab tom qab physicochemical tshuaj xws li oxidation, txo, thiab neutralization. Cov kua dej ntawm cov txheej txheem no muaj cov ntsiab lus siab ntawm COD, BOD thiab ntsev, nrog rau qee cov roj pov tseg.
Cov dej khib nyiab pov tseg muaj kev puas tsuaj feem ntau tuaj yeem faib ua plaub pawg: khib nyiab emulsion (emulsion khib nyiab), kua qaub thiab alkali pov tseg, cov dej khib nyiab hnyav hlau (muaj chromium, arsenic, mercury, thiab lwm yam hnyav hlau khib nyiab), thiab cov kua qaub kua qaub. .
Pov tseg emulsion evaporation crystallization txheej txheem kho
Acid thiab alkali pov tseg kua pretreatment + evaporation crystallization txheej txheem
Heavy hlau pov tseg kua kho + evaporation crystallization txheej txheem ntws
Chromium-muaj cov kua ua kua ua ntej ntu + evaporation crystallization
arsenic-muaj pov tseg cov kua pretreatment seem + evaporation crystallization
mercury-muaj pov tseg ua kua seem kho + evaporation crystallization
Lwm yam hnyav hlau khib nyiab + evaporation crystallization
Organic pov tseg kua txheej txheem + evaporation crystallization txheej txheem
ENCO kev lag luam pov tseg kev lag luam physicochemical wastewater kho txheej txheem
Rau cov dej khib nyiab pov tseg saum toj no, pov tseg emulsion (emulsion khib nyiab), kua qaub thiab alkali khib nyiab, dej khib nyiab hnyav hlau (muaj chromium, arsenic, mercury, lwm yam hnyav hlau khib nyiab), high-concentration organic wastewater, kev kho tom ntej tuaj yeem ua ke nrog evaporation crystallization system tsim los ntawm ENCO.
ENCO tsim cov txheej txheem MVR evaporation crystallization los yog cov txheej txheem crystallization ntau raws li cov ntaub ntawv muab los ntawm tus tswv thiab ntau xyoo ntawm kev tsim kho engineering los kho cov dej khib nyiab tom qab kev kho physicochemical. Cov dej uas tsim tau rov qab siv dua hauv cov kab ntau lawm, cov dej concentrated yog merged rau hauv lub evaporation system, thiab crystallization yog outsourced rau kev kho mob.
ENCO pov tseg pov tseg kev lag luam physicochemical wastewater kho txheej txheem xaiv cov hauv paus ntsiab lus:
1.
2, Cov txheej txheem xaiv yuav tsum muaj zog yoog raws, kev ua haujlwm yooj yim thiab kev sib haum xeeb kom hloov mus rau cov kev hloov pauv ntawm cov dej khib nyiab physicochemical zoo;
3, Tsim cov khoom siv hluav taws xob tsis zoo rau cov dej khib nyiab pov tseg uas yooj yim rau kev khiav lag luam, yooj yim rau kev khiav lag luam, muaj cov dej ntws ruaj khov, thiab ua tau raws li cov qauv;
4, Raws li qhov ua tau raws li qhov yuav tsum tau ua ntawm cov txheej txheem dej khib nyiab pov tseg pov tseg, sim txo qhov kev nqis peev, txuag hluav taws xob siv hluav taws xob thiab cov nqi khiav lag luam, thiab txo cov nqi khiav lag luam thiab cov nqi zog.
