Koj puas paub? Ntxiv nrog rau cov khib nyiab uas yuav tsum tau muab cais, cov khib nyiab pov tseg kuj yuav tsum tau muab cais.
Raws li cov yam ntxwv ntawm cov khib nyiab pov tseg, nws tuaj yeem muab faib ua yooj yim rau hauv: hloov chaw nres tsheb pov tseg, cov khib nyiab hauv chav ua noj, cov khib nyiab pov tseg, thiab cov nroj tsuag incineration landfill leachate.
Dab tsi yog cov yam ntxwv ntawm plaub hom pov tseg pov tseg?
Cov yam ntxwv ntawm kev hloov chaw nres tsheb leachate:
1. Muaj ntau qhov chaw ntawm cov dej khib nyiab: feem ntau yog cov dej khib nyiab hauv tsev, cov dej khib nyiab pov tseg, thiab cov khib nyiab pov tseg.
2. Vim lub sijhawm nyob hauv lub sijhawm luv luv ntawm cov khib nyiab hauv qhov chaw nres tsheb khib nyiab, qhov tso tawm ntawm cov leachate me me.
3.Qhov concentration ntawm cov pa phem nyob rau hauv qhov chaw nres tsheb hloov yog qis dua li ntawm lwm cov pa phem, thiab cov concentration ntawm COD yog li ntawm 5000 ~ 30000mg / L..
Cov yam ntxwv tseem ceeb ntawm cov dej khib nyiab pov tseg yog:
①Muaj ntau ntau hom organic pollutants, thiab dej zoo yog complex (muaj ntau ntau cov organic tshuaj)
②Kev kub siab ntawm cov pa phem thiab ntau yam kev hloov pauv (thawj BOD thiab COD concentrations yog qhov siab tshaj plaws, mus txog kaum tawm txhiab milligrams ib liter, pH tus nqi ntawm lossis qis dua 7, B / C yog nruab nrab ntawm 0.5-0.6, thiab biochemical zog yog qhov zoo), feem ntau hais lus, COD, BOD, BOD / COD piv txo qis nrog "hnub nyoog" ntawm qhov chaw pov tseg, thiab cov alkalinity nce ntxiv.
③Cov dej zoo thiab cov khoom sib txawv heev: cov dej kom muaj nuj nqis sib txawv heev nrog rau lub caij (lub caij los nag yog pom tseeb ntau dua lub caij qhuav); muaj pes tsawg leeg thiab concentration ntawm cov pa phem kuj hloov nrog lub caij; qhov muaj pes tsawg leeg thiab concentration ntawm cov pa phem hloov nrog lub sijhawm pov tseg.
Cov yam ntxwv tseem ceeb ntawm cov khib nyiab pov tseg hauv cov nroj tsuag incineration yog:
①Cov ntsiab lus siab ntawm COD, BOD, thiab ammonia nitrogen (COD tuaj yeem ncav cuag 40,000 ~ 80,000)
②Lub sij hawm fermentation yog ntev tshaj qhov chaw nres tsheb hloov.
Lub ntsiab nta ntawm chav ua noj khib nyiab leachate:
①High suspended solids: Cov kua dej sib txawv muaj qhov sib txawv ntawm cov khoom raug tshem tawm hauv lub xeev kev sib haum xeeb thiab lub xeev colloidal, siab li 60,000 txog 120,000 mg / L, nrog kev sib cais siab thiab nyuaj rau kev sib cais;
②Cov ntsiab lus roj siab: feem ntau yog tsiaj thiab zaub roj, txog li 3000mg / L tom qab ua ntej kho
③COD siab, feem ntau yooj yim rau biodegrade, mus txog 40,000 txog 150,000 mg / L;
④pH qis (feem ntau yog li 3);⑤siab ntsev.
