Txog Cov Tshuaj Tua Kab Tsuag

Koj puas paub? Ntxiv rau cov khib nyiab uas yuav tsum tau cais tawm, cov dej khib nyiab hauv qhov chaw pov tseg kuj yuav tsum tau cais tawm thiab.

Raws li cov yam ntxwv ntawm cov dej khib nyiab pov tseg, nws tuaj yeem muab faib ua: cov dej khib nyiab xa mus rau chaw nres tsheb pov tseg, cov dej khib nyiab hauv chav ua noj, cov dej khib nyiab pov tseg, thiab cov dej khib nyiab pov tseg uas hlawv hauv chaw hlawv.

Cov yam ntxwv ntawm plaub hom dej khib nyiab no yog dab tsi?

Cov yam ntxwv ntawm qhov chaw hloov chaw leachate:

1. Muaj ntau qhov chaw tseem ceeb ntawm cov dej khib nyiab: feem ntau yog cov dej khib nyiab hauv tsev, cov dej khib nyiab ntxuav dej, thiab cov dej khib nyiab pov tseg.

2. Vim yog lub sijhawm luv luv ntawm cov khib nyiab hauv qhov chaw thauj khib nyiab, cov zis ntawm leachate yog me me.

3.Qhov concentration ntawm cov pa phem hauv qhov chaw hloov pauv qis dua li lwm cov pa phem, thiab qhov concentration ntawm COD yog li 5000 ~ 30000mg / L.

Cov yam ntxwv tseem ceeb ntawm cov av nkos leachate yog:

①Muaj ntau hom organic pollutants, thiab cov dej zoo yog qhov nyuaj (muaj ntau ntau yam organic tshuaj)

②Muaj cov pa phem ntau thiab ntau yam kev hloov pauv (thawj qhov BOD thiab COD concentration yog qhov siab tshaj plaws, txog li kaum txhiab milligrams ib liter, pH tus nqi yog ntawm lossis qis dua me ntsis 7, B/C yog ntawm 0.5-0.6, thiab cov khoom biochemical zoo), feem ntau hais lus, COD, BOD, BOD/COD piv txo qis nrog "hnub nyoog" ntawm qhov chaw pov tseg, thiab alkalinity nce ntxiv

③Qhov zoo thiab qhov ntau ntawm cov dej sib txawv heev: qhov ntau ntawm cov dej sib txawv heev nrog rau lub caij (lub caij los nag yog qhov tseeb ntau dua li lub caij qhuav); qhov sib xyaw thiab qhov concentration ntawm cov pa phem kuj hloov pauv nrog rau lub caij; qhov sib xyaw thiab qhov concentration ntawm cov pa phem hloov pauv nrog rau lub sijhawm pov tseg.

Cov yam ntxwv tseem ceeb ntawm cov dej khib nyiab hauv cov chaw hlawv khib nyiab yog:

①Cov COD, BOD, thiab ammonia nitrogen ntau heev (COD tuaj yeem ncav cuag 40,000 ~ 80,000)

②Lub sijhawm fermentation ntev dua li ntawm qhov chaw hloov chaw.

Cov yam ntxwv tseem ceeb ntawm cov khib nyiab hauv chav ua noj:

①Cov khoom khov uas raug tshem tawm ntau: Cov leachates sib txawv muaj cov feem sib txawv ntawm cov khoom khov uas raug tshem tawm hauv lub xeev uas tau daws thiab lub xeev colloidal, siab txog 60,000 txog 120,000 mg / L, nrog rau kev sib kis siab thiab nyuaj rau cais;

②Cov roj ntau: feem ntau yog cov roj tsiaj thiab cov roj zaub, txog li 3000mg / L tom qab kev kho ua ntej

③COD siab, feem ntau yooj yim rau biodegradate, txog li 40,000 txog 150,000 mg / L;

④pH qis (feem ntau yog li 3);⑤cov ntsev ntau.
