Kev phom sij kom tsim nyog los ntawm kev muaj ntau yam kev ua qias tuaj muaj ntau yam kab kuab kuab paug, uas yuav ua rau ib puag ncig kev noj qab haus huv thiab kev noj qab haus huv tib neeg. Thoob ntiaj teb, cov cai tam sim no yuav tsum tau cov tuam txhab kom cais, sau, thiab pov tseg cov khib nyiab pov tseg. Kab lus no yuav tshawb xyuas cov kev faib tawm thiab kev tswj hwm kev phom sij thiab qhia koj sivAeration DiffusersTxhawm rau pov tseg cov tshuaj phom sij hauv dej.
Ntawm kev phom sij txaus ntshai
1. Los ntawm cov tshuaj lom neeg
• Kev pov tseg kev ua kom muaj zog: khib nyiab (ph tsawg dua lossis sib npaug rau 2) thiab khib nyiab Alkalis (p ntau dua lossis sib npaug lossis lwm yam .5), thiab lwm yam.
• Cov tshuaj lom kom pov tseg: suav nrog cov roj ntim muaj cov mercury lossis cadmium thiab cov tshuaj tua kab.
• Flammable \/ reactive pov tseg: feem ntau cov kuab tshuaj thiab roj.
2. Los ntawm lub xeev lub cev
• Kua khib nyiab: cov kuab tshuaj organic, tuaj yeem xa mus rau cov tsheb thauj khoom ua ntej nrogDej phwj.
• Cov khoom khib nyiab: xws li cov hlau hnyav uas muaj lub sludge.
• Qhov ntsuas pa taws: suav nrog volatile organic cov tebchaw (vocs).
3. Los ntawm qhov chaw
• Cov tshuaj lom neeg \/ kws ua tshuaj.
Kev ntsuas kev tswj kom haum
Kev sau kom zoo thiab muaj pov thawj tsim qauv
• Sau ua kua Ntim Ntim:Siv cov hmoov nplej fluoroplastic-lined cov nqus dej nruab nrog cov ntsuas siab kom tau kaw cov li qub nyob rau hauv cov ntaub ntawv.
• Cov Qauv Ntim Khoom:Hnyav hlau-muaj sludge yuav tsum tau ntim rau hauv ob-txheej HDPE los tiv thaiv lub hnab ntim, kub muag ntawm kev qhib, thiab sau npe nrog cov khib nyiab pov tseg.
Cov kauj ruam tseem ceeb hauv PretReatment
• Neutralization ntawm acidic wastewater:Kho PH hauv ob theem-ua ntej nrog limestone kom nqa p rau 4-5 hydroxide rau cov kev kho mob nruab nrab.
• Hnyav Tso Dej:Kho hnyav hlau wastewater los coagulation sedimentation thiab ion sib pauv kom tshem tawm cov kuab lom.
• organic pov tseg:Cov teeb meem organic hauv cov khib nyiab yuav tsum distilled lossis oxidized los decompose cov khoom muaj zog.
Kev ua kom zoo ntawm cov txheej txheem kev kho mob biological
• Dynamen oxygen zaub mov siv dej phwj dej aeration systemer:Rau siab-siab organic whastic wastewater (Cod> 2000 mg \/ l), pib ua pa oxygen ntshiababerationTxhawm rau tuav cov pa oxygen ntawm 6-8 mg \/ u; Hloov mus rau micro-pore aeration thaum lub nra hnyav kom txo tau kev siv hluav taws xob.
Kev cob qhia thiab ua raws li pov tseg
• Thaum muaj kev kub siab rau cov kev kub ntxhov siab, tswj cov cua sov dua li ntawm 1100 degree rau ntau dua li 2 vib nas this kom huv si kom huv si ua kom huv si zoo li cov dioxins. Ua kom cov seem seem dhau los ua kom tclp kev sim ua ntej kev sim ua ntej cov chaw nres nkoj. Cov khib nyiab zoo (xws li cov khib nyiab cov kuab tshuaj) yuav tsum tau ua qhov tseem ceeb siv cov txheej txheem extraction xws li distillation.

Cov ntsiab lus saum toj no tau piav qhia kev tswj hwm cov khib nyiab hauv dej khib nyiab, hais txog qhov tseem ceeb ntawm kev faib tawm, thiab thev naus laus zis hloov zuj zus. Los ntawm kev sib koom tes zoo li cov khoom siv dej pheebsia thiab dej phwj tuaj yeem tsuas yog tswj hwm kev phom sij tab sis kuj yuav txo qis kev siv zog.
