Cov txiaj ntsig thiab cov yam ntxwv ntawm kev tsuag kom qhuav polyaluminum chloride yog dab tsi?

🔬 I. Cov txiaj ntsig ntawm cov khoom siv lub cev thiab tshuaj lom neeg

1. Daim ntawv thiab solubility

• Cov qauv ntawm cov khoom me me uas muaj qhov ntxeem tau: cov khoom tau los ntawm kev tsuag kom qhuav yog nyob rau hauv daim ntawv ntawm cov khoom me me uas muaj qhov ntxeem tau lossis cov khoom me me uas tsis muaj qhov, uas ua rau thaj chaw sib cuag nrog dej ntau ntxiv, thiab qhov ceev ntawm kev ntub dej sai dua li cov khoom hmoov, thiab qhov solubility zoo dua.
• Kev ntws zoo: cov khoom sib xws, kev ua haujlwm tsis muaj plua plav, yooj yim thauj thiab ntxiv.
  2. Kev ruaj khov thiab kev hloov pauv tau
• Kev ruaj khov siab: cov khoom ua haujlwm tau tswj hwm zoo, qhov thermal stability muaj zog, thiab nws tsis yooj yim rau deliquesce thaum lub sijhawm khaws cia.
• Kev hloov kho pH dav dav: siv tau pH 5.0-9.0, tshwj xeeb tshaj yog thaum qhov kub ntawm dej qis, nws tseem tuaj yeem tswj tau flocculation.

⚡ 2. Cov txiaj ntsig ntawm Kev Ua Kom Huv Dej kev ua haujlwm tau zoo

1. Muaj peev xwm ntxuav tau sai

• Tus nqi hydrolysis yog ceev, qhov adsorption caPacQhov dej muaj zog, cov floc loj thiab ntom, qhov nrawm ntawm kev tso dej nce ntxiv 30-50%, thiab qhov turbidity ntawm effluent txo qis heev.
• Nyob rau hauv tib lub dej zoo, qhov ntau tsuas yog 50% ntawm lub nruas ziab PAC, tshwj xeeb tshaj yog rau cov dej muaj kuab paug siab.
  2. Cov nyhuv ua tiav tob
• Nws tuaj yeem tshem tawm SS, COD, BOD thiab cov hlau hnyav (xws li arsenic, lead, mercury) thiab muaj peev xwm tshem tawm xim zoo heev.
• Cov ntsiab lus ntawm cov khoom tsis yaj hauv dej yog tsawg dua 0.3% (phaj thiab thav duab lim tshuab) kom tsis txhob muaj cov yeeb nkab txhaws.

💰 Peb, qhov zoo ntawm kev lag luam thiab kev ua haujlwm

1. Txo cov nqi tag nrho

• Cov tshuaj noj raug txo kom txuag tau tus nqi ntawm cov neeg sawv cev; qhov kev ua haujlwm ntawm lub cev qhuav dej zoo los txo qhov hnyav ntawm kev kho cov sludge.
• Txawm hais tias kev nqis peev rau cov khoom siv siab (kwv yees li 5 lab yuan), tus nqi ua haujlwm mus sij hawm ntev qis dua.
  2. Siv tau yooj yim
• Qib siab ntawm automation, txo cov kev siv zog ntawm tes.
• Nws tuaj yeem ncaj qha ntxiv lossis yaj rau kev siv, tsim nyog rau kev ua haujlwm tas mus li hauv qhov loj Cov nroj tsuag dejs.

🛡 Kev nyab xeeb thiab kev tiv thaiv ib puag ncig

1. Kev ruaj ntseg siab

• Muaj cov ntsev txhuas tsawg dua, thiab cov ntsev hauv dej nce tsawg dua tom qab kho, uas tsis muaj feem cuam tshuam rau kev nyab xeeb ntawm dej haus.
• Kev siv tshuaj ntau dhau yuav tsis ua rau muaj qhov turbidity lossis kev ua qias tuaj ntawm cov dej zoo.
  2. Kev siv rau kev tiv thaiv ib puag ncig
• Siv dav hauv dej haus, dej khib nyiab lag luam (luam ntawv thiab zas xim, electroplating, ua ntawv), dej phwj hauv nroog thiab lwm yam teb, raws li GB15892-2009 tus qauv.

⚖ Kev sib piv thiab kev sau luv luv nrog cov txheej txheem ib txwm muaj

💎 Tshuaj tsuag kom qhuav polyaluminum chloride tau dhau los ua tus neeg sawv cev nyiam hauv kev kho dej vim nws qhov zoo ntawm kev ua haujlwm siab, kev siv tsawg thiab kev tiv thaiv ib puag ncig, thiab kev ua haujlwm yooj yim. Nws yog qhov tshwj xeeb tshaj yog rau cov dej haus thiab cov dej khib nyiab kev lag luam nrog cov kev cai zoo ntawm dej.
