Cov xuab zeb (thee) ntxuav cov txiv duaj cov khoom organic ntawm sediment (thee) hais, txo lub peev xwm ntawm hluav taws xob, thiab ua rau muaj kev sib sau ua ke thiab nag lossis daus. Lub luag haujlwm tseem ceeb yog cais cov av nkos thiab dej.
Cov khoom yog pob tshab viscous kua, hloov polyaluminum chloride. Nws yog ntxiv rau av nkos thiab dej, ua ke nrog pam, thiab muab tso rau hauv txoj siv, thav duab, lossis centrifuge. Nws tuaj yeem cais cais cov av nkos thiab dej, ua tau zoo siv cov dej muaj txiaj ntsig zoo, thiab ua tiav cov neeg txo qis uas muaj cov neeg ua haujlwm siab.
Cov lus qhia tshwj xeeb:
| Yam | Phiaj qhia ntawv |
| Kev tshwm sim | Tsis muaj kob lossis xim av nplaum ua kua |
| Cov ntsiab lus ruaj ≥% | 19-21 |
| PH | 3.0-7.0 |
Kev siv thiab kev ceev faj:
1) Nws tuaj yeem sib txuam thiab txuas ntxiv txuas ntxiv rau kev kho kom huv si tom qab kev ua kom huv si tom qab ua tiav 5-20 zaug, nplawm, thiab hais daws.
2) Thaum muab cov khoom sib txawv ntawm cov dej thiab dej phwj tuaj, cov tshuaj yuav txiav txim siab raws li cov dej kho, thiab cov tshuaj kho tau los ntawm cov kev sim me me.
Ua tib zoo xaiv ntawm koob tshuaj thiab nplawm yog qhov tsim nyog yuav tsum tau ua kom yooj yim txawm tias kev zam ntawm cov crucing ntawm floc.
