Polyaluminum Chloride hauv Aquaculture: Cov txiaj ntsig, Kev noj tshuaj & Cov kev coj ua zoo tshaj plaws (2025 Phau Ntawv Qhia)

Kev lag luam hauv dej muaj cov kev xav tau siab rau qhov zoo ntawm dej, yog li ntau yam organic teeb meem thiab cov pa phem hauv dej aquaculture yuav tsum tau kho kom raws sijhawm. Txoj kev kho mob feem ntau tam sim no yog kev ntxuav dej kom huv los ntawmCov tshuaj flocculant.

Hauv cov dej phwj uas tsim los ntawm kev lag luam aquaculture, muaj ob peb hom pa phem, kev hloov pauv me me hauv cov ntsiab lus, thiab kev siv oxygen tsawg hauv cov txheej txheem biochemical. Yuav kom ua tau raws li qhov yuav tsum tau ua ntawm cov qauv tso pa tawm thiab txhim kho qhov chaw aquaculture. Kev siv polyaluminium chloride tuaj yeem ua tiav cov txiaj ntsig ntawm kev ntxuav dej zoo.

Polyaluminum chlorideua lub luag haujlwm tseem ceeb hauv kev ua liaj ua teb aquaculture thiab muaj ntau yam haujlwm:

1. PAC tuaj yeem ua kom dej zoo sai sai, ua rau cov pa oxygen yaj hauv dej ntau ntxiv, thiab tiv thaiv kev lwj ntawm cov av.

2. Muaj peev xwm tshem tawm qee cov kab mob thiab cov kab mob uas txuas nrog rau cov khoom uas raug dai hauv cov dej

3. Thaum muaj ntau cov organic teeb meem hauv lub cev dej, txoj kev daws cov organic teeb meem hauv lub cev dej yog qhov tseem ceeb heev, thiab kev siv polyaluminum chloride kuj yuav tsum yog ib qho ntawm cov kev xaiv zoo.

4. Kev kho dej ntawm cov ntses uas yug me nyuam: Cov dej zoo ntawm cov kab lis kev cai hauv pas dej muaj ntau cov organic teeb meem xws li cov kab lis kev cai seem thiab cov quav ntses, uas ua rau cov dej pom tseeb thiab eutrophication ntawm cov dej zoo. Kev tso tawm ncaj qha yuav ua rau muaj kuab paug rau ib puag ncig. Qhov no yuav tsum tau lim thiab ntxuav cov dej ntawm cov kab lis kev cai hauv pas dej, thiab tom qab ntawd tso tawm lossis rov ua dua tom qab ua tiav cov qauv tso tawm. Kev siv polyaluminum chloride tuaj yeem ua rau cov khoom me me uas nyuaj rau precipitate mus rau hauv cov khoom loj dua thiab precipitate hauv dej, txo cov COD thiab BOD ntawm lub cev dej thiab txhim kho kev ua haujlwm ntawm kev kho dej ntawm cov ntses uas yug me nyuam.

Polyaluminum chloride yog tsim rau cov dej nyoos ntawm ntau yam turbidities sib txawv kub thiab ntau yam pH.

Yuav tsum nco ntsoov tias polyaluminum chloride yuav tsum tau siv rau hauv qhov ntau thiab tsawg. Kev siv ntau dhau ua rau cov nyhuv flocculation tsis zoo thiab yuav ua rau cov gills ntawm ntses thiab cw txhaws, thiab nws tsis haum rau kev siv mus sij hawm ntev. Tib lub sijhawm, thaum siv nws, nws yuav tsum tau sib koom tes nrog cov dej phwj tuaj yeem tso cov agglomerates ntawm polyaluminum chloride tawm ntawm lub pas dej kom ua tiav kev tshem tawm mus tas li.
