Ntawm cov tshuaj siv nyob rau hauv kev hloov dej thiab aquaculture, feem ntau cov khoom muaj xws li sodium thiosulfate thiab polyaluminium chloride. Sodium thiosulfate thiab polyaluminium chloride yog ob yam khoom siv tshuaj feem ntau siv hauv cov dej ua haujlwm, dej phwj tuaj kho, cov nroj tsuag tshuaj thiab tsev kho mob, thiab tuaj yeem yuav hauv khw muag tshuaj reagent. Lawv yog cov pheej yig, muaj txiaj ntsig zoo thiab muaj kev phiv me ntsis. Yog li ntawd, lawv yuav tsum tau siv los ua lub hom phiaj ntawm kev txhim kho dej thiab hloov dej rau cov tsev neeg aquaculture zoo tib yam. Niaj hnub no, feem ntau ntawm cov dej tswj thiab priming tshuaj nyob rau hauv lub lag luam muaj sodium thiosulfate los yog polyaluminium chloride, uas yog ib tug zoo tshuaj rau regulating dej zoo, detoxifying thiab tua xiav (ntsuab) algae.
PAC lub luag haujlwm dab tsi hauv aquaculture?
- Kev kho ntawm aquaculture tail dej.
Qhov zoo ntawm lub pas dej aquaculture dej muaj ntau cov organic xws li kev yug me nyuam cov khoom seem thiab cov ntses excrement, uas ua rau txo qis ntawm cov dej ntshiab, eutrophication ntawm cov dej zoo, thiab kev tso tawm ncaj qha ntawm cov dej yuav ua rau ib puag ncig muaj kuab paug. Yog li ntawd, nws yog ib qho tsim nyog los lim thiab ntxuav cov dej hauv dej hauv lub pas dej, thiab tom qab ntawd tso tawm lossis rov ua dua tom qab ua tiav cov txheej txheem tawm. Kev siv cov polyaluminium chloride tuaj yeem ua rau colloidal hais uas nyuaj rau hauv dej sai sai, coagulate, agglomerate thiab flocculate rau hauv cov khoom loj dua los nag, txo qis COD thiab BOD ntawm cov dej hauv lub cev, thiab txhim kho kev ua haujlwm ntawm tus Tsov tus tw dej.
- Kev kho dej zoo hauv huab cua tshwj xeeb.
Lub caij ntuj sov kub thiab los nag, yooj yim ua rau muaj kev puas tsuaj los ntawm dej nyab, ntau cov av nkos, ntau hom khib nyiab yooj yim ntws mus rau hauv lub pas dej aquaculture, ua rau turbidity ntawm lub cev dej, yog li stimulating cultured ntses, ua rau muaj kev nyuaj siab tuag. Nyob rau lub sijhawm no, ntxiv polyaluminium chloride tuaj yeem daws cov av noo thiab cov organic teeb meem hauv lub cev, tsis txhob turbidity ntawm cov dej hauv pas dej, sai sai rov qab pob tshab ntawm lub pas dej thiab txhim kho oxygen tsim peev xwm ntawm phytoplankton. Nyob rau tib lub sijhawm, tom qab kev puas tsuaj dej nyab, lub cev dej pH yog ib qho yooj yim los ua cov kua qaub ntau dhau, thiab polyaluminium chloride pH yog alkaline, uas tuaj yeem ua lub luag haujlwm hauv kev ruaj khov ntawm lub cev pH.
- Deodorization thiab sterilization
Polyaluminium chloride muaj lub luag haujlwm ntawm deodorizing, tshuaj tua kab mob thiab tshuaj tua kab mob hauv aquaculture. Nws tuaj yeem decompose oxides los tsim cov organic teeb meem, organic sulfide, organic nitrogen, thiab lwm yam., nqus thiab decompose cov tshuaj lom xws li ammonia nitrogen thiab nitrite, thiab tua cov kab mob sai sai thiab tiv thaiv kev loj hlob ntawm cov kab mob tsis zoo.
Tsis Siv Neeg Ntev!
Polyaluminium chloride, sodium thiosulfate thiab lwm yam flocculants yog cov dej ntshiab flocculants, uas tsuas yog siv los daws cov teeb meem dej tsis zoo ib ntus thiab tsis tuaj yeem siv los ua cov khoom hloov dej mus ntev.
