Kev xaiv cov dej khib nyiab kho cov neeg ua haujlwm rau kev ua cov ntxhia
Anionic lossis tsis yog -cov khoom siv ionic polyacrylamide feem ntau yog siv los ua cov dej khib nyiab ntawm cov ntxhia ua cov dej khib nyiab.
Cov khoom lag luam tshwj xeeb thiab ntau npaum li cas yuav tsum tau txiav txim siab los ntawm kev sim, raws li cov txheej txheem kev kho dej xaiv thiab cov yam ntxwv ntawm cov dej ntxhia ntxuav.
Kev siv kom raugpolyacrylamidenyob rau hauv cov ntxhia ua dej khib nyiab tsis tsuas yog txhim kho flocculation thiab zoo kho cov ntxhia ntxuav sludge, tab sis kuj ua lub luag haujlwm tseem ceeb hauv kev tswj cov khoom zoo, txhim kho kev ua haujlwm, thiab txo cov nqi.
Kev ceev faj rau kev siv
1. Kev ua haujlwm zoo ntawm cov khoom hauv dej yog qhov tseem ceeb thaum siv; txwv tsis pub, clumping thiab tsim ntawm "ntses-qhov muag" yuav tshwm sim, ncua sij hawm dissolution.
2. Thaum cov dej sov ua kom nrawm nrawm, qhov kub ntau dhau tuaj yeem ua rau thermal degradation ntawm cov saw hlau polymer, yog li cuam tshuam rau viscosity. Feem ntau, cov dej kub yuav tsum tsis pub tshaj 50 degree.
3. Agitation aids dissolution, tab sis ntau dhau agitation tuaj yeem tawg thiab degrade cov hlua polymer ntev. Marine-style propeller agitator raug pom zoo.
4. Cov tshuaj aqueous yuav tsum tsis txhob khaws cia rau ntau tshaj 48 teev, vim qhov no tuaj yeem ua rau poob qis thiab ua haujlwm tsis zoo.
Cov lus qhia cia
1. Polyacrylamide yuav tsum tau muab cia rau hauv qhov chaw txias, qhuav, thiab zoo - qhov chaw cua.
2. Tsis txhob stack polyacrylamide ncaj qha rau hauv av; Nws yog qhov zoo tshaj plaws khaws cia rau ntawm pallets los tiv thaiv kev nqus dej thiab clumping.
3. Qhov siab stacking yuav tsum txwv; Feem ntau, pawg yuav tsum tsis pub tshaj kaum txheej.
4. Cov polyacrylamide tsis siv yuav tsum tau khaws cia rau hauv lub ntim ntim thiab tsis txhob raug huab cua, vim qhov no ua rau nws yooj yim rau clumping.
5. Ua raws li "thawj-hauv, ua ntej- tawm" txoj cai rau cov khoom muag polyacrylamide.
