Auto polymer dosing system yog cov cuab yeej tsim nyog rau kev kho cov sludge, cov sludge ntxiv rau tus neeg saib xyuas kom flocculate coagulum thiab tom qab ntawd mus rau hauv cov ntsia hlau ntxaiv rau lub cev qhuav dej, tus neeg sawv cev ntxiv los ntawm lub tshuab ntsia hlau feem ntau yog PAM, tseem hu ua polypropylene acyl roj hmab. , qhov hnyav molecular ntawm 1.5 lab rau 2 lab, qhov concentration yog feem ntau 8%. Cov organic polymer flocculant tuaj yeem tsim cov floc loj dua ntawm cov khoom, uas ua rau muaj qhov cuam tshuam loj heev, thiab condensates cov teeb meem ntab hauv cov dej phwj tuaj rau hauv cov paj sulfone. Qhov piv ntawm kev siv tshuaj feem ntau yog qhov tseem ceeb ntawm lub cev qhuav dej, yog li cov pawg qwj yuav tsum xaiv qhov kev siv tshuaj uas tsim nyog.
PAM dosing khoom yog tsim los ntawm qhuav hmoov dosing ntaus ntawv, peb dissolving tank, agitator, metering twj tso kua mis, kua theem meter, thiab lwm yam Tag nrho cov khoom siv peb theem ntawm kev sib tov, kom PAM muaj peev xwm mus cuag dej thiab yaj. Daim ntawv thov ntawm cov cuab yeej siv tshuaj yog qhov yooj yim, PAM tau ntxiv rau txhiab tus tshuaj txhaj tshuaj, tom qab tswj cov kav raj ntawm cov hmoov qhuav qhuav, cov khoom siv tshuaj, tom qab peb theem ntawm kev sib tov tag nrho, lub twj tso kua mis metering yog precisely. ntxiv rau lub cev dej uas yuav tsum tau dosed.
Thaum cov dej phwj tuaj thiab cov sludge raug kho los ntawm cov ntsia hlau xovxwm dehydrator, qee cov flocculants feem ntau yuav tsum tau ua kom tiav cov txiaj ntsig zoo. Thaum xaiv txoj cai flocculant, peb feem ntau pib los ntawm plaub yam nram qab no.
1. Rau cov sludge nrog cov ntsiab lus siab organic, qhov tseem ceeb tshaj flocculant yog cationic. Qhov siab dua cov ntsiab lus ntawm cov organic, ntau cationic flocculant nrog ntau dua polymerization degree yuav tsum raug xaiv. Rau inorganic sludge, anion tuaj yeem txiav txim siab.
2. Cov khoom sib txawv ntawm cov sludge ncaj qha cuam tshuam rau cov txiaj ntsig zoo, cov khoom siv hluav taws xob thiab cov khoom siv hluav taws xob ntxiv yog qhov nyuaj rau lub cev qhuav dej, thiab cov dej dewatering ntawm cov sludge sib xyaw yog nruab nrab ntawm ob.
3. Feem ntau hais lus, qhov nyuaj rau lub cev qhuav dej ntawm cov sludge, qhov loj dua qhov koob tshuaj flocculation, qhov zoo dua cov sludge hais, uas yuav ua rau kom ntxiv cov flocculant noj, ntau cov organic teeb meem nyob rau hauv cov sludge thiab alkalinity, yuav kuj. ua rau kev nce ntxiv ntawm cov tshuaj flocculant.
4. Tsis tas li ntawd, cov ntsiab lus ntawm sludge tseem cuam tshuam rau kev noj tshuaj flocculant. Feem ntau, qhov siab dua cov ntsiab lus ntawm sludge, qhov ntau npaum li cas ntawm flocculant thaum siv sludge ntsia hlau xovxwm dehydrator.
