Txujci thiab cais ntawm Flocculants

E kab mob

Cov nyhuv ntawm kev ntxiv flocculant feem ntau yog siv los txo lossis tshem tawm qhov kev ua kom tsis haum sedimentation stability thiab polymerization stability ntawm cov khoom tawg nyob hauv dej, ua rau cov khoom tawg tau sib tov sib xyaw, flocculate thiab tshem tawm cov khib nyiab tshem tawm, thiab ntxiv dag zog rau qhov sib cais-kua sib cais.

Thaum qhov luaj li cas ntawm cov xau tshem tawm hauv dej yog qhov txaus me me, lub zog ntawm Brownian cov lus tsa suab txaus los tiv thaiv lub ntiajteb txawj nqus los ntawm kev tawm mus. Ntxiv mus, saum npoo ntawm micro hais feem ntau nqa tib lub nqi tsis zoo, thiab cov lus hais rov qab nruab nrab ntawm tib tus nqi tsis yooj yim rau kev sib koom ua ke thiab loj dua, uas ua rau muaj kev ruaj khov ntawm kev ncua. Qhov flocculant yog cov polymer ua nrog ib qho tshwj xeeb. Cov txheej txheem flocculation yog ntxiv cov nqi zoo los ua cov ntawv "tsis ruaj khov". Los ntawm kev sib tsoo, cov lus hais tau sib nyiam, thiab kev sib xyaw ua ke loj dua, thiaj li ntxiv dag zog rau nag lossis daus nyhuv ntawm qhov me me.

1. Cov khoom siv uas nquag siv tshaj ntawm cov tshuaj polymer polymer yog PAC (polyaluminium chloride) thiab PFS (polyferric sulfate); lawv yooj yim siab rau hauv dej thiab muaj qee yam kev xeb. Nws tuaj yeem muab ntxiv hauv daim ntawv hais daws lossis granule.
2. PAM (polyacrylamide) yog cov khoom siv feem ntau siv cov organic polymer flocculant ; nws yog soluble hauv dej, tab sis tus nqi xaus yog qeeb heev. Feem ntau, nws tau npaj rau hauv kev daws teeb meem ua ntej ntxiv. Nws tuaj yeem faib ua hom anion thiab cation hom. Anionic flocculant feem ntau yog siv rau cov dej phwj tuaj, thiab hom cationic feem ntau yog siv rau sludge dewatering. PAM yog yooj yim rau nqus dej thiab deliquesce rau hauv cov blocks, thiab qhov chaw khaws cia yuav tsum qhuav.
