Anthracite lim xov xwm yog cov khoom siv tseem ceeb rau kev kho dej, dav siv hauv cov dej haus, dej khib nyiab, thiab cov txheej txheem dej ntws. Nws cov porosity siab, qhov loj ntawm qhov chaw, thiab cov tshuaj lom neeg ruaj khov ua rau muaj txiaj ntsig zoo ntawm kev tshem tawm cov khib nyiab thiab colloids, tab sis kev ua haujlwm pom tau cuam tshuam los ntawm ntau yam tseem ceeb.
Raw khoom zoo yog lub hauv paus. High - zoo anthracite, nrog cov ntsiab lus carbon ntau dua lossis sib npaug li 80%, muaj cov impurities tsawg dua thiab muaj zog txhua yam muaj zog, zam kev tawg, pulverization, thiab cov pa phem thib ob. Kev hnav tsis taus txaus tiv thaiv kev tawg thaum lub sij hawm pom thiab rov qab ntxuav, txo cov xov xwm poob.
Particle loj gradation thiab uniformity yog qhov tseem ceeb. Oversized hais ua rau impurity nkag mus, thaum undersized sawv daws yuav ua rau clogging thiab siab txaus tsis kam. Kev tsis sib haum xeeb tsis zoo cuam tshuam lub peev xwm lim dej sib sib zog nqus, vim tias cov khoom zoo thiab ntxhib stratify unfavorably tom qab ntxuav.
Lim txaj thickness thiab loading uniformity tseem ceeb heev. Tsis txaus thickness ua rau impurity nkag mus, thaum lub thickness ntau ua rau lub zog noj. Kev thauj khoom tsis sib xws ua rau dej luv luv -circuiting, txo kev pom zoo.
Kev ua haujlwm kom raug thiab kev rov qab ua haujlwm yog qhov tseem ceeb. Kev lim dej ntau dhau ua rau muaj kev cuam tshuam tsis tiav, thaum cov nqi qis dhau los txo kev ua haujlwm. Standard backwashing (12–16 L / (m²·s), 5–8 feeb, 24–72-teev voj voog) rov muaj peev xwm; Kev siv tsis raug lossis lub sijhawm ua rau txhaws lossis tawm xov xwm poob.
Cov dej kub, pH, thiab cov xov xwm sib txuam kuj cuam tshuam kev ua haujlwm. Nruab nrab / tsis muaj zog alkaline tej yam kev mob thiab ruaj khov kub yog qhov zoo. Kev sib txuam nrog quartz xuab zeb thiab magnetite txhim kho kev ua haujlwm tag nrho, thaum tsis zoo sib xws ua rau txheej sib xyaw.
Hauv cov ntsiab lus, xaiv qhov siab - zoo anthracite, optimizing particle loj thiab txaj tsim, standardizing lub lag luam thiab backwashing, thiab xyuas kom meej kev sib raug zoo xov xwm yog qhov tseem ceeb rau maximizing pom efficiency thiab txo nqi khiav hauj lwm.
