供大家(jia)參考(kao)

首(shou)先選擇的活(huo)性炭應(ying)具有(you)較好(hao)的吸(xi)附(fu)性能，再(zai)生(sheng)后性能恢復較好(hao)，化學穩(wen)定性好(hao)，機械強度高，碘(dian)值、亞(ya)甲藍(lan)值大，價格適中(zhong)，來(lai)源方便，最后要對活(huo)性炭進(jin)行吸(xi)附(fu)容(rong)量測(ce)定、吸(xi)附(fu)等(deng)溫線測(ce)定、柱(zhu)子試驗(yan)以及再(zai)生(sheng)試驗(yan)等(deng)。具體選用注意以下方面(mian):

(1)要了(le)解活(huo)性(xing)炭(tan)的(de)(de)性(xing)能技(ji)術指(zhi)標。因為(wei)活(huo)性(xing)炭(tan)在生產(chan)過程(cheng)中采用工(gong)藝流程(cheng)不一(yi)樣(yang)，活(huo)性(xing)炭(tan)的(de)(de)性(xing)能差別很大，其碘值、亞(ya)甲(jia)藍值、機械強度、比(bi)表面積、總孔容積、中孔容積、堆積密度等都是必須收集(ji)的(de)(de)活(huo)性(xing)炭(tan)性(xing)能技(ji)術指(zhi)標。

(2)注(zhu)意活(huo)(huo)性(xing)(xing)炭(tan)的(de)(de)(de)細孔(kong)(kong)(kong)(kong)(kong)構造情況。活(huo)(huo)性(xing)(xing)炭(tan)在制(zhi)造過程(cheng)中，由(you)于材質(zhi)(zhi)和工藝上的(de)(de)(de)差(cha)異，經(jing)過活(huo)(huo)化(hua)，往(wang)(wang)往(wang)(wang)使活(huo)(huo)性(xing)(xing)炭(tan)內部(bu)所形成的(de)(de)(de)大(da)(da)孔(kong)(kong)(kong)(kong)(kong)、中孔(kong)(kong)(kong)(kong)(kong)、微(wei)孔(kong)(kong)(kong)(kong)(kong)的(de)(de)(de)比(bi)表(biao)(biao)面積(ji)(ji)比(bi)率都(dou)(dou)不(bu)(bu)一樣，造成孔(kong)(kong)(kong)(kong)(kong)容(rong)積(ji)(ji)、比(bi)表(biao)(biao)面積(ji)(ji)也不(bu)(bu)一樣，3種(zhong)孔(kong)(kong)(kong)(kong)(kong)徑(jing)(jing)在水處理(li)中所起的(de)(de)(de)作(zuo)(zuo)用(yong)不(bu)(bu)一樣，大(da)(da)孔(kong)(kong)(kong)(kong)(kong)主要起通(tong)道作(zuo)(zuo)用(yong)，即水中有(you)(you)機(ji)污染物(wu)經(jing)過大(da)(da)孔(kong)(kong)(kong)(kong)(kong)能(neng)(neng)順利而通(tong)暢地(di)進入中孔(kong)(kong)(kong)(kong)(kong)或微(wei)孔(kong)(kong)(kong)(kong)(kong)，中孔(kong)(kong)(kong)(kong)(kong)除(chu)了起通(tong)道作(zuo)(zuo)用(yong)使被吸附(fu)(fu)物(wu)質(zhi)(zhi)到達微(wei)孔(kong)(kong)(kong)(kong)(kong)之外，還能(neng)(neng)對(dui)分(fen)子直徑(jing)(jing)較大(da)(da)的(de)(de)(de)有(you)(you)機(ji)物(wu)質(zhi)(zhi)起到直接吸附(fu)(fu)的(de)(de)(de)作(zuo)(zuo)用(yong)。微(wei)孔(kong)(kong)(kong)(kong)(kong)能(neng)(neng)吸附(fu)(fu)液(ye)相中1nm以下小分(fen)子有(you)(you)機(ji)物(wu)，它的(de)(de)(de)容(rong)積(ji)(ji)和比(bi)表(biao)(biao)面積(ji)(ji)標志著活(huo)(huo)性(xing)(xing)炭(tan)吸附(fu)(fu)能(neng)(neng)力的(de)(de)(de)優(you)劣。對(dui)于水處理(li)用(yong)活(huo)(huo)性(xing)(xing)炭(tan)來說，微(wei)孔(kong)(kong)(kong)(kong)(kong)扣負著除(chu)去水中有(you)(you)機(ji)物(wu)的(de)(de)(de)極其重要的(de)(de)(de)角色。給水用(yong)活(huo)(huo)性(xing)(xing)炭(tan)最(zui)好選擇微(wei)孔(kong)(kong)(kong)(kong)(kong)和過渡孔(kong)(kong)(kong)(kong)(kong)孔(kong)(kong)(kong)(kong)(kong))都(dou)(dou)較為(wei)發達和比(bi)表(biao)(biao)面積(ji)(ji)較大(da)(da)的(de)(de)(de)活(huo)(huo)性(xing)(xing)炭(tan)品種(zhong)。

(3)活(huo)性炭的(de)碘(dian)值(zhi)(zhi)、亞甲(jia)藍(lan)值(zhi)(zhi)。選用活(huo)性炭，一般是依(yi)據(ju)活(huo)性炭的(de)碘(dian)值(zhi)(zhi)和亞甲(jia)藍(lan)值(zhi)(zhi)來進行(xing)選擇的(de)。
