供(gong)大家參(can)考(kao)

首先(xian)選(xuan)擇的活(huo)性(xing)炭應(ying)具有較好(hao)的吸附性(xing)能，再生后性(xing)能恢復較好(hao)，化學(xue)穩定性(xing)好(hao)，機械強度高，碘值、亞甲藍值大，價格適中，來源(yuan)方便，最后要對活(huo)性(xing)炭進(jin)行吸附容量測(ce)(ce)定、吸附等(deng)溫線測(ce)(ce)定、柱子試(shi)驗(yan)以(yi)及(ji)再生試(shi)驗(yan)等(deng)。具體(ti)選(xuan)用(yong)注(zhu)意以(yi)下(xia)方面:

(1)要(yao)了解活(huo)性(xing)炭(tan)(tan)的性(xing)能技術指(zhi)標。因為活(huo)性(xing)炭(tan)(tan)在生產過(guo)程中(zhong)(zhong)采用工藝流(liu)程不一樣，活(huo)性(xing)炭(tan)(tan)的性(xing)能差別很大，其碘值(zhi)、亞甲藍(lan)值(zhi)、機械強度、比(bi)表面積、總(zong)孔容積、中(zhong)(zhong)孔容積、堆積密(mi)度等都是必須(xu)收(shou)集的活(huo)性(xing)炭(tan)(tan)性(xing)能技術指(zhi)標。

(2)注意活(huo)(huo)性炭(tan)(tan)(tan)的(de)(de)(de)細孔(kong)(kong)構造(zao)(zao)情況。活(huo)(huo)性炭(tan)(tan)(tan)在制造(zao)(zao)過(guo)程(cheng)中(zhong)(zhong)(zhong)，由于材質(zhi)(zhi)和(he)(he)(he)工藝上的(de)(de)(de)差異，經過(guo)活(huo)(huo)化(hua)，往(wang)往(wang)使(shi)活(huo)(huo)性炭(tan)(tan)(tan)內部所形成的(de)(de)(de)大孔(kong)(kong)、中(zhong)(zhong)(zhong)孔(kong)(kong)、微(wei)(wei)孔(kong)(kong)的(de)(de)(de)比(bi)(bi)表面(mian)(mian)積比(bi)(bi)率都(dou)(dou)不一樣(yang)(yang)，造(zao)(zao)成孔(kong)(kong)容積、比(bi)(bi)表面(mian)(mian)積也不一樣(yang)(yang)，3種孔(kong)(kong)徑在水(shui)(shui)處理(li)中(zhong)(zhong)(zhong)所起的(de)(de)(de)作(zuo)用(yong)不一樣(yang)(yang)，大孔(kong)(kong)主要(yao)起通道作(zuo)用(yong)，即水(shui)(shui)中(zhong)(zhong)(zhong)有機污染(ran)物(wu)經過(guo)大孔(kong)(kong)能(neng)(neng)順利(li)而通暢地進入(ru)中(zhong)(zhong)(zhong)孔(kong)(kong)或微(wei)(wei)孔(kong)(kong)，中(zhong)(zhong)(zhong)孔(kong)(kong)除(chu)了起通道作(zuo)用(yong)使(shi)被吸附物(wu)質(zhi)(zhi)到達微(wei)(wei)孔(kong)(kong)之外，還能(neng)(neng)對分子(zi)直徑較大的(de)(de)(de)有機物(wu)質(zhi)(zhi)起到直接吸附的(de)(de)(de)作(zuo)用(yong)。微(wei)(wei)孔(kong)(kong)能(neng)(neng)吸附液相中(zhong)(zhong)(zhong)1nm以(yi)下小分子(zi)有機物(wu)，它的(de)(de)(de)容積和(he)(he)(he)比(bi)(bi)表面(mian)(mian)積標志著活(huo)(huo)性炭(tan)(tan)(tan)吸附能(neng)(neng)力(li)的(de)(de)(de)優劣。對于水(shui)(shui)處理(li)用(yong)活(huo)(huo)性炭(tan)(tan)(tan)來(lai)說，微(wei)(wei)孔(kong)(kong)扣負著除(chu)去(qu)水(shui)(shui)中(zhong)(zhong)(zhong)有機物(wu)的(de)(de)(de)極(ji)其重要(yao)的(de)(de)(de)角色。給水(shui)(shui)用(yong)活(huo)(huo)性炭(tan)(tan)(tan)最好選擇(ze)微(wei)(wei)孔(kong)(kong)和(he)(he)(he)過(guo)渡(du)孔(kong)(kong)孔(kong)(kong))都(dou)(dou)較為發(fa)達和(he)(he)(he)比(bi)(bi)表面(mian)(mian)積較大的(de)(de)(de)活(huo)(huo)性炭(tan)(tan)(tan)品種。

(3)活(huo)(huo)性(xing)炭的(de)碘值(zhi)、亞甲藍(lan)值(zhi)。選用活(huo)(huo)性(xing)炭，一般(ban)是依(yi)據活(huo)(huo)性(xing)炭的(de)碘值(zhi)和(he)亞甲藍(lan)值(zhi)來進行選擇的(de)。
