供大家參考

首先選(xuan)擇的活性(xing)炭應(ying)具有較好的吸附性(xing)能(neng)，再生后性(xing)能(neng)恢復較好，化學穩定性(xing)好，機械強度(du)高，碘值(zhi)、亞甲藍值(zhi)大，價格(ge)適中，來源方(fang)便，最后要(yao)對活性(xing)炭進行吸附容(rong)量測定、吸附等溫(wen)線測定、柱子試驗以及再生試驗等。具體選(xuan)用注(zhu)意以下方(fang)面:

(1)要了解活(huo)(huo)性(xing)炭的(de)性(xing)能技術指標。因為活(huo)(huo)性(xing)炭在生(sheng)產過程(cheng)中采(cai)用工藝(yi)流程(cheng)不一樣(yang)，活(huo)(huo)性(xing)炭的(de)性(xing)能差別很大，其碘(dian)值、亞(ya)甲(jia)藍值、機械強度、比表面積、總孔(kong)容(rong)積、中孔(kong)容(rong)積、堆積密(mi)度等都是必須收集的(de)活(huo)(huo)性(xing)炭性(xing)能技術指標。

(2)注(zhu)意活性(xing)(xing)(xing)炭(tan)的(de)(de)(de)細孔(kong)(kong)(kong)(kong)構(gou)造情況。活性(xing)(xing)(xing)炭(tan)在(zai)(zai)制造過(guo)(guo)程中(zhong)(zhong)，由于材(cai)質(zhi)(zhi)和工藝上的(de)(de)(de)差異，經(jing)過(guo)(guo)活化，往往使活性(xing)(xing)(xing)炭(tan)內部所形(xing)成的(de)(de)(de)大(da)孔(kong)(kong)(kong)(kong)、中(zhong)(zhong)孔(kong)(kong)(kong)(kong)、微(wei)孔(kong)(kong)(kong)(kong)的(de)(de)(de)比(bi)表(biao)面積(ji)(ji)比(bi)率都(dou)不一(yi)樣，造成孔(kong)(kong)(kong)(kong)容(rong)積(ji)(ji)、比(bi)表(biao)面積(ji)(ji)也不一(yi)樣，3種孔(kong)(kong)(kong)(kong)徑在(zai)(zai)水(shui)(shui)處理(li)中(zhong)(zhong)所起的(de)(de)(de)作用不一(yi)樣，大(da)孔(kong)(kong)(kong)(kong)主(zhu)要(yao)起通(tong)道作用，即水(shui)(shui)中(zhong)(zhong)有(you)(you)機污(wu)染(ran)物經(jing)過(guo)(guo)大(da)孔(kong)(kong)(kong)(kong)能(neng)順(shun)利而通(tong)暢地進入(ru)中(zhong)(zhong)孔(kong)(kong)(kong)(kong)或微(wei)孔(kong)(kong)(kong)(kong)，中(zhong)(zhong)孔(kong)(kong)(kong)(kong)除(chu)了起通(tong)道作用使被吸附物質(zhi)(zhi)到(dao)達微(wei)孔(kong)(kong)(kong)(kong)之外，還能(neng)對分(fen)(fen)子(zi)(zi)直徑較大(da)的(de)(de)(de)有(you)(you)機物質(zhi)(zhi)起到(dao)直接吸附的(de)(de)(de)作用。微(wei)孔(kong)(kong)(kong)(kong)能(neng)吸附液相中(zhong)(zhong)1nm以(yi)下小分(fen)(fen)子(zi)(zi)有(you)(you)機物，它(ta)的(de)(de)(de)容(rong)積(ji)(ji)和比(bi)表(biao)面積(ji)(ji)標志著(zhu)活性(xing)(xing)(xing)炭(tan)吸附能(neng)力的(de)(de)(de)優劣。對于水(shui)(shui)處理(li)用活性(xing)(xing)(xing)炭(tan)來說，微(wei)孔(kong)(kong)(kong)(kong)扣負(fu)著(zhu)除(chu)去水(shui)(shui)中(zhong)(zhong)有(you)(you)機物的(de)(de)(de)極其(qi)重要(yao)的(de)(de)(de)角(jiao)色。給水(shui)(shui)用活性(xing)(xing)(xing)炭(tan)最(zui)好選擇微(wei)孔(kong)(kong)(kong)(kong)和過(guo)(guo)渡孔(kong)(kong)(kong)(kong)孔(kong)(kong)(kong)(kong))都(dou)較為(wei)發達和比(bi)表(biao)面積(ji)(ji)較大(da)的(de)(de)(de)活性(xing)(xing)(xing)炭(tan)品種。

(3)活性(xing)炭的(de)碘值(zhi)、亞甲(jia)藍(lan)值(zhi)。選用活性(xing)炭，一(yi)般(ban)是依(yi)據活性(xing)炭的(de)碘值(zhi)和亞甲(jia)藍(lan)值(zhi)來進(jin)行選擇的(de)。
