過濾/超濾-活性炭吸附組合處理工藝流程在中水處理中也較多采用。這種流程在停留時間、處理效果、占地面積及自動控制操作等方面優于生物處理流程【水處理技術】,但由于單純活(huo)性炭吸(xi)附(fu)飽和周期較(jiao)短,要(yao)經常(chang)再生(sheng)成更(geng)換新炭,使操作管(guan)理復雜,運行成本較(jiao)高(gao)。
生物(wu)活(huo)(huo)性炭(tan)(tan)(tan)(tan)(tan)法(fa)處理污水的(de)(de)(de)過程(cheng),涉及活(huo)(huo)性炭(tan)(tan)(tan)(tan)(tan)顆粒、微(wei)(wei)(wei)生物(wu)、水中(zhong)(zhong)(zhong)污染物(wu)及溶解(jie)氧4個因素的(de)(de)(de)在溶液(ye)中(zhong)(zhong)(zhong)作(zuo)用(yong)(yong)(yong)。活(huo)(huo)性炭(tan)(tan)(tan)(tan)(tan)與污染物(wu)之間的(de)(de)(de)相互作(zuo)用(yong)(yong)(yong)是屬于(yu)(yu)單純(chun)活(huo)(huo)性炭(tan)(tan)(tan)(tan)(tan)吸附(fu)。微(wei)(wei)(wei)生物(wu)與溶解(jie)氧的(de)(de)(de)作(zuo)用(yong)(yong)(yong)是微(wei)(wei)(wei)生物(wu)利用(yong)(yong)(yong)水中(zhong)(zhong)(zhong)的(de)(de)(de)溶解(jie)氧得以繁殖。微(wei)(wei)(wei)生物(wu)降解(jie)水中(zhong)(zhong)(zhong)污染物(wu)的(de)(de)(de)過程(cheng)是微(wei)(wei)(wei)生物(wu)獲取能(neng)量(liang)和(he)(he)營養的(de)(de)(de)過程(cheng)。由(you)于(yu)(yu)活(huo)(huo)性炭(tan)(tan)(tan)(tan)(tan)的(de)(de)(de)吸附(fu)作(zuo)用(yong)(yong)(yong),以及活(huo)(huo)性炭(tan)(tan)(tan)(tan)(tan)和(he)(he)微(wei)(wei)(wei)生物(wu)的(de)(de)(de)協同作(zuo)用(yong)(yong)(yong),可(ke)(ke)以促進生物(wu)炭(tan)(tan)(tan)(tan)(tan)上微(wei)(wei)(wei)生物(wu)對污染物(wu)降解(jie)。因此,生物(wu)活(huo)(huo)性炭(tan)(tan)(tan)(tan)(tan)可(ke)(ke)比單純(chun)活(huo)(huo)性炭(tan)(tan)(tan)(tan)(tan)吸附(fu)容(rong)量(liang),用(yong)(yong)(yong)于(yu)(yu)洗浴污水中(zhong)(zhong)(zhong)處理是經濟有效的(de)(de)(de)。
