1.產品簡介

   根(gen)據濾料(liao)(liao)(liao)介質有(you)所不同(tong)，用(yong)(yong)途(tu)與作用(yong)(yong)也(ye)各有(you)區別，一般有(you)石(shi)英(ying)(ying)砂(sha)、活性碳、錳砂(sha)、無(wu)煙煤等。濾料(liao)(liao)(liao)選用(yong)(yong)石(shi)英(ying)(ying)砂(sha)又叫做石(shi)英(ying)(ying)砂(sha)過濾器(qi)，濾料(liao)(liao)(liao)選用(yong)(yong)無(wu)煙煤稱為(wei)無(wu)煙煤過濾器(qi)，濾料(liao)(liao)(liao)選用(yong)(yong)錳砂(sha)（除鐵(tie)(tie)、錳）稱為(wei)錳砂(sha)過濾器(qi)，濾料(liao)(liao)(liao)選用(yong)(yong)活性炭則成(cheng)為(wei)活性炭過濾器(qi)。也(ye)可(ke)以組合(he)使(shi)用(yong)(yong)。錳砂(sha)過濾器(qi)的(de)(de)主(zhu)要功能是清除懸浮物、機(ji)械雜質、有(you)機(ji)物，降低(di)水的(de)(de)混濁度，吸附、去除水中的(de)(de)色素、余氯(lv)膠(jiao)體及鐵(tie)(tie)離子等，該(gai)機(ji)可(ke)根(gen)據過濾量而選定規格的(de)(de)大小，使(shi)用(yong)(yong)及操作非常簡便。

  鐵(tie)和錳(meng)在(zai)地下（井）水(shui)(shui)中幾乎(hu)同(tong)時存(cun)在(zai)，水(shui)(shui)中含(han)鐵(tie)量(liang)(liang)(liang)較高時，水(shui)(shui)有鐵(tie)腥味，影響水(shui)(shui)的口感，作為造(zao)紙(zhi)、紡織、印染、化工和皮(pi)革精致等生(sheng)產(chan)用(yong)水(shui)(shui)，會(hui)(hui)降低產(chan)品質(zhi)量(liang)(liang)(liang)，含(han)鐵(tie)水(shui)(shui)可使生(sheng)產(chan)用(yong)具發(fa)生(sheng)銹斑(ban)，洗滌(di)衣(yi)物(wu)會(hui)(hui)出(chu)現黃色(se)或棕黃色(se)斑(ban)漬，鐵(tie)質(zhi)沉淀(dian)物(wu)Fe2O3會(hui)(hui)滋長鐵(tie)細菌，阻塞管道，有時會(hui)(hui)出(chu)現紅(hong)水(shui)(shui)。而(er)含(han)錳(meng)量(liang)(liang)(liang)較高的水(shui)(shui)與含(han)鐵(tie)量(liang)(liang)(liang)高的情況相類(lei)似，如使水(shui)(shui)有色(se)、嗅、味，損害紡織、造(zao)紙(zhi)、釀造(zao)、食品等工業產(chan)品的質(zhi)量(liang)(liang)(liang)，家用(yong)器具會(hui)(hui)污染成(cheng)棕色(se)或黑色(se)，洗滌(di)衣(yi)物(wu)會(hui)(hui)有微黑色(se)或淺灰色(se)斑(ban)漬。為此我國《生(sheng)活飲用(yong)水(shui)(shui)衛生(sheng)標準》（GB5749-85）規定(ding)，鐵(tie)含(han)量(liang)(liang)(liang)≤0.3㎎/L，錳(meng)含(han)量(liang)(liang)(liang)≤0.1㎎/L，超過(guo)標準的原水(shui)(shui)須經(jing)除鐵(tie)除錳(meng)處理(li)。長時間(jian)飲用(yong)含(han)鐵(tie)含(han)錳(meng)量(liang)(liang)(liang)過(guo)高的水(shui)(shui)還會(hui)(hui)嚴重影響身體健康，對生(sheng)產(chan)設備腐蝕能力極強。
