氯堿工業概況
工(gong)(gong)(gong)(gong)業(ye)(ye)(ye)(ye)上用(yong)電解飽(bao)和NaCl溶液的方法來制(zhi)取NaOH、Cl2和H2，并以(yi)它們為原料生產(chan)一系列化(hua)工(gong)(gong)(gong)(gong)產(chan)品，稱為氯堿工(gong)(gong)(gong)(gong)業(ye)(ye)(ye)(ye)。氯堿工(gong)(gong)(gong)(gong)業(ye)(ye)(ye)(ye)是最基(ji)本的化(hua)學工(gong)(gong)(gong)(gong)業(ye)(ye)(ye)(ye)之一，它的產(chan)品除應(ying)用(yong)于化(hua)學工(gong)(gong)(gong)(gong)業(ye)(ye)(ye)(ye)本身外，還廣泛應(ying)用(yong)于輕工(gong)(gong)(gong)(gong)業(ye)(ye)(ye)(ye)、紡(fang)織工(gong)(gong)(gong)(gong)業(ye)(ye)(ye)(ye)、冶金(jin)工(gong)(gong)(gong)(gong)業(ye)(ye)(ye)(ye)、石(shi)油化(hua)學工(gong)(gong)(gong)(gong)業(ye)(ye)(ye)(ye)以(yi)及(ji)公用(yong)事(shi)業(ye)(ye)(ye)(ye)。
氯(lv)(lv)堿(jian)(jian)(jian)工(gong)(gong)(gong)業(ye)(ye)屬于基本化工(gong)(gong)(gong)原料工(gong)(gong)(gong)業(ye)(ye)，產(chan)(chan)品(pin)涉及國(guo)民經濟和人(ren)民生活的(de)諸多(duo)領域，據測算，每萬噸氯(lv)(lv)堿(jian)(jian)(jian)可(ke)創造5—7億元(yuan)工(gong)(gong)(gong)業(ye)(ye)產(chan)(chan)值。發展(zhan)氯(lv)(lv)堿(jian)(jian)(jian)工(gong)(gong)(gong)業(ye)(ye)，是相關產(chan)(chan)業(ye)(ye)部門的(de)迫切愿望，其發展(zhan)水平，在(zai)一定程(cheng)度上反應(ying)出一個(ge)國(guo)家(jia)國(guo)民經濟的(de)發展(zhan)程(cheng)度。但同時(shi)看到，氯(lv)(lv)堿(jian)(jian)(jian)工(gong)(gong)(gong)業(ye)(ye)又是耗水大戶(hu)、污染大戶(hu)，我國(guo)氯(lv)(lv)堿(jian)(jian)(jian)行業(ye)(ye)亟(ji)待解(jie)決的(de)環境問題之一，是含氯(lv)(lv)產(chan)(chan)品(pin)的(de)持久性有機(ji)污染物控制問題。
