【正文】 外界濕度環(huán)境影響較大。1. 煤氣站含酚廢水的產(chǎn)生 煤氣站工藝流程兩段式煤氣發(fā)生爐的爐出煤氣溫度較高,雜質(zhì)含量較多,需要經(jīng)過凈化、冷卻后,輸送至用氣點燃用,圖1為兩段爐煤氣站環(huán)保節(jié)能型工藝,上段煤氣離開煤氣爐經(jīng)過預(yù)除焦器和靜電除焦器,除去煤氣攜帶的焦油和粉塵,下段煤氣經(jīng)旋風(fēng)除塵器、余熱換熱器和風(fēng)冷器等設(shè)備,除塵、降溫后與上段煤氣混合。就發(fā)生爐煤氣站而言,含酚廢水一直是困擾其發(fā)展的環(huán)保難題,許多專家們經(jīng)過了長期的研究與探討,對蒸汽化學(xué)脫酚法、蒸汽脫酚法、焚燒法、溶劑萃取脫酚法、樹脂脫酚法、磺化煤吸附法、生化法等十幾種酚水治理方法,都曾進行了相當(dāng)時間的應(yīng)用實驗,雖然摸索到了一些行之有效的處理方法,也取得了一定的效果,但是各種方法分別存在諸多嚴重的不足之處,最后不得不棄之不用。 main contaminants。關(guān)鍵詞:兩段爐煤氣站;含酚廢水;主要污染物;蒸發(fā)濃縮法Deal with the phenol water in double stage gas station by evaporation condensing method Yuan Weijun Li Jiansheng (Tangshan Keyuan Environmental Protection Technology & Equipment Co., Ltd. Hebei Tangshan 063020)Abstract: Analysis of the source, quantity of phenol water and the main contaminants in double stage gas station. Expatiate on the evaporation condensing method to deal with the phenol water in double stage gas station. Evaluate on the dealing effects by this method and the corrosion risk. Point out that the evaporation condensing method to deal with and utilize the phenol water in gas station can reach the energysaving and emission reduction effectively which will make a more significant economic and social benefits.Keywords: double st
