【正文】 為水，從氣化的整體結(jié)果著眼，一般將參與煤的氣化反應(yīng)生成可燃物質(zhì)H2的水蒸氣，與氣化劑中水蒸氣量的比值稱為蒸汽分解率。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 stage gas station。（5）煤氣水封帶入的水 在發(fā)生爐煤氣站中，為比較安全、方便的隔離外界與系統(tǒng)中的煤氣，在部分設(shè)備或煤氣管道處，常設(shè)置若干水封，當(dāng)高溫煤氣掠過(guò)水封液面時(shí)，會(huì)將部分水汽化為蒸汽，混入煤氣中。圖3 含酚廢水蒸發(fā)濃縮法最終治理工藝流程Chart 3 final process flow of evaporation condensing method to deal with phenol water3. 煤氣站含酚廢水治理的相關(guān)問(wèn)題分析 含酚廢水治理效果 煤氣站含酚廢水含酚濃度低，不宜直接回收苯、酚，結(jié)合煤氣發(fā)生爐氣化反應(yīng)特點(diǎn)，利用蒸發(fā)濃縮法
