工業除臭液在某廠的實際案例

   工(gong)(gong)業廢(fei)(fei)(fei)(fei)(fei)水(shui)(shui)(shui)是指工(gong)(gong)業生(sheng)(sheng)(sheng)產(chan)(chan)過(guo)(guo)(guo)程(cheng)中(zhong)產(chan)(chan)生(sheng)(sheng)(sheng)的(de)廢(fei)(fei)(fei)(fei)(fei)水(shui)(shui)(shui)、污水(shui)(shui)(shui)和廢(fei)(fei)(fei)(fei)(fei)液(ye)，其中(zhong)含(han)有(you)隨(sui)水(shui)(shui)(shui)流(liu)失的(de)工(gong)(gong)業生(sheng)(sheng)(sheng)產(chan)(chan)用(yong)料、中(zhong)間產(chan)(chan)物和產(chan)(chan)品(pin)以及(ji)生(sheng)(sheng)(sheng)產(chan)(chan)過(guo)(guo)(guo)程(cheng)中(zhong)產(chan)(chan)生(sheng)(sheng)(sheng)的(de)污染物。工(gong)(gong)業用(yong)水(shui)(shui)(shui)產(chan)(chan)生(sheng)(sheng)(sheng)的(de)廢(fei)(fei)(fei)(fei)(fei)水(shui)(shui)(shui)如(ru)果隨(sui)意排(pai)放(fang)往往會(hui)對周圍的(de)環境和生(sheng)(sheng)(sheng)態造成(cheng)(cheng)不可逆的(de)傷害(hai)。其中(zhong)化(hua)工(gong)(gong)廢(fei)(fei)(fei)(fei)(fei)水(shui)(shui)(shui)所占比比重大，化(hua)工(gong)(gong)廢(fei)(fei)(fei)(fei)(fei)水(shui)(shui)(shui)就是在化(hua)工(gong)(gong)生(sheng)(sheng)(sheng)產(chan)(chan)中(zhong)排(pai)放(fang)出的(de)工(gong)(gong)藝廢(fei)(fei)(fei)(fei)(fei)水(shui)(shui)(shui)、冷卻水(shui)(shui)(shui)、廢(fei)(fei)(fei)(fei)(fei)氣洗(xi)滌水(shui)(shui)(shui)、設備(bei)及(ji)場地沖洗(xi)水(shui)(shui)(shui)等廢(fei)(fei)(fei)(fei)(fei)水(shui)(shui)(shui)。這些廢(fei)(fei)(fei)(fei)(fei)水(shui)(shui)(shui)如(ru)果不經過(guo)(guo)(guo)處理而排(pai)放(fang)，會(hui)造成(cheng)(cheng)水(shui)(shui)(shui)體的(de)不同(tong)性質和不同(tong)程(cheng)度的(de)污染，影響工(gong)(gong)農(nong)業的(de)生(sheng)(sheng)(sheng)產(chan)(chan)。

（工業(ye)廢水(shui)）

   廣東某油(you)漆生(sheng)產廠一天20油(you)性(xing)涂料廢(fei)(fei)(fei)水(shui)(shui)，油(you)漆蒸(zheng)餾工藝出(chu)(chu)(chu)水(shui)(shui)、廢(fei)(fei)(fei)氣噴(pen)淋塔出(chu)(chu)(chu)水(shui)(shui)、反(fan)應罐清洗廢(fei)(fei)(fei)水(shui)(shui)，廢(fei)(fei)(fei)水(shui)(shui)臭味(wei)非(fei)常重，COD超過(guo)一萬(wan)，廢(fei)(fei)(fei)水(shui)(shui)先破乳后(hou)添加藥劑(ji)(ji)才有反(fan)應。先添加千分之二破乳劑(ji)(ji)絮凝(ning)出(chu)(chu)(chu)水(shui)(shui)把(ba)PH調整至四(si)到(dao)五后(hou)，加入雙氧(yang)(yang)水(shui)(shui)和亞鐵芬頓(dun)，然后(hou)添加氫氧(yang)(yang)化(hua)鈉絮凝(ning)沉淀，出(chu)(chu)(chu)水(shui)(shui)再添加脫色劑(ji)(ji)、PAC、PAM絮凝(ning)沉淀，進一步去(qu)除色度、SS、有機物，出(chu)(chu)(chu)水(shui)(shui)過(guo)膜后(hou)，加親油(you)型乳化(hua)劑(ji)(ji)，乳化(hua)后(hou)回用于(yu)生(sheng)產油(you)性(xing)涂料。

   解決辦法如下：先投加千分之二脫色破乳劑讓其廢水絮凝沉淀，再添加工業除臭液去除有機物，最后添加千分之零點五脫色劑，PAC、PAM絮凝沉淀出清水過超濾。最后展示出澄清透亮的清水。
