污水處理廠沉淀后變成沉淀的污泥除臭劑

   沉(chen)(chen)(chen)(chen)淀(dian)(dian)是使廢(fei)水(shui)懸浮物(wu)(wu)質，主(zhu)要是可沉(chen)(chen)(chen)(chen)淀(dian)(dian)固(gu)體，可沉(chen)(chen)(chen)(chen)淀(dian)(dian)固(gu)體在(zai)重力作用(yong)下(xia)下(xia)沉(chen)(chen)(chen)(chen)，從而(er)與廢(fei)水(shui)分離，使水(shui)質變得澄清。方法簡(jian)單易行，分離效果良好，是處理(li)(li)污水(shui)的重要手段。用(yong)于完成沉(chen)(chen)(chen)(chen)淀(dian)(dian)過(guo)程的構筑(zhu)稱為沉(chen)(chen)(chen)(chen)淀(dian)(dian)池。沉(chen)(chen)(chen)(chen)淀(dian)(dian)池可分為預(yu)沉(chen)(chen)(chen)(chen)淀(dian)(dian)、初(chu)沉(chen)(chen)(chen)(chen)淀(dian)(dian)和(he)(he)二次沉(chen)(chen)(chen)(chen)淀(dian)(dian)池。預(yu)沉(chen)(chen)(chen)(chen)淀(dian)(dian)和(he)(he)初(chu)次沉(chen)(chen)(chen)(chen)淀(dian)(dian)在(zai)生(sheng)(sheng)物(wu)(wu)處理(li)(li)構筑(zhu)物(wu)(wu)前，二次沉(chen)(chen)(chen)(chen)淀(dian)(dian)池設在(zai)混凝和(he)(he)生(sheng)(sheng)電鍍廢(fei)水(shui)處理(li)(li)物(wu)(wu)處理(li)(li)構筑(zhu)物(wu)(wu)后，由(you)于它們位置不(bu)同，所起(qi)到的作用(yong)有所不(bu)同。

   污水處理廠或污水處理站的臭味來源于污水中復雜的有機物腐敗，還有污水中含有的硫化物、氧化硫化合物、甲硫醇等惡臭來源。需要處理惡臭，可以用污水沉淀除臭劑處理污水中含有的硫化物、氧化硫化合物、甲硫醇等惡臭。
