除雜質刮渣氣浮機 污水溶氣機 污泥濃縮機
有(you)兩種方法(fa)：①使(shi)氣(qi)浮(fu)(fu)(fu)池上的(de)(de)空間呈為真空狀態，處在常壓(ya)(ya)(ya)下的(de)(de)水(shui)流(liu)(liu)進(jin)池后(hou)即(ji)釋出(chu)微氣(qi)泡，稱真空溶(rong)(rong)(rong)氣(qi)法；②空氣(qi)加壓(ya)(ya)(ya)溶(rong)(rong)(rong)入水(shui)中達到(dao)飽和，溶(rong)(rong)(rong)氣(qi)水(shui)流(liu)(liu)減(jian)壓(ya)(ya)(ya)進(jin)入氣(qi)浮(fu)(fu)(fu)池時即(ji)釋出(chu)微氣(qi)泡，稱加壓(ya)(ya)(ya)溶(rong)(rong)(rong)氣(qi)法。后(hou)者較為常用。加壓(ya)(ya)(ya)溶(rong)(rong)(rong)氣(qi)水(shui)可以是所處理水(shui)的(de)(de)全部或(huo)一部分，也可以是氣(qi)浮(fu)(fu)(fu)池出(chu)水(shui)的(de)(de)回流(liu)(liu)水(shui)，回流(liu)(liu)水(shui)量占所處理水(shui)量的(de)(de)百分比稱回流(liu)(liu)比，是影響氣(qi)浮(fu)(fu)(fu)效率(lv)的(de)(de)重要因(yin)素，須由試驗確定。加壓(ya)(ya)(ya)溶(rong)(rong)(rong)氣(qi)法的(de)(de)設備(bei)有加壓(ya)(ya)(ya)泵、溶(rong)(rong)(rong)氣(qi)罐和空氣(qi)壓(ya)(ya)(ya)縮(suo)機等。溶(rong)(rong)(rong)氣(qi)罐為承壓(ya)(ya)(ya)鋼筒，內部常設置導(dao)流(liu)(liu)板或(huo)放置填料。溶(rong)(rong)(rong)氣(qi)罐出(chu)水(shui)通過(guo)減(jian)壓(ya)(ya)(ya)閥或(huo)釋放器進(jin)入氣(qi)浮(fu)(fu)(fu)池。
