font-size:14px">污泥穩定干化定義：污泥穩定干化也稱污泥深度處理。污泥穩定化處理就是降解污泥中的有機物質，進一步減少污泥含水量，殺滅污泥中的細菌、病原體等，打破細胞壁，消除臭味，這是污泥能否資源化有效利用的關鍵步驟。污泥穩定化的方法主要有堆肥化、干燥、堿穩定、厭氧消化等。</span><br /> <span style="font-family:宋體; font-size:14px"> 泥泥處理的“四化”原則：減量化，穩定化，無害化，資源化</span><br /> <span style="font-family:宋體; font-size:14px"> 石灰法污泥穩定處理:</span><br /> <span style="font-family:宋體; font-size:14px"> 石灰與部分游離水發生放熱反應，致使污泥溫度增高，由此導致另一部分游離的水被蒸發，含水率可由80%-85%降低到20%-65%，雖然增加了石灰量，但通過物理化學的雙從作用總體上達到污泥減量化和穩定化的目的。在此過程中如果同時向污泥中投入酸性硫酸鐵鋁粉末，對污泥溫度的迅速提升會起到更積極的效果（視運行情況而定），短時間內溫度可達到100℃左右；</span><br /> <span style="font-family:宋體; font-size:14px"> （1）石灰的投入會使污泥的pH值升高到12左右，通過化學過程會達到良好的除臭效果，如果同時投入酸性硫酸鐵鋁可調制pH值10左右，適合作為肥料改良土壤，達到了資源化的目的；</span><br /> <span style="font-family:宋體; font-size:14px"> （2）pH值和溫度的升高起到了很好的抑制與殺菌作用，保證了利用或處置過程中的衛生安全性，同時達到了穩定化和無害化的目的；</span><br /> <span style="font-family:宋體; font-size:14px"> （3）投加了氧化鈣的堿性污泥，其中部分重金屬離子形成穩定無害的化合物，污泥石灰穩定干化法同時也達到了鈍化重金屬離子的效果；</span><br /> <span style="font-family:宋體; font-size:14px"> （4）改性污泥及顆?；瘡亩纳屏藘Υ婧瓦\輸條件，避免滲濾液對環境的再次污染；</span><br /> <br /> <span style="font-family:宋體;
