fouling rate 中文意思是什麼

fouling rate 解釋
催化劑中毒率
  • fouling : n. （水管、槍筒等中的）污垢。
  • rate : n 1 比率，率；速度，進度；程度；（鐘的快慢）差率。2 價格；行市，行情；估價，評價；費，費用，運費...
  1. The total surface area as calculated using the fouling resistances in table 1 shall be at least 10 % greater than that calculated using the clean overall transfer rate

    用表1中的污垢熱阻計算出的總表面面積比用? ?總傳熱速率計算出的總表面面積至少大10 % 。
  2. Adding pam was helpless to remove organic matter, but can delay fouling. removal rate of organic matter was better when ph < 7, but fouling would be worse

    在酸性條件下，有機物去除率比中性和堿性條件下高，但膜污染則在酸性條件下最嚴重。
  3. The main conclusion are as bwlow : 1. for microflocilation / uf progress, ferric salts were better than aluminum salts ; the more dose of coagulant, the high removal rate of organic matter. however when dose increased to a certain level ( 6mg / l alo2 ), fouling was higher instead

    主要成果和結論如下: 1 .微絮凝-超濾工藝中，鐵鹽混凝劑比鋁鹽要好;隨著混凝劑投加量的增加，有機物的去除率也隨著增加，但當混凝劑投加量增加到一定量（以al2o3計為6mg / l ）時，反而會加劇膜污染;投加pam （聚丙烯酰胺）對提高有機物去除率沒有幫助，但可以緩解膜污染。
