style="font-size:14px;">造成水中溶氧不足的原因</span></strong> </p> <p> <span style="font-size:14px;">（1）高溫：氧氣在水中的溶解度隨水溫升高而降低，如在一個大氣壓下，水溫由10℃上升到35℃時，空氣中的氧在純水中的溶解度可以由11.27毫克/升降至6.93毫克/升，高溫會引起水體中溶氧降低。此外水產(chǎn)動物和其他生物在高溫時耗氧增多也是一個重要原因。</span> </p> <p> <span style="font-size:14px;">（2）養(yǎng)殖密度過大：水體中眾多生物的呼吸作用增加，生物耗氧量也增大。</span> </p> <p> <span style="font-size:14px;">（3）有機物的分解作用：有機物越多，細菌就越活躍，這種過程通常要消耗大量的氧才能進行，因此容易造成缺氧。</span> </p> <p> <span style="font-size:14px;">（4）無機物的氧化作用：水中存在如硫化氫、亞硝酸鹽等無機物時，會發(fā)生氧化作用消耗大量的溶解氧。</span> </p> <p> <br /> </p><p> <strong><span style="font-size:14px;">溶解氧</span></strong><span style="font-size:14px;">是池塘水體中一個重要的水質(zhì)因子，它不但影響到養(yǎng)殖動物的生長發(fā)育、攝食吸收和生存活動，還影響到水體中有機污染物的分解以及du害物質(zhì)(如：氨氮、亞硝酸鹽和硫化氫等)的降解。靜水池塘的</span><strong><span style="font-size:14px;">溶解氧</span></strong><span style="font-size:14px;">變化主要由浮游植物的光合作用程度和生化耗氧量來決定。由于受到風向、風力以及熱阻力(溫躍層)的影響，而表現(xiàn)為池塘水體溶氧水平和垂直分布的不均勻性。</span> </p> <p> <p> <strong><span

style="font-size:14px;">和原水成分關(guān)系的重點是原水成分中有機物含量和溶解氧的關(guān)系，具體表現(xiàn)在原水中有機物含量越多，微生物為代謝分解這些有機物所需消耗的<strong>溶解氧</strong>就越多，相反就越少了。所以在控制曝氣的時候，要注意水量和廢水中有機物的含量相匹配。</span> </p> <p> <span style="font-size:14px;">當進水量是平時的1.5倍時，若不調(diào)整曝氣量的話，會出現(xiàn)曝氣池出水溶解氧過低，有時甚至會低于0.5mg/L，不利于活性污泥發(fā)揮高效率處理效果。</span> </p> <p> <span

style="font-size:14px;">原水中一些特殊成分的存在，同樣也會影響充氧效果。比如水中洗滌劑的存在、使得曝氣池液面存在隔絕大氣的隔離層，進而影響曝氣效果的提升。</span> 溶解氧指溶解在水中的氧含量。又稱氧飽和值，指水體與大氣中氧交換處于平衡時，水體中溶解氧的濃度?；窗灿砩綄崟r在線檢測水質(zhì)監(jiān)測溶氧儀</p><p
