熒光溶解氧計用于監(jiān)測污水處理廠的所有工藝點，包括地表水監(jiān)測，如調(diào)節(jié)池、曝氣池、好氧厭氧消化池和出水監(jiān)測。創(chuàng)新的熒光法取代了傳統(tǒng)的膜傳感器，無需更換隔膜和電解液，減少了維護工作量，提高了工作可靠性。特別適用于污水處理領域惡劣的工作條件。此外，熒光傳感器不消耗氧氣，因此對流速和攪拌沒有要求，并且不會受到硫化物等物質(zhì)的干擾。具有全中文顯示、中文菜單操作、全智能、多功能、測量性能高、環(huán)境適應性強的特點。</span></p><p><span><br/></span></p><p><span>熒光溶解氧計有一層熒光材料。LED光源發(fā)出的藍光照射熒光材料，熒光材料被激發(fā)并發(fā)出紅光；光電管檢測熒光物質(zhì)從發(fā)出紅光返回基態(tài)所需的時間。這個時間只與藍光的發(fā)射時間和氧氣量有關(guān)。探頭有另一個LED光源，在發(fā)出藍光的同時發(fā)出紅光，作為藍光發(fā)射時間的參考。傳感器周圍的氧氣越多，熒光材料發(fā)出紅光的時間越短</span></p><p><span><br/></span></p><p><span>熒光溶解氧計的測量原理：熒光溶解氧計基于熒光猝滅原理。藍光照射熒光材料激發(fā)并發(fā)出紅光，因為氧分子可以帶走能量(淬火效應)。因此，激發(fā)紅光的時間和強度與氧分子的濃度成反比。通過測量激發(fā)紅光和參考光之間的相位差，并將其與內(nèi)部校準值進行比較，可以計算出氧分子的濃度。</span></p><p><span><br/></span></p><p><span>熒光溶解氧計的典型應用：城市污水和工業(yè)廢水處理廠的溶解氧監(jiān)測。溶解氧計主要用于確保水處理過程中有足夠的溶解氧，以維持微生物活性，并通過控制曝氣速率優(yōu)化能源利用。Gli溶解氧計適用于監(jiān)測污水處理廠的所有工藝點。典型的應用環(huán)境包括調(diào)節(jié)池、曝氣池、好氧厭氧消化池和出水監(jiān)測。也可用于地表水、污水、鹵水等水體中溶解氧的測定。</span></p><p><span><br/></span></p><p><span>現(xiàn)場溶氧儀是選擇膜法溶氧，和還是選擇熒光法溶氧，根據(jù)現(xiàn)場實際使用情況，考慮到使用方便和維護簡單，目前推薦的是：熒光法溶氧儀。有具體使用工況，歡迎來電交流。</span></p><p><br/></p>
