<div id="3tzm5vv4jmr" class="NyNewsdetail_tips">更新時間：2022-03-14 點擊次數(shù)：1340</div> <div id="3tzm5vv4jmr" class="NyNewsdetail_con"> <p>溶解氧是指溶解在水里氧的量，通常記作DO，用每升水里氧氣的毫克數(shù)(單位為mg/L或者ppm)表示。有些有機化合物在喜氧菌作用下發(fā)生生物降解，要消耗水里的溶解氧，溶解氧得不到及時補充，水體中的厭氧菌就會很快繁殖，而使水體變黑、發(fā)臭。水中溶解氧的多少是衡量水體自凈能力的一個指標(biāo)。水里的溶解氧被消耗，要恢復(fù)到初始狀態(tài)，所需時間短，說明該水體的自凈能力強，或者說水體污染不嚴(yán)重。否則說明水體污染嚴(yán)重，自凈能力弱，甚至失去自凈能力。</p><p> </p><p>　　那么在線溶解氧分析儀的測量值會受到哪些因素影響呢？</p><p> </p><p>　　1、應(yīng)用場合</p><p> </p><p>　　溶氧電ji可用來測量用來對氧含量會影響反應(yīng)速度、流程效率或環(huán)境的流程進行監(jiān)控：如水產(chǎn)養(yǎng)殖、生物反應(yīng)、環(huán)境測試(湖、溪、海洋)、水/廢水處理、葡萄酒生產(chǎn)。</p><p> </p><p>　　2、溫度補償</p><p> </p><p>　　在線溶解氧分析儀的溫度補償對標(biāo)準(zhǔn)溶氧測量說，溫度影響到氧的溶解度和擴散速度，因此要進行溫度補償。</p><p> </p><p>　　3、環(huán)境影響</p><p> </p><p>　　環(huán)境影響適當(dāng)?shù)娜苎鯇玫乃|(zhì)是好的，所有的生命形態(tài)都需要氧。天然的溪水凈化過程要求有恰當(dāng)?shù)难鹾抗┙o有氧生命形態(tài)。如水中的氧含量低于5.0mg/L，水生物生存就有困難，濃度越低越困難。如氧含量低于1-2mg/L并持續(xù)幾小時將導(dǎo)致水生物大批死亡。</p><p> </p><p>　　4、鹽度修正</p><p> </p><p>　　溶解鹽的存在限制了可溶解于水的氧的含量。氧的濃度和分壓之間的關(guān)系隨著每份樣品溶液鹽度的不同而變化，因此多數(shù)的儀表制造商提供人工調(diào)節(jié)鹽度來修正由離子濃度不同而造成的變化。</p><p style="text-align: center"><img
