COD檢測技術(shù)：

化學(xué)需氧量COD(Chemical 0xygen Demand)是以化學(xué)方法測量水樣中需被氧化的還原性物質(zhì)(通常為有機物)的氧當(dāng)量。這一指標(biāo)在河流污染監(jiān)測、工業(yè)廢水性質(zhì)研究以及廢水處理廠的運行管理中具有重要意義，是快速評估有機物污染程度的關(guān)鍵參數(shù)。COD測量方法有化學(xué)法和物理法，化學(xué)檢測方法包含重鉻酸鹽回流法、分光光度法、快速消解法和快速消解分光光度法;物理檢測方法為紫外吸收法。

紫外吸收法不需要化學(xué)試劑，是基于水中有機物對紫外光及可見光特定波長的選擇性吸收原理，利用水樣對單色光的吸收確定有機物物質(zhì)濃度，建立溶液對特定波長吸光度和COD值之間的關(guān)系。COD值的大小主要取決于其中有機物的組成和濃度，而這些有機物在254nm處都有強烈的吸收。測定污水在波長為254nm處的吸光度，通過建立的吸光度與COD濃度之間的關(guān)系換算出COD濃度值。
