目前的COD測量方法根據(jù)工作原理不同，可以分為化學(xué)法、物理法、電化學(xué)法、生物法四種。其中化學(xué)法主要是通過在待測水樣中加入強(qiáng)氧化劑使之與水中還原物質(zhì)發(fā)生反應(yīng)；物理法是基于有機(jī)物對紫外光的吸收作用；電化學(xué)法是通過電解作用生成二價亞鐵離子與Cr6+發(fā)生反應(yīng)，或者通過電生成羥基的自由基來氧化水中的還原性有機(jī)物；生物法主要是利用生物的降解作用來降解水中的有機(jī)物，江蘇智能水質(zhì)分析模塊哪家強(qiáng)。四種方法中較為常用的是化學(xué)法、物理法兩種方法。 </p> <p> <p> 物理法主要是分光光度法，該方法主要基于朗伯比爾定律，通過測定待測水樣在紫外-可見波段對光的吸收程度，然后對比標(biāo)準(zhǔn)COD曲線來進(jìn)行COD的計(jì) 算。物理法主要利用光譜學(xué)原理和實(shí)驗(yàn)分析確定物質(zhì)的組成和結(jié)構(gòu)以及對其化學(xué) 成分進(jìn)行分析，通過建立化學(xué)需氧量與光譜數(shù)據(jù)之間的回歸關(guān)系模型，來預(yù)測有機(jī)污染情況的綜合指標(biāo)[8]。 </p> <p> 與化學(xué)方法相比，紫外-可見光譜法測量時間短，不需要使用化學(xué)試劑，不會產(chǎn)生二次污染；釆用紫外-可見光譜法研制的COD測量儀器，操作簡單，江蘇智能水質(zhì)分析模塊哪家強(qiáng)，對操作人員的要求低，故障率低，體積小等特點(diǎn)，江蘇智能水質(zhì)分析模塊哪家強(qiáng)，可以實(shí)現(xiàn)真正的在線、實(shí)時的水質(zhì)監(jiān)測，擁有非常好的應(yīng)用前景。

對污水來源進(jìn)行分類；Ｄｕｒｒｅｎｔｍａｔｔ等［８］在工業(yè)廢水排放事件的檢測中利用ＵＶ－Ｖｉｓ光譜等指標(biāo)對工業(yè)廢水和市政廢水加以區(qū)分。以上**和學(xué)者將光譜識別技術(shù)應(yīng)用在實(shí)際的水質(zhì)監(jiān)測工作中。這些算法普適性較好，但往往需要多個指標(biāo)來表征水樣類型，才能在識別過程中達(dá)到較高的識別準(zhǔn)確率。所采用的傳感器結(jié)構(gòu)復(fù)雜、算法繁瑣，而小型化便攜式儀器的可用資源一般很有限，上述方法很難實(shí)現(xiàn)。本文提出一種新的可用于ＣＯＤ測量過程的水樣識別算法，在傳統(tǒng)光譜識別技術(shù)的基礎(chǔ)上，根據(jù)ＣＯＤ測量的時域相關(guān)性特點(diǎn)，優(yōu)化光譜識別算法。引入了“歷史結(jié)果隊(duì)列”和“歷史識別因子”的概念，并構(gòu)成級聯(lián)的神經(jīng)網(wǎng)絡(luò)結(jié)構(gòu)。實(shí)驗(yàn)證明，該算法結(jié)構(gòu)能更有效地適應(yīng)ＣＯＤ的實(shí)際測量環(huán)境，有效地提高了光譜識別算法的魯棒性和準(zhǔn)確度，其識別準(zhǔn)確率達(dá)到了９８％以上。與此同時，相比于未使用識別算法的測量結(jié)果，基于該水樣識別算法的光譜ＣＯＤ測量方法具有更好的適應(yīng)性和測量準(zhǔn)確性。</p><p>

吸光度與硝酸根存在較大的相關(guān)性，并提出在250nm左右的光譜位置，吸光度與COD存在很好的相關(guān)性，通過建立該波長處吸光度與COD的回歸模型，實(shí) 現(xiàn)了對于COD值得測定，為后續(xù)的UV-Vis光譜法測量COD奠定了基礎(chǔ)[1GU966 年，H.C.Bramer等人對采用253.7nm光譜位置的吸光度來測量廢水中有機(jī)物濃度進(jìn)行了相關(guān)研究，并且研制成相關(guān)儀器。 </p><div style="width:100%;text-align: center;"><img style="max-width: 640px; max-height: 320px;"

光譜分析法的基本原理，眾所周知，物質(zhì)是由原子構(gòu)成的。原子的主要結(jié)構(gòu)包括位于**的原子核和其外時刻在運(yùn)動著的核外電子兩部分。由能量比較低原理，通常情況下原子處于能量都比較低的穩(wěn)定狀態(tài)，也稱其為基態(tài)。但當(dāng)原子受到外界能量( 如熱能、電能等) 的作用時，原子由于與高速運(yùn)動的氣態(tài)粒子和電子相互碰撞而獲得了能量，使原子中外層的電子從基態(tài)躍遷到更高的能級上，處在這種狀態(tài)的原子稱激發(fā)態(tài)。如果原子中的核外電子由基態(tài)到激發(fā)態(tài)躍遷所需的能量是由光能提供的，且提供的能量數(shù)值上與某一能級能量與比較低能基態(tài)的差相等時，原子就可以恰好將提供能量的光吸收。這樣原來提供能量的光經(jīng) </p> <p> 分光后譜線中便缺少了一些特征光譜線，從而產(chǎn)生原子吸收光譜。吸收光譜原理是對樣品進(jìn)行檢測時先讓其變成蒸汽，明確要對哪種元素進(jìn)行檢測后進(jìn) 行操作，使蒸汽吸收預(yù)檢測元素的特征光譜，通過剩下的強(qiáng)度計(jì)算被吸收的量，從而確定元素含量江蘇智能水質(zhì)分析模塊哪家強(qiáng)</p><p
