MS"; font-size: 13px; white-space: normal;"> 化學(xué)需氧量(COD)，是指在強酸并加熱條件下，用重鉻酸鉀作為氧化劑處理水樣時(shí)所消耗氧化劑的量，以氧的mg/L來(lái)表示。對于污水，我國規定用重鉻酸鉀法bai，其測得的值稱(chēng)為化學(xué)需氧量。其方法原理是，在強酸性溶液中，用一定量的重鉻酸鉀氧化水樣中還原性物質(zhì)，過(guò)量的重鉻酸鉀以試亞鐵靈作指示劑，用硫酸亞鐵銨溶液回滴.根據硫酸亞鐵銨的用量du算出水樣中還原性物質(zhì)消耗的氧的量。</p><p

font-family: sans-serif, Arial, Verdana, "Trebuchet MS"; font-size: 13px; white-space: normal;">　　引言：由于化學(xué)需氧量能夠反映了水中受還原性物質(zhì)污染的程度，水中還原性物質(zhì)包括有機物?p亞硝酸鹽p亞鐵鹽p硫化物等.水被有機物污染是很普遍的， COD可以較地表示污水中有機物的含量，測定時(shí)間僅需數小時(shí)，且不受水體限制，所以我們常以COD值作為水樣污染程度的主要參考依據。然而在監測的過(guò)程中，我們常會(huì )遇到許多問(wèn)題，使測量結果偏高或者偏低，以及一些難解現象，接下來(lái)我們進(jìn)行一下分析。</p><p style="color: rgb(51, 51, 51);
