LB-50A型BOD快速測定儀簡介：

是我(wo)公司專為各(ge)(ge)類監測(ce)(ce)和(he)實驗室人員用(yong)于測(ce)(ce)定各(ge)(ge)種(zhong)水(shui)樣生(sheng)化需(xu)氧量(liang)(liang)的儀器，生(sheng)物化學需(xu)氧量(liang)(liang)(Biochemical Oxygen Demand, BOD)作為國際上常用最重要的水質有機污染指標和檢測參數之一。具有測量迅速、準(zhun)確等優點，適用于測定(ding)地表水(shui)(shui)、生活污水(shui)(shui)、工(gong)業廢水(shui)(shui)中的(de) BOD。

執行標(biao)準：

HJ/T 86-2002《水(shui)質 生化需氧量（BOD）的測定 微生(sheng)物傳(chuan)感器快速測定法》

測量原理：                               ;   

LB-50A型BOD快速測定儀采用(yong)微(wei)(wei)(wei)生(sheng)(sheng)(sheng)(sheng)物(wu)(wu)(wu)(wu)(wu)(wu)電(dian)極(ji)法，將微(wei)(wei)(wei)生(sheng)(sheng)(sheng)(sheng)物(wu)(wu)(wu)(wu)(wu)(wu)膜(mo)緊(jin)貼在極(ji)譜式溶(rong)(rong)解(jie)(jie)氧(yang)(yang)(yang)(yang)(yang)電(dian)極(ji)的(de)透(tou)(tou)氧(yang)(yang)(yang)(yang)(yang)膜(mo)表面，即構成微(wei)(wei)(wei)生(sheng)(sheng)(sheng)(sheng)物(wu)(wu)(wu)(wu)(wu)(wu)電(dian)極(ji)。儀(yi)器采用(yong)流(liu)通(tong)(tong)測量方(fang)(fang)式，即樣(yang)品(pin)以流(liu)動方(fang)(fang)式通(tong)(tong)過微(wei)(wei)(wei)生(sheng)(sheng)(sheng)(sheng)物(wu)(wu)(wu)(wu)(wu)(wu)電(dian)極(ji)微(wei)(wei)(wei)生(sheng)(sheng)(sheng)(sheng)物(wu)(wu)(wu)(wu)(wu)(wu)膜(mo)里含(han)有(you)大量好氧(yang)(yang)(yang)(yang)(yang)微(wei)(wei)(wei)生(sheng)(sheng)(sheng)(sheng)物(wu)(wu)(wu)(wu)(wu)(wu)，在有(you)氧(yang)(yang)(yang)(yang)(yang)和有(you)機物(wu)(wu)(wu)(wu)(wu)(wu)的(de)環境(jing)下非(fei)常活躍，氧(yang)(yang)(yang)(yang)(yang)電(dian)極(ji)的(de)輸出(chu)(chu)電(dian)流(liu)與溶(rong)(rong)解(jie)(jie)氧(yang)(yang)(yang)(yang)(yang)的(de)濃(nong)度(du)成正比，不含(han)有(you)機物(wu)(wu)(wu)(wu)(wu)(wu)的(de)液(ye)體通(tong)(tong)過流(liu)通(tong)(tong)池時，透(tou)(tou)過微(wei)(wei)(wei)生(sheng)(sheng)(sheng)(sheng)物(wu)(wu)(wu)(wu)(wu)(wu)膜(mo)的(de)溶(rong)(rong)解(jie)(jie)氧(yang)(yang)(yang)(yang)(yang)幾(ji)乎(hu)沒(mei)有(you)減(jian)(jian)少。當含(han)有(you)有(you)機物(wu)(wu)(wu)(wu)(wu)(wu)的(de)溶(rong)(rong)液(ye)經過流(liu)通(tong)(tong)池時，微(wei)(wei)(wei)生(sheng)(sheng)(sheng)(sheng)物(wu)(wu)(wu)(wu)(wu)(wu)消(xiao)(xiao)耗大量的(de)溶(rong)(rong)解(jie)(jie)氧(yang)(yang)(yang)(yang)(yang)，消(xiao)(xiao)耗的(de)溶(rong)(rong)解(jie)(jie)氧(yang)(yang)(yang)(yang)(yang)與有(you)機物(wu)(wu)(wu)(wu)(wu)(wu)的(de)濃(nong)度(du)成正比，于是導致(zhi)透(tou)(tou)過微(wei)(wei)(wei)生(sheng)(sheng)(sheng)(sheng)物(wu)(wu)(wu)(wu)(wu)(wu)膜(mo)的(de)溶(rong)(rong)解(jie)(jie)氧(yang)(yang)(yang)(yang)(yang)相應減(jian)(jian)少。溶(rong)(rong)解(jie)(jie)氧(yang)(yang)(yang)(yang)(yang)電(dian)極(ji)測出(chu)(chu)溶(rong)(rong)解(jie)(jie)氧(yang)(yang)(yang)(yang)(yang)濃(nong)度(du)的(de)變化量，從而計算出(chu)(chu)BOD 值。
