　　附圖說明

cod快速消解儀用于(yu)高(gao)氯(lv)(lv)水(shui)體（水(shui)和廢(fei)水(shui)，氯(lv)(lv)離子濃度(du)大于(yu)1000mg/L，小于(yu)20000mg/L)中的(de)COD樣品除(chu)氯(lv)(lv)、消解。適用行業(ye)：油田、沿海(hai)煉(lian)油廠、油庫、氯(lv)(lv)堿廠、鋼廠、電(dian)廠、農(nong)藥、食(shi)品、紡(fang)織印染企業(ye)、以及廢(fei)水(shui)深海(hai)排放(fang)等高(gao)氯(lv)(lv)廢(fei)水(shui)中的(de)COD測(ce)定。
   對工業廢(fei)水中(zhong)COD的(de)測定(ding)，一般(ban)參照(zhao)國標《水質 化(hua)學需(xu)氧量的(de)測定(ding)  重鉻酸鹽法》 （HJ828-2017），然(ran)而對于含較高濃度(du)氯(lv)化(hua)物的(de)工業廢(fei)水，如采油業、染(ran)料化(hua)工、有機(ji)氯(lv)化(hua)工、鹽湖(hu)鹵水開發(fa)行(xing)業廢(fei)水等(deng)，由于在強酸性條件(jian)下測定(ding)COD時，其(qi)中(zhong)的(de)氯(lv)離子易被重鉻酸鉀(jia)氧化(hua)，因此會影響測定(ding)結果的(de)準(zhun)確性。所以對于高于1000mg/L，小于20000mg/L的(de)高氯(lv)工業廢(fei)水中(zhong)COD的(de)測定(ding)，一般(ban)要求按照(zhao)HJ/T70-2001《高氯(lv)廢(fei)水 化(hua)學需(xu)氧量的(de)測定(ding)  氯(lv)氣校正法》標準(zhun)執行(xing)。
