在工業(yè)冷卻水處理、乳制品行業(yè)、肉類加工行業(yè)、其他食品和飲料行業(yè)中都用具有氧化作用的二氧化氯做微生物滅殺劑。在紙漿和造紙行業(yè)用作漂白劑。，在市政污水處理中作消毒劑。工業(yè)污水處理設(shè)施也使用二氧化氯，因?yàn)槎趸葘?duì)某些化合物具有選擇性，包括苯酚、硫化物、氰化物、硫代硫酸鹽、硫醇等。石油和天然氣行業(yè)在向下鉆眼時(shí)使用二氧化氯，并且是一種刺激性添加劑。
在DPD 標(biāo)準(zhǔn)方法中，二氧化氯同DPD（N,N-二乙基-p-苯二胺）反應(yīng)產(chǎn)生一種粉紅色的物質(zhì)。游離的氯（濃度大于6ppm 時(shí)）會(huì)對(duì)這項(xiàng)測(cè)量發(fā)生干擾，在樣品中添加氨基乙酸就可以防止這種干擾。測(cè)量結(jié)果用ppmClO2 來(lái)表示。
