摘要
对棉浆的高白度漂白进行了研究 ,同时对漂白废水的CODCr进行了测定 ,结果表明用次氯酸盐和二氧化氯对棉浆进行两段漂白可以达到 90 %ISO左右的白度 ,并且漂白废水的CODCr含量很低。
The high brightness bleaching of cotton pulp was studied in this paper , and the COD_(Cr) of the waste water was also mensurate. The results showed that 90%ISO can be got with the HD process, further more, the COD_(Cr) of waste water was very low.
