甲醛在竹浆ECF漂白中的应用探索
The Application of Formaldehyde in ECF Bleaching of Bamboo Pulp
摘要
Abstract
The bamboo pulp after oxygen deligniilcation was bleached using sequences of DOEPD, in this paper. The effect of the factors including kappa factor, initial pH value, bleaching temperature, bleaching time and formaldehyde dosage in Do on the brightness in Do stage were discussed. The results showed that addition of 0.6% formaldehyde in Do stage can increase the pulp final brightness or can save the a-mount of chlorine dioxide at certain target brightness, therefore can reduce AOX load of the effluent and reduce bleaching cost.关键词
