生物酶脱墨剂在废新闻纸脱墨生产线应用中试

Pilot Test on Application of Enzymatic Deinking Agent in ONP Deinking Line

介绍了生物酶脱墨剂在废新闻纸脱墨生产的应用中试。中试结果表明,用生物酶脱墨剂脱墨生产的纸浆白度、残余油墨量和尘埃度均符合标准;并且,用该脱墨浆生产的新闻纸的各项指标也达到了要求,废水的污染负荷也有所下降。

Pilot test on the application of microbial enzymetic deinking agent in ONP deinking line was carried out. The results showed that the brightness,residual ink and speckiness of the pulp obtained from the deinking line are all up to corresponding quality specifications.Furthermore,every specification of the newspaper produced by the deinked pulp also met the requirement of national standard.The pollution load of waste water was decreased.
