中文摘要：
选用3种不同类型、性能良好的脱墨剂用于混合办公废纸（MOW）中、碱性脱墨，评价不同脱墨工艺的脱墨效果，探讨了添加生物酶、亚硫酸钠等药品对脱墨效果的影响。研究发现，不同类型脱墨剂对中、碱性脱墨的适用性不同，亚硫酸钠与3种不同类型的脱墨剂一起使用对固形物流失率有不同的作用效果，生物酶碱性条件下可以改善脱墨效果，中性条件下效果不显著。
英文摘要：
Three kinds of deinking chemicals were used for neutral deinking or alkaline deinking, the deinking efficiencies were evaluated and the influence of adding enzyme and sodium sulfite on the deinking efficiencies was also investigated. It showed that different kinds of deinking chemicals has different adaptability to neutral deinking or alkaline deinking, and sodium sulfite has different effect on reducing total solid loss when it is used with different kinds of deinking chemicals, enzyme is able to improve the deinking efficiency under alkaline condition, but the efficiency is not notable under neutral condition.
