| 摘 要： | 爆破浆经二级挤浆提取黑液,黑液经三效真空蒸发浓缩后,送锅炉内燃烧,每立方浓黑液可节煤91.06 kg。提取黑液后造纸综合废水COD质量浓度可控制在1 250～1 450 mg/L,经＂加药沉淀＋水解酸化＋SBR＂工艺处理,可使废水COD排放质量浓度稳定低于100 mg/L。

| Abstract: | Blast pulping waste water is double squeezed to get black liquor.The black liquor then is condensed by triple effect vacuum evaporation.Afterwards it is burned in a boiler.In this way every cubic meter of black liquor saves 91.01 kg coal.The COD of squeezed multiplied waste water is controlled from 1 250 to 1 450 mg/L.Then the water is treated with coagulation flocculation-hydrolytic acidification-SBR process,which makes the COD of the effluent be controlled under 100 mg/L. |
