摘要:以制浆废液为研究对象，提出了机械蒸汽再压缩（MVR）技术与多效蒸发相结合的组合蒸发工艺，并以化学浆黑液及化机浆废水的蒸发为例，比较了组合蒸发与多效蒸发两种工艺。

Abstract:This paper studies the evaporation technique of pulping waste liquor, and puts forward a new evaporation process which combines mechanical vapour recompression (MVR) and multi-effect evaporation technology. With the evaporation of chemical pulping black liquor & APMP effluent as examples, the two process of combined evaporation and multi-effect evaporation are compared.
