KP木浆厂污冷凝水的汽提处理

硫酸盐浆厂ＣＯＤ和ＢＯＤ物质的排放是很大的污染源，蒸煮冷凝水和蒸发冷凝水是浆厂排放ＣＯＤ和ＢＯＤ物质的主要组成，本文详细介绍了污冷凝水的处理与回用技术，提出污冷凝水全封闭循环用于工艺生产系统，可使硫酸盐浆厂污染物质的排放减到最少，从而获得最佳的经济效益和环境效益。

Steam Stripping of the Contaminated Condensate of a KP Mill

Contaminated condensate of pulping and evaporating plants is the main source of COD and BOD of the effluent of the KP mill, the capital and operation costs of effluent treatment of the mill can be reduced significantly when the secondary condensate is seperated from the contaminated condensate and treated with different ways such as steam stripping. And the COD and BOD discharges of the mill can also be minimized by using a closed contaminated condensate circulation syatem, therefore a best economy and environmental benefit can be obtained.
