漂白硫酸盐苇浆制浆废水的处理

Treatment of the Waste Water from a Mill Producing Bleached Kraft Reed Pulp

讨论了漂白硫酸盐苇浆厂制浆黑液和中段废水的实验室处理结果。设计了芦苇BKP制浆废水的处理工艺流程和装置，并重点讨论了各处理段的运行参数和运行结果。BKP苇浆蒸煮黑液首先经厌氧和酸析木素处理，然后再与制浆中段水按工厂排放比例混合，混合废水经活性污泥法处理后，可达到国家标准排放。

Laboratory results of the treatment of pulping black liquor,washing and bleaching waste water of a mill producing bleached kraft reed pulp were presented.Process and installation of reed BKP pulping waste water treatment were designed,operation parameters and running results of treatment stages were discussed.Black liquor after anaerobic treatment and acid precipitating of lignin could be mixed with washing and bleaching waste water based on the discharged ratio of the mill to discharge,the pollution load of the mixed effluent will meet the national regulation requirement after further treatment by active sludge.
