摘　　要：利用印染废水好氧生物处理工艺的剩余污泥,作高浓度印染废水预处理的生物絮凝剂,协同粉煤灰预处理高浓度印染废水,使废水中排放监控指标-色度、悬浮物(SS)和化学需氧量(CODcr)显著降低,为降低后续生化处理负荷、有效降低高浓度印染废水处理的运行成本,探索废物资源化、以废治废产业化的工艺设计方向和途径,提供确切的实验依据。This experiment uses surplus sludge together with the powder ash as the flocculants to pretreat highly concentrated dye-printing wastewater, which leads to the remarkable reduction of the discharge monitoring index in the wastewater - chroma, the suspended solid and the chemical oxygen demand. The finding provides the experimental basis for reducing the consequent biochemical treatment loads, effectively reducing the running cost for highly concentrated dye-printing wastewater disposal, exploring the industrialized technical designing direction and the way on using the waste to deal with the waste.
