摘　　要：净水厂生产废水直接回用到水厂前端,将使原水浊度升高,在一定范围内可增加絮凝核心,提高颗粒的碰撞概率强化低温低浊水的混凝效果。以哈尔滨磨盘山水厂生产废水为对象,研究了生产废水的沉降性能和活性性能。研究表明,生产废水含有氢氧化物的活性成分,回用后能够强化混凝效果,而且含固率、回用混合水浊度及生产废水浊度具有较好的线性相关。The reuse of production wastewater in the front part of water treatment plant will increase the turbidity of raw water and increase the flocculation core in some range, which will increase the collision probability of particles and enhance the coagulation effects in cold and low turbidity water. By studying the Harbin Mopanshan Water Treatment Plant production wastewater, the sedimentation and activity characteristics of production wastewater were studied. The results showed that the production wastewater contained the active ingredient of hydroxide, which could improve the coagulation effects and the solid content ratio, turbidity and reuse of wastewater mixed water turbidity had a good linear correlation with each other.
