摘　　要：针对钱塘江来水含沙量高,水体浑浊、透明度低等特性,以西溪湿地清水入城为例,通过减缓水流流速、投放絮凝剂、底泥疏浚等综合处理工艺,加快悬浮质絮凝沉淀过程、提升来水透明度;并通过耦合来水量、浊度、流速与絮凝剂投放量之间的关系,提出变频投放系统,寻求最经济运行模式。The Qiantang River water is characterized by high sand content,turbidity and low transparency.Taking the clear water into the Xixi Wetland,we adopted methods of slowing flow velocity,adding flocculant and dredging bottom sediment to accelerate the flocculation process and enhance transparency.By coupling relationship between incoming water,turbidity,flow rate and the amount of flocculant,a variable frequency delivery system is established to seek the most economic operation mode.

关 键 词：絮凝剂 原水流速 变频 浊度去除率
