Application of Comprehensive Treatment Process in Clear Water Flowing into the Xixi Wetland
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.
