Study on Optimal Concentration and Optimal Proportioning of Flocculants for Taihu Sediment

YU Xin;HU Kun;LI Xia;XU Shen-yang;JIN Zi-ye;School of Science, Tianjin Polytechnic University;School of Textiles, Tianjin Polytechnic University;School of Economics,Tianjin Polytechnic University;  
This paper studied the optimal concentration of different silt flocculants and the optimal proportion of complex flocculants. For the Taihu Lake contaminated sediment, a grouping test method was used to determine the dewatering effect after flocculating the dewatered sludge flocculation group size and the moisture content of the filter cake. Different flocculants were used to make the dehydration effect reach the best concentration; According to different types of flocculants containing different anions and cations, a combination experiment was conducted to obtain the optimal proportion of the double flocculants. The results of this study provide experimental basis for the selection of types and ratios of flocculants for treating lake sediments.
