With the advancement of water treatment projects in China, sediment treatment faces challenges such as high water content, slow settlement, and demanding dewatering. This study explores the settling effects of different organic synthetic flocculants (APAM, CPAM, NPAM) under varying viscous particles and organic matter content to optimize flocculant selection and improve dewatering efficiency. A volumetric sedimentation experiment evaluated flocculation performance, controlling viscous particles (15%, 35%, 55%) and organic matter (15 g/kg, 40 g/kg, 65 g/kg, 90 g/kg). Results showed that APAM performed best in high viscous particle conditions; CPAM was stable across varying organic matter levels, making it suitable for complex environments; NPAM excelled under high organic matter conditions. The study highlighted interactions between flocculant type, dosage, and silt properties, offering an optimization strategy for sediment treatment. It concludes that APAM suits high viscous particle and low-medium organic matter environments, CPAM is optimal for diverse conditions, and NPAM is effective in high organic matter scenarios. Future work should optimize application strategies, explore new flocculants, and validate their effects in practical applications.
