Method for controlling combined conditioning and dosing of organic flocculant based on particle size distribution characteristics of dredged sediment

The invention relates to a control method for organic flocculant combined conditioning dosing based on dredged sediment particle size distribution characteristics. And determining the dosage of the double flocculants in the combined conditioning process according to the particle size of the dredged sediment and the dosage of the independently used anionic flocculant. The flocculation time is greatly shortened while the dewatering capacity of the bottom mud is improved, the operation efficiency of actual engineering is improved, and the water content of a mud cake meets the requirement of lt; and the requirement is 30%. According to the method, the defects of huge dosage of a bottom mud medicament, poor dehydration performance, medicament residue or large release amount of nutritive salt in the bottom mud in the prior art are overcome by accurately adding the medicament. 本发明涉及一种基于疏浚底泥粒径分布特性的有机絮凝剂联合调理加药的控制方法。根据疏浚底泥的粒径和单独使用阴离子絮凝剂投加量确定联合调理过程中双絮凝剂的加药量。在提高底泥脱水能力的同时，大幅缩短絮凝时间，提高实际工程的操作效率，泥饼含水率满足
