| description | 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.
