The invention relates to the technical field of river channel cleaning, in particular to a river channel dredging method which comprises the following steps: acquiring various parameters of a river channel and a to-be-dredged part; arranging a plurality of desilting devices at each desilting target position; determining the concentration ratio of aerobic bacteria to anaerobic bacteria in the sludge sample; working parameters of the dredging device are determined according to the water flow speed of the corresponding position and the concentration ratio; the river water suspension turbidity of the desilting target position is obtained, and the sludge deposition speed of the desilting target position is calculated according to the suspension turbidity and the water flow speed; according to the silt deposition speed of each desilting target position, determining an adjustment mode of a desilting device; while the dredging effect is effectively guaranteed, damage to a riverbed in the dredging process is avoided, the riverway is continuously cleaned, and the phenomenon that the riverway is silted again can be avoided.
本发明涉及河道清理技术领域，尤其涉及一种河道清淤方法，包括：获取河道和待清淤部位的各项参数；在各所述清淤目标位置布置若干清淤装置；确定淤泥样品中好氧细菌与厌氧细菌的浓度比；根据对应位置的水流速度及所述浓度比确定清淤装置的工作参数；获取清淤目标位置的河水悬浊度，根据悬浊度与水流速度计算清淤目标位置的淤泥沉积速度；根据各所述清淤目标位置的淤泥沉积速度确定对清淤装置的调整方式；本发明在有效的保证了清淤效果的同时，避免了清淤过程中对河床造成损伤，以及持续对河道进行清理，可以避免河道再次发生积淤现象。
