Abstract Cyanobacterial blooms could accumulate and form high concentration algal scum in the leeward lakeside, which could seriously damage the aquatic ecology health. Flocculation-sinking is one of the most effective approaches for rapidly mitigating heavy cyanobacterial blooms. But the potential risk of water deterioration would affect the subsequent lake restoration strategies. In this study, three flocculants including polyaluminum chloride (PAC), ferric chloride (FeCl₃) and cationic starch with chitosan (CSC), were used to control heavy cyanobacterial blooms with the chlorophyll-a concentration of 1001.63μg/L. Then, the impacts of flocculation on water quality and submerged macrophyte restoration were evaluated. The result showed that the water turned to black and odorous in FeCl₃ and CSC treatments, with DO dropping to 1.35mg/L and 0.61mg/L, and ammonia nitrogen increasing to 24.93mg/L and 45.74mg/L, respectively. While in PAC treatment, ORP (-76.00mV), DO (3.64mg/L) and ammonia nitrogen (9.25mg/L) were ameliorated, compared with those of -140.43mV, 2.34mg/L, and 13.10mg/L in control treatment, respectively. The duration of severe black-and-odorous water decreased from 15d to 4d, and the restoration potential of submerged macrophyte was promoted. Particularly, the biomass of Elodea canadensis increased significantly, compared with that of the control without cyanobacterial blooms (P<0.05). However, the growth stress of Vallisneria natans and Elodea canadensis in FeCl₃ and CSC treatments was not to be alleviated. CSC treatment could inhibit the growth of leaf, plant height and biomass of Vallisneria natans (P<0.05). Results showed that flocculation and sedimentation could quickly control the heavy cyanobacterial blooms in the lakeside area, but black and odorous water event may occur. Measures, such as aeration for oxygenation, should be implemented to alleviate the deterioration of water quality. Afterwards, appropriate submerged macrophyte should be selected for ecological restoration, for achieving the goal of long-term algal control.
