The occurrence of black bloom is directly related to adequate supply of odor and black substance and redox conditions at the bottom of lakes. Capping with losses and sand was conducted with the sediment from Yueliang Bay, which was heavily polluted and suffered from black blooms in the past years, to investigate the efficiency of black bloom control. The main characteristics of sediment-water system and sensory change process were analyzed. The results shows that capping with losses (0.5cm) and sand (1cm) control the formation of black bloom, from the perspective of visual and olfactory results (semi-quantitative). The main black substance (Fe²⁺) and odor substance (methanethiol and dimethyl trisulfide), in the pore-water of capping sediments was only 1/3 and 1/2 of the control cores, DO concentration and Eh of the bottom water was enhanced up to 100% and to 250 mV, respectively. Eh and pH of the surface capping sediment was also higher than uncapping control cores. Overall, the integrated capping system could eliminate the diffusion of nutrients from sediment and anaerobic microorganisms in the water, block the formation of taste and odors in the water, and prevent the occurrence of black bloom.
