摘　　要：以巢湖湖底有机碎屑为研究对象,基于对有机碎屑中总有机碳的测定,研究了利用好氧强化降解湖底有机碎屑.研究了有机碎屑的可生化性及好氧强化降解湖底有机碎屑的效果,并讨论了有机碎屑的浓度及曝气量对其降解效果的影响.结果说明,处理的有机碎屑具有较好的可生化性,在反应30 h左右,降解达到了平衡,总去除率达到了50.69%,降解速率常数K25为0.19 h-1.有机碎屑的浓度以及曝气量对降解效果具有一定的影响.强化好氧法与传统的对底泥处理的方法相比具有更快、更好的效果,为预防及治理水体黑臭现象提供了新的途径.The organic detritus in sediments of the Lake Chaohu were taken as research subject, based on measured total organic carbon in organic detritus. Research was undertaken on the organic detritus of biodegradability and the results of aerobic enhanced degradation of organic detritus, and the degradation effects of organic detritus on different eoneentratious of organic detritus and aer- ation rates. The results show the organic detritus has high biodegradability. In about 30 h, reaction reached equilibrium concentra- tion, total removal rate was 50.69% , and the degradation rate constant/（25 was 0.19 h^ -1. The concentration of organic detritus and aeration rates have impacts on degradation effect. The method of aerobic enhanced degradation of organic detritus in sediments of the lake is better than traditional method, and provides a new way for the prevention and treatment of black and odorous water.
