摘　　要：麻园河由于长期受到工业、农业以及生活等污染物的排入,河道内的污染物随着泥沙沉积于水体底泥中,导致河道底泥污染严重,不仅影响水体环境,破坏水生态系统功能,同时也降低了河道防洪排涝能力。基于此,根据河道现状,拟定几种不同底泥清淤与处理方案,从施工、成本、效果等方面进行比较分析,最终选取绞吸式挖泥船清淤外加机械脱水固结一体化工艺作为麻园河清淤和底泥处理方案。该方案实施后,麻园河取得良好的治理效果与社会经济效益。Due to the long-term discharge of industrial,agricultural and domestic pollutants into Mayuan River,the pollutants in the river channel are deposited in the bottom mud of the water body along with sediment,resulting in serious pollution of the river channel sediment,which not only affects the water ecological environment,but also reduces the flood control and drainage capacity of the river.Based on the current situation of the river,several different treatment schemes of sediment dredging are proposed and compared in terms of construction,cost and effect.Finally,the integrated process of cutter suction dredger combined with mechanical dewatering and consolidation is selected as the sediment dredging and treatment scheme of Mayuan River.After the implementation of this program,the Mayuan River has achieved good governance effect and social and economic benefits.
