【摘要】 为了从定量上研究脱水固结一体化的方法在湖底淤泥疏浚中的应用状况,结合武汉新区湖渠整治项目的墨水湖水体修复工程,在工程中随机抽检该方法处理后的泥饼组成成分和尾水水质,并长期定点监测清淤前后湖水的水质,通过分析监测的数据可以达到研究目的.研究发现,泥饼和尾水的各项指标均达到国家对城市湖泊泥水环境综合治理的相关规定标准,说明处理后的泥饼的运转处置和尾水的排放都不会对环境产生破坏和污染.并且对比分析清淤前后水质后,发现湖水中的TP、TN和COD浓度下降到工程设计值以下,这也说明了在没有再次污染环境的基础上,该项处理工艺改善了湖泊水质.更多还原

【Abstract】 In order to study the dehydration and solidification with consolidation agent on the lake bottom mud dredging in application quantitafively,to random sampling the constituent parts of silt cake and the water quality of filtration after treatment is carried out;and long-term fixed-point monitoring the lake water quality in the water of Moshui Lake restoration project.And the purpose is achieved by analyzing the monitoring data.After the examination,the various indices of silt cake and filtration both are up to the relevant standard for the comprehensive treatment of mud environment of the lake.It is indicated that the disposal of silt cake and the discharge of filtration will not cause damage and pollution to the environment.And there are dramatic decline in the water quality indices such as TP,TN and COD with long-term monitoring of the water quality of the lake.It is indicated that the technology can improve the lake’s water quality.更多还原
