【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.
[Abstract]:In order to quantitatively study the application of the method of dehydration and consolidation integration in dredging of lake bottom silt, combined with the ink lake water restoration project of the lake canal regulation project in Wuhan New area, The composition of mud cake and the water quality of tail water treated by this method were randomly sampled in the project, and the water quality of lake water before and after desilting was monitored for a long time. The purpose of the study could be achieved by analyzing the monitoring data. It is found that the indexes of mud cake and tail water are up to the national standard of comprehensive control of mud water environment in urban lakes, which indicates that the operation and disposal of treated mud cake and the discharge of tail water will not cause damage and pollution to the environment. After comparing and analyzing the water quality before and after desilting, it was found that the concentration of TPN TN and COD in lake water decreased below the engineering design value, which also showed that the treatment process improved the lake water quality on the basis of no re-pollution of the environment.
