城市内河底泥修复技术的探讨

Technical analysis on remediation of sediment in urban rivers

以福州市鼓台中心区水系综合治理项目为基础,对比分析国内外城市内河治理的方法,探讨各类底泥修复技术措施的优缺点及适用情况。目前,内河底泥修复常用的技术包括底泥疏浚、掩蔽技术、化学修复、生物修复、光催化网技术、矿物质修复技术等。各河道治理应根据不同技术的特点,综合考虑项目的污染程度、周边环境、资金投入、施工期、运营期等因素的影响后,再采取切实可行的技术措施。

Based on the Water System Management of Fuzhou Gutai Central Area,this paper compares and analyses the various methods of urban rivers management at home and abroad,and probes into the advantages and disadvantages of various technical measures for the restoration of sediment.At present,the commonly used techniques include sediment dredging,masking,chemical repair,bioremediation,photocatalytic network and mineral restoration.According to the characteristics of different technologies,the river management should take into consideration the influence of the pollution degree of the project,the surrounding environment,the investment,the construction period,the operation period and so on,and then take practical technical measures.
