新型环保清淤技术在江阴城区河道整治中的应用

Application of the new environmental dredging technology on urban river regulation in Jiangyin

江阴市某镇三号河为镇区主要排水通道,两岸临街近路,河道上空桥梁、管线众多,因长年没有整治清淤,导致河道堵塞,水流不畅,水质变差。针对该情况采用"气力泵疏浚+垃圾水下破碎"新技术,对其实施了环保清淤作业处理,达到了预期效果。与常规的挖泥船、泥浆泵等清淤方式相比,该综合技术不仅具有特别适应城区河道情况复杂的特点,还有不会造成水体二次污染、可处理河道淤积层中多种垃圾,以及经济合理、管理方便等优点。

The No.3 River is the main drainage channel of the town in Jiangyin. There are many bridges and pipelines on the two sides of the river. There is poor water flow and water quality in town because of the lack of dredging for many years. A new technology of ＂pneumatic dredging and garbage underwater broken＂ is implemented to achieve the desired results. Compared with the conventional dredger, mud pump and other methods, the integrated technology not only has the characteristics of adapting to urban river, but also has the advantages of keeping away from secondary pollution, that can handle a variety of river sediments, as well as economic rationality, management convenience and so on.
