淤泥固化仍存在以下几方面问题
The following problems still exist in sludge solidification
(1)目前淤泥固化大多是在淤泥含水率较高、 呈流动状态下进行的, 这就意味着要加入较多的固化材料,因此不仅固化效果不佳,而且经济适用性差。
(1) At present, sludge solidification is mostly carried out under the condition of high moisture content and flowing state of sludge, which means that more solidification materials should be added. Therefore, not only the solidification effect is poor, but also the economic applicability is poor.
(2)由于河流湖泊水体污染严重, 疏浚淤泥大多含有一定量的污染物, 因此淤泥固化土在道路工程、堤防工程等方面应用时,淤泥固结体中的污染物可能会在雨水的作用下释放出来,对地表水和地下水造成二次污染。
(2) Due to the serious pollution of rivers and lakes, most of the dredged sludge contains a certain amount of pollutants. Therefore, when the sludge solidified soil is applied in road engineering, embankment engineering and other aspects, the pollutants in the sludge consolidated body may be released under the action of rainwater, causing secondary pollution to the surface water and underground water.
(3)关于淤泥固化机理方面的研究主要侧重于定性分析,对于淤泥固化机理的定量研究有待进一步深入。
(3) The research on sludge solidification mechanism mainly focuses on qualitative analysis, and the quantitative research on sludge solidification mechanism needs to be further deepened.
(4)目前对淤泥固化的研究主要以室内试验为主,对于室外试验以及大规模的应用方面研究较少。同时,相对于淤泥固结体的强度指标来说,在耐久性方面比如抗冻性、耐冲刷性等方面的研究较少。
(4) At present, the research on sludge solidification is mainly based on indoor test, and there is less research on outdoor test and large-scale application. At the same time, compared with the strength index of silt consolidated body, there are few studies on durability, such as frost resistance, erosion resistance and so on.
