河道污泥成分复杂，含有大量微生物、病原体、重金属及有机污染物等。随着全球经济的发展和改造地球地理环境活动的增加，沿海和内陆河流及湖泊的清淤作业工作越来越多。由于这些污泥或淤泥颗粒小、不易脱水、承载力低、有机物含量高、流动性大等缘故，无法直接用作填海工程、堤防工程、道路工程中的工程填土。
The composition of river sludge is complex, containing a large number of microorganisms, pathogens, heavy metals and organic pollutants. With the development of global economy and the increase of activities to transform the earth's geographical environment, there are more and more desilting operations on coastal and inland rivers and lakes. Because these sludge or sludge particles are small, not easy to dehydrate, low bearing capacity, high organic content and high fluidity, they can not be directly used as engineering fill in reclamation engineering, embankment engineering and road engineering.
将污泥通过固化处理技术进行资源利用成为土工材料或作为填埋处置的预处理手段能够解决污泥处理中的一系列难题。开发高效污泥固化剂是该处理过程的关键。
A series of problems in sludge treatment can be solved by using sludge as a resource through solidification treatment technology to become geotechnical materials or as a pretreatment means of landfill disposal. The development of high efficiency sludge solidifying agent is the key of this treatment process.
