摘要

淤泥固化技术是淤泥资源化利用的一个重要方法，而有机质对淤泥固化效果的影响是淤泥固化技术研究中的重要课题。在淤泥固化的试验研究中发现有机质含量对淤泥固化的效果有着显著影响。通过对不同有机物含量的固化试验揭示了该种影响的规律，发现淤泥中的有机质存在着一个极限含量4.3 %，当超过这一极限含量后，有机质量的增加不再对固化效果产生更大的影响。根据这一研究结果，提出了对于高有机质淤泥采用水泥-石膏进行固化的方法。

Abstract

Solidification technology is an important way for reuse of dredgings; the influence of organic matter on the effect of solidification is a significant problem needs to make clear. Through laboratory study

a remarkable influence of organic matter content on dredging solidification effect was discovered; the relationship of organic matter content and unconfined compressive strength of solidified dredging was made clear; a critical organic matter content 4.3 % exists in dredging

when the organic matter content higher than the content

the adding of organic matter does little influence on solidification effect. According to this principle

a cement-gypsum solidification method is proposed to solidify high organic matter content dredgings.
