摘要

针对污泥固化材料种类繁多，各种材料互相组合时对固化污泥强度所起作用不明确问题，通过正交试验，研究常用的硅酸盐固化材料、碱性固化材料和黏土系辅助材料共同组合时对固化污泥强度的影响规律。结果表明，常用的各种系列污泥固化材料中硅酸盐固化材料和碱性固化材料对固化污泥强度形成起主要作用，碱性固化材料对固化污泥早期强度的形成具有重要作用，硅酸盐固化材料的作用到后期会明显的表现出来，黏土系辅助材料在添加后主要起系数和构建无机骨架的作用。

Abstract

Lots of sludge solidifying materials are used for sludge treatment

but the role of every material is not clear. The orthogonal test is carried out to optimize materials and reveal the influences of Portland solidification materials

alkali solidification materials and clay mineral materials. Test results show that the Portland solidification material and alkali solidification material play a major role in solidified sludge. Basic materials provide early strength for solidified sludge Portland solidification material provides the latter part strength. The clay mineral materials can construct skeleton to form monolithic body.
