强酸溶液腐蚀条件下污泥固化体力学特性

Mechanical properties of sludge solidified body under strong acid corrosion condition

对在pH=1的硫酸溶液,pH=7的蒸馏水中浸泡后的不同配合比的污泥固化体进行三轴剪切试验,得到不同腐蚀条件下污泥固化体的力学强度特性。由此来筛选出更好的耐酸腐蚀的污泥固化体配合比。

In this paper, three-axis shear test is carried out on sludge solidified bodies with different mixing ratio af-ter soaking in the p H=1 sulfuric acid solution and p H=7 distilled water, and the mechanical properties of the solidi-fied sludge are obtained under different corrosion conditions, so as to screen out the better acid-resistant sludge so-lidification ratio.
