| 摘 要： | 对采用不同石灰配比改性自来水厂污泥进行一系列室内土工试验，考察其改性后土性变化规律，研究改性后作为垃圾填埋场覆盖材料的可行性，探讨了合适的改性方案。初步认为按照一定泥灰比改性后的自来水厂污泥可作为覆盖材料的废弃物，并且能有效减少热收缩性。

| Abstract: | In order to investigate the probability of utilizing improved waterworks sludge that is mixed with certain proportion of limestone as covering material in landfill, series of experiments are accomplished and property changes are compared with original waterworks sludge. Preferable proportion of mixture is discussed. According to the test results and analysis, improved waterworks sludge meets the permeability requirement of landfill covering and its contraction ratio is reduced significantly at the same time. |
