摘要
为衡量水泥和混凝土材料,在利用粉煤灰分别与垃圾焚烧灰、电镀污泥、城市污水河底泥、建筑垃圾、建材废料、电池废渣、污水处理厂污泥等配制成的复合废弃物的过程中,对其中的重金属元素的固化程度,通过模拟真实状况的浸出试验对混凝土材料中重金属离子的浸出进行了的检测。考察了水泥和混凝土材料在利用废弃物的同时对环境保护所起的作用,找到了除电池废渣、污水处理厂污泥组成的废弃物以外,其他废弃物中的有害金属元素得到理想的固结有效降低环境污染的固结方案,为进一步通过调整废弃物掺加比例、选择性掺加增强强度的组分、重新调整彼此相适应的废弃物种类,从而考察水泥与废弃物之间的作用机理,重金属离子在水泥及浆体中的存在形态,探求试块强度与离子浸出之间的关系。
In order to measure cement and concrete for the use of fly ash in MSW respectively with ash, electroplating sludge,the urban sewage river sediment, construction waste residue, building materials, waste and sewage sludge of a compound waste as the process of heavy metal elements, the curing degree, the real condition can be simulated through leaching experiment of concrete material leaching of heavy metal ion in the test. The cement and concrete system using waste materials in protecting the environment, can effectively reduce the environment pollution. Consolidation plan by further adjusting the mixing proportion, the intensity of each type, then sums up more feasible scheme.
