Impermeable material as well as preparation method and application thereof
The invention provides an impermeable material as well as a preparation method and application thereof. The preparation method comprises the following steps: S1, mixing chitosan, an organic matter and a microbial agent to obtain a mixture I; s2, performing dry mixing on the mixture I, bentonite, fly ash, silt and polyacrylate, and performing hydration to obtain a reticular mixture; s3, fermenting the net-shaped mixture to obtain the anti-seepage material. The bentonite, the fly ash and the silt are adopted as main raw materials for seepage prevention of the bottom layer of the coal gangue landfill, after the chitosan and the polyacrylate are added, the microbial agent is mixed, meanwhile, the organic matter can provide nutrients for microorganisms, the obtained seepage prevention material can maintain moisture while adsorbing heavy metal, and the seepage prevention effect is good. Pollution of underground water and soil caused by loss of the leaching liquid is reduced, and meanwhile pollutants are prevented from being transversely migrated to surrounding areas.
本发明提供了一种防渗材料、其制备方法及应用。其中，该制备方法包括：S1，将壳聚糖、有机质和微生物菌剂混合，得到混合物一；S2，将混合物一、膨润土、粉煤灰、粉土和聚丙烯酸盐进行干法混合后，进行水化，得到网状混合物；S3，将网状混合物进行发酵，得到防渗材料。本申请采用膨润土、粉煤灰、粉土作为煤矸石填埋场底层防渗的主要原料，并将壳聚糖、聚丙烯酸盐添加后，混入微生物菌剂，同时有机质能够为微生物提供养分，所得到的防渗材料在吸附重金属的同时能够维持水分，减少淋滤液的流失对地下水以及土壤所造成的污染，同时防止污染物横向迁移到周围地区。
