Description

Technical Field

[0001] The utility model belongs to the technical field of pollutant disposal facilities, and in particular relates to an anti-seepage and anti-escape device for a temporary storage site used for mud phosphorus excavation. Background Art

[0002] Mud phosphorus refers to waste with no residual value generated during the production of yellow phosphorus. Landfilled and stored mud phosphorus will cause underground soil to be infiltrated and polluted, and the environmental risk is very high. In particular, the land where the mud phosphorus is stored no longer meets the conditions for other uses, and the mud phosphorus storage site must be excavated, cleaned, disposed of, and transformed. The excavated mud phosphorus is temporarily piled up at the construction site, and then loaded and sealed for transportation. Since the pile of mud phosphorus will infiltrate the site and also produce smoke, it will cause secondary pollution. The existing technology directly carries out anti-seepage transformation on the ground of the temporary storage site, which has a relatively large construction volume, is time-consuming and labor-intensive, and it is difficult to prevent smoke from escaping. For this reason, it is very necessary to develop a temporary storage site anti-seepage and anti-escape device for mud phosphorus excavation that does not require the modification of the site ground and is easy to install.
