Method and covering material for in-situ treatment of polluted bottom mud
The invention discloses a method and a covering material for in-situ treatment of polluted bottom mud. The method for in-situ treatment of polluted bottom mud comprises the following steps: a supporting structure barrier layer and a protective layer are sequentially laid on the surface of the polluted bottom mud, and the supporting structure barrier layer is formed by mixing aggregate and a sealing substance and then interacting with water; the aggregate is natural mineral; and the sealing substance is natural clay, sepiolite, attapulgite or kaolin. The covering material comprises the aggregate and the sealing substance, and the aggregate is the natural mineral; and the sealing substance is natural clay, sepiolite, attapulgite or kaolin. The bottom mud and the water body are efficiently isolated, so that all types of pollutants such as organic matters, nitrogen, phosphorus and heavy metals cannot be released to the water body, and the purpose of in-situ treatment of the polluted bottommud is achieved.
本申请公开一种用于污染底泥原位治理的方法及覆盖材料，用于污染底泥原位治理的方法包括：在污染底泥表面依次铺盖持力结构阻隔层和保护层，所述持力结构阻隔层由骨料与密封物质混合后遇水相互作用形成；所述骨料为天然矿物；所述密封物质为天然粘土、海泡石、凹凸棒或高岭土。覆盖材料，包括骨料和密封物质，所述骨料为天然矿物；所述密封物质为天然粘土、海泡石、凹凸棒或高岭土。本申请将底泥和水体进行高效隔离，使得有机物、氮、磷、重金属等所有类型的污染物均无法向水体释放，以达到污染底泥原位治理的目的。
