| titleOfInvention | Multifunctional sediment covering device |
| abstract | The utility model discloses a multifunctional sediment covering device, which is arranged between the upper water and the sediment and comprises a first covering layer, a second covering layer, a third covering layer and a fourth covering layer, wherein the first covering layer, the second covering layer and the third covering layer are sequentially distributed from top to bottom; the first covering layer is in contact with the overlying water and is used for adsorbing and removing nitrogen, phosphorus and heavy metals in the overlying water; the first covering layer is also used for controlling the release of nitrogen, phosphorus and heavy metals in the sediment; the second covering layer is used for adsorbing and removing the release of organic pollutants in the overlying water; and the second overlayer also serves to control the release of organic contaminants in the deposit; the third covering layer is used for recycling the first, second, fourth and fifth covering layers; a fourth overlayer for controlling the release of organic contaminants from the deposit; and the fifth covering layer is in contact with the sediment and is used for controlling the release of nitrogen, phosphorus and heavy metals in the sediment. The utility model discloses reduce endogenous pollutant's release, also reduced the risk of secondary pollutant release. |
