The invention relates to a bottom mud collecting device. The bottom mud collecting device comprises an accommodating box, a turbulent flow assembly, an interception assembly and floating mats, wherein the two sides of the outer wall of the accommodating box are each connected with one floating mat, the floating mats are used for floating on the water surface of a river, the accommodating box is arranged at the bottom part of the river, and the floating mats are used for positioning the bottom mud collecting device; the top part of the accommodating box is provided with an inlet for river water to enter, so that suspended bottom mud in the river water entering the accommodating box is deposited in the accommodating box, the suspended bottom mud in the river water is further collected, and water eutrophication caused by phosphorus release due to suspension of the bottom mud under disturbance is avoided; the turbulent flow assembly is arranged in the accommodating box and used for preventing water in the accommodating box from being disturbed, so that the situation that bottom mud deposited at the bottom part of the accommodating box is disturbed by water flow to suspend again and release phosphorus after water disturbance is avoided; and the interception assembly is connected to the accommodating box, the interception assembly can block water flow to reduce the speed of the water flow and avoid water disturbance, and the interception assembly is provided with a plurality of adsorption holes which can adsorb and collect suspended bottom mud in river water.
Description
technical field [0001] The present disclosure relates to the technical field of water conservancy and ecology, and in particular to a sediment collection device. Background technique [0002] Sediment is usually a mixture of clay, silt, organic matter and various minerals, which is formed by depositing at the bottom of a water body after long-term physical, chemical and biological actions and water transport. [0003] The sources of phosphorus in rivers and lakes can be divided into exogenous phosphorus and endogenous phosphorus. At present, the input of exogenous phosphorus has been greatly controlled, and the release of endogenous phosphorus has become an important source of water eutrophication. Due to the impact of the river entering the reservoir or the blowing of wind and waves, the sediment at the bottom of the river and lake will be disturbed, and the sediment deposited at the bottom of the river and lake will be resuspended, resulting in the release of endogenous ph...
