Abstract

The invention belongs to the technical field of water environment treatment and discloses a biological mud collecting and desilting structure and an implementing method thereof. According to the technical scheme, a mud collecting tank is located at a bottom mud settled layer in the flow direction of an into-lake river and is perpendicular to the flow direction of the into-lake river; flow deflectors are arranged on the two sides, close to the into-lake river, of the front end of the mud collecting tank, each flow deflector and the flow direction of the into-lake river form an oblique angle, and the height range of the flow deflectors is between the lake river normal low water level and the lake river normal high water level; a flow blocking body is located at the rear end of the mud collecting tank and is perpendicular to the flow direction of the into-lake river, and the height range of the flow blocking body is between the lake river normal low water level and the lake river normal high water level; and a sealing body is arranged at the top in the mud collecting tank, and an observation facility capable of monitoring and measuring the settlement situation of bottom mud in the mudcollecting tank is arranged in the mud collecting tank. Through the biological mud collecting and desilting structure and the implementing method thereof, the bottom mud needing to be cleared can becontrollably restrained within a certain set range to settle, bottom mud pollution is effectively controlled, and regular repeated desilting construction can be implemented.

Description

technical field [0001] The invention relates to the technical field of water environment treatment, and relates to an ecological dredging technology and an implementation method for internal source treatment of lakes. Background technique [0002] Lake sediment is an important part of natural waters. It is not only the alternating zone of lake water-soil interface materials, but also the accumulation of heavy metals, organic matter, nitrogen and phosphorus, etc. that enter the lake. It releases nutrients to the overlying water body under the action of external factors such as wind, waves, and temperature. , causing water pollution and lake eutrophication, becoming an important endogenous pollution. The lake bottom sediment mainly comes from the lakeshore terrestrial sediment particles transported by rivers entering the lake, suspended particles in the water body, aquatic plants and algae residue deposits. The accumulative distribution and pollution characteristics of lake s...
