Embodiment 1

[0020] Embodiment 1: be used for the covering processing of lake sediment

[0021] Such as figure 1 As shown, the structural system of the present invention is set, by setting the laying system of covering film 5 and the conveying system of filler 14 on board; One end of the film 5 is covered to the bottom surface 1 of the river and lake by two guide wheels 4 and a spreading wheel 2 in turn; the filler 14 is placed on the conveyor belt 10 by the forklift 15, and the filler 14 is transported to the stern by the rotation of the reel 8 , and then sprinkled on the cover film 5 laid on the bottom surface of rivers and lakes through the material guide cylinder 6;

[0022] The spreader wheel 2 is connected with the guide wheel 4 by a telescopic rod 3. The spreader wheel 2 weighs 15kg, and the stretching force of the telescopic rod 3 is 0.3 times the weight of the spreader wheel 2. The maximum telescopic length is greater than the depth of rivers and lakes by 1m.

[0023] The guide ...

Embodiment 2

[0028] Embodiment 2: be used for the covering treatment of park bottom mud

[0029] Such as figure 1 and figure 2 As shown, the laying system of covering film 5 and the delivery system of filler 14 are made and installed on the ship; The weight is 0.6 times, and the maximum telescopic length is greater than the depth of rivers and lakes by 2m.

[0030] Guide wheel 4 and material guide cylinder 6 are fixed on the ship, and material guide cylinder 6 adopts plastics to make, and the inner clear width 300mm of making, length equals the width of covering film.

[0031] The filler 14 on the conveyor belt 10 is evenly spread through the spreader 9. The spreader 9 is made of steel plate with a thickness of 30mm and a width of 300mm. The steel plate is processed into an arc shape, and two steel chains are used to connect with the vertical pole. , The two steel chains form an angle of 45°.

[0032] Conveyor belt 10 is parallel to the water surface, and reel 8 and film reel 12 are f...

Abstract

The present invention discloses a cover treatment method for reducing the release of river-lake sediment pollutants. According to the cover treatment method, the paving system of a cover film (5) and the conveying system of a filler (14) are arranged on a ship, wherein the paving system of the cover film (5) is characterized in that the coiled cover film (5) is placed on a film coiling drum (12) and one end of the cover film (5) is covered on the river-lake bottom surface sequentially through two guide wheels (4) and a paving wheel (2), and the conveying of the filler (14) is characterized in that the filler is placed on a conveying belt (10) through a crane (16) or a forklift (15), the filler (14) is conveyed to a material guide drum (6) through the rotating of a rolling wheel (8) and then is sprinkled on the cover film (5) covered on the river-lake bottom surface, and the power source of the conveying belt is completed by making the power motor (11) sequentially drive a motor (13) and the rolling wheel (8). The cover treatment method of the present invention is suitable for the river-lake water regions with different depths, and has advantages of rapid construction, good quality, and significant environmental benefits.

Description

technical field [0001] The invention relates to a covering treatment method for reducing the release of river and lake sediment pollutants, belonging to the field of environmental ecological engineering. Background technique [0002] The continuous release of river and lake sediment pollutants aggravates river pollution. In order to reduce the impact of river and lake sediment on groundwater, it should be treated. At present, the bottom mud treatment of rivers and lakes is mainly based on bottom aeration, covering and dredging technologies, but bottom aeration can only treat the bottom mud surface with a thickness of a few millimeters, and the treatment effect is not obvious, so it is rarely used at present; There are also many problems in the application, such as high cost, large footprint of the treated sediment and pollutants in the sediment that easily cause secondary pollution, etc., which cannot meet the requirements of large-scale treatment. In contrast, covering tec...
