Embodiment Construction

[0018] Below in conjunction with example further illustrate the present invention.

[0019] The main body of the system for automatic suction and ecological treatment of river polluted sediment is a wooden waterwheel with a diameter of 320cm. Install 8 waterwheel blades at 45° on a wooden ring with an outer diameter of 60cm, an inner diameter of 10cm, and a width of 50cm. Each waterwheel blade is 120cm long, 50cm wide, and 5cm thick. 1cm thick activated carbon fiber is laid on both sides. A suction mud bucket is installed perpendicular to the paddle at each paddle top of the waterwheel, and the thickness of the suction mud bucket is 10cm, wide and 50cm, and deeply 20cm. The wooden ring is installed in the opening of the waterwheel bracket at the top of the waterwheel bracket through the waterwheel rotating shaft. The diameter of waterwheel rotating shaft is 10cm, and long is 120cm. The waterwheel support is an isosceles triangle support, the height of the waterwheel support...

Abstract

The invention discloses an automatic suction and ecological treatment system for polluted bottom sediments of rivers and belongs to the technical field of restoration of bottom sediments of rivers. The system is composed of a main-body waterwheel, a drainage trench and an artificial wetland, wherein the waterwheel mainly comprises eight waterwheel blades with same specifications, a waterwheel rotating shaft and a waterwheel bracket; and microorganism carriers are laid on the surface of each waterwheel blade, and the top end of each blade is provided with a sediment suction barrel. The waterwheel is driven to rotate through the flowing of the water body of a river, so that the sediment suction barrels at the top ends of the blades carry out the process of sediment suction, sediment discharge and sediment suction repeatedly, bottom sediments of the river are introduced in the constructed supported artificial wetland to carry out ecological restoration treatment, in such a way, the harm of polluted bottom sediments of rivers is reduced or disappears. The system disclosed by the invention has the advantages of no energy consumption, no required manual operation basically, no operation and management charges, capability of persistently removing sediments, good bottom sediment treatment effect, almost in-situ ecological restoration treatment, capability of not damaging the living environment of local benthos, and capability of achieving a positive effect on the self-cleaning of the water body of a river, and the like.

Description

technical field [0001] The invention belongs to the technical field of river bottom mud restoration, and in particular relates to an automatic suction and ecological treatment system for river polluted bottom mud. Background technique [0002] River ecological restoration technology refers to the use of comprehensive methods to restore the natural functions of rivers that have been lost or degraded due to human activities. It is a branch of ecological engineering and a technical means to give full play to the natural functions of rivers. , derived from the concept of "near natural river management project" first proposed in Germany. The goal of river ecological restoration is to restore the river ecosystem to the approximate state before it was destroyed, to form a river ecosystem with reasonable ratio of various biological communities, optimized structure, powerful functions and stable system, so as to ensure the dynamic equilibrium process of the river. At present, the te...
