Governing system for severe eutrophication of lake bay

Abstract

The invention discloses a governing system for the severe eutrophication of a lake bay. The governing system comprises a bottom-layer pool, a surge tank, a lifting type water gate, a sector water inlet pipe, a water pump, a wind-solar hybrid power supply, a unique automatic control back washing system, a micro / nano bubble generator double linking unit; the self-purifying function of an integral lake bay is systematically designed; two dominating factors that hypertrophic bottom water of the lake bay lacks of dissolved oxygen and a lake bay water body is difficult to change are overcome. The invention provides a technical scheme with the advantages of high simplicity, high practicality, energy conservation, environmental protection and low construction cost; the endogenous self-purification ability of the lake bay is formed by establishing the long-term self-reoxygenation cycle, and the defects of a governing mode of diverting river water to control algae in lakes on a large scale are overcome. The technical scheme is combined with the governing mode of diverting the river water to control the algae in the lakes on the large scale, and a better governing effect is expected to be obtained.

Description

technical field [0001] The invention relates to an ecological management system, in particular to a severe eutrophication management system for lake bays. Background technique [0002] Many bays in the lake, due to the curved terrain, the water exchange cycle is longer than that in the middle of the lake, coupled with the push of wind and waves from the lake to the shore, it is often easier to produce and gather a large amount of algae, thus forming a heavily eutrophic area in the lake bay . From a certain point of view, it can be considered that whether the eutrophication in the lake bay can be completely controlled will be related to the success or failure of the whole lake treatment effect. This is a major issue that must be addressed in the governance process. [0003] In the heavily eutrophic bay area, the lack of dissolved oxygen in the bottom water of the lake and the difficulty in replacing the water body in the bay are the two dominant factors that form the severe...
