A treatment system for severe eutrophication in lakes and bays

Abstract

Disclosed is a system for controlling the severe eutrophication of a lake bay, comprising a bottom-layer water pool (1), a pressure-regulating reservoir (16), a lift water gate (6), a fan-shaped water inlet channel (3), a water pump (8), a wind-solar complementary power supply system (25), an auto-control backwash system, and a micro / nano air bubble generator dual-machine linkage unit (24). The present invention can conveniently address the problem of reoxygenation of anaerobic water in the bottom layer of the lake bay while increase the water flow rate and self-cleaning capability of the lake bay water, thereby effectively controlling the eutrophication of the lake bay.

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...
