Description

TECHNICAL FIELD

[0001] The present application relates to the technical field of water body ecological restoration, in particular to a eutrophic water body ecological restoration system and method. BACKGROUND

[0002] Water eutrophication refers to the phenomenon that water contains too much nitrogen, phosphorus and other soluble nutrients, leading to rapid reproduction of algae and other plankton in the water, decrease of water dissolved oxygen, deterioration of water quality, and mass death of fish and shrimp and other organisms.

[0003] The common control method of endogenous nutrients in water eutrophication is physical method, chemical method and ecological management method. The chemical method generally uses chemical substances for flocculation, including various aluminum and iron salts, which can produce insoluble precipitates with phosphate, thereby reducing the content of phosphorus in water. When this method is used for treatment, the chemical substances for flocculation are directly sprayed into the water body for treatment.

[0004] For the related technology in the above, if the chemical substances are used alone for treatment, the water body will be rich in a large amount of precipitates, which is not easy to clean. If water is pumped through a filter for filtration, fixed-point pumping will result in small treatment range and low treatment efficiency. SUMMARY

[0005] In order to realize omnidirectional and efficient treatment of water eutrophication, and at the same time not to produce precipitates in the water, the present application provides a eutrophic water body ecological restoration system and method.

Through repeated operation, the filters at two ends of the inlet shell are cross-filtered, so that the cruise ship can carry more filters, and the time that the cruise ship can automatically and continuously treat the water body is prolonged.
