Device for removing algae in eutrophicated water body by mobile floatation platform and application method thereof

Abstract

The invention provides a device for removing algae in a eutrophicated water body by a mobile floatation platform and an application method thereof, relating to the technical field of environmental protection. The invention can effectively solve the problems of excess dependence on the ship hull, complex structure, high construction and operating cost, incapability of providing appropriate floatation separation environment, low utilization ratio of microbubbles, unideal separation efficiency and the like in the existing floatation ship alga removal device. The device is composed of a floatation separation system, a floating alga residue collecting system, an ultrasonic alga eliminating system, an alga residue dehydration system and the like. A microbubble modifier can be added into a microbubble generation system to enhance the sticking probability between the microbubbles and the alga cells. The device can implement in-situ separation and collection of alga cells in the eutrophicated water body, has an oxygenation aeration function, and can remove nutrient substances capable of inducing large-scale growth of algae to some extent. Besides, the device can be applied to the field of oil sludge separation and collection in a water body.

Description

technical field

[0001] The invention relates to a device for removing algae and a use method thereof, in particular to a device and a method for removing algae in eutrophic water bodies by a mobile air floating platform. Background technique

[0002] The eutrophication of lakes, reservoirs, rivers, and coastal areas has always been a key and difficult problem in the governance of my country's surface water environment system. Taihu Lake, Dianchi Lake, Chaohu Lake, Hongze Lake, Jiaozhou Bay, Bohai Bay, and the mouth of the Pearl River have all occurred Due to the explosive growth of cyanobacteria, there are still varying degrees of eutrophication up to now. The explosive growth of algae not only affects the landscape of the water body, but also causes the deterioration of the ecological environment of the water body, making it lose its self-purification ability. If eutrophic water is used as the water source, on the one hand, a large number of algae cells enter the water trea...
