specific Embodiment approach 1

[0031] Specific implementation mode one: mobile air floating platform device such as figure 1 , figure 2 , image 3 and Figure 4 As shown, the device for removing algae in the eutrophic water body by the mobile air flotation platform of this embodiment is composed of an air flotation separation collection system, a floating algal residue collection system, an algal residue dehydration system C, a power system D and an ultrasonic generator array E composition;

[0032] Wherein, the air flotation separation and collection system is composed of two parallel buoys 1, an algae residue collection bucket 2 and a microbubble generation system A1; the two parallel buoys 1 provide buoyancy support, and the two parallel buoys 1 are rigidly supported The columns are connected, the parallel buoys 1 are hollow, and each buoy is divided into storage spaces 1-2 and 1-3 through a cross-sectional partition in the middle of the parallel buoys 1. The microbubble generation system A1 is a pre...

specific Embodiment approach 2

[0045] Embodiment 2: The difference between this embodiment and Embodiment 1 is that the material of the parallel buoy 1 is stainless steel, aluminum alloy, plastic, glass fiber reinforced plastic, synthetic resin or polyurethane material, and the section shape of the parallel buoy 1 is different. Limit, the section of the parallel buoy 1 is surrounded by a combination of curved surfaces and planes, a single curved surface or a plane. Others are the same as the first embodiment.

[0046] The purpose of the parallel buoys 1 and its section type in this embodiment is to provide sufficient buoyancy support and draft, provide a relatively closed water environment for the air flotation process, and reduce running resistance in water.

specific Embodiment approach 3

[0047] Embodiment 3: The difference between this embodiment and Embodiment 1 or 2 is that: the microbubble positive charge modification agent dosing device 13 is set in the microbubble generation system A1, and the microbubble positive charge modification The medicament dosing device 13 is arranged on the operation platform 12, and the drug outlet of the microbubble positive charge modified medicament dosing device 13 is connected with the medicine inlet of the pressure dissolved gas tank 4 or the gas-liquid separation tank 16; The microbubble positive charge modifying agents added by the charge modifying agent dosing device 13 are metal coagulants, cationic surfactants, cationic polymers, chitosan or modified chitosan derivatives, and the dosage of the agents is 0.1mg / L~30mg / L;

[0048] If the micro-bubble generating system A1 is a pressurized dissolved air micro-bubble generating system, then the micro-bubble positive charge modifier is added directly or before the tank by u...

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...
