Embodiment

[0035] Refer to attached Figure 1-7 A cyanobacteria bloom collection, salvage, treatment and prevention method mainly includes a collection and salvage system installed on a cyanobacteria collection and salvage ship, and a cyanobacteria treatment and water bloom prevention system;

[0036] The salvage ship is mainly composed of a hull 1 and a control room 1-1 where the power and control systems of various systems on the hull are located.

[0037]The collection and salvage system is mainly composed of engine 2, driving drive shaft 4, diversion system 8, salvage belt 14, collection tank 18 and the like.

[0038] The engine 2 is fixedly installed on the hull base 15 of the hull 1 .

[0039] Furthermore, the power output by the engine 2 is driven by various belts, and finally drives the diversion system 8, the fishing belt 14 and other actions.

[0040] Further, the active transmission shaft 4 and the intermediate shaft 6 are fixed on the hull 1; the driven shaft 12 is fixed on...

Abstract

The invention relates to a cyanobacteria bloom collecting-fishing treatment and preventing method. The cyanobacteria bloom collecting-fishing treatment and preventing method specifically comprises thesteps that, a, as a hull advances, a cyanobacteria bloom collecting-fishing system installed on the hull performs continuous cyanobacteria fishing; b, the collected cyanobacteria are added into a screw extruder for extrusion dehydration, and the collected wastewater with different MC content is collected in stages; c, the wastewater collected in the early stage of extrusion is irradiated with ultraviolet rays of wavelength 238-254 nm for 5-10 minutes; and d, the dehydrated cyanobacteria enter a heating copper sleeve for heating and inactivation, and the subsequent treatment is even directly discharged into lake water for microbial degradation. The cyanobacteria bloom collecting-fishing treatment and preventing method has the beneficial effects that cyanobacteria bloom can be effectively collected and fished, efficient and low-cost treatment is carried out, and the occurrence and worsening of the cyanobacteria bloom are further contained.

Description

technical field [0001] The invention relates to a method for collecting, salvaging, treating and preventing cyanobacteria blooms, and belongs to the technical field of prevention and treatment of cyanobacteria blooms in the biological environmental protection industry. Background technique [0002] In recent years, with the rapid development of the economy, the problem of water pollution has become increasingly serious. Since the drinking water crisis caused by cyanobacteria blooms in Taihu Lake in 2007, cyanobacteria blooms have always attracted the attention of all walks of life. If the cyanobacteria are not cleaned up in time, the toxins produced will pose a fatal threat to aquatic organisms, and the death and decomposition of cyanobacteria will consume a large amount of oxygen. The lack of oxygen in the water body will destroy the normal food chain, threaten the safety of drinking water, and cause serious economic losses and social problems. [0003] Microcystins (MC) a...
