Description

TECHNICAL FIELD

[0001] The present application relates to the technical field of cyanobacteria treatment, in particular to a ship-mounted water bloom cyanobacteria collecting device. BACKGROUND

[0002] The problem of cyanobacterial bloom in lakes and reservoirs is a worldwide problem in water environment protection. With the aggravation of lake and reservoir eutrophication, the problem of cyanobacterial bloom has become an important ecological and environmental problem that needs to be solved in many lakes and reservoirs. The outbreak of cyanobacterial bloom can cause water oxygen deficiency, and the peculiar smell produced by the serious accumulation of water bloom can affect the senses of the surrounding residents. In addition, the release of algal toxins after the death and decay of water bloom cyanobacteria can affect water safety, and the outbreak of cyanobacterial bloom can also affect the healthy growth of aquatic organisms such as fish, aquatic plants and benthic animals.

[0003] At present, the main treatment method for cyanobacterial bloom in large water area of lakes and reservoirs is a mobile ship-mounted water bloom cyanobacteria collecting device. This mobile ship-mounted water bloom cyanobacteria collecting device is a method of integrating cyanobacteria salvage, algae water separation, and algae residue dewatering treatment units on an integrated ship. The algae water separation and algae residue dewatering units are the core process units of this method. For lakes and reservoirs where cyanobacterial bloom frequently occurs and the degree of water bloom is large, the mobile ship-mounted water bloom cyanobacteria collecting device must have strong algae-rich water treatment capacity and high algae water separation efficiency. Therefore, a large number of manpower and material resources have been spent on the development of large-scale biomimetic stacked screen filtration, drum filtration, and track-type filtration processes. In order to maximize economic benefits, lakes and reservoirs where cyanobacterial bloom frequently occurs and the degree of water bloom is large often purchase one to several integrated algae removal ships for annual water bloom cyanobacteria treatment and disposal. However, for some lakes and reservoirs where cyanobacterial bloom occasionally occurs and the degree of water bloom is small, it is not suitable to treat and dispose of cyanobacterial bloom by purchasing an integrated algae removal ship, and some simple, easy-to-operate, and relatively high-efficiency algae water separation devices or facilities should be configured.

[0004] Therefore, there is an urgent need for a simple ship-mounted water bloom cyanobacteria collecting device to solve the problem of occasional and small-degree cyanobacterial bloom. SUMMARY
