Algae removal method and movable algae removal platform suitable for river channel type water body

Abstract

The invention provides an algae removal method and a movable algae removal platform suitable for a river channel type water body. The algae removal method and the movable algae removal platform suitable for the river channel type water body utilize a ship body as a carrier, adopt an ultrasonic algae removal instrument, a microfiltration machine, a self-suction type spiral stirring aeration machine and a rotary type algae salvage machine for matching, achieves ultrasonic removal, mechanical salvage, algae-water separation, and functional combination of water body oxygen enrichment and air floatation to restrain the growth of the algae in water, the irradiation frequency of ultrasonic waves is A which equals to 20-50 kHz, the irradiation distance is B which equals to 0.5m, and the irradiation time is C which equals to 5min. According to the algae removal method and the movable algae removal platform suitable for the river channel type water body, the algae body cell air bags and cell ectocrine are affected to further affect the agglomeration effect of the algae in water so that the removal of the algae is achieved. Compared with a stationary type ultrasonic algae removal method, rapid and accurate function can be carried out on the entire research water area. The movable algae removal platform eliminates the heavy workload of algae salvage for workers when a water bloom occurs, causes smaller economic loss compared with that caused by eutrophication of the water body, is suitable for water quality characteristics of secondary rivers in the Three Gorges Reservoir Region, and has a good demonstration effect.

Description

technical field [0001] The invention relates to the prevention and control technology of eutrophic water body, in particular to a method for inhibiting algae and removing algae and a multifunctional mobile algae inhibiting and removing algae platform suitable for river-type water bodies. [0002] Background technique [0003] With the acceleration of social industrialization, human beings have accelerated the eutrophication process of lakes and reservoirs in industrial and agricultural production and daily life. The extreme manifestation is the outbreak of algal blooms, which will cause serious harm to the water environment and destroy Ecological balance, and even loss of water use function, resulting in significant losses of water resources, water environment and regional economy. According to the data provided in the "China's Green National Economic Accounting Research Report (2004)", the environmental cost of my country's water pollution in 2004 was 286.28 billion yuan. ...
