Abstract

The invention relates to a method for algae removal of aquiculture water by use of a high-voltage pulsed electric field and belongs to the technical field of aquiculture. The method adopts a specific process and such specific parameters as output voltage of 18-25 kv, pulse width of 12-20 [mu]s and pulse frequency of 50-80 Hz; then a generator is started up for circulating water treatment for 2-3 times, circulating treatment of aquatic water effectively breaks algae floccules and cell lethal, the algae removal ratio is 96-97 percent, and the algae control purpose is achieved; meanwhile, a coagulant (polyaluminium sulfate) and a sludge pumping machine are provided to realize algae body flocculation and sedimentation and withdrawal, and the algae removal ratio can be increased to 100 percent to the utmost extent; algae decomposition for algal toxin release is prevented, and the healthy environment of aquatic water is effectively guaranteed. The method provided by the invention is a physical method, is good in effect, most direct, free from secondary contamination and low in cost, can remove all algae and is very suitable for being applied to algae removal of aquiculture water.

Description

technical field [0001] The invention relates to a method for removing algae from aquaculture water. More specifically, the invention relates to a method for removing algae from aquaculture water by using a high-voltage pulse electric field, which belongs to the technical field of aquaculture. Background technique [0002] Cyanobacterial blooms have become a sign of eutrophic water bodies around the world, resulting in deterioration of water quality, damage to the structure and function of ecosystems, and the production of toxins, which have brought great harm to humans and aquatic animals. In recent years, harmful cyanobacteria blooms have occurred frequently in my country. According to statistics, 60% of lakes in my country are in a state of eutrophication, accompanied by the occurrence of algae blooms. The dominant species forming algal blooms was Microcystis aeruginosa. Large-scale algae outbreaks have seriously damaged the balance and stability of aquatic ecosystems, n...
