Description

Integrated device for mechanical catching, filtering and collecting of microcystis

Technical Field

The invention relates to the technical field of microcystis catching devices, in particular to a mechanical microcystis catching, filtering and collecting integrated device.

Background

In recent years, due to the overuse of pesticides and fertilizers and the random discharge of domestic sewage, the pollution of lakes and rivers is increasingly serious, and microcystis is proliferated in water bodies in large quantities. The green tide and red tide can occur during the large-scale propagation of the microcystis, which harms the natural environment and influences the growth and propagation of fishes.

At present, methods for removing microcystis in lakes and rivers mainly comprise a chemical method and a mechanical catching method, if the chemical method is adopted for removing the microcystis, water pollution is caused, so that the chemical method is not adopted for removing the microcystis at present, the mechanical catching method is generally that a string bag is manually held by hands for catching or a water pump is adopted for pumping, the manual holding method of the string bag by hands has more personnel investment, the catching efficiency is low, the labor cost is high, and the water below the microcystis pumped into the pump for catching by the pump, so that the water content of the caught microcystis too high, and the catching efficiency is difficult to improve.
