Simple and efficient blue-green algae group salvaging device for aquaculture pond

Abstract

The invention belongs to the technical field of blue-green algae group salvaging and particularly relates to a simple and efficient blue-green algae group salvaging device for an aquaculture pond. Thedevice comprises a filter drum, the wall of the filter drum is provided with a plurality of water inlets, and water inlet regulating mechanisms are arranged on inner sides of the water inlets. A plurality of anti-sinking float balls are mounted on the upper portion of the filter drum, a plurality of hanging ropes are suspended on the bottom surface of the filter drum, and the lower end of each hanging rope is connected with a balancing weight fixed to the bottom of the pond. A first drain pipe is inserted into the bottom of the filter drum, an outlet of the first drain pipe is connected witha water pump, an outlet of the water pump is connected with a second drain pipe, an outlet of the second drain pipe is communicated with a filter tank filled with a filter medium, and the bottom of the filter tank is provided with a drainage structure. By the simple and efficient blue-green algae group salvaging device, problems of extensiveness, low salvaging efficiency and high operating difficulty in aquaculture pond blue-green algae group salvaging in the prior art can be solved.

Description

technical field

[0001] The invention belongs to the technical field of cyanobacteria colony salvage, and in particular relates to a simple and efficient salvage device for cyanobacteria colonies in culture ponds. Background technique

[0002] The high-density and intensive aquaculture model has promoted the eutrophication of aquaculture water in my country, which has led to frequent occurrence of cyanobacteria blooms in aquaculture ponds, especially in resource-induced water shortages. area is more serious. The harm of cyanobacteria bloom to freshwater aquaculture is mainly reflected in the following four aspects: First, Microcystis is a prokaryote with photoautotrophic ability, which can quickly occupy an absolute advantage in the aquaculture ecosystem and destroy the balance of the aquaculture ecosystem Secondly, cyanobacteria blooms easily lead to large fluctuations in the pH value and dissolved oxygen content of the aquaculture water, which seriously threaten the surviva...
