Water body cyanobacteria treatment device

Abstract

The invention discloses a water cyanophyta treatment device which comprises a collection device, a separation device and a pipeline, wherein the collection device comprises a floating body which is provided with an inner cavity of which the upper part is opened; the side wall of the inner cavity is provided with a water inlet; a grid is arranged in the water inlet; meanwhile, a collection cylinder is arranged on the lower part of the inner part of the inner cavity; the lower end of the pipeline communicates with the lower part of the collection cylinder; the separation device comprises a separation cavity and a water pump; the upper part of the separation cavity is provided with a vertical partition plate; a space is formed between the partition plate and the bottom of the separation cavity; the separation cavity is divided into a collection cavity and a water outlet cavity by the partition plate; the upper end of the pipeline communicates with a water inlet end of the water pump; a water outlet end of the water pump is connected with the collection cavity; the upper part of the collection cavity is provided with a cyanophyta outlet; and the middle part or the lower part of the water outlet cavity is provided with a water returning opening. The water cyanophyta treatment device has the advantages that cyanophyta on the water surface can be collected and separated well, and the water cyanophyta treatment device is small in size.

Description

technical field [0001] The invention relates to the technical field of water treatment equipment, in particular to a water body cyanobacteria treatment device. Background technique [0002] When a cyanobacteria bloom occurs in a water body, chemical treatment and mechanical salvage treatment are generally adopted. The so-called chemical treatment refers to the artificial injection of chemical agents to kill algae or inhibit the growth of algae, so that the number of algae can be reduced or effectively controlled in a short period of time. This treatment method has quick effects and is suitable for emergency treatment. However, when the concentration of chemicals in the water drops to a certain level, algae will continue to reproduce, and long-term use of chemicals will cause water pollution and accumulation of poisons. The so-called mechanical salvage mainly refers to the use of cyanobacteria salvage ships to collect and salvage cyanobacteria in lakes and rivers. At the sam...

This treatment method is effective and suitable for emergency treatment, but when the concentration of the chemical in the water body drops to a certain level, algae will continue to reproduce, and long-term use of chemical agents will cause water pollution and accumulation of poisons

The so-called mechanical salvage mainly refers to the use of cyanobacteria salvage ships to collect and salvage cyanobacteria in lakes and rivers. At the same time, the collected cyanobacteria are filtered and dehydrated on board, and then directly dried into algae cakes. However, cyanobacteria salvage ships are generally used in lakes and large areas. River course, and time-consuming and labor-intensive, the cost is high
