Description

[0001] The present invention relates to a device for field cultivating algae,

The present invention relates to an apparatus for culturing algae in rivers and rivers, and more particularly to an algae culture apparatus in which air circulation is efficiently performed.

In recent times, green algae, which are proliferating in the summer in the eutrophic hoso and rivers, are occurring more frequently. Mass production of cyanobacteria can be problematic in terms of management of water source, protection of water ecological health, and improvement of landscape. As the social concern about the occurrence of green algae increases, the need for preventive algae management increases. Therefore, research on the causes of the algae and growth limiting factors is required. Conditions for the growth of algae include meteorological and hydrological factors such as water temperature, solar radiation and flow rate, and biochemical factors such as nitrogen, phosphorus, carbon, iron and silicon, and biological elements such as predation, competition, and hitting. Any of these conditions can be a limiting factor if under- or over-exploited, and efforts have been made to control the occurrence of algae by artificially controlling these factors.

Various types of photobioreactors installed in the interior of the land are being used as a culture facility for culturing microalgae. Such a culturing facility installed in the indoor of the land must be equipped with an artificial lighting means and a temperature control facility must be provided in order to maintain the temperature of the culture facility appropriately, so that the manufacturing cost is high, need. In addition, such a cultivating facility installed in the indoor of the land requires a large expense to expand the scale, and it is difficult to reflect the spatial restriction due to the need for a large space and the actual conditions of the algae generation site. Therefore, in order to understand the mechanism of the occurrence of algae, an on-site culture experiment should be carried out at the site where the algae occur. Therefore, there is a need for technologies related to the construction of large-scale culture facilities.

In this regard, Korean Pat. No. 10-1237039 (entitled "Phytoplankton Culturing Apparatus") discloses a culturing vessel filled with phytoplankton and pure seawater for culturing phytoplankton, and a culture vessel for supplying pure sea water to a culture vessel A filter unit and a stirring unit for stirring the inside of the culture container, wherein the culture container is installed in a floating device floating on the sea, and a part thereof is submerged in seawater so as to match the environment of the sea with the environment of the culture container And a culture system for culturing the phytoplankton. Specifically, the culture container has a cylindrical frame, a culture passage fixed on the frame and opened on the upper side, and a cover member provided on the upper surface of the frame to cover the upper surface of the culture container, An air passage through which outside air can enter and exit is provided between the upper end and the upper frame. That is, the upper surface of the cultivation barrel is fixed to the upper frame in such a manner as to be woven with wires. At this time, the wire is loosened to form a space between the culture passage upper frames.

However, since the air passage is formed in such a manner that the top surface of the culture container is woven into the upper frame by a wire, the space between the culture passage upper frames can not be formed sufficiently wide, It is difficult to control the air circulation smoothly inside the culture container.

In addition, a dome-shaped portion having a hemispherical shape is formed at the center of the lid member to collect solar light. However, this has a disadvantage of concentrating the light amount in a specific portion of the culture container, thereby creating a culture environment different from the actual conditions.
