Description

TECHNICAL FIELD [0001] The present invention relates to a micro-algae culture tank for micro-algae culture,

The present invention relates to an indoor / outdoor microalga culturing tank using a catching membrane and a prefabricated block, and more particularly, to a prefabricated block capable of injecting hot water and circulating the hot water to form a frame of a culture tank for culturing microalgae, Which is capable of culturing microalgae in a variety of environments without additional structure, and a microalgae culture tank for indoor / outdoor use using a prefabricated block.

In recent years, various efforts have been made to obtain various useful materials through microalgae and to industrialize them at home and abroad. These microalgae are known to have higher ability to absorb and reduce carbon dioxide, which is the main cause of global warming, compared to land plants.

On the other hand, reservoirs that are formed by various dams such as multipurpose dams are used as important water sources in Korea due to lack of water resources. However, due to rapid urbanization and industrialization, many rivers contaminated by domestic sewage, factory wastewater, As the water is used as a water source, more than half of the domestic appeals are eutrophicated or in progress.

In order to solve this problem, we are investing heavily in sewage treatment projects such as conversion of existing activated sludge process to advanced treatment process. However, domestic sewage has a very low organic matter content, which limits the effective removal of nitrogen and phosphorus, which are the causes of eutrophication. Recently, phosphorus chemical treatment has been introduced for effluent from wastewater treatment plants.

Here, even when the chemical tertiary treatment such as treatment water or flocculation in the biological treatment process, which is a general advanced wastewater treatment process, is carried out, the concentration of phosphorus in the effluent water is 0.5 to 1.0 mg / L, . In addition, as regulations on total phosphorus in sewage treatment plants have been strengthened, more than 200 billion won per year is used for chemical treatment of phosphorus. Secondly, there is a problem of chemical pollution caused by the use of chemical flocculant. It is urgent to present it to the solution.

In order to solve such a problem, an advanced treatment method of sewage water has been developed by using algae treatment for removing nitrogen and phosphorus from discharged water using the microalgae mentioned above. When nitrogen and phosphorus are removed by using microalgae, not only the treatment efficiency is higher than that of the conventional chemical treatment process, but also the treatment cost can be reduced, and it is possible to produce energy using the microalgae cultured in the process And so on.

Therefore, researches on high-density mass cultivation of microalgae and efficient and steady harvesting are actively conducted at home and abroad. However, in Korea, the four seasons are distinct, and depending on the species, there is a cold season which is below the normal optimum growth temperature of microalgae, so it is very difficult to produce and harvest continuously.

In addition, a large amount of energy is required to maintain a proper temperature for mass culture. To solve such a problem, the additional efficiency of the structure is low due to the increase in the production cost.

In general, the main factors affecting the growth of microalgae are the concentration of nutrients, light intensity, and temperature. Microalgae have different temperatures at which species can grow, and there are dead temperatures and optimum growth temperatures. Most microalgae can metabolize photosynthesis and cell division in the range of 15-30, and the optimum growth temperature is about 20 ~ 25. As the temperature increases in the temperature range below the optimum temperature for growth, microalgae tend to increase photosynthesis and cell growth. It is also known that at temperatures above the optimum growth temperature, the growth of microalgae is seriously inhibited. In most outdoor cultures, microalgae are often below the metabolic limit temperature range, and the production efficiency of microalgae may be affected not only by seasonal temperature differences but also by diurnal variation.

However, according to the prior art, microalgae culture was mainly cultured in an out door to commercialize. At present, the outdoor culture vessels are fixed to the ground in the form of an integrated bathtub using concrete or the like. Once installed, the culture vessels can not be changed or moved. As mentioned above, in order to maintain the proper temperature, There is a problem that a device for maintaining the temperature needs to be provided separately.

In order to solve such a problem, conventionally, there has been a method of controlling the temperature through a vinyl house facility. Temperature control using a greenhouse is a primary defense against sudden temperature fluctuations and seasonal temperature changes in the cultivation of a greenhouse, and a culture tank is installed inside a greenhouse. In this case, there is a problem that an expensive vinyl house facility is required. Especially, the vinyl house of tempered glass or transparent plastic is used as the outer appearance, the first temperature is controlled by opening and closing the side and the roof, and the second temperature is controlled by installing the large and cold air conditioner inside. Therefore, there is a problem that the facility cost is high and the operation cost is relatively large.

In addition, it is difficult to control the temperature with homeostasis. This is because the temperature difference between the culture medium in the culture tank and the inside of the vinyl house is significant and the temperature control inside the culture tank can not be rapidly progressed even if the temperature inside the vinyl house is changed. It is difficult to keep the temperature of the greenhouse constantly. Therefore, in order to keep the temperature of the culture tank at a constant level only by the temperature control inside the greenhouse, the additional cost is required.

Accordingly, there is an urgent need for a practical and applicable technology related to a microalgae culture apparatus capable of maintaining a proper temperature for growth of microalgae in various environments and facilitating size change and movement.
