Description

TECHNICAL FIELD [0001] The present invention relates to a simple filtration apparatus for filtering and discharging water used in a water culture plant,

More particularly, the present invention relates to a simple filtration apparatus for water-membrane cultivation, and more particularly, to a method and apparatus for filtration of a water membrane used for culturing a water membrane, which discharges the water membrane water used for cultivation of a water membrane through simple filtration or purification, To a simple filtration device.

Farming methods using greenhouses are continuously expanding, but international competitiveness is declining due to the decrease in productivity due to high oil prices and the increase in production costs. In particular, high value-added horticultural crops are essential for environmental conditions such as constant temperature and humidity, so that cooling and heating required for production and ensuring water resources of appropriate size are essential for farming.

The heating of greenhouses (greenhouses and glasshouses) using existing geothermal heat has the following problems by using groundwater.

(1) The amount of groundwater is limited by the use of groundwater, and in the case of large-scale complex, too much groundwater is developed, which causes the problem of depletion of groundwater.

(2) Contaminated groundwater flows into the water layer of the greenhouse, which causes pigmentation of iron hydroxide, blocking the sunlight as well as aesthetics, thereby inhibiting the growth of vegetation for photosynthesis.

(3) When the filter for reducing the pollution source is used, the effect is insignificant, and the maintenance cost is increased, and the function as the alternative energy is lost. In the present case, contaminated groundwater is used without filtration.

(4) A certain amount of groundwater is necessary for heating. In order to secure adequate groundwater, groundwater is used as groundwater due to direct influx of pollution sources. Groundwater temperature is lowered due to mixing of groundwater and rock groundwater. Effective heating is difficult to expect.

(5) The groundwater used for heating is contaminated soil and river by discharging it to the soil and the river, and it acts as a factor to reduce the productivity of summer rice field and field farming. On the other hand, it is impossible to reuse the groundwater used for heating, and due to the excessive use of groundwater during the winter season, the difficulties caused by depletion of water resources during the dry season in April-May are repeated every year.

(7) Development costs are increasing over time to ensure sustained groundwater resources.

On the other hand, the conventional air-cooling type air-cooling method has a disadvantage in that it is difficult to maintain an appropriate temperature compared with the power-consuming method by the air-cooling method by the inflow and outflow of outside air,

An example of how to overcome such problems has been disclosed in Korean Patent Application No. 10-2008-0121918, entitled " Hydrothermal System Cooling & Heating System Using Groundwater Heat. &Quot;

Background Art [2] In the related art, a circulation heating medium injector for flowing a liquid heating medium, which is heat exchanged with latent heat of groundwater, between an outer membrane and an inner membrane to form a water film, And a collector for collecting the liquid heating medium.

An aeration facility house in which internal cooling and heating are performed by the water film; At least one " U " -shaped heat exchange pipe inserted into at least one of the at least one groundwater hole to cause heat exchange with the heat exchange liquid heating medium flowing in the inside and the groundwater outside the pipe; A supply pipe connected between the outflow path side of the 'U' type heat exchange pipe and the circulating heat medium injector for supplying a liquid heat medium that is heat-exchanged with the latent heat of the ground water, and a supply pipe connected between the collector and the inflow path side of the U- And a recovery pipe connected to the U-shaped heat exchange pipe for recovering the collected liquid heat transfer medium and introducing the recovered heat medium into the U-shaped heat exchange pipe. Shaped heat exchange pipe and a liquid heat medium which is heat-exchanged by the circulating heat medium injector and which is heat exchanged through the 'U' shaped heat exchange pipe, is supplied to the outflow path side of the 'U' type heat exchange pipe or the supply pipe path Circulation pump; And a storage tank that is provided on the return pipe and collects and stores the recovered liquid heating medium and supplies the stored liquid heating medium to the 'U' shaped heat exchange pipe side.

On the other hand, a large amount of menstrual flow is constantly needed to grow the water. In order to do this, the groundwater must be continuously pumped. Therefore, pumping of groundwater may cause cavitation in the ground, which can cause problems such as sinking and sinkholes. When the groundwater is exhausted, it is necessary to search for new groundwater or to use general water to grow water. Cost problems may arise.

In addition, not only the additional cost is required to keep the water temperature of the water film constant but also the environmental pollution may occur when the water used for the water film cultivation is discharged without purification treatment such as filtration.

The artificial turf 222 may be installed to shield the upper surface of the first filling material 210 to filter the foreign substances while moving the water film.

Artificial turf (200) is one of the specially used landscape materials. It is a grass made of synthetic fibers and is a substitute for artificial turf with a shape of grass. Since its first production in the United States in 1956, it has been used primarily in sports arenas.

It can be used in indoor gardens where it is impossible to grow grass, or in open-air areas such as polar regions where north-facing high-rise buildings with very limited sunshine time are available. The main materials are polyvinylidene chloride, polyethylene, polypropylene, and nylon.
