Description

BACKGROUND OF THE INVENTION 1. Field of the Invention [0001] The present invention relates to a double-type screen device installed in a high-

[0001] The present invention relates to a cube-type valve block device installed in a double-type screen device installed in an excellent purification apparatus, and more particularly to a cube-type valve block apparatus provided with a third screen on the inlet side of the main body, A first screen is provided on the upper side of the second screen and the foreign matter in the rainwater flowing through the inlet is purified in various stages through the first screen to the third screen, The efficiency of the filtration apparatus is increased by removing a certain amount of foreign matter, and thus the purified water can be utilized as the river water, thereby providing a practical double-screen apparatus.

Currently, the world's water shortage is a major issue in many countries, and Korea has also come to a stage where it can not be neglected. In order to solve this water shortage problem, we are looking for efficient water management, In fact.

Therefore, a variety of methods have been developed for efficiently using the natural rainfall to solve the water shortage phenomenon.

However, since such rainwater is exposed to various pollutants in the atmosphere and is discharged downward including the rainwater, it is also impregnated with various contaminants along the river surface, so that the pollutants contained in such rainwater are removed, It is necessary to have an excellent purification facility.

Generally, pollutants include point pollutants emitted from point sources such as life good, industrial wastewater, and livestock wastewater, and pollution sources such as agricultural land, pasture land, forest land, construction site, mine, logging ground, waste treatment plant, garbage Discharge areas, such as landfills, urban areas, roads and industrial sites, can be divided into nonpoint pollutants emitted from a wide range of nonpoint pollution sources.

As such, pollutants emitted from pollution sources are distributed in various forms such as heavy metals, pathogenic microorganisms, organic compounds, radioactive substances, toxic substances and other salts. These pollutants are usually washed with rainwater in rain, and they are poured into public water bodies such as rivers, inland waters, and lake waters along with rainwater, causing water pollution. In addition to the destruction of the ecosystem, It gives great harm.

On the other hand, among the above-mentioned pollutants, the discharge point is clear, and in the case of the limited point pollutants, a separate purification device or a wastewater treatment facility is installed in a home, a factory, an livestock farmhouse, In the case of pollutants, the emission area is wide and remains mostly on the surface of the ground, and it becomes a major cause of water pollution due to rainwater and rainwater, which flows into public water areas such as rivers,

Particularly, in the case of non-point pollutants, since it flows into public water bodies or ground water such as rivers, inland waterways, and lake water along with rainwater falling during the early rain particularly in the case of rain, the initial rainwater containing non-point pollutants is discharged into rivers, It is most important that you do not pour in the public waters or underground water without being purified.

As a technique for purifying the above-mentioned contamination source, particularly the initial storm containing the non-point source, a fixed screen such as a coarse screen and a fine screen has been installed in the conventional superior purification treatment method. However, If the clogging phenomenon occurs due to the impossibility of manpower placement, the entire apparatus is insoluble.

In addition, in order to remove sediments, a storage tank or a similar weir or a weir wall is installed to treat the sediments through a water infiltration function, the water is accumulated in the storage tank and the purification treatment apparatus even after the rain is over, And the odor is generated, and thus the apparatus for purifying treatment is practically turned into a pollution source.

In addition, in the case of an early storey treatment apparatus using filtration system and adsorption system, backwashing is not possible and the efficiency of the purifier is reduced or its life is shortened.

In order to solve the above-mentioned problems, Korean Patent Registration No. 10-0779513 discloses an inflow port for allowing initial rainfall to be introduced during rainfall. A pretreatment tank provided to filter contaminants and solids from the initial runoff flowing through the inlet; A filtration tank provided at a lower portion of the pretreatment tank so that contaminants and solids are separated through the pretreatment tank so that the initial storm containing fine particles can be filtered; And a water flow derivative provided at the center of the inside of the filtration tube and provided with fine particles containing fine particles discharged through the pretreatment vessel to be filtered and classified by a rotational force .
