Description

The Water Quality Control Facilities

The present invention relates to a water purification device, and more specifically, consisting of a contact tank built in the lower portion of the bottom of a river or a lake, a water flow guide wall and a biofilm carrier filled in the contact tank, and do not require a separate site for purification. The present invention relates to a water purification device having excellent efficiency and stable purification of rivers or lakes.

The water purification system for purifying polluted rivers includes biofilm carriers that can decompose contaminants by attaching and growing microorganisms on the surface, floating floating type, side stream type, riverbed protrusion type, and riverbed laying. Type and the like.

As an example of the floating type, Korean Patent Registration No. 10-0566785 (announced on March 27, 2006) is connected to a biofilm fixing panel having a filter medium capable of attaching and growing microorganisms, and is connected to a biofilm fixing panel, and changes according to the water level. It is coupled to the floating and accompanying body and the biofilm fixing panel, which provides the floating force for vertical movement of the biofilm fixing panel, and prevents the biofilm fixing panel from detaching from the accompanying board, and also the top and bottom of the biofilm fixing panel. There has been described a configuration including a levitation guide device for guiding the movement route.

In addition, the side stream (Side Stream) type of water purification device, by securing a separate site next to the river is installed a contact tank filled with the biofilm carrier, and after the inflow and purification of the stream water is sent back to the stream. Therefore, in order to introduce the river water into the contact tank, a water barrier facility and an inflow passage must be installed at the bottom of the river, thereby increasing the facility cost.

In addition, water gates are installed at the inlet of the contact tank, and when the water level rises during the flood level or the rainfall, the inflow should be blocked, so maintenance is cumbersome and the water purification function cannot be performed at the time of blocking the inflow. In particular, since it takes a separate site to install the contact tank is difficult to secure the site and difficult to select a location.

The riverbed water purification device is mainly in the form of a fence filled with crushed stone by building two walls in parallel and stacking them so that the slit-shaped openings are formed by separating the rod-shaped members at regular intervals and blocking both ends thereof. It is built long along the flow direction of river water at the bottom of the riverbed where the pollutant is introduced. And the river water flowing through the slit-shaped opening passes through the crushed stone layer filled in the crushed stone, and is brought into contact with the biofilm for adhesion and proliferation to the crushed stone. Since the crushed stone is filled with a large particle size, the surface area that the microorganism can adhere to is small, and accordingly, the purification efficiency is low.

In addition, it is installed by protruding a wide fence form on the riverbed, which may be an obstacle to the flow of river water, and may be lost or flooded during the high-speed flood. In particular, during low water dry season, most of the crushed stone layer is exposed and dried on the surface of the water, thus preventing the growth of microbial adhesion and losing its function as a carrier. Therefore, there is a problem that the purification function is lowered during the dry season when the necessity of the purification is deteriorated due to the increased pollution.

The riverbed water purification device is a biofilm carrier placed on a bed, and among them, for example, a biofilm carrier formed by adhering fine aggregates, such as gravel or crushed stone, having a particle diameter of 10-20 mm to a sphere having a diameter of about 100 mm in diameter, It can be installed at the bottom and configured to purify the water quality by the contact of river water and biofilm. Therefore, there is an advantage of not installing a separate contact tank, but when the flow rate is increased due to rainfall or flooding, there is a problem that the carriers are trickle and lost due to rapid water flow. On the other hand, since it is installed in a large area, it is difficult to install a net to prevent loss. In addition, since the bed laying biofilm carrier is thinly installed in a relatively large area of the bottom of the bedbed, the pores are closed by buried in the deposited sand and nito, and there is a problem of losing its function as a biofilm carrier.

The present invention has been made to solve the above problems, does not require a separate site, water and facilities, water barriers, biofilm carriers are not lost or buried, easy to maintain, smooth river water flow, flood The present invention relates to a water purification system having excellent river purification capability even during the dry season.
