Description

The adsorption and seperating method and apparatus of sludge on the ground under water}

The present invention relates to a sludge adsorption / separation method and sludge treatment apparatus for effectively suctioning and collecting sediment deposited on the bottom surface of a river, a lake, a harbor or a golf course pond.

Generally, untreated sewage or factory wastewater, industrial wastes, pollution dust, falling leaves or garbage can be deposited on the bottom of rivers, lakes, ports, or ponds, and are deposited on gravel or sand at the bottom. It is here.

Recently, as a part of improving the urban living environment in Korea, the Lake Park in Goyang Ilsan, Gyeonggi-do, has been used by citizens by making a large artificial lake with a lake area of 300,000㎡, and the artificial water that supplies fresh water of 14 million tons in Incheon Songdo International City. The lake is planned, and artificial lakes are planned to be installed in the new town.

In addition, the construction of golf courses used by the Korean people is increasing every year, and the water of ponds installed in artificial lakes or golf courses forms a pond without flow. As such, sludge exists in a stagnant lake or pond. At the outset, water pollution increases rapidly, so it must be collected and removed on a regular basis.

In general, when 3 to 5% of sludge is present in a lake or pond, water is contaminated and dirty. Also, waste sediment mixed with organic and inorganic substances causes water to increase rapidly, and even organisms can survive. It will be impossible to collect and should be collected and removed on a regular basis.

Since domestic dumping is prohibited in 2010, if sludge, which is a large amount of liquid sludge, is not properly handled on land, it will adversely affect the watershed ecosystem or the coastal ecosystem. Thorough sediment management is required from the source.

In general, small ponds such as artificial lakes and golf courses are not equipped with a separate water treatment purification device, but are mostly devices that simply spout water like a fountain and aeration, and because the water is low, the water quality is not seriously polluted and naturally. It was common to purify, but in the case of water-blocked ponds in earnest by treating the bottom of the lake or pond in earnest, eutrophication is fast and when there is heavy rainfall in the rainy season, organic matter or fertilizer flows down to the lake or pond, which can cause water pollution. It causes a sharp increase.

Looking for prior art to remove sludge deposits on the bottom of the underwater, Applicant Patent No. 378,981 "Sludge collection device" of the applicant is disclosed to wipe the sludge and moss by brushing the underwater bottom surface and roll the gravel of the bottom surface Underwater sludge removal apparatus for wiping off moss stuck to gravel while removing the sludge is disclosed. Also, in Patent No. 451031, "Method for removing sludge accumulation in water and apparatus therefor", Accordingly, there is disclosed an apparatus for removing sludge through a brush and a suction device while allowing free rotational movement.

However, the sludge removing device is to remove only the sludge attached to the bottom of the water contacted by the brush in the end, and is accumulated in a rock gap between the bottom of the water in the position where the brush cannot reach, a recess in the gravel, etc. There was a difficult problem to remove the laminated sludge.

In addition, the apparatus was unsuitable for removing sludge generated in a small pond such as a golf course.

Looking at the prior art disclosed in the water purification method in a small facility, such as a golf course pond, the technique disclosed in Patent No. 10-0624495 is embedded in the water treatment tank and the adsorption unit and sterilization in order to purify the water quality of the golf course pond, By connecting the pumps in parallel, the water in the pond is dispersed and processed in a number of water treatment tanks, so that the water quality of the pond is quickly purified and the purified water is supplied to the fountain and aberration so that the water quality purification device of the golf course pond can utilize the landscape effect. Is disclosed.

However, under the condition that several small ponds are distributed in one golf course, the technical concept of installing a plurality of water treatment tanks with adsorption and sterilization units in each pond and connecting them to a pump allows the pond water to be dispersed. It may be possible, but it is difficult to apply in reality.

However, if the preliminary purified water contains different sludge layers, the preliminary water is passed through the fine net separation means and the preliminary water is sent to the settling tank. The invention is completed by confirming that the object of the present application can be achieved by the technical idea to be applied to the process of recycling to the pond.

Therefore, the present application is a sludge removal / separation device, the sludge adsorption unit is provided in a configuration including a high pressure air spray nozzle and a cylindrical brush, the high pressure air spray nozzle is installed in a structure in which the high pressure air is injected directly under the bottom surface of the cylindrical brush; Cylindrical brush is provided as a rotating brush structure to form an oblique inclination angle rather than a straight structure to the surface to provide a structure to sweep the sludge layer to the center portion, the sludge separation device has a vacuum suction hole at the top, a thick network separating means in the middle Disclosed is a sludge adsorption / separation apparatus provided with a configuration in which the preliminary purified water is discharged through a discharge pipe after separating the fine net separation means and foreign substances into and below.
