[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a method for removing dust from rivers and purifying water for purifying river water by removing pollutants such as illegally dumped domestic waste and waste oil.

[0002]

2. Description of the Related Art Conventionally, as a method for removing various kinds of dust flowing in a river, a stone shavings basket for removing dusts, which is a synthetic resin basket filled with a plurality of stones, is arranged in a row in the width direction of the river and then flows down. There is known a method of blocking and removing dust.

[0003]

However, the conventional method using the stone slag for removing dust has the following drawbacks. First, since the dust slag removing basket is relatively small,
It can only be installed in small rivers.

Secondly, since the dust slag removing stake is fixed to the riverbed with concrete, it is necessary to perform a troublesome foundation work and the construction cost is high. In addition, since the quality of water is changed due to the use of concrete, it is not a favorable environment for living things.

Thirdly, since the stone slag for removing dust is fixed to the river, it is difficult to replace it when it becomes dirty.

Fourth, although tangible dust can be removed, chemical contaminants such as small waste and waste oil mixed in river water cannot be removed.

The present invention has been made in view of the above-mentioned drawbacks of the prior art. It is possible to remove a wide range of tangible dust and intangible pollutants in a batch and purify water, and to easily install and replace them. It provides a dust removal and water purification method for rivers.

[0008]

The method of the present invention configured to solve the above-mentioned problems is a stone basket for removing dust, which is formed by storing a plurality of stones in a metal cage, and a metal cage. In addition to arranging an activated carbon filler filled with activated carbon in a microporous container, and located at least on one side of the activated carbon filler, a plurality of buffer stones are filled in the activated carbon basket for water purification, and Using a depressing stone, a plurality of the dust removing stone baskets are arranged in the width direction of the river, and the buffer stone side in the river width direction is adjacent to the downstream side of the dust removing stone basket. A plurality of activated carbon baskets for water purification are arranged in a state of being positioned on the upstream side, and
The energy-reducing stone is disposed in the river at a position downstream of the activated carbon basket for water purification.

[0009]

[Operation] The stone slag for removing dust blocks and retains relatively large dust that flows down in the state of floating in water. The activated carbon basket for water purification blocks small dust that has passed through the stone basket for removing dust and adsorbs contaminants mixed in the water.
The de-energizing stone reduces the flow velocity, and effectively blocks large and small trash with the stone shavings for removing dust and activated carbon for cleaning water and adsorbs pollutants efficiently.
