Description

River Purification Method Using Water Plants {WATER TREATMENT METHOD WITH PLANT}

The present invention relates to a stream purification system using purified plants for improving the water quality of streams or lakes contaminated by industrial wastes, wastewater or domestic sewage, and more specifically, the removal of the causative agents of eutrophication and low concentration of organic pollutants. The present invention relates to a river purification system using purified water plants installed in exclusion sites (ditches) or inner ponds of rivers, which can treat the treatment more effectively.

In general, river purification is a method of purifying water quality through sedimentation, adsorption, and digestion of microorganisms by passing river water, sewage, etc. in a contact oxidation tank filled with gravel, crushed stone, or various media. It is used for sewage treatment at low concentrations (below 80 mg / l BOD).

However, these water purification devices need to build large concrete structures to purify the rivers, and in case of rainy season or heavy rainfall in summer, there is a problem of being buried or soiled by soil leakage, and nitrogen and phosphorus, which are the cause of eutrophication, are not removed. There was a problem.

Therefore, an object of the present invention is to devise to overcome the above-mentioned conventional problems, it is not necessary to create a large-scale concrete construction separately, when the rainy season during the summer or a lot of precipitation is buried by soil leakage or blockage substrate. The subsurface flow SF of artificial wetland is used to prevent the removal of organic pollutants and the causes of eutrophication. The facility and maintenance costs are low, and the buffering capacity and nature-friendly environment can be applied to various environments. To provide a river purification system using water plants.

An example of a river purification system using purified water according to the present invention for achieving the above object is a primary sump for collecting river water, and a secondary sump for storing river water from which the contaminants are removed from the primary sump; A sedimentation tank connected to the secondary sump and settling the sediment contained in the river water, an equalization tank for distributing the contaminated river water that has passed through the sedimentation tank to the inlet pipe, a plurality of distribution pipes diverging from the inlet pipe and the inlet pipe, Characterized in that the purification paper including a collecting pipe and the drain pipe for collecting the purified purified water.

The clarifier has a plurality of distribution pipes and a plurality of collecting pipes are alternately disposed between the gravel layer, drain pipes connected to the collecting pipes are installed at both sides, and a discharge tank is installed at the end of the drain pipe to discharge the amount of purified water discharged. It is characterized by being able to adjust the water level by adjusting.

The distribution pipe, the collection pipe and the drain pipe is characterized in that the perforated pipe.

The distribution pipe is characterized in that it is disposed higher than the collection pipe.

The gravel layer is formed where the distribution pipe and the collection pipe is installed, the gravel layer and the sand layer are alternately arranged, the clay layer is laminated on the sand layer, characterized in that the plant is planted, such as reeds.

In order to prevent contamination of the ground layer is characterized in that the waterproof sheet covers the ground layer.

Hereinafter, the present invention will be described in detail with reference to the accompanying drawings.

Referring to Figure 1, the stream purification system 1 using the purified water according to the present invention is installed in the exclusion pond (5) or jejiji adjacent to the river (3), the primary water tank (7) for collecting the river water And, the secondary water tank (9) for storing the river water from which the contaminants have been removed from the primary water tank (7), and the sedimentation tank (11) connected to the secondary water tank (9) for sedimentation, etc. contained in the river water And, the equalization tank 13 for distributing the sewage through the sedimentation tank 11 to the inlet pipe 15, and the plurality of distribution pipes 17 which are separated from the inlet pipe 15, the inlet pipe 15, It consists of the purification paper 31 containing the collection pipe 19 and the drain pipe 21 which collect the purified purification water.

Referring to FIG. 2, in the clarifier 31, distribution pipes 17a, 17b, and 17c and collection pipes 19a, 19b, 19c, and 19d are alternately disposed between the sand layers 33. The purified water discharged by the discharge pipes 21a and 21b connected to 19a, 19b, 19c, and 19d is provided in a side with a predetermined clearance, and the discharge tanks 23a and 23b are installed in the end of the said discharge pipes 21a and 21b. The water level can be controlled by adjusting the discharge amount of
