The present invention may, however, be embodied in many different forms and should not be construed as limited to the embodiments set forth herein. In order to clearly explain the present invention, parts not related to the description are omitted, and similar parts are denoted by similar reference numerals throughout the specification.

2 is a plan view of Fig. 1, Fig. 3 is a sectional view taken along line AA of Fig. 1, Fig. 4 is a sectional view taken along line BB of Fig. 1, and Fig. , And Fig. 5 is a cross-sectional view taken along line CC of Fig.

1 to 5, a mine drainage and water treatment apparatus 100 using an integrated drinking water greening greenhouse according to a preferred embodiment of the present invention includes an inflow path 110, a flow path 120, a filter medium 130 ), A watercolor green paper 140, and a discharge passage 150.

The inflow path 110 is for introducing mine drainage and is formed at the front end of the flow path 120.

One end of the channel 120 is connected to the inflow channel 110 for passing the mine drainage introduced through the inflow channel 110. In this case, a flow rate control tank 160 may be formed between the inflow path 110 and the flow path 120, which will be described in detail later.

In the meantime, the present invention is characterized in that the flow path 120 is formed in a zigzag shape. In other words, by constructing the channel 120 repeatedly opened at one side and the other side, it is possible to construct the longest channel at a certain area to prolong the residence time of the mine drainage, thereby maximizing the water purification efficiency and, at the same time, So that it can be easily installed.

Accordingly, the mine drainage is transported while reciprocating between the one side and the other side of the channel 120. In this process, the filtering agent 130 and the water-soluble greenery paper 140 are purified for a long time by the combined action, . In addition, due to the dense structure of the flow path 120, it is possible to easily install the apparatus in a canyon, a valley, a narrow place, a small-sized marshland, etc., thereby reducing the cost of securing the site.

The filter medium 130 is filled in the channel 120 to purify mine drainage. The filter medium 130 is preferably made of an asymmetric medium having a smooth and porous structure. For example, the natural complex mineral such as anion complex mineral, limestone, and natural natural material can be selectively applied according to the water quality. The environmentally friendly energy of the selectively applied porous medium provides anion to mine drainage and various polluted influent water, and purifies pollutants by oxygen activation, oxidation, neutralization, coagulation sedimentation and solidification. The pollutants are also removed by the microorganism's natural activity and microorganism's natural activity and circulation osmotic pressure evapotranspiration to the surface soil by the pores of the natural complex mineral medium mentioned above, Thereby providing a hydroponic vegetation environment.

The hydroponic green zone 140 is formed on the channel 120 as a means for spontaneously purifying the mine drainage together with the filter medium 130 by a plant. In this case, the soil layer of the hydroponic green zone 140 may be composed of the active soil layer 141, the organic material layer 142, the high quality soil layer 143, and the planting soil layer 144, which are sequentially stacked as shown in FIG. Compost, rice straw, litter, etc. may be used as the organic material 142.

On the other hand, a large plant such as a tree or a shrub is planted in the soil layer. In general, large sized landscaped plants can selectively absorb and remove organic matter, heavy metals and other water pollutants selectively, and can selectively purify water by selectively planting species suitable for the origin of water pollution. According to the present invention, there is an advantage that effective and reasonable water treatment can be performed through the composition of the hydroponic vegetation environment.

As described above, when the plant is planted in the soil layer, natural energy dissipation and absorption can be achieved through photosynthesis of the plant and the like, thereby enabling highly efficient natural purification water treatment in an environmentally friendly manner. In particular, It is possible not only to prevent direct and indirect environmental destruction and landscaping of surrounding environment due to facilities and alpine landscaping, but also to restore the environment because the corresponding areas are green parks.

The discharge passage 150 is formed at a rear end of the oil passage 120 for discharging purified water.

The basic constitution of the present invention has been described above. In addition to the above-described structure, the present invention may be additionally provided with other structures for purifying the mine drainage more effectively.

First, a flow rate regulating tank 160 may be formed at a front end of the flow path 120. The flow rate control vessel 160 is formed between the inlet passage 110 and the flow passage 120 and includes a gravity pressure acting partition wall 161 and a flow rate control partition wall 162.

The gravitational pressure acting partition wall 161 is provided to naturally transfer the mine drainage introduced through the inflow channel 110 to the aeration tank 164 by the gravitational pressure, do. In this case, the gravitational pressure acting partition wall 161 is spaced apart from the bottom of the flow rate control vessel 160 by a predetermined height so that the mine drainage can pass through.

The flow rate adjusting partition wall 162 is provided at the rear of the gravity pressure acting partition wall 161 to control the storage flow rate of the mine drainage. In this case, the flow rate adjusting partition wall 162 is installed in an open form as opposed to the gravity pressure acting partition wall 161, and thereby the mine drainage introduced into the lower portion of the gravity pressure acting partition wall 161 rises And may be dropped from the top of the flow rate adjusting partition wall 162. Accordingly, since the mine drainage is naturally aerated by the natural fall while passing through the flow rate regulating partition wall 162, the oxidizing action is promoted in the aeration tank 164 and the primary neutralization is performed.

In this case, a drain pipe 163 may be installed at one side of the flow rate control vessel 160. As shown in FIG. 1, the drain pipe 163 is provided to be bent downward at the upper end of the front side of the flow rate control vessel 160, as shown in FIG. 1 for overflowing the incoming mine drainage. Accordingly, when the mine drainage flows into the flow rate control vessel 160 at a predetermined amount or more when the flow rate is high, the flow rate of the flow channel 120 can be controlled by being discharged to the outside of the purification zone through the drainage pipe 163.

Meanwhile, a flow rate maintaining tank 170 may be formed at a rear end of the flow path 120. Specifically, the flow rate control tank 170 is formed between the flow path 120 and the discharge path 150, and includes a gravity pressure acting partition wall 171 and a flow rate storage barrier rib 172.

The gravitational pressure acting partition wall 171 is provided at the inner upper end of the flow rate control tank 170 for naturally conveying the purified water discharged through the flow path 120 by gravity pressure. In this case, the gravitational pressure acting partition wall 171 is spaced apart from the bottom of the flow rate control tank 170 by a predetermined height so that the purified water can pass through the bottom.

The flow rate storage barrier rib 172 is provided to store a predetermined amount of purified water and is spaced apart from the rear of the gravity pressure barrier rib 171. In this case, the flow rate storage partition wall 172 is installed in an open form as opposed to the gravity pressure acting partition wall 171, so that the purified water flowing into the lower portion of the gravity pressure acting partition wall 171 rises, And may be dropped from the top of the flow storage reservoir 172. Therefore, the purified water having the pollutant removed through the passage 120 is naturally ventilated by the drop before finally discharging, so that the purification efficiency can be further improved.

On the other hand, a certain amount of the purified water can be stored by the flow rate storage partition 172 in the dry season when the flow rate is low. That is, when there is no flow storage barrier rib 172, the purified water passing through the lower portion of the gravity pressure barrier rib 171 is directly discharged. However, if the flow storage barrier rib 172 is present, The purge can be continuously performed in the flow path 120. Accordingly, the mine drainage in the flow channel 120 is accumulated and stagnated by a certain amount during the dry season, so that purification can be performed irrespective of the amount of mine drainage.

As described above, in the present invention, the flow path 120 is integrated with the flow rate control tank 160 and the flow rate control tank 170 to control the water flow in the flow path, By increasing the amount of dissolved oxygen, the mine drainage can be accumulated for a long time in the active water state, so that effective purification efficiency and important hydroponic vegetation environment can be obtained.

In this case, a water-permeable partition 180 (181) of a wire mesh structure is installed between the flow control counterpart 160 and the flow passage 120, and between the flow passage 120 and the flow- . The water permeable partition 180 or 181 serves to prevent the medium of the filter medium 130 from flowing into the flow rate control tank 160 and the flow rate control tank 170.

As shown in FIG. 5, lids 190 and 191 may be installed at the upper portion of one side of the flow rate control tank 160 and the flow rate control tank 170, The quality of the water at the time of discharge and final discharge can be visually confirmed.

The construction of the mine drainage water treatment system using the integrated drinking water greenhouse according to the preferred embodiment of the present invention has been described above. Hereinafter, the operation of the mine drainage water treatment system using the integrated greenhouse water greenery greenhouse according to the preferred embodiment of the present invention will be described.

First, the mine drainage flows into the flow rate control vessel 160 through the inflow channel 110. In this case, when the amount of the mine drainage water exceeds the capacity of the flow rate control vessel 160, the water is discharged to the outside of the purification zone through the drainage pipe 163 to adjust the flow rate.

Thereafter, the mine drainage is transferred to the rear of the flow rate control vessel 160 by the gravitational pressure and flows into the lower portion of the gravitational pressure acting partition wall 161. The mine drainage thus flowed does not flow immediately but is shut off by the flow rate adjusting partition wall 162 and then falls to the rear aeration tank 164 from the upper end of the flow rate adjustment partition wall 162. As a result, there is a drop in height of the flow rate adjusting partition wall 162 and natural aeration is performed. In this process, neutralization is primarily performed by the oxidizing action.

Subsequently, the natural abandoned mine drainage flows into the flow channel 120 through the water flow type partition 180, and is transferred to the rear end while being repeatedly circulated to one side and the other side of the flow channel 120. In this case, the mine drainage is purified through the complex action of the filter medium 130 and the water-soluble greenery paper 140 through the channel 120. Specifically, the anion is provided to the mine drainage due to the eco-friendly energy of the anion complex mineral, limestone, and natural natural material constituting the filter material 130, and the pollutant is oxidized, oxidized, neutralized, coagulated, At the same time, water treatment is carried out through microbial engraftment, proliferation and circulation according to the pore activity of the natural complex mineral medium. In addition, since the planting of various trees such as trees, shrubs and the like planted in the water greenery green pines 140 and the stable vegetation environment are provided, high-efficiency self-purification of the plants is performed, thereby securing stability of water purification for a long period of time.

The purified water from which contaminants have been removed through the above-described process is finally introduced into the flow-rate maintaining tank 170 through the water-permeable partition 181. The purified water flows into the lower portion of the gravity pressure acting partition wall 171 and rises after riding on the flow rate storage partition wall 172 and falls backward. In this process, natural aeration is performed to obtain additional neutralization effect. In this case, since the purified water is not drained by the flow rate storage partition 172, the purified water is continuously stored in the water storage greenhouse 140 due to the complex action of the filter medium 130 and the greenhouse 140.

On the other hand, the purified water discharged from the flow-rate maintaining tank 170 is discharged to the purification zone, the marshland or the river through the discharge port 150.

The preferred embodiments of the present invention have been described in detail with reference to the drawings. It will be understood by those of ordinary skill in the art that various changes in form and details may be made therein without departing from the spirit and scope of the present invention as defined by the appended claims.
