The waste water purification system is provided with a preliminary tank installed to control the amount of wastewater introduced into the purified water and a purified water channel formed by a waterway frame having a filter water composed of sand, charcoal, gravel and microorganisms. It is characterized by.

Prefabricated artificial river, wastewater purification system according to the present invention will be described in more detail based on the accompanying preferred embodiment.

1 shows an embodiment of a wastewater purification system according to the present invention.

This system allows the wastewater w, which is drained by the discharge pipe 2 from the wastewater source 1, such as a factory, to be received in the reservoir 10 first.

The reservoir (10) is to have a primary filtration process to precipitate the oxidized precipitate (p) mixed in oh, waste water (hereinafter abbreviated as waste water) (w). The wastewater w, which has undergone the primary filtration in the reservoir 10, is fed to the forced filtration device 20 by the water pump 3, and the wastewater w introduced into the inlet 21 is screen 22. Sludge (s) is filtered in the) and then passed through the filter water 23 to have a secondary filtration process to completely filter the sludge (s) in the waste water.

The filter water 23 is a mixture of sand, charcoal, gravel and microorganisms are used in the wire mesh, and in some cases, only the wire mesh that can filter out sludge may be used.

In addition, the forced filtration device 20 is configured to further increase the filtration efficiency by vibrating the forced filtration device 20 as a vibration motor 24 is employed. Reference numeral 25 is a vibration spring.

Wastewater filtered by the filter water 23 of the forced filtration device 20 is not only sludge filtration but also a purification function, and the purification function of the filter water 23 will be omitted in the following description because it will be described in more detail later. In the case where the wire mesh is employed, it is preferable to filter the sludge, so that the filter water 23 is preferably employed.

Wastewater drained from the outlet 26 of the forced filtration device 20 to have a secondary filtration process of the wastewater may be immediately discharged to the purified water passage 40 to be purified,

As shown in the embodiment of FIG. 2, the wastewater may be first discharged to the filtration preliminary tank 30, and then the wastewater may be supplied to the purification water passage 40.

That is, FIG. 2 shows another embodiment of the present invention, and instead of the reservoir 10, the reservoir tank 100 may be installed, and in this case, the wastewater w by the overflow method. Is to be supplied to the forced filtration device 20, the waste water (w) having a secondary filtration process in the forced filtration device 20 is to be drained to the filter preliminary tank (30).

The filtration preliminary tank 30 is provided to maximize the purification efficiency in purifying the wastewater treated by the forced filtration device 20 to the purification water channel (40).

In more detail, the supply amount of the waste water (w) of the preliminary filtration tank (30) by the supply pump (3 ') is supplied to the purified water passage 40, wherein the waste water (w) is purified water passage (40) It is a filtration preliminary tank 30 for maximizing the purification efficiency of the purification water passage 40 by supplying by limiting the amount of surface water flowing to the surface of the filter water 50.

As a result, since the filtration preliminary tank 30 is employed to adjust the amount of wastewater (w) supplied to the purification water channel 40, when another device is installed to control the amount of wastewater supply to the purification water channel 40 is installed. In this case, the filtration preliminary tank 30 may be removed.

Reference numeral 40 in FIG. 1 shows a purification channel according to the present invention.

The purification channel 40 is formed in the open air, for example, it can be formed in a ditch or a river, and can artificially create an artificial river to form the purification channel 40.

Therefore, the purified water channel 40 according to the present invention forms the purified water channel 40 in an open state, and thus is exposed to the outside, thereby facilitating spontaneous and environmental supervision.

In addition, the length (L) of the purified water channel 40 is set in consideration of the type of the waste water, the degree of contamination, etc., and the waste water filtered and purified through the purified water channel 40 through the sewage or river (k). It is discharged immediately).

The purification channel 40 is made by a channel frame 41 that is prefabricated and FIGS. 4 to 8 show such purification channel 40.

The waterway frame 41 may also be formed of a concrete structure, but is preferably made of plastic in consideration of the convenience of handling.

Referring to FIG. 6, the channel frame 41 forms a partition wall 44 having a plurality of holes 43 on both sides of the channel groove 42, and the temperature control tube 45 is inserted into the partition wall 44. It is to have a tube groove 46, the tube groove 46 is to be blocked by the groove plate 44 '.

Here, reference numeral 44a denotes a guide groove into which the groove plate 44 'is fitted.

In addition, the coupling jaw portion 47 and the coupling groove portion 48 into which the coupling jaw portion 47 can be fitted are formed at both sides of the channel frame 41.

Therefore, the water channel frame 41 according to the present invention has a number corresponding to the length L of the purification channel 40 to be formed and is assembled in a prefabricated manner to form one purification channel 40.

In detail, one channel frame 41 to be buried in the ground 60,

The upper part of the waterway frame 41 is buried to be opened, and then another waterway frame 41 is installed so as to be connected to this. At this time, the waterway frame 41 to be connected to the first waterway frame 41 and the coupling groove 48 is formed. The coupling jaw portion (47) of the fitting is to be formed by assembling the entire purification water passage 40 in a way to connect.

Next, the temperature adjusting pipe 45 is installed into the guide groove 44a of the partition 44 to assemble the groove partition 44 '.

Therefore, the temperature control pipe 45 is installed in a state of being inserted into the waterway groove 42 of the purification water channel 40, the hot water or cooling water is circulated to the temperature control pipe (45).

The hot water and cooling water supply unit for circulating the hot water or cooling water flowing to the temperature control pipe 45 is a well-known technology, and thus detailed drawings and description thereof will be omitted.

The filter water 50 is filled in the channel groove 42 of the purification channel 40, and the filter water 50 has a gravel layer 51, a char layer 52, and a sand layer 53 formed from the top thereof. It is composed of microorganisms.

Gravel layer 51 constituting the filter water 50 is formed to form a layer of about 40-42% of the total volume, the char layer 52 30-35%, the sand layer 53 is about 30-25%, The amount is about 10% of the total volume.

In order to allow the wastewater to flow, the filter water 50 has an inclination angle α in the lower direction as shown in FIG. 8, so that sliding occurs downward, but the water channel frame 41 itself is partition wall 44. ), There is no slip or drop in the downward direction.

Therefore, the waste water w flows through the purification water passage 40, and the function of the waste water is to be purified by the filter water 50 during the flow of the waste water.

That is, the sand layer 53 of the filter water 50 is excellent in immersion rate, suitable for the inclusion of nutrients necessary for microorganisms and plants, and is not sensitive to oxidation and contamination. And the charcoal layer 52 is charcoal made of palm fruit, it is excellent in immersion, filtration and water ability, not sensitive to oxidation and pollution, and excellent humidity control ability to control temperature, humidity suitable for the growth of microorganisms Do this.

In addition, the gravel layer 51 is suitable for forming the filter water 50 because the immersion rate is excellent and the characteristics are not sensitive to oxidation and contamination.

Therefore, the wastewater discharged to the purification water passage 40 is not only filtered by flowing naturally by the components of the filter water 50, but also by the microorganisms or plants having strong viability, such as plants and plants that grow naturally according to sunlight and ecosystem principles. It keeps the purification power of (50) continuously.

In particular, it is known that aerobic microorganisms are produced by the principles of the ecosystem when plants or plants are rooted in the filter water 50. By this principle, the purifying power can be maintained as the microorganisms continue to generate and grow. .

Charcoal layer 42 is because the charcoal made of coconut shell is used as this charcoal acts as a function of activated charcoal and deodorizing function, in which zeolite, calcined rock, soda glass, vermiculite, perlite ) Or a mixture of species, etc., will have a better cleansing power. Various additives mixed in the charcoal layer are known ones, and thus description of their components and material properties will be omitted.

In addition, the filter water 50 is a natural oxygen supply during the passage of the waste water between the constituent particles. This is possible because the channel groove 42 formed by the channel frame 42 is exposed to the atmosphere, so that the aeration into the filter water 50 is made, and the purification channel 40 is formed to a considerable length. This is because enough oxygen can dissolve while the wastewater flows through it.

On the other hand, since the purification function for decomposing harmful components in the waste water by the microorganisms in the filter water 50 is a known fact, a detailed description thereof will be omitted, and the characteristic of the present invention is that in the filter water 50 The purification function of the microorganisms is to be long-lasting and the long purification water path 40 is to be purified by the natural state principle in the course of the waste water flowing for a long time.

Therefore, it is necessary to maintain the temperature of the filter water so that the most ideal temperature for the microorganisms in the filter water 50 to inhabit.

Temperature maintenance of the filter water 50 allows the temperature to be maintained for the microorganism by circulating the cooling water to the temperature control pipe 45 in the summer season when the atmospheric temperature is high, while the hot water to the temperature control pipe 45 in the winter season The temperature can be maintained by circulating the temperature. At this time, if you keep warm while covering the plastic, etc. over the purified water passage 40 in winter, it can promote a more desirable temperature maintenance.

In addition, since the purification channel 40 according to the present invention has a long channel, more filtering and purification functions are performed in the upper purification channel into which wastewater w is introduced from the filtration preliminary tank 30, thereby contaminating the portion. The degree is higher than the one below. Therefore, the upper purification water passage 40 is preferably to be replaced regularly, the lower the replacement time is to replace the wider catch.

The replacement of the purified water at this replacement time is facilitated by partial replacement of the waterway frame 41 since the purification waterway 40 is formed by the waterway frame 41. At this time, since the temperature control pipe 45 is connected to the connector 45a at regular intervals in the middle, when the filter water of the connector part on both sides of the section to be replaced is lifted and the connector is disassembled, the temperature control tube of the replacement section is separated. The channel frame of this part can be lifted up with the filter water and replaced with a new one.

In addition, since the purification amount by the purification channel 40 is proportional to the volume of the filter water 50 in the channel, the purification treatment capacity may be adjusted by the width, length, and thickness of the filter material.

On the other hand, the size of each facility according to the present invention is determined according to the amount of wastewater treatment, it is preferable to discharge the wastewater at that time immediately so as not to overload the facility.

In addition, it is possible to adjust the distance (L) to the type of microorganism and the purified water according to the capacity and the water quality of the waste water, the distance (L) can be adjusted by the method of rotating repeatedly as shown in FIG.

In the case where the installation place of the wastewater purification system according to the present invention is limited, as shown in FIG. 9, a small artificial acid (H) is installed as shown in FIG. It is sufficient to make the preliminary filtration tank 30 at a height and to secure the length of the purified water passage 40 sufficient for purification.

The most preferred embodiment of the wastewater purification system according to the invention is shown in FIG.

Here, the wastewater (w) discharged through the discharge pipe (2) from the wastewater source (1) is directly introduced into the forced filtration device (20), and then the supply pump (3 ') in the reservoir (10) or preliminary filtration tank (30). While supplying to the purified water channel 40 formed in the artificial acid (H ') through the) while forming a spiral to the purified water channel 40 of the artificial acid (H') to form a long purified water channel (40) To form more complete wastewater purification.

The effect obtained by the present invention is that wastewater treatment is performed by the purification action close to nature, so that the installation and maintenance is easy and the optimum purification effect can be obtained at the lowest cost.

In particular, since the wastewater purification facility is open to the open air, it is easy to check and monitor untreated wastewater discharge, which provides easy environmental supervision, thereby promoting voluntary wastewater treatment, thereby greatly preventing water quality and environmental pollution. It will provide a useful wastewater purification system that will contribute.
