Description

Simple water supply altitude water purification system {ADVANCED WATER TREATMENT SYSTEM FOR PROVISIONAL WATERWORKS}

The present invention relates to an advanced water purification system of a simple water supply or small-scale water supply facilities, and more specifically, a primary filtration tank for filtration and removal of various contaminants in influent water flowing from a water intake source, and the first filtered filtration water. By treating the water with clean water, the drinking water is finally provided to the residents of farming and fishing villages for a healthy and healthy life.

At present, domestic simple water purification facilities or small water supply facilities are exposed to various pollutants, so advanced water treatment is essential, but there are many sources of water intake in valley water, natural water, ground water, reservoirs, etc. It is difficult to install or use large-scale water treatment plants such as municipal units.

In particular, the installation of water pipes is essential for supplying clean tap water from a wide-area water purification plant to small villages scattered sporadically, but there are many difficulties such as passing through mountains and mountains. There is a need for a village water supply system that is easy to manage and inexpensive.

As for Table 1 and Table 2, the water supply rates in 2001 and Korea are high at 98.4% and 96.5%, respectively, while the county area is only 29.0%. It can be seen that there is.

As shown in Table 1 and Table 2, in rural and fishing areas such as towns and villages, the water supply rate is very poor, and even the water supply is unsanitary, so it is not safe to use as drinking water.

In some specific areas, drinking water is treated as purified water, but almost all areas are drinking water after the minimum chlorine disinfection process, and in valleys, valley water is used as it is. In the case of E. coli sterilization degree is used as drinking water.

In addition, in the case of using valley water as drinking water, foreign substances such as sand, moss and even insects are mixed in drinking water, and when using ground water or natural water, filtration or purification is not performed at all. Verification is difficult. Efforts are being made to purify raw water from various intake sources such as valley water, groundwater, and natural water, but it is very poor in each household by purifying water using charcoal, sand, and gravel in a conventional manner.

In addition, various simple water purification facilities have been developed, but the installation cost is high, and the method of expanding the household water purifier or the method of reducing the large-scale water treatment facility is not practically inexpensive to farming and fishing villages, and there are many problems in management.

On the other hand, in case of small water supply facilities, it is very difficult to guarantee safe drinking water from pollutant sources. In particular, if the intake source is located near paddy fields, fields, orchards, and rivers, refer to "Research Results of the Ministry of Environment's Groundwater Monitoring Network (2003)." In the case of TCE (trichloroethylene), PCE (tetrachloroethylene), NO ₃ , Cl, pH in order to exceed the water quality standards. In the region of pollution concern, the major pollutants were TCE, NO ₃ -N and PCE. In general, NO ₃ -N and E. coli showed high excess rates.

Therefore, the purpose of the present invention is to provide more sanitary and stable drinking water to the residents of farming and fishing villages using simple water supply and small water supply facilities.

The present invention is to filter the contaminants in the influent, such as groundwater, natural water, valley water, storage water from the intake, the intake source to supply clear and clean water that has been treated and purified such contaminants. Moss, sand, soil, rice, leaves, insects, pests, etc. are first filtered and treated by adsorption of a secondary advanced water purification system composed of a three-stage filtration tank, activated carbon, etc., and ultraviolet (U / V) or It is sterilized with ozone (O ₃ ) so that drinking water can be supplied from farms and fishing villages.

The primary filtration tank is made of filtration and sedimentation without power, and the light and fine particles are attached to the filter network to filter out, and the heavy particles sink to the bottom. In addition, when the filter network is too dense when passing through the primary filter tank, the filter network cannot withstand the pump pressure, so that the primary filter purpose can be faithfully achieved while enduring the pump pressure sufficiently.

Therefore, the present invention is filtered while passing the water from the intake source through the primary filtration tank, nitrate nitrogen, ammonia nitrogen, TCE (trichloroethylene), PCE (tetrachloroethylene), Cl, pH that causes bacterial heterogeneity By adsorbing the hardness, lime powder and heavy metals, it is possible to supply clean and sanitary drinking water that is completely purified.

In describing the present invention, the same elements in the drawings are denoted by the same reference numerals as much as possible, and detailed descriptions of related known configurations or functions will be omitted so as not to obscure the subject matter of the present invention. Hereinafter, described in detail with reference to the accompanying drawings a preferred embodiment of the present invention.

The present invention installs the primary filtration tank at the inlet of the intake source without additional building structure, and installs the secondary advanced water treatment system at the rear end of the primary filtration tank so that the inflow water is highly purified. These problems are neatly solved, thus providing clean, purely purified drinking water.

The present invention is to filter the filtered water filtered by the contaminants and the like by the primary filtration tank (2) to the secondary high-altitude water purification system.

Intake water (W1) flowing into the primary treatment tank (2) in the present invention is valley water, natural water, groundwater, reservoir fresh water in the reservoir, rainwater One or more of at least one of these.

The primary filtration tank (2) is made of filtration and sedimentation with no power, light and fine particles are attached to the filter 29 and filtered, and the heavy particles sink to the bottom.

In addition, the primary purified water in the primary treatment tank 2 installed in the filter type filter 29 of 50 l to 100 l treatment scale per minute is usually used in the farm and fishing villages that do not use a pressure pump. In this case, it is preferable that the drinking water is supplied to the inhabitants by non-power by transferring to a storage tank installed at a high position by the pump 1 and then being pressurized by gravity there.

As shown in FIG. 1, the secondary advanced water treatment system includes a water storage tank 4, a pump 6, a three-stage filtration tank 8, an activated carbon filter 10, an ultraviolet (U / V) treatment tank 12, and a pump ( 14) and the like, the ion exchange tank in which the pump 16 and the ion exchange resin are installed between the three stage filtration tank 8 and the activated carbon filter 10 when the hardness of the inflow water W1 is high as shown in FIG. 2. (18) can be additionally configured.

The water storage tank 4 is a kind of flow control tank for adjusting the amount of processing water containing the filtered water from which the contaminants and the like are removed by the primary filtration tank 2, and the three-stage filtration tank 8 is the primary by using three filter cloths The filtered treated water is highly purified. In addition, in the ion exchange tank 18, the inflow water (or treated water) in the hard water state is softened by the built-in ion exchange resin. In addition, the activated carbon filter 10 adsorbs and removes heavy metals in the treated water, and the ultraviolet (U / V) treatment tank 12 irradiates ultraviolet rays (U / V) with the treated water to remove bacteria and pathogens from the purified water. This is sterilized.

Sterilization in the treated water may be achieved by installing an ozone sterilization tank instead of the ultraviolet treatment tank 12. That is, which generates ozone (O ₃₎ in the air, and then a height by supplying ozone (O ₃₎ into the water purification can can be sterilized dissolved (bubbling) bacteria and pathogens and the like in the treatment water in a manner that, mosses It is possible to prevent the breeding and proliferation of the.

Looking at the configuration of the subject innovation treatment tank (2), the water inlet pipe 20 and the water outlet pipe 22 is connected to the upper and lower sides of the cylinder (3), respectively. The cylinder 3 is an elliptical ellipsoid type as shown in FIG. 3 or an ellipsoidal upper and lower part as shown in FIG. 10, which is attributable to the removal of contaminants in the influent. Therefore, since the contaminants in the inflow water is naturally collected and precipitated to the lower portion of the tubular body 3 having an elliptical structure, the floating amount can be greatly reduced, and it can be easily removed to the outside through the discharge port 50 and the discharge pipe 60.

The outlet 50 may be used to remove a large amount of contaminants 40 or a large volume of contaminants or long length of contaminants, the discharge pipe 60 is to remove the small size of the contaminants 40 or the primary treatment tank ( Can be used to clean the inside of 2).

The elliptical structure of the cylinder 3 is described as an example, and of course, it does not need to be limited to the elliptical. For example, it can be formed into a triangular, square, polygonal, spherical or deformed shape thereof, of course, in order to reduce the floating water inlet 28 is to have a structure that the contaminants in the influent (W1) can naturally fall down.

The primary treatment tank 2 is installed such that the filter 26 having the microporous plate 24 formed therein is inclined inside the cylinder 3 supported by the support member 5 as shown in FIGS. 3, 4, and 5.

The contaminants 40 descending along the inclined plates 38 and 40 are collected by dropping into the collection tank 42 positioned below the inclined plates 38 and 40 through the drop hole 44.

The inclined plates 36 and 38 have a slope of 40 ° to 70 ° so that the contaminants 40 such as moss, sand, soil, soil, leaves, insects, pests, etc. can quickly fall into the collection tank 42. By varying the inclination of the two side inclined plates 36, 38, the contaminants 40 in the inflow water W1 naturally fall into the collection tank 42.

The inclined plate 38 which is opposite to the water inlet pipe 20 has a slope of 55 ° to 70 °, so that most of the incoming contaminants 40 fall into the collection tank 42 quickly. , The other inclined plate 36 has an inclination of 40 ° to 55 ° to prevent the rise of the contaminants 40 dropped into the collection tank 42, and some of the contaminants floating in the inlet tank 28 is inclined surface The drop flows into the collection tank 42 naturally.

Since the drop hole 44 is relatively narrow, the rise of the contaminants 40 collected by the collection tank 42 is prevented, and thus the increase in turbidity is prevented. In addition, the turbidity of the influent is prevented by increasing the inclination at the end of the inclined plate 38 having a more inclined position than the end of the other inclined plate 36 having a less inclined.

The lower side of the primary treatment tank (2) is provided with a transparent window 48 to determine the degree of floating of the contaminants (40), the accumulation and deposition amount of the contaminants (40), the primary treatment tank (2) The other side of the lower is provided with a discharge port 50 for discharging the contaminant 40 to the outside of the primary treatment tank 2, and a discharge door 52 for blocking the discharge port (50). The transparent window 48 and the discharge door 52 are maintained by a rigid sealing (sealing) by the respective sealing member (54, 56).
