The present invention relates to a water purification device for multiple generations, and more particularly, to a water purification device that can be used simultaneously by multiple generations by purifying a large amount of tap water and ground water using a heavy metal adsorption step of zeolite and an organic material adsorption step of activated carbon.

In general, tap water sterilized by chlorine is introduced from a water purification plant in a storage tank installed in the basement of a building to supply tap water to a high-rise building or an apartment house. The water in the storage tank is pumped into a water supply tank installed on the roof of a building. It is pumped and then fed to the water of each household through the pipeline. Water in the reservoir tank is often contaminated by various germs during use period, there is a hygiene problem to use as drinking water as it is. In addition, in recent years, various heavy metals, organic substances, etc. from raw water are introduced, causing many social problems. In addition, chlorine is effective in sterilizing various bacteria contained in the low water in the water tank, but when the chlorine is combined with organic matter, trihalomethane (THM) is produced, which is carcinogenic. Since it is an inducing substance, the necessity of purifying tap water before using it as drinking water is increasing recently.

As such, the contaminated tap water may be adsorbed and removed by zeolite, but the zeolite may not absorb organic materials. In addition, by passing the contaminated water in granular or lumped activated carbon, the pollutant can be adsorbed and removed by activated carbon, but there is a problem that heavy metal remains and bacteria grow in the activated carbon.

In addition, the adsorbing power of the zeolite or activated carbon decreases as the adsorption capacity approaches the saturation state, and after that, the zeolite or activated carbon does not function as a treatment agent.

As described above, zeolite and activated carbon, which have had a reduced adsorption performance, have to be regenerated and activated to remove the adsorbed material.

The present invention has been made in view of the above circumstances, and provides a multi-generation water purification device capable of sterilizing with a final sterilizer after removing heavy metals, ammonia and organic substances from tap water while passing through a two-stage zeolite tank and an activated carbon tank. The purpose is to.

The multi-generation water purification device of the present invention is a safe drinking water for the tap water supplied to the first filtration stage of the filtration tank, the adsorption of heavy metals and ammonia in the zeolite tank, the adsorption of organic substances in the activated carbon tank and the sterilization of microorganisms in the UV sterilizer or ozone generator. Is an integer.

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

1 and 2 shows a multi-generation water purification device of the present invention, in which the tap water is introduced into the filtration tank 1 by a pump in a water storage tank.

Tap water flowing into the filtration tank is filtered through P.P.

Tap water from which suspended substances are removed is introduced into the zeolite tank (2) through a connected pipe to absorb and remove heavy metals and ammonia.

In the heavy metal adsorption step of the zeolite tank 2-4 shown in FIG. 1, hard water is softened and the ammonia removal capacity is fast and safe treatment is possible without being affected by concentration and water temperature fluctuations. In addition, the radioactive isotope cesium (Cs) is removed and heavy metal ions are removed by adsorption. The zeolite tank (2-4) is passed through the primary tank (2) and the secondary tank (3) through the opening and closing of the pipe and the valve of the corresponding path, and also installed a tertiary tank (4) as a spare zeolite adsorption capacity When deteriorated, recycle and use it. That is, when the primary zeolite tank (2) and the secondary zeolite tank (3) are used, the tertiary zeolite tank (4) is reserved, and after the long term use, the tertiary zeolite tank (4) and the secondary zeolite tank (3) are replaced. The primary zeolite tank (2) is regenerated and standby in reserve.

Regeneration of the zeolite in the zeolite tank (2-4) is a pump to introduce sodium chloride or calcium chloride into the regeneration passage (A) and to pass through the zeolite tank (2-4) to replace the sodium or calcium ions and the adsorbed heavy metal ions to circulate Play it and use it.

In FIG. 2, other zeolite tanks 2, 3, 3, 8, and 9 may be used instead of the zeolite tanks 2-4.

As described above, the water absorbed by the heavy metal and the ammonia is introduced into the activated carbon tank 5 through the pipe and the valve of the opening and closing to remove various organic matters. The activated carbon of the activated carbon tank 5 adsorbs and removes various organic substances, carcinogenic substances such as THM, phenols and anionic surfactants.

When the adsorption capacity of the activated carbon approaches saturation, the activated carbon tank 6 is used as a spare for regeneration regeneration treatment to remove the adsorbed material.

Tap water from which various harmful substances such as heavy metals, ammonia and organic substances are removed through the zeolite tanks 2 and 3 and the activated carbon tank 5 as described above is sterilized through an ultraviolet sterilizer or an ozone generator 7 to be suitable as drinking water. The water supply makes it possible to use it in several generations of tap water.

The multi-generation water purification device of the present invention will be described with reference to the accompanying drawings.

In FIG. 1, tap water is introduced into the filtration tank 1 through a pump from a water storage tank, filtered, and then introduced into the primary zeolite tank 2 through a corresponding pipe and an opening / closing valve, and in this zeolite tank 2 Tap water is first passed through the zeolite and then flows into the secondary zeolite tank 3 again to undergo secondary zeolite treatment. Here, the tertiary zeolite 4 is kept as a standby.

The water flowing out of the zeolite tanks 2 and 3 flows into the activated carbon tank 5 through the corresponding pipe and the opening / closing valve and flows out through the activated carbon. Here again, the other activated carbon tank 6 is provided as a spare. Water passing through the activated carbon of the activated carbon tank 5 is supplied as drinking water through the ultraviolet sterilizer or ozone generator 7 as described above.

Meanwhile, in FIG. 1, tap water passing through the filtration tank 1 from the water storage tank first flows into the activated carbon tank 5 through the corresponding pipe and the valve of the opening and closing, passes through the activated carbon, and then the primary zeolite tank 2, The secondary zeolite tank 3 may be introduced, passed through the zeolite, passed through an ultraviolet sterilizer, or passed through the ozone generator 7 to be supplied as drinking water.

In FIG. 2, water flows from the reservoir tank to the filtration tank 1, is filtered, and then flows into the primary zeolite tank 2 through the pipe and the valve of the opening and closing, and the tap water is zeolite in the zeolite tank 2 After the first pass through the activated carbon tank (5) is passed through the activated carbon and outflow. As described above, the water passing through the activated carbon of the activated carbon tank 5 flows into the third zeolite tank 8. The secondary zeolite tank 3, the activated carbon tank 5, and the quaternary zeolite tank 9 are provided as spares.

Water passing through the third zeolite tank 8 secondly is supplied to drinking water through an ultraviolet sterilizer or an ozone generator 7.

On the other hand, in FIG. 2, tap water flows into the filtration tank 1 from the water storage tank, is filtered, and then flows into the fourth zeolite tank 9 through the pipe and the valve of the opening and closing, and the tap water from the zeolite tank 9 After passing through the zeolite first and then into the activated carbon tank (6) is passed out through the activated carbon. At this time, the tertiary zeolite tank 8 and the activated carbon tank 5 are reserved.
