Description

Compound Water Treatment System {Water Treatment System}

The present invention relates to a complex water treatment system using chlorine (sodium hypochlorite), in particular chlorine is added to the raw water supplied by the pipe (ground) in the apartment complex, factory, feeding center, etc., stored in a water tank and then UV treatment The present invention relates to a complex water treatment system for sterilizing, purifying and draining through an apparatus or the like.

In addition, among the terms used in the present invention, 'raw water' means water supplied by, for example, ground water, 'water' means water in which chlorine is introduced into raw water, and 'purified water' is purified water according to the present invention. Means water that is treated and supplied to the user.

In general, everyone has a basic desire to drink clean water, and humans also want to live longer. The desire to live longer is also reflected in the interest in clean water. Thus, sometimes chlorine-disinfected tap water is washed and cleaned, and drinking water is replaced with mineral water or water.

On the other hand, the demand for purified water is increasing day by day, and as the cause of industrial activities is being advanced, various harmful substances are being introduced into rivers and lakes, which are major water sources, and the importance of water quality management of the water we drink every day increases. It's happening.

In other words, the increase in population and industrialization contaminates water supplies, and the development of analytical technology enables detection of trace amounts of pollutants that could not be detected until now.

As described above, the demand for clean water and the necessity of purified water are increasing day by day, and much research and efforts are being made to develop clean water technology to drink clean drinking water.

On the other hand, the water purification method can be largely classified into three types: reverse osmosis (Ultra Osmosis), hollow fiber (Ultra Fiteration) and water-slurry (π-Water).

In the case of reverse osmosis, pure water molecules pass through the semi-permeable membrane by forcibly applying contaminated water to the contaminated water, and chemicals or foreign substances dissolved in the water are semi-permeable membranes. It refers to a system that purifies water by applying the principle of preventing passage of water.

In the case of Ultra Fiteration, various microorganisms of hollow fiber {0.01 ~ 0.04 micron or less) are removed to remove various bacteria, impurities, and odors in the water. A good mineral ingredient is a precision filtration method that preserves it with water.

The π-water of π-Water is very similar to the water (living water) in our body, and it acts directly on the cells in the body to activate cellular tissues, thereby enhancing natural healing and keeping our bodies healthy. To act as a return.

However, even if the water is purified by applying the water purification method as described above, residual bacteria, odors and organic substances in the purified water are not completely removed. In other words, the existing water purification method has a water purification function that is vulnerable to sterilization.

In addition, the above-described integer method essentially uses a filter. If the filter part is not periodically disinfected, there is a problem that bacteria are generated. In addition, the conventional water purification system has a problem that bacteria are generated by pinching water on the surface of the reservoir.

On the other hand, a technology that adds the sterilization function to the existing water purification method has been developed and implemented, but in the existing water purification method with this sterilization function is a method of water purification and sterilization is made by the method of sterilizing the water passing through the filter. This technique also causes bacteria to develop if the filter is not disinfected periodically.

In addition, an example of a technique for treating the purified water of the source water is disclosed in Japanese Patent Laid-Open No. 2005-0051062 (published on June 1, 2005).

In other words, the above publication instantly dissolves high concentrations of oxygen in sterilized and purified water by photochemical reaction of high functional activated carbon fiber adsorbent and photocatalyst / ultraviolet, stabilizes dissolved oxygen molecules, and degasses oxygen molecules even after opening. In order to minimize the oxygen water is disclosed a technique for introducing a three-phase pressurized bubble column reactor in which a method of dispersing fine oxygen bubbles in the pressurization method is introduced.

In other words, the adsorption method using activated carbon is widely adopted. The activated carbon for water treatment mainly produced by carbonizing coconut shell has a large surface area and strong adsorption power, which is effective for removing organic substances, but its adsorption amount is limited, so the replacement or regeneration cycle is short. Had a problem.

In addition, in the conventional method, a sample of raw water stored at the time of chlorine addition and chlorine are introduced correspondingly, thus causing excessive input of chlorine due to sampling.
