Description

DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a method and an apparatus for treating well water, and more particularly to a method and an apparatus for treating well water used as surface treatment water for polishing electronic parts and the like.

[0002]

2. Description of the Related Art Conventionally, it has been considered that pure water is desirably used for surface treatment such as polishing of parts in an electronic parts factory, but pure water is difficult to obtain and is expensive. Therefore, groundwater can be used as easily available water. However, groundwater contains various germs, and algae are generated in the water tank, and cannot be used as treated water as it is. In addition, since slime is generated due to various bacteria, it is necessary to clean water tanks, pipes, related machines, and the like on a daily basis, and the labor and cost thereof greatly increase manufacturing costs.

[0003]

Therefore, well water contains various microorganisms such as microorganisms and algae, which proliferate by utilizing nutrients in the water, secrete adhesive substances such as polysaccharides, and are suspended and suspended in the water. The substance is fixed, and the dust in the air is mixed with the substance to form a sticky muddy substance. Since this floats in water, it is not only unfavorable as washing water for electronic parts and the like, but also adheres to or accumulates on water storage tanks, pipes, related machines, and the like, so that it takes time and cost for cleaning. Accordingly, it is an object of the present invention to sterilize microorganisms such as microorganisms in well water, remove organic substances such as aquatic plants serving as a nutrient source thereof, and obtain treated water that can be used as washing water for electronic components and the like. Specifically, it is a first object of the present invention to provide chlorine-treated groundwater containing various bacteria such as microorganisms, and to treat the sterilized water with far-infrared rays to obtain treated water separated from impurities. When the groundwater contains a large amount of iron, a second object of the present invention is to treat the groundwater with far-infrared rays to separate impurities and to make the treated water filtered by a rapid iron removal layer to remove iron. In addition, groundwater containing microorganisms and other germs is sterilized by chlorine, and the sterilized water is treated with far-infrared rays to separate impurities, filtered rapidly by a rapid iron removal layer, and further adsorbed residual impurities to electronic components. It is a third object of the present invention to provide a treated water that can be used as a washing water.

[0004]

According to the present invention, groundwater is pumped up and stored in a raw water tank 2, the water is sent to a chlorine sterilization tank 3, where the water is subjected to chlorine sterilization, and the sterilized water is transferred to the ceramic tower 4. The ceramic tower 4 is loaded with ceramic particles of a far-infrared radiator on a net, and when sterilized water passes between the ceramic particles, impurities are separated by the far-infrared treatment and water is removed. The cluster is made smaller, and the water is sent to the rapid iron removal tank 5, where the rapid iron removal tank 5 is filled with sand. When the water from which the impurities are separated passes through the sand, the impurities are filtered. Then, the iron content is adsorbed, and the filtered and iron-removed treated water is sent to the activated carbon treatment water tank 6, where the impurities that could not be removed in the rapid iron removal tank 5 are adsorbed by the activated carbon and supplied to the factory from there. It is a well water treatment method. The present invention relates to a raw water tank 2 for pumping up and storing groundwater, a chlorine sterilization tank 3 connected therefrom for piping by water and a chlorine sterilization treatment for water, and a pipe connected therefrom for piping.
A ceramic tower 4 in which ceramic particles of a far-infrared radiator are loaded on a net for the far-infrared treatment of the sterilized water, and a treated pipe from which impurities are separated by far-infrared treatment are connected by piping. The inside was filled with sand, thereby filtering the water passing therethrough, and the rapid iron removal tank 5 for adsorbing iron was connected to it by piping, and the inside was filled with activated carbon to adsorb residual impurities. This is a well water treatment device which is made up of an activated carbon treatment water tank 6, from which water is supplied to a factory.

[0005]

According to the present invention, groundwater is pumped up, (1) chlorine sterilization in a chlorine sterilization tank 3 and far infrared treatment in a ceramic tower 4, and (2) far infrared treatment in a ceramic tower 4 for rapid removal. (3) chlorine sterilization in a chlorine sterilization tank 3, which is subjected to a far-infrared ray treatment in a ceramic tower 4, rapid iron removal filtration in a rapid iron removal tank 5, and an activated carbon treatment water tank. There are three possible methods for further adsorbing residual impurities in step 6. The switching from the above (3) to (1) or (2) is performed by piping and valves so as to bypass unnecessary tanks. Therefore, the method (3) will be described here. First, groundwater is pumped up by a well pump and stored in the raw water tank 2, and the water is sent to the chlorine sterilization tank 3, where the water is sterilized using a chlorine concentration sufficient for ordinary tap water. The sterilized water is sent to the ceramic tower 4,
When passing slowly between ceramic particles, the ceramic tower 4
Impurities are separated by the action of far-infrared rays emitted from the ceramic particles of the far-infrared radiator inside, the clusters of water are reduced, and the treated water from which the impurities are separated is sent to the rapid iron removal tank 5 for rapid removal. When passing through the sand in the iron tank 5, the separated impurities are filtered to adsorb iron, and the activated carbon treated water tank 6 adsorbs and removes impurities that could not be removed by then. The treated water is supplied from the activated carbon treated water tank 6 to the factory. Rapid iron removal tank 5 and activated carbon treatment tank 6
In order to prevent clogging, a backwashing device is installed to periodically backwash impurities, iron and the like that have been adsorbed. The result of comparing the raw water quality of the raw water tank 2 with the quality of the treated water discharged from the last activated carbon processing water tank 6 is as follows, and it can be seen that the water quality has been improved. Raw water quality Treated water quality PH 7.4 PH 6.0-8.0 Fe 2.0 mg / l Fe <0.3 mg / l Mn 0.1 mg / l Mn <0.1 mg / l Hardness 53 Hardness 10 or less SiO ₂ 29 mg / l KMnO ₄ 1.5 mg / l Evaporation residue 110 mg / l Conductivity 60-80 Conductivity 10-20 Thus, the occurrence rate of algae was reduced to about one-twentieth of that of the conventional water tanks and others. The number of cleanings of the machine has also been reduced, and the number of cleanings that had been done every day until now can be reduced to once a month.
