Description

{PRESSURE WATER PURIFICATION FACILITY FOR WATER AND SEWAGE WORKS}

The present invention relates to a pressurized water purification plant for water supply and drainage, and more particularly, to a water purification facility for water supply and drainage disposed in a facility maintenance room equipped with an access security device for accessing only authorized facility administrators, The water purification facility includes a pump for forcibly supplying water by a predetermined pressure; A plurality of antibacterial filters for filtering foreign substances contained in water forcibly supplied by the pump and inhibiting bacterial growth; A sedimentation tank having a structure in which water to be dribbly supplied through the antibacterial filter is sedimented and filtered through a plurality of activated sludge bodies filled with an upper filtration screen and granular activated carbon at the bottom; A filtration tank having a structure in which filtered water filtered down through the settling tank is supplied from a lower portion of the partition wall and is moved upward to be purified by passing through a plurality of screen net made of microfine fibers; And a sterilizing tank having a structure in which purified water purified through the water tank is supplied from the upper part of the partition wall and sterilized by the microwave action of the silver electrode so that the water is passed through a plurality of filtration and sterilizing apparatuses And more particularly to a pressurized water purification plant for drinking water which not only can provide more efficient constants but also can save costs by using less chemicals and can obtain better quality constants in smaller areas.

In the case of waterworks, water or ground water is often disinfected with chlorine, but water can not be supplied as a drinking water without removing harmful impurities such as turbidity and bacteria in the water. In this way, purification of water is called constant, and the place of water purification is called water purification field.

On the other hand, in the conventional wastewater system, the coagulant is added to coagulate the impurities contained in the wastewater, so that the coagulant is allowed to settle in the settling tank for a long time, and the purified water on the upper side is passed through the filtration device again to obtain fully purified water .

However, when a large number of sedimentation tanks are installed in a large scale, the volume and the installation area of the sedimentation tanks are large and the space occupies a large space. Therefore, the waste water must be passed through a number of sedimentation tanks several times, The precipitation time becomes very long, and the time for purifying the wastewater is considerably long.

Also, in the case of domestic water purification plants, the water quality of the domestic water purification plants is very large when the seasons are divided into two groups. Various kinds of medicines have been used and there has been a problem of using expensive fixed-dose input facilities for each kind of medicines.
