Abstract

The present invention relates to a method of reusing wastewater of a facility with a high amount of water and a process of using the same. In particular, the present invention re-purifies sewage discharged from a water-intensive facility such as a hotel and a swimming pool, and reuses the wastewater in a facility for purification of the wastewater. The effluent is treated and discharged to be purified and finally reused as water in a place where a large amount of water is needed, such as a swimming pool.

The sewage discharged from the pool of these facilities and the sewage discharged from the sewage purification facility are treated separately or in parallel with the ultrafiltration membrane and reverse osmosis membrane, and then sterilized by ozone treatment and chlorine treatment. How to produce high-quality purified water and reuse it back to the pool water and the like, and the sewage (10) through the sewage purification plant 20, the final discharge (100) through the coagulation and sedimentation device 300 through the sand filter (310), Treated with activated carbon filter 320, precision filter 330, ultrafiltration membrane module 340, and through the storage tank 350 for water quantity control, high pressure pump 360, reverse osmosis membrane module 370, ozone sterilizer 380, Chlorine injection device 390, the final storage tank 400 to reuse (410) technology.

Description

Sewage recycling method of facility with high water usage and its use process

The present invention relates to a method of recycling sewage of facilities with high water consumption, and a process for using the same. It is to purify the discharged water discharged after treatment and reuse it as water in the place where water is required as an equivalent, such as a swimming pool.

In general, large buildings, sports centers, and deluxe hotels have a lot of physical and recreational facilities such as swimming pools. These facilities require a lot of water.

However, during periods of poor water supply due to drought or other reasons, or in areas with heavy water use in such areas, these facilities may have to be removed from public authorities when water conservation and some facilities are taken into consideration, or even when water shortages are more severe. Because of the many restrictions on the use of water, the use of water is effectively suppressed.

In addition, the sewage discharged from these facilities is generally treated as a sewage purification plant and discharged. If the discharged water is reused as it is in the unit facility, it is practically impossible to use because it causes many problems in hygiene, safety, and water quality. Therefore, in order to reuse the effluent from the sewage purification plant, it is necessary to go through the treatment facility once again, and facilities such as swimming pools, which have a large amount of water use, have a relatively low pollution rate unlike other sewage sources. Since conditions are in place, it is necessary to create a plan that can use them effectively.

Therefore, the present invention has been made in order to solve the above-mentioned contents as a process for reusing sewage discharged from large buildings, hotels and sports facilities with a large amount of water use, in particular the sewage and sewage discharged from the pool of these facilities It is a process to treat sewage generated in the purification facility individually or in parallel. After treating sewage with ultrafiltration membrane and reverse osmosis membrane, sterilization such as ozone treatment and chlorine treatment finally produces high-quality purified water and pools it again. Its purpose is to reuse it as water.

Referring to the present invention with reference to the accompanying drawings the configuration and effect as follows.

1 shows a conceptual diagram of a conventional sewage treatment process.

In general, the treatment of sewage (10) generated in a large building or facility is discharged by treating the sewage treatment facility (20) using a long-term aeration method and other biological treatment methods.

Figure 2 shows a process diagram of the present invention for directly recycling the sewage generated in the pool of the present invention, the pool sewage is discharged from the pool 200 is compared to the general household sewage because the water quality is relatively good for reuse The treatment is easy and the quality of the recycled water is good.

Therefore, by treating the ultrafiltration membrane module 220 that can remove not only the fine filter 210 and fine colloidal components to remove the suspended substances present in the pool sewage 200, but also fine materials of about 0.001㎛ size Purify the pool sewage (200).

At this time, the ultrafiltration membrane module can use any type of ultrafiltration membrane module regardless of its type.

Finally, through the ozone sterilization device 230 for sterilizing microorganisms and pathogens that may remain in the purified water and the chlorine injection device 240 for maintaining residual chlorine for the safety of reused water, the final safe reuse water Produced and stored in the storage tank 250 is used as the pool water 300, and if necessary, it is composed of a process that can be reused as landscape water.

And when excluding the sewage discharged from the pool occupation is as shown in FIG.

In this regard, Figure 3 shows an integrated process flow diagram for reusing the effluent treated in the septic tank as a conceptual diagram of the present invention, and at the same time to reuse the filthy water discharged from the pool as needed.

Here, it is composed of a process of adding the reverse osmosis membrane module for removing the inorganic substances contained in the treated water, such as filthy water, integrating FIG. 1 and FIG.

The flow chart shows that the sewage 10 is finally discharged through the sewage purification plant 20, through the coagulation and sedimentation apparatus 300, through the sand filter 310, the activated carbon filter 320, the precision filter 330, and ultrafiltration. Treatment with the filtration membrane module 340 and through the storage tank 350 for the water quantity control, the high pressure pump 360, reverse osmosis membrane module 370, ozone sterilizer 380, chlorine injection device 390, the final storage tank 400 It consists of a process of reusing (410) through.

As described above, by applying the method devised in the present invention, it is possible to overcome the difficulties caused by the lack of water by reprocessing sewage as an alternative source of water in regions or seasons that are experiencing water shortages, and to reduce the amount of tap water used in normal times. It is an effective solution.
