Description

Technical Field [0001] The present invention relates to a saline wastewater releasable apparatus and a saline wastewater treatment method using a salt water reuse apparatus and a salt water reuse apparatus,

The present invention relates to a salt water reuse apparatus and a salt water treatment method using the salt water reuse apparatus, and more particularly, to a salt water reuse apparatus and a salt water treatment method using the salt water reuse apparatus, which purify and recycle saline water generated in pickling and washing processes It is about.

Generally, brine produced in the pickling process in kimchi manufacturing process is contaminated with various foreign substances and bacterial nitrate, and the brine becomes acidic in the pickling process. In this salting process, the salting process is performed using salt water having a salinity of 12% to 16%. The saline water in a clean state is reused in the salting process three to five times depending on the degree of contamination and is then disposed of .

Since the salty water that is reused many times in this way usually has a salinity of 10%, considering that the salinity of the seawater is 3% to 4%, it is waste disposal with diluted water, .

In order to solve such a problem, conventionally, a purification apparatus using a filtration method using a filter or a membrane has been used. However, since the replacement period of the filter is short and the purification apparatus is easily corroded due to high saltiness of the pneumatic water, The cost was too much and the cost-effectiveness was insignificant.

In addition, even in the tofu production plant, the bean sprouts plant, and the vegetable washing plant, the rinse water to be discarded through the rinse process necessarily occurs, but even if the saline rinse is not included in the rinse rinse water, There is a problem in that water and maintenance cost are excessively increased, and there is a hygienic problem that the brine used for salting is contaminated with various bacteria and the like, so that food is exposed to the pollutant when reused without filtration.

The first filter filters fine contaminants more than the third float removed by the precipitation filtration unit 105 and displays the internal pressure caused by the contaminants on the display unit 201 of the output unit 200, An alarm is generated through the alarm unit 202. [0033] FIG.

When the internal pressure is equal to or higher than the set reference value, the plurality of first filter units 106 are sequentially stopped, and the first filters are sequentially replaced, so that the process proceeds without interruption.

Next, the multimedia filter unit 107 filters the contaminants by at least one of sand, gravel, and activated carbon. The multi-media filter unit 107 ), The mucous contaminants are filtered.

Next, the second filter unit 108 filters the filtered water discharged from the multimedia filter unit 107 into a second filter, and the second filter is finer than the first filter So that contaminants which can not be removed by the first filter filtering unit 106 and the multimedia filter filtering unit 107 are filtered.

Next, the third filtered filter 109 receives the filtered water discharged from the second filtered filter 108 and filters the filtered water through a third filter. The third filter is provided as a finer filter than the second filter So that contaminants that can not be removed by the second filter filtration unit 108 are filtered. Here, when a plurality of filters are connected in parallel to each other, the third filter filtering unit 109 stops the entirety of the third filter filtering unit 109, and sequentially switches the third filter ,

Next, the ultraviolet sterilizing unit 110 receives the filtered water discharged from the third filter filtering unit 109 and irradiates ultraviolet rays to the filtered water to sterilize the filtered water.

Next, the acidity of the sterilized filtrate discharged from the ultraviolet sterilizer 110 is measured by the acidity sensor 111, and the acidity measurement data is transmitted to the controller 500. The controller transmits the measured acidity measurement data To be stored in the memory (300).

The filtered water thus treated is stored in the treatment water storage section 130 and the water level is measured by the third level sensor 153 of the treatment water storage section 130. If the level of the third level sensor 153 is higher than the set water level, it is discharged to the raw water or the salt water reuse apparatus is turned off to protect the salt water reuse apparatus.

On the other hand, if the acidity is higher than the predetermined acidity, the neutralization treatment unit 112 is supplied with the neutralizing agent into the drum filtration unit 102 to adjust the acidity and change to alkaline water if necessary.

And supplies filtered water discharged from the third filter filtration unit 109 to the second bubble filtration unit 104 and the precipitation filtration unit 105 through the backwash water supply line. At this time, the second bubble filtering unit 104 is supplied through the blower 115 in a blowing manner.
