Description

Brine or washing water sterilization purifier {Apparatus for purifying and sterilization saline water or washing water}

The present invention relates to a brine or washing water sterilization purification apparatus, and more particularly, to a brine or washing water sterilization purification apparatus to sterilize and reuse the bacteria of pickling brine or washing water used in the kimchi manufacturing process.

In general, pickled foods such as kimchi are prepared through a process of pickling in salt or salt water, basically using any vegetable. In the mass production process, this pickling process uses brine (salt) adjusted to a constant concentration to obtain a uniform pickling effect. The industrialized kimchi manufacturing process consists of screening, cutting, pickling, washing, dehydration, seasoning and packaging, and the contaminated brine from pickling and washing contaminates soil and water. It is the main cause.

The concentration of saline used in the pickling process is 4-20% and the amount of saline is about 130% of the cabbage weight. And the reuse of brine used is usually about 1 to 4 times. Currently, the daily production of kimchi produced in Korea is more than 300,000 tons, so the amount of salt water generated by pickling cabbage is 39 ~ 1.56 million tons per day. In particular, the small Kimchi manufacturing plant lacks wastewater treatment. Such saltwater adversely affects the normal growth of microorganisms if not properly treated with wastewater, causing soil and water pollution, causing environmental pollution. The salt used for pickling cabbage varies greatly with the season, but the average daily consumption is about 3 to 40,000 tons.

After salting Chinese cabbage or radish, the brine is mixed with various organic and inorganic ingredients extracted from these vegetables, along with various microorganisms, soils and other contaminants on the surface of vegetables. Therefore, this brine can no longer be used and is discharged through wastewater treatment.

In the mass production process, the amount of wastewater discharged daily is enormous, ranging from tens to hundreds of tonnes, and the waste and cost of treating this wastewater is enormous.

As a technology to recycle the brine, Korean Patent No. 10-37542 consists of a pickled cabbage washing tank, a three-stage metal treatment tank to filter the floating water, and a three-stage water treatment tank to filter the wash water again, a filter, and a sterilization treatment device. The three-stage water treatment tank consists of multiple stages of metal net, sand, and activated carbon, and the sterilization unit is composed of ozone or chlorine treatment unit. In the case of the above-mentioned Korean patent, the ozone treatment or chlorine treatment, which is the core, while undergoing the general processes of manure, water purification and filter treatment of suspended solids, lacks a detailed description of the ozone concentration and time. That is, too many microorganisms and contaminants are discharged according to the type of cabbage and the pollution level of the cabbage, and since they go through a uniform process without changing the active supply amount by ozone according to these discharges, they are actually polluted after 1, 2 times. This is serious and can't be used. Furthermore, the supply of ozone is separated from the system, making integrated control difficult for optimal sterilization and discoloration. In particular, the use of expensive filter material called activated carbon has virtually no economic feasibility.

Related prior art is Korean Patent No. 10-0668278.

The present invention is to provide a brine or washing water sterilization purification apparatus to reduce the discharged water by reducing the amount of salt used by sterilizing the bacteria of the pickling brine (salt) or washing water used in the kimchi manufacturing process.
