The RO concentrated water ozone reaction apparatus of the present invention comprises a reaction tank 10 having an inlet 11 and a discharge unit 13 and an ozone generator 13 installed in the RO concentrated water (raw water) And ozone dissolving means 20 for dissolving ozone.

In general, steel wastewater needs purification in order to discharge it, and RO (Reverse Osmosis) membrane is mainly used in the process of purifying the wastewater. When the wastewater is purified by this reverse osmosis method, purified water And pollutants gather to make RO concentrated water.

Such RO concentrated water contains a very high amount of COD material, and a separate purification process is required to purify such RO concentrated water.

Accordingly, the present invention is directed to a method of purifying RO concentrated water, comprising the steps of: introducing a RO concentrated water (raw water) into a reaction vessel (11) having a RO concentrated water (purified water) 10 are provided.

The RO concentrated water is concentrated water of a high pressure (about 8 Bar). When such high pressure concentrated water flows into the reaction tank 10, the reaction tank 10 becomes unstable due to the pressure, or the reaction tank 10 There arises a problem to be improved. Therefore, the present invention provides the depressurizing means 111 in the inlet 11 to lower the pressure of the raw water to about 2.5 Bar so that it can be introduced into the reaction tank 10.

At this time, the higher the pressure of the raw water, the higher the solubility of ozone from the ozone dissolution means described later. Therefore, the reaction tank 10 can withstand the pressure and the pressure is reduced to a pressure of about 2.5 Bar .

In the RO concentrated water ozone reactor (A) according to the present invention, the ozone dissolving means 20 is installed in the inlet portion 11 provided in the reaction tank 10, Respectively. Therefore, the ozone is continuously introduced into the raw water flowing into the reaction tank 10, so that the COD content in the raw water can be reduced and discharged to the purified water as shown in the following reaction formula.

Reaction formula

COD + O 3 - > H 2 O + CO 2

It is also important that the time for which the raw water stays in the reaction tank 10 (reaction time) increases in order for the raw water to react as described above. To this end, the reaction tank 10 according to the present invention includes a plurality of baffles 15 .

More specifically, it is preferable that the obstruction plate 15 is provided in a zigzag shape in the reaction tank 10, thereby increasing the time taken for the fluid to move to the discharge unit 13, So as to improve the reaction effect.

The COD amount and the ozone amount of the purified water discharged through the discharging unit 13 are measured and the COD of the COD reference value or more is measured The purified water is sent to the flow path 17 connected to the ozone dissolution means 20 so that the purified water can flow into the reaction tank 10 through the inlet portion 11 again. When COD below the reference value is checked by the inspection unit 133, the COD is discharged through the discharge path 131. The discharge unit 13 (particularly, the discharge path 131) further includes a UV reaction tank 135 The purified water is sterilized once through ultraviolet rays to be finally discharged.

The RO concentrated ozone reaction apparatus A further includes a bypass means 30. More specifically, the reaction vessel 10 is provided with bypass discharge units 31 and 13 , And the discharge port (13) is connected to the flow path (17).

This is because when the purified water discharged through the discharge unit 13 is inspected for the amount of COD by the inspection means 133, a temporal loss occurs. In this case, the raw water in the reaction tank 10 is supplied to the reaction tank 10 There is a problem that it can be settled.

Therefore, the raw water can be circulated to the ozone dissolving unit 20 through the bypass discharge units 31 and 13 without causing the raw water to stay in the reaction tank 10, thereby redissolving the ozone, It is possible to prevent the raw water from staying in the reaction tank 10 and to improve the purification efficiency.

Wherein the COD is discharged through the discharge passage (131) of the discharge unit (13) when the COD is below the reference value in the purified water.
