Description

An ozone oxidizing system

The present invention relates to an ozone oxidation system, in particular, the sludge is effectively purified during the process of sequentially passing the waste water introduced into the screen and the settling tank, and the purified water can be reused such as car washes. Relates to an oxidation system.

Recently, due to the rapid development of industrial civilization, water pollution by waste water is getting serious day by day, and various methods of oxidation and sterilization using ozone have been devised.

However, since the conventional methods of oxidizing and sterilizing ozone use ozone to inject bubbles into a fixed tank using an acid pipe or an ejector, not only ozone generation occurs but also the contact efficiency of waste water and ozone is low. The contaminants could not be effectively purified and the recycled treated water could not be recycled or complex equipment such as automatic valves and compressors were needed for backwashing.

Therefore, the object of the present invention was devised in view of the conventional problems as described above, sludge is effectively treated in the process of the waste water flowing into the screen and the sedimentation tank in order to pass through a series of devices, the treated water is washed, etc. It is to provide an ozone oxidation system that can be reused or discharged.

As a means for achieving the above object, the present invention, screen and sedimentation tank for removing the floating foreign matters, such as oil and sedimentation large sedimentation material when the waste water containing sludge is introduced;

An ozone contact pump for suction-mixing and pumping the waste water introduced into the sump tank through the screen and the settling tank and the ozonation air generated from the ozone generator;

An ozone contactor which, when the waste water pumped by the ozone contact pump flows into the inside, contacts with ozone to oxidize contaminants contained in the waste water by ozone reaction and sends it to a continuous sludge removal device;

An activated carbon filter for pumping activated sludge from the sludge-removed wastewater through the continuous sludge removal device to filter the activated carbon and supplying the treated water to a reuse tank;

 When the sludge removed wastewater collected in the state installed between the activated carbon filter and the multi-filtration pumping tank is collected at the bottom of the filtration pumping tank, the activated carbon filter is connected to the activated carbon filter and the sludge is accumulated in the multi-filtration pumping tank. It is a basic feature of the technical configuration that is composed of a backwash pump capable of rotating left and right to backwash a multifiltration pumping tank.

Hereinafter, exemplary embodiments of the present invention will be described in detail with reference to the accompanying drawings.

If the wastewater used in the wastewater purification treatment apparatus of the present invention also flows into the sump tank, the basic context for purifying and supplying it to the reuse tank through a series of processes is the same as before.

However, the present invention allows the waste water to be more effectively treated, which is the screen and the settling tank 100, the collection tank 200, the ozone generator 300, the ozone contact pump 400, the ozone contactor as shown in FIG. 500, a continuous sludge removal apparatus 600, a pumping tank 700, an activated carbon filter 800, a recycling tank 900, and a backwash pump 910 are basically mobilized.

Screen and sedimentation tank 100 is a device for removing floating foreign substances such as sedimentable material and oil when sewage-containing waste water is introduced, the reuse tank 900 is purified through a series of processes in turn The treatment water is stored in such a way that it can be reused.

The ozone contact pump 400 performs a role of suction-mixing and pumping the ozonated air generated from the ozone generator 300 and the wastewater introduced into the collection tank 200 through the screen and the settling tank 100.

When the ozone contactor 500 is introduced into the waste water pumped by the ozone contact pump 400 to contact with ozone to oxidize the contaminants contained in the waste water by the ozone reaction to send to the continuous sludge removal apparatus 600. It is composed.

Activated charcoal filter 800 has a configuration of supplying the treated water to the reuse tank 900 by filtering the activated carbon filtered and purified when the sludge is sludge is removed to the pumping tank through the continuous sludge removal apparatus 600.

The backwash pump 910 is used to be installed between the activated carbon filter 800 and the multifiltration pumping tank 700. When the wastewater from which sludge is removed is collected at the bottom of the multifiltration pumping tank 700, it is activated carbon filter 800. Activated carbon filtration by connecting with, and when sludge is accumulated in the multi-filtration pumping tank 700 is configured to rotate left and right to backwash the back of the multi-filtration pumping tank 700.

Here, the screen and the settling tank 100, the collection tank 200, the ozone generator 300, the ozone contact pump 400, the ozone contactor 500, the continuous sludge removal apparatus 600, the multi filtration pumping tank 700 ), One of the activated carbon filter 800, the recycle water tank 900, one of the backwash pump 910 is a technical configuration of the normal use, so a detailed description thereof will be omitted. However, the present invention has a series of systems that allow the sludge contained in the waste water to be more effectively removed while passing through the series of devices as described above.

Reference numeral 510 denotes an ozone decomposing device for removing ozone remaining in the ozone contactor 500.

In order to use the present invention configured as described above, when the wastewater containing sludge flows into the screen and the settling tank 100, the screen and the settling tank 100 are primarily foreign substances such as oil having large sedimentation property and oil. Remove it.

The waste water introduced into the sump tank 200 through the screen and the settling tank 100 is pumped to the ozone contactor 500 by the ozone contact pump 400, in which the waste water and the ozone generator 300 introduced into the sump tank 200. ) Ozone air generated from) is inhaled and mixed, and the waste water mixed with ozonated air contained in the waste water during the mixing process is oxidized by direct and indirect reaction of ozone because ozone is evenly contacted with pollutants in the waste water. do.

The waste water oxidized through the ozone contactor 500 is introduced into the continuous sludge removal apparatus, and sludge is removed, and the sludge is removed, and the waste water is introduced into the multi-filtration pumping tank 700. At this time, ozone remaining in the ozone contactor 500 is removed by the ozone decomposing device 510.

Waste water introduced into the bottom of the multi-filtration pumping tank 700 is pumped by the backwash pump 910 into the activated carbon filter 800, and activated carbon is filtered, and the filtered treated water is supplied to the reuse tank 900. On the other hand, when sludge is accumulated in the multi-filtration pumping tank 700, the reverse washing pump 910 is reversely connected to the reuse tank 900, and the multi-filtration system using the treated water stored in the reuse tank 900. What is necessary is to backwash the inside of the pumping tank 700.

As described above, according to the present invention, the sludge is effectively purged in a process of sequentially passing the waste water introduced into the screen and the sedimentation tank, and the purified water can be reused like a car wash. There is.

The present invention has been described above with reference to specific preferred embodiments, but the present invention is not limited to the above-described embodiments, and various changes and modifications may be made by those skilled in the art without departing from the gist of the present invention. Make sure you can.
